When you walk forward in a train, you are faster than the train. amirite?

Up until the speed of light, then for some inexplicable reason you cant go any faster...

Inb4 relativity

Unless it's travelling at the speed of light

@88080808088 Unless it's travelling at the speed of light

how would this happen? lets say you are in a train that is going at the speed of light in space and you run forward through the carriages, wouldn't you technically be going quicker than the speed of light?

i think im missing something here...

@KilljoyX how would this happen? lets say you are in a train that is going at the speed of light in space and you run forward...

Nothing can accelerate faster than the speed of light in a vacuum. The train in a vacuum is an inertial reference frame which is the same as all other reference frames. As such, walking in the train feels the same as any other train on earth. You are faster than the train relative to the train and only the train. However, you cannot be faster than the speed of light, so what occurs is time dilates and the length of the train contracts to outside observers to account for the difference of speed inside the train. Very simplified and probably inaccurate at some parts, but this is the gist of it

@KilljoyX how would this happen? lets say you are in a train that is going at the speed of light in space and you run forward...

It's hard to explain but time and distance slow down and contract as speed increases. The effect is amplified the closer you get to the speed of light so you can never go faster than it.

Most likely something couldn't be built to help you exert enough force to take a step. I imagine hitting the cosmic speed limit is like hitting a lead wall. You'd only be accelerating (relative to you) a small bit maybe to 99.999% (if you're lucky) so you'd be pushing against that wall lightly.

Or unless you're traveling at the speed of light

Einstein told that long ago !

Relative to earth

what if the earths rotation in the opposite direction is faster than the train … then you're slower

@Framie1 Ok, listen, I need a optimzed way of cumming. Suggestions?

Finish into the direction of an easterly wind, preferably into one of the jet streams. Either that, or let elon hitch you a ride up to space and let gravity do the rest.

When you walk towards the west you are faster than the earth

When you walk forward on the said train and turn on a flash light... the light is still only going speed of light.. the speed of the train and you walking does not get added.

The train plus you are faster than the train... you are not faster than the train even in the given situation to be accurate.

If the train was traveling at the speed of light…

Relatively.

You're not faster than the train, but you are moving faster than the train.

@Surfaces You're not faster than the train, but you are moving faster than the train.

That is generally assumed when saying that one thing is faster than another in a context like this.

Running backwards while the train is going forwards will result in you running on the world's biggest treadmill

OP studied physics👍🏻

Almost like speed is relative. Or something.

Unless you're walking in some direction other than the direction of motion, in which case you're slower than the train

So i could easily walk across country on a train

If in moving I think the ultimate speed being travelled by yourself is only possible because you are in the moving train, so essentially you have at that point become a person-train hybrid thing...

I wonder if they can use this to get to light speed... like if you and your train where put on another train... and then keep stacking it...

What if you move forward to the back of the train

when you walk in light, you are flash?

No, you're just catching up to the front of the front carriage.

When you walk forward in a lightspeed ship, you are faster--

(Albert Einstein has entered the chat)

Depends on the point of view!

@jodzdzownica Depends on the point of view!

They call em ‘reference frames'

@jodzdzownica Depends on the point of view!

from my point of view the Jedi are running!

From every perspective you're still faster than the train

@Hatchadi From every perspective you're still faster than the train

Not from the perspective of someone moving in the same direction as you but faster than the train (say, in a very speedy vehicle or an aircraft). In his perspective, the train is moving away from him along with you, but you are moving away at a slower speed.

@Hatchadi From every perspective you're still faster than the train

Not if you look at it from the other side. Then, the train goes at let's say 1 speed and you, working in the other direction, go a little slower.

@Legendnoel77 Not if you look at it from the other side. Then, the train goes at let's say 1 speed and you, working in the other...

But you will still be faster than the train. The only way Is if the observer is going more than half of persons speed in comparison to the train. Only then wil the train seem faster.

@Achilles982 But you will still be faster than the train. The only way Is if the observer is going more than half of persons...

Hmm. Now my mind doesn't know what to think anymore ^ thanks for blowing my mind. I'll need an hour of extra sleep to get this outta my system tonight ;).

@Hatchadi From every perspective you're still faster than the train

Not if you look at it from the perspective of moving through space. If the train is travelling away from Earth's movement in space, then you walk forward, you are travelling through space slower than the train.

@Hatchadi From every perspective you're still faster than the train

from the perspective of the origin point of the singularity, if the train is traveling in a direction towards the singularity (thus making its relative velocity lower than the earth) walking "forward" on a train would compound this problem, and therefore make you slower.

Relative to the ground yeah, but from your perspective the train is stationary.

With the same logic, walking East makes you faster than the earth.

@sharmaji1301 Relative to the ground yeah, but from your perspective the train is stationary. With the same logic, walking East...

Relative to the earth's orbit only, the entire solar system is also orbiting around the centre of the Milky way, which is also flying around in space

@Shiny244 So then we wait until the aphelion and run as fast as we can at night

I have no idea what you're talking about and i doubt you do either but i like it

@88080808088 I have no idea what you're talking about and i doubt you do either but i like it

Haha well it does sound kinda like witchcraft I guess. The aphelion is when the earth is furthest from the sun, and when it's night the earth is facing away from the sun, so it's the maximum tangent to the circumference of our orbit to the sun to be running with the direction of the rotation of the planet.

Good god. 😭

From your point of view the train is the one that's moving.

When a train is travelling down the track, there is always part of the wheels moving backwards.

Faster mabye but never further then the train

Your calculations forget about the rotation of the Earth.

Not true if you walk off of it

Walk west and feel the power

If you shine a flashlight forward on a moving train, those photons are not moving faster than the ones coming from a stationary flashlight pointed them same direction outside the train.

Umm yes relatively.

theoretically… if you had a train in a train the train inside will move twice as fast, so if you keep doing it you can go the speed of light, right?

when you walk forward on the earth, you are faster than the earth.

Cue the flat earther argument of no relative velocity…

If the train is stationary then any direction will do.

Unless you walk forwards against the direction of the train's travel.

Trains are immobile, it's the earth beneath it that moves
