I meant "one plank-length".NOT 1km.

We'll never see her crossing the event horizon,but she will see our Sun turning to a white dwarf.That means no sungularity and more:most of the mass needed to form a BH is accreted beyond the event horizon,might be a plank-length above.That's why BH gravitation still works,if it's propagating...

If we have an infalling observer through the event horizon,will she see the end of the Universe?

Sorry,I thought I was talking to a layman.English is not my native.

[Moderator's note: edited to fix quote tags.] The tidal forces are not important,just the acceleration,that one of the clocks expiriences.It accelerates to near the speed of light,than returns back to the one,that has not been moved.In SR there are two inertial frames,passing by each other and...

Flat Spacetime does not mean "inertial frame of reference",which is the initial frame of Special Relativity.

I was just trying to say,that the twin paradox has nothig to do with the Special Relativity.The principle of equivalence(no tidal forces)is implied here.

We have two synchronized clocks and one of them is acceleratated near the speed of light.The GR approach is neaded here,because SR is symmetric by the Lorenz Transforms.

I'm thinking about the kinematics only.

Let's change the velocity of 1-metre measuring-rod from 0.9c to 0.9999c for one nano-second.What kind of a contraction shall we observe from our stationary system?

Are You saying that,if an object is accelerated,it doesn't seem to be contracted?

Maybe the contraction would not be faster than light because of the time dilation?

Lorentz contraction also doesn't describe the reduction in length of an accelerated object. So,describe it.

O.K.It'snot about Lorentz contraction,but the contraction near the speed of light with acceleration.
