Thanks for the reference. There was some interesting discussion. So technically nothing actually goes inside a black hole it is all frozen in time outside the black hole. Duordi

How can space know how to curve from a black hole. My understanding is that the no information can escape a black hole so how can space know how much to curve? Duordi

Ok I got it.

Yes the whole universe will contract but the ship will un-contract because we are moving the same velocity. I think.

Thanks for the reference Granpa It is weird how the light focuses in the direction of motion. JesseM you lost me. The two ships are 1 foot and 10 light years away from me and traveling 95% of light velosity away from me. Now I accelerate to 95% light speed toward them. Our velocities...

So there is a lot of distortion and delay due to light travel. Forget the camera, bad idea. Suppose a distant star was traveling 99% the speed of light away from me and it slowed down to 90% the speed of light. Eventually when the light reached me the lorentz contraction would decrease and...

If I am the one who accelerated then the ship would appear to be closer just after the acceleration? If I took a camera and accelerated it to 99% the speed of light and took a picture at stars and then had it send the information to me I would get a photo of distant stars that look very...

If I am watching spherical mass A that is traveling away from me at close to light speeds it lorenz contracts like I am looking down at a plate. Does the distance mass A is from me contract also or does it stay the same distance away ?

Wow, that clears a lot up thanks for the reference!

I can only tell you my limited understanding of it. If you pushed a pea and it approached the speed of light it would increase in mass until it was an equivalent mass of the sun and the faster it went the more energy it would take to accelerate it. You would never be able to accelerate the...

This is how I understand a charge field changes with motion. A charged particle, if it is accelerated to a velocity close to the speed of light, will flatten in the direction of motion and its charge field will also. The field will strengthen perpendicular to the velocity vector and weaken...

The reason I was interested in relativistic mass is simple. I was trying to determine if distant galaxies which are receding from us at a high velocity have a relativistic mass component causing an increase in the gravitational force they have on us. GR does not have force equations only...

I read the material and it all makes sense but it occurred to me you could explain the test charge response and the charges in the wire by replacing the Lorenz contraction with change in field charge magnitude due to a relativistic effects of a “charge in motion” principle. That is to say...

Shoot! every time I think I am starting to understand this stuff it throws me a curve. Does a field of a charged particle in motion have a Lorenz contraction?

If object A travels close to light speed of light with respect to object B then object A will seem to have an increased mass as observed by B. If A is also a charged particle will the charge strength be increased also or will it remain at its rest velocity field strength as determined by B?
