Light Speed and greater

just an interesting Discussion at our Forum

when 2 Space Travel are gone with 1 x Light speed in different Directions , they are going endlessnes
then they are going about 600000km/s

but it is said that nothing is faster than Light Speed, but the Room between the 2 Space Travel is going to 2 x Light Speed.

an interesting Discussion.

something about light Speed

I bet it is. As things are now the speed of electricity is the limiting factor . How can you see where you are going when your sensors (or whatever) run at slower than light speeds? Light speed is not possible why dwell upon it?
 
Using that same logic

If two travelers were at light speed, going the same direction, then they really aren't moving since they aren't getting farther apart.

Drop it down to 60 mph or 90 kph, and it still works the same. Distance and speed aren't the same thing.
 
To be perfectly honest, I can't get a clear picture in my mind of exactly what you are talking about. However, it sounds to me as if you are trying to apply a classical application as disproof of a relativistic phenomena, which isn't practical. Classical mechanics allows you to achieve any speed you wish above light speed, and doesn't depend on the frame of reference.

Edit: Just because its bugging me, what is it exactly that is traveling at 2x ls?
 
According to Einstein if you projected something (a beam of light for instance) out the front of your spaceship as you were travelling at the speed of light the speed of that light beam would still only be the speed of light, not the speed of your craft plus the speed of light.
According to theory as any matter approaches the speed of light the physics for that matter change, however it may be possible that this is a relativistic effect, as the matter would seem to be changing according to outside observation but in fact from it's own frame of reference is merely continuing to accelerate. As we can not test this it is all a matter of conjecture & hypothesis for now.
Theoretically as matter approaches the speed of light it will take on the aspects of energy, it will tend towards infinite density and time will not pass for it in the same way that time passes for the observer.
Who really knows though? Currently there is no way to test, it would be nice if there was eh?

on the physics changing, if memory serves me right mass is reduced to 0 at 1C which is why einstien said it is impossible for matter to reach any mulitple of 1C or higher. That always bugged me too, as mass is constant, unless you convert it to energy.
 
I believe it would appear your mass was changing to energy the closer to 1C you go - that is relative to someone observing you who is "relative to your speed" standing still. 😉

It's all about 'who is the observer' and 'who is the one in motion'.

It could be thought that the one "not moving" (the observer) is really moving away from you at an increasing rate of speed as you accelerate at 1 G for a sufficient period of time to exceed the speed of light.

Really, what's to stop you from acceleration except running out of fuel.
To your own point of view you are merely accelerating at a rate of 1G for a very long time, giving you a nice sense of gravity while travelling.


It's all about point of view IMHO. 😉

Roger that! :Q 😕

Some of us are still trying to figure out the relatively mundane stuff, like why we drive on parkways and park on driveways?

the speed of your exhaust would stop you, if the speed of your exhaust is only half the speed of light, you would not accelerate beyond that speed, as your exhaust would no longer be pushing you
