Well thanks.

ok but taking in account that observation , that if you are in motion things go faster. Light is faster than what we measure?

I said IMAGINE , it is impossible of course. Then , don't just say nonsense , explain why. Make your point of time dilation. I thought that if something was on motion time was faster than if it wasn't . I read about it and einstein discovered it.

How can you make something move forward or backwards with magnets. I didn't got it in here : Minute : 5:00 forward It said how the train move but i don't understand why it moves. It makes no sense for me because it is the same force that keeps the train floating?

Technically , C travels faster than itself because of this principle : If you are moving , time is faster. If you are not moving , time is slower. It was something Einstein said once. Now , imagine you are on something that travels at C with a chronometer. C will seem to travel faster if you...

and why space does not exist then?

another question . There is something moving when the universe expand , space and time because without the universe there is no space and time out of it so we can't go out of it because there is nothing , nor space nor time to travel but but when the universe is expanding at 3c+ we have new...

i am doing a proyect of this but i don't understand something. Why does the expansion of the universe is not motion and light is? In both nothing is moving , is there?

It is an internal maths fair in our school . We are at 9th grade.

Homework Statement Which problem do you recommend us to talk in a science fair? Homework Equations no The Attempt at a Solution We have thought about paradoxes but our teacher told us that each person has a different point of view of something like the grand hotel paradox and we need to do...

So , another question , the universe is expanding from everywhere? or just from the edges?

If space is not matter , then what is it? How should i imagine the limits of space? What limits the space ? A wall? Nothing? If nothing limits the space , how can it have a limit if the limit is nothing ?

Well , if he didn't took that in consideration , why can't dark matter or energy travel faster than c? I know that is the rule einstein once said but why? i have not read the relativity theory yet and i know that c is that fast because it has 0 mass , but how did he knew that , that was the...

Also , we know almost nothing of dark energy ( i think) what if dark matter and energy can travel faster than C? did Einstein knew of this in his relativity theory?

wait , i am not sure of what i am going to write but , galaxies are going apart from each other faster every time right? so you say that they receed at 3c which means that they are moving at 3c further away?
