Episode-II Vs Spider-man

Uh-oh. Ush has competition from Arsey.

He wasn't wrong in the sense of stupid, though.

Every rule in physics only applies when there is a beholder. For example, they say nothing moves faster than the speed of light. B***ocks. If I were in space (where there is nothing to relate distance to) and I were travelling at the speed of light. I then passed some other space traveller who was going a mere 10km per hour. It would appear (to both of us) that we were travelling the speed of light+10kph.

NO IT WOULD NOT!

Relativity states that you cannot exceed the speed of light from ANY point of view. It does not matter what your combined speeds are; from where you are you will NEVER see anything exceed light speed. It cannot be done (excepting some new hyperadvanced theories on the correct way up of the Universe). This can lead to different observers seeing different things, according to where they are and what speed everything else is moving at relative to them.

What you have said is so, SO wrong...

And in space you have no more or less point of reference for your speed than you would on Earth. In the end, the only important point of reference is yourself (though general speeds are measured relative to Earth).

To give some examples:

Light always moves at lightspeed, regardless of what you are doing. If you were on a bike and trying to race a car,logic dictates that the faster you pedal, the less quickly the car would get away from you. Light does NOT work like this. No matter how fast or slow you pedal- or even if you stay still- the light beam would get away from you at the same speed- light speed- as far as you are concerned. Even if you went to light speed (relative to an observer... and it would be impossible anyway), the light beam would still get away from you at light speed, as far as you saw it.

Now, it would seem logical that the observer, therefore, would see you moving at light speed and the light beam moving at TWICE light speed, because that is how it is moving according to the biker. But he wouldn't, because light speed at the limit. HE would see biker and light beam moving at thr same speed- light speed. This even means that the biker would see things illuminated that the observer wouldn't.

Relativity contradicts common sense- two observers can see the same effect differently. But light speed will NEVER be exceeded, from any point of view.

The reason that this happens is to do with time, but it gets too complex at that point.

Well I thought I was being a smart @#%$ but apparently not. I'l just curl up and die now.

Thanks Ush

No problem. You should see how my friends have yelled at me over time...

However, your basic point, that physics is all on observation, is very true and was a good point to make.

*stands there with his mouth open... baffeled* 😂

It all makes sense, I promise. That's just basic relativity. I decided not to read any further than that...

Hmmph. Quiter! 😂

There's a lot of THAT about. 😂

I'm impressed, Ush.

Physics boggles the mind. That stuff is real basic, as far as relativity goes.

I know. And yet... to post it like that, off the top of your head. Not bad.

I agree..(apparently no one can tell when I make a joke 🙄 )
