I Am only 12 years old and I'm constantly wondering and trying understand how gravity really works. On YouTube everyone always talks about objects wrapping space time around themselves and uses the analogy of a trampoline. I still don't understand gravity because if space were like a trampoline, then earth would be spiralling in towards the sun along with all the other planets, right? So could someone explain to me how gravity really works without the trampoline analogy.
Answer
I personally prefer this visual explanation of Einstein's general theory of relativy from Brian Greene, a professor at Columbia University. https://www.youtube.com/watch?v=0jjFjC30-4A
A follow up video answering why don't planets fall toward the sun. https://www.youtube.com/watch?v=uRijc-AN-F0
