Thank you all for the wonderful explanations.

Thanks. By the way, what is Born Rigidity? I heard it is considered so that the distance between the ceiling and the floor remain constant. Is it considered to keep up with Lorentz Contraction, which may change the distance between the two?

I read from a physics website that says that an accelerating object experiences different acceleration throughout its structure according to special relativity. I never thought of that! "In special relativity, one finds that when a spacecraft maintains its structural integrity, so that the...

According to an outside observer, an object slows down as it approaches the event horizon but never reaches it. Why does it slow down? Thanks.

Well, I found this question in the http://en.wikipedia.org/wiki/Acceleration" topic in Wikipedia, and I was confused about its meaning. Thanks.

In terms of general relativity, what does this question mean? Thanks.

So weight is basically the proper acceleration we experience at surface, according to General Relativity?If so, how does our proper acceleration differ at different points of the Earth? Thanks.

Thanks. But what about, Is it because the space-time curvature (gravitation) decreases slightly by distance?

How does http://en.wikipedia.org/wiki/Weight" work in general relativity? Well, since GR states that the gravitational force does not exist... What about different weights at different altitudes?

Which coordinates will give me the answer yes?Thanks much.

I see many different answers. So, which is it? EDIT: Oh, the "acceleration" in my bold part is coordinate acceleration. Objects traveling along geodesics in curved space-time don't experience proper acceleration.

Thanks for the clarification, guys.

What do you mean by that? Thanks.

So is the falling (inertial) object traveling at constant velocity or stationary as we accelerate towards it?

So which one is more correct? Or are they both correct? I'm confused.
