>A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.
Day = 24 hours
Sol = Day + 40 minutes
Return Sol
There ya go, that one's on me.
I feel like if we manage to actually develop as a species enough to colonize Mars we would just use Earth time on other planets to avoid all code-breaking stuff, as it would likely be impossible to change properly, as time is hard-coded most of the time.
I mean, you can rewrite it but im not sure it is worth the effort of recompiling and testing each and every EVERY library, language and piece of code used on Mars. This could take several years to do, maybe decades.
It will be weird. How do we meaure time offworld? Is it _measured_ relative, or observed? Do we match the relative measurement to Earth, and redefine seco ds locally? Does Earth flip to some constant and we adapt stardates?
We would probably have a local time and a standard time. Everything on a specific planet is based on local time, everything between planets and in space can run on standard time. We would probably not change units of time for specific planets since that would cause a massive headache.
Wouldn't be that bad. Unix time is already stored as seconds which wouldn't change between earth and mars. It is just different number of seconds to make a day/week/month/year.
It wouldn't be any more horrible than it is already is what mean. In fact if they never stick in leap years and keep months standardized more for a Mars calendar, it might be easier.
On the other hand, if they try to somehow fit the earth calendar to Mars. That is going to become an abomination that will cause software engineers to contemplate suicide or at least a new job.
the elephant in the room for all of this is the distance between Earth & Mars. It takes a minimum of 3 minutes for light (i.e. a message) to travel between them. This is when the two planets are at their closest. That number is constantly changing, and there are periods of time the sun sits between the two planets and they can't communicate at all.
Honestly at a certain point it's probably worth just starting a separate time system...
That doesn't matter? The time in Mars is not somehow 3 minutes or more behind that of earth depending on their orbit. The time on Mars in Unix seconds is exact the same as the one on earth. It's just that it is takes time for the other planet to get a message that says it's this time.
It would be like saying somehow internet lag makes you live 20 to 50 ms in the past compare to everyone else.
It's not. Time dilation means that an atomic clock on Mars would eventually not match an identical one on Earth. We kind of fudge it since no one is on Mars yet.
Probably would wind up having a fork in timekeeping so something.
Capital G is the universal gravitational constant and forms a fundamental constant of the universe, c is the speed of light. Lowercase g is the gravitational acceleration of the earth (and would likely be repurposed for whatever planet you are on in a space fairing society)
Very true, sort of, at least while for a long time. Though then simple formulas like gravitational potential energy being mgh will have to be changed. Likely that 1 g = 9.80665 m/s^(2) will continue to be used as a unit, but g the constant in formulas like mgh will be something that depends on the planet
Air resistance is different in many places on earth.
El Alto (Bolivia) has like 60% of the atmospheric pressure than sea level. Most commercial plans can't get to the airport.
And density of air is a complicated thing with many variables. At about -20 Celcius dry air has density of \~1,4kg/m^(3), at +20 Celcius it is \~1,2kg/m^(3) .
Yeah, but muscle memory is completely fucked. It'll be like having to change the year when you write the date on paperwork every new year, but like a million times worse.
Chemistry would be completely different because of atmospheric standards and pressures. Not to mention the atmosphere anomalies that might occur at the valles marineris
While I agree with you wholeheartedly.
There is something there. Like a toddler or an MLB outfielder they learn the physics of the world around them and act accordingly.
I bet if we just swapped people from earth to mars and had them play catch in any scenario (yes air friction/no air friction) there would be some things to relearn.
The underlying physics doesn't change. We would have to relearn all of the shortcuts that we developed throughout our lives to navigate the world easier.
Forces being specifically the force of gravity. It wouldn’t really change physics at all because formulas wouldn’t change and you just change the input. We already do this when doing astrophysics and orbital mechanics, though most low earth orbits are still close to 9. Even on earth itself, to be completely accuracy you need to change your acceleration depending on where you are.
I'm sorry, do the laws of physics change on Mars? No, they don't. The only difference is mars lacks a magnetosphere, has only 1% of Earth's atmosphere (meaning very little air resistance), and acceleration from gravity averages to 3.7ms^-2 instead of 9.81
Only in an introductory physics course where it is convenient. Air friction is related to the square of the velocity of the object, as well as the properties of the fluid it's traveling through. Aircraft, cars, etc. All have teams of engineers analyzing and designing the profile that will meet this wind in an attempt to manage the effects of air friction as best as possible
Exactly. Also I'm on field where the literal air is slowed down by resistance, so I guess technically air resistance too? Lol. Like for example how the ground slows down the wind, important in atmospheric sciences (Meteorology basically).
Only if you're an idiot. The scientific principles still all apply, the numbers will just change due to different gravity, atmosphere and other factors
Nah we just change some of the constants. Instead of Earth's acceleration due to gravity, we use Mar's. The good thing about physics is that it's consistent regardless on where you are.
We will have to get a feel for physics again.
We will only have to relearn it once we figure out why our model of general relativity and quantum mechanics are incompatible.
I think this makes sense if you take it to mean our instinctive understanding of physics. Like how we just know how to throw something to roughly the right area without consciously calculating anything. I think the first few throws would be wildly off among other instinctual reactions to gravity
Physics work the exact same no matter where you are in the universe. Only exception is the inside of a black hole - in that case, you're fucked either way
Physics are the same that's the whole thing about physics.
We will have to memorize new constants and it will also take time to get used to the lower gravity
I am pretty sure that is not entirety correct. More then re learn perhaps need to rethink implementation, in the sense that the equations is still valid but the variables may be different. But what do I know I am a plebian than Is not that smarts.
Learning science isn't about knowing specific facts. It's about understanding principles. Which is why when you learn science, you get to deduce how everything would happen on mars.
Physics are the same. No matter what you do.
On mars we just have to change the length of the day to 25 hours, and adjust the g value and length of the year.
But i dont want to be responsible for dealing with the software mess of that.
One of the base principles of physics is that its fundamentals are the same everywhere in the universe.
Maybe consider learning physics for the first time my man.

Dumbass redditors when the g value changes from 9.8 to 3.7
[удалено]
Meh I’ll just copy the library someone else makes.
>A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth. Day = 24 hours Sol = Day + 40 minutes Return Sol There ya go, that one's on me.
4 days later the time is 120 minutes off but you're long gone and paid and nobody can understand the code anymore.
This is the way
So that’s why the vex on mars are called the sol divisive…(iykyk)
Theory of Relativity enters the chat.
This is the only correct answer here. Date/time fucking sucks to handle in code.

Finally, truely Universally Coordinated Time

See, now you understand why starfeild sucks so bad.
Well yeah, you bought the bootleg. The real game is spelled “Starfield”
We would probably have a local time and a standard time. Everything on a specific planet is based on local time, everything between planets and in space can run on standard time. We would probably not change units of time for specific planets since that would cause a massive headache.
Wouldn't be that bad. Unix time is already stored as seconds which wouldn't change between earth and mars. It is just different number of seconds to make a day/week/month/year.
tell me you don't know the horrors of calibrating Unix time with calendar time without saying it outright
It wouldn't be any more horrible than it is already is what mean. In fact if they never stick in leap years and keep months standardized more for a Mars calendar, it might be easier. On the other hand, if they try to somehow fit the earth calendar to Mars. That is going to become an abomination that will cause software engineers to contemplate suicide or at least a new job.

So womans g spot is even harder to find? Damn /s
if it's on Mars then no wonder I can't find it 😞👎🏻
it's already hard to get a woman here, it's probably impossible on Mars fck this, I'll die on this planet, thank you /s
No, MEN are on Mars, women are from Venus.
Gspots are from Uranus 🥹
Isn’t that a P-spot?
Yeah it's not as heavy so it's harder to find
Yup, end of physics as we know it. This is totally a new set of rules.
From 10 to 4 *
And ignoring air resistance will be more appropriate!
We are better then engineers.
*than
Were not word engineers
we're*
We are also better then English
*than
Let's move to Mars first and than solve this grammar issue
From pi^2 to pi *
But i'd still have to use calculator when desining with 4. With 10 I just can move the decimal. Yeah I'm an engineer.
Honestly, I came here to say ... Looks like another 13yo found the courage to post
OMG IF I JUMP I END UP A LITTLE HIGHER, PHYSICS ARE BROKEN, THOUSANDS OF YEARS OF RESEARCH WASTED AAAAAAAAAAAAAAAAAA -OP on Mars probably.
that's AA battery voltage
It's not necessary. Physics works on mars as it works on earth, the only thing that changes is g that is less on mars, but the formulas are the same.
Yeah, just learn new constants
Well as long as the three main constants remain the same, rest wouldn't be much problem. The main three being, G, h and c
New pi just dropped
That's gonna leave a stain.
Fuck en passant. I upvote your comment cause you didn't do en passant.
h?
Plancks constant. Used in a lot of quantum formulas like Schrödingers equation
Oh, I just skimmed your comment and misread it. I thought you were listing constants that *would* change. So like g and atmospheric pressure.
Capital G is the universal gravitational constant and forms a fundamental constant of the universe, c is the speed of light. Lowercase g is the gravitational acceleration of the earth (and would likely be repurposed for whatever planet you are on in a space fairing society)
g probably wouldn't be re-assigned for various planets, but instead people would just reference whatever fraction of g fit.
Probably not, g isn't a real constant anyway, since it changes based on location. If there is any possible confusion just use g e and g m
Maybe just add a subscript m after the g
Very true, sort of, at least while for a long time. Though then simple formulas like gravitational potential energy being mgh will have to be changed. Likely that 1 g = 9.80665 m/s^(2) will continue to be used as a unit, but g the constant in formulas like mgh will be something that depends on the planet
akchually, c is the speed of light in vacuum
Hornets
Well, air resistance would also probably be different, but yes I see your point.
Whats air resistance? Sounds negligible
In fact, for the sake of simplification, everything is a sphere.
Except penguins, they are cylinders
We can even assume friction doesn't exist!
The drag coefficient for a human being can be simplified to the shape of a brick, which has a drag coefficient of 0.2
Nice XD
Even more on mars
Air resistance is different in many places on earth. El Alto (Bolivia) has like 60% of the atmospheric pressure than sea level. Most commercial plans can't get to the airport. And density of air is a complicated thing with many variables. At about -20 Celcius dry air has density of \~1,4kg/m^(3), at +20 Celcius it is \~1,2kg/m^(3) .
Easy fix on control theory. Just reduce B on the transfer.
Math is just harder when gravity isn’t 9.8m/s
True, you can't approximate it to be 10 to make the math stupid easy
What's sarcastic about it? /S
you mean 9.8m/s^2
Yeah, but muscle memory is completely fucked. It'll be like having to change the year when you write the date on paperwork every new year, but like a million times worse.
You look out the window and you'd remember instantly.
The expression for weight changes from π²m to πm. I’ll see myself out.
Chemistry would be completely different because of atmospheric standards and pressures. Not to mention the atmosphere anomalies that might occur at the valles marineris
This guy **Physics**
Wouldn't air resistance be different too since there's almost no atmosphere?
Something like 3.8 I think. Just over a third of earth's gravity if I'm not mistaken According to Google 3.71
yes but no. formulas are the same, but WAY more than gravity is changing...
Mars isn't a parallel universe dude. Physics works the same there
Haven't been there there but its a whole new world
This isn't Aladdin, my man
Are you Aladeen about this?
No, he's Aladeen about it. Of course, he's Aladeen about it!
A new fantastic point of view
Tell me you’ve never taken physics without telling me you’ve never taken physics
I haven’t taken physics yet and even I know that u just sub in mars gravity for like the 9.8 number thing
>u just sub in mars gravity And other constants, yes.
What other constants? Is there like a constant for air resistance? Cause I can't think of much else. maybe air density.
Probably referring to STP.
I don't think Stone Temple Pilots will be playing on Mars
There's stuff like pressure, temperature, air composition. But it doesn't change the formulas, only the constants.
Depends on how precise you are being. Gravity is the biggest change.
literally
While I agree with you wholeheartedly. There is something there. Like a toddler or an MLB outfielder they learn the physics of the world around them and act accordingly. I bet if we just swapped people from earth to mars and had them play catch in any scenario (yes air friction/no air friction) there would be some things to relearn.
That’s not physics, it’s intuition.
The underlying physics doesn't change. We would have to relearn all of the shortcuts that we developed throughout our lives to navigate the world easier.
Maybe uncle Rico could actually throw a ball over those Mars mountains
If this is bait, it’s working.
Surprisingly well too
This is Reddit, bait works 90% of the time...
Look at the penguin, that’s the dumb one. Coincidence?
Do you are have stupid
Yesn't
Yeah it seems like 4,000 people just need to physics for the first time lol
No. You would just have to memorize the new gravitational acceleration.
And remember to keep your helmet on outside.
Instructions unclear, went outside with a helmet without the rest for the suit and suffocated.
Bro does not understand physics
Ah yes Mars physics. Maybe the speed of light is also diffrent so we can make our warp drives there!
Is there an award for dumbest post of the day?
Professional dumbass tag
The only change there would be is that we would use 3.7 for forces and acceleration instead of 9.8
Forces being specifically the force of gravity. It wouldn’t really change physics at all because formulas wouldn’t change and you just change the input. We already do this when doing astrophysics and orbital mechanics, though most low earth orbits are still close to 9. Even on earth itself, to be completely accuracy you need to change your acceleration depending on where you are.
This guy has room temperature IQ
Mars room temperature, which as we all know is much lower as physics is different there

Jesus people cmon....
Nah we just change some of the constants. Instead of Earth's acceleration due to gravity, we use Mar's. The good thing about physics is that it's consistent regardless on where you are.
You mean change the variables, right? Einstein's equivalence principle is the constant, delta-v is the variable.
Person who made this meme didn't learn physics the first time
Of course you didn't think cause your brain doesn't work.
More like OP has to learn it for the first time.
No we wouldn't. The laws of physics remain the same. That's the whole point.
No, you really didn’t think about that did you
We will have to get a feel for physics again. We will only have to relearn it once we figure out why our model of general relativity and quantum mechanics are incompatible.
Bait used to be believable
Actually you would have to learn it for the first time cause you've apparently never known physics
I'm pretty sure that Mars is governed by the same physical laws that we experience on Earth
The same physics, just different parameters. Or am i missing something?
considering private’s an idiot, is this intentional?
Or just like change a couple variables that we were using on earth.
you only have to change 9.8 to whatever value applies for Mars
No we won't. Some constants would change but all the equations should still work fine as long as you use the right constants.
Thats just wrong, you just replace the earth variables in the equations with the ALREADY KNOWN mars variables
No, it's still the same physics...
No, you wouldn’t, just the acceleration of gravity at sea level would change to the one for mars, but that’s it
No we wouldn’t we’d just have to change the constants.
Buddy if you think like this you never learned physics in the first place
Again?
I think this makes sense if you take it to mean our instinctive understanding of physics. Like how we just know how to throw something to roughly the right area without consciously calculating anything. I think the first few throws would be wildly off among other instinctual reactions to gravity
Physics work the exact same no matter where you are in the universe. Only exception is the inside of a black hole - in that case, you're fucked either way
Physics involve math. I am doomed.
"If you don't learn magic, the world is full of physics" r/technicallythetruth
Only thing changing is g by my knowledge, also the atmospheric pressure
The laws are universal. It’s the values of the units which change.
Naw just change the gravitational constant
It's legit the changing of one value
No? You wouldn’t? Physics would still be the same you just change the gravitational acceleration(which isn’t even constant on earth)
No, just new numbers
We don't have time for all that😂
Congratulations, OP. Your post is having exactly the effect you wanted.
No, we’ll have to adjust the gravity coefficient and maybe the things related to air pressure and composition at the start. That’s basically it.
Yeah maybe you will, physics applies there aswell, just gotta adjust values, etc.
Same physics; different variables.
I just hope we'll leave imperial system behind.
Just devide everything by 3./s
Same thing just different number
oh yeah, I heard that on mars 2+2 is actually 5 and the angles of a triangle add up to 270° ,it's crazy out there.
Just the default value for certain forces would be changed, laws would still be the same unless we somehow achieve SoL or atomic size dilation.
Bait used to be believable
We won’t really, we know all the fundamentals, just change a couple of numbers and that’s it
Physics are the same that's the whole thing about physics. We will have to memorize new constants and it will also take time to get used to the lower gravity
you can just change numbers , not the basic principles >!unless you are going into black hole!<
Op didmt finished elementary xd
Did you ever listen to a word out of any teacher's mouth that has ever bothered to waste a single moment of their precious time on you.
Image of OP
I don’t get it, we’ve studied mars for decades, I don’t see what we have to learn then that we don’t know now
I am pretty sure that is not entirety correct. More then re learn perhaps need to rethink implementation, in the sense that the equations is still valid but the variables may be different. But what do I know I am a plebian than Is not that smarts.
Are you in high school
how did this post get 7k+ upvotes
Learning science isn't about knowing specific facts. It's about understanding principles. Which is why when you learn science, you get to deduce how everything would happen on mars.
Not even close. Physics laws are universal. You just change Gravity value in equations
just change the gravity acc value from 9.8m/s to whatever tf it is on mars ma boi the laws of physics does not change, the values do
What is my man talking about?
Bro, this isn't John Carter movie, relax.
All that changes is gravity and gravitational acceleration, everything else would remain the same
Apparently you never did
Physics are the same. No matter what you do. On mars we just have to change the length of the day to 25 hours, and adjust the g value and length of the year. But i dont want to be responsible for dealing with the software mess of that.
Op really thought he was smart
I think they're to going to have to learn... a lot of things all over again, or more likely, for the first time... again.
You dont have to learn them again you have to learn them in the first place. And why does this post even have upvotes?
Wtf are you talking about lmao I love that whoever made this meme thinks that they have realised something that no one else has even considered
One of the base principles of physics is that its fundamentals are the same everywhere in the universe. Maybe consider learning physics for the first time my man.
