I have few questions to ask for the members of Brilliant :

Finn, I have 2 questions to ask on your article :
1. What do you mean when you say that " pulling is what time is " in 17th line ?
2. What do you say about " Length Contraction " which is very difficult to understand ?

I'm saying that in the model I'm using, where spacetime is a latex-like fabric, that where a warping is the space, the pulling of the fabric is like a representation of time. As for length contraction, you're right, it's more complicated. A quick Google search should help you out, though. :D
Finn, I will surely say that you would become the youngest scientist of USA !!!
:D I wish. :D
Those are good questions! Read this article I wrote a while back. It's a bit long, so I'll just answer your questions here:
Space-time is the fabric that everything is made of, including empty space/void. It has been observed that large bodies of gravity can even have an effect upon space-time, which you have called "curvature of space-time". The article should help you become familiar with the mechanics.
Einstein's theories of relativity talk about relative motion, like two cars driving next to each other, or somebody bouncing a rubber ball in a plane. He "dumb"-ed it down a lot so that almost anybody can read his paper.
Thank you for your answer, Finn. I asked these questions so that i could understand Stephen Hawking 's " Black holes and Baby Universes and other essays " clearly . I hope I would still ask more questions on astrophysics and the universe within this month
Space time refers to the dimensions of the universe.
Not really. It really means the very fabric of existence, not just space but also time.
Thanks Finn Hulse for a great explanation. ...hope you will help me clearing my doubts
You're welcome! :D
