All the information is very useful too me as I want to understand all the theories related to gravity and how those theories relate to one another.
If I have understood correctly string theory is the theory that has a graviton in it and thus far there is little or no evidence to support...
I just realized I probably should have put that part about Einstein's general relativity in my other thread. Only two threads and I'm already getting them confused. I'm going to spend some time thinking about how I would feel if gravity were to pull on me from every direction at the same time...
This is very helpful to me understanding the push of the Earth from me standing/walking on it. Another thing to look at is a sponge which has much less of a push than the Earth and so it gives more and compresses more than the Earth would but at a certain point the sponge does not compress more...
I very much appreciate all of you for your patience with me and for helping me understand even though I am not approaching things the way many of you have/do. Or did some of you also start out asking questions before bothering with the math? Do you mean that I must get into the mathematics to be...
I'm guessing GR stands for general relativity and I do believe I am understanding small portions of it. I'm sure my questions make it quite obvious that I am no where near the level of understanding of Einstein.
Does both Newton's theory and Einsteins theory include the premise that the Earth...
I'm going to have to spend more time looking at this potential you speak of. I've read the first paragraph of few times and everything else in the link at least once and I don't see how it relates and am not understanding it right now. It seems there is a difference between potential theory and...
I'll need to learn more about quantum teleportation. Thanks for the link. I listen to a lot of documentaries and lectures on you tube because I can do that while working.
Are there any textbooks online?
It is true that I feel understanding gravity will help me with my book but since the...
I've read Newton's Shell Theorem on Wikipedia, twice. Of course that was only the first part which explains it pretty well. It isn't going to do me any good to get into the math yet, but I did recognize some of the notation from calculus.
What is puzzling is that if all mass no matter its...
I guessed that the size of the object would be smaller than Earth to have the same mass but hadn't thought that because you would be closer to the center the gravity would be stronger.
So to keep the gravity the same even though the material is different then in the case of this example the...
Ah but if I remember correctly from a documentary I listened to, at the quantum level they believe they can do teleportation. If that can be done at a larger scale then mass could be teleported elsewhere temporarily, thus shutting off gravity because of the reduced mass and then teleported back...
I just read a thread here about artificial gravity and depending on how I decide to do things this knowledge could help me make a different kind of artificial gravity. However, my initial reason for trying to understand it was so that I can have a feasible way for a large object to shut off its...
According to the theories that discuss gravity, if humans were to create a solid metal sphere with the same mass as Earth would it have the same gravity as earth?
Would it have to be orbiting something and/or moving to have that same gravity? Or could it be stationary and have the same...
A driving force for my interest in gravity is to better understand it so that a science fiction book I am writing may be more realistic. That is at least what sparked my interest but there seems to be more to it than that at this point and so I keep reading and listening to documentaries and...
Now I feel dumb not realizing that BB was for the big bang. Thanks for giving me the meaning!
I am actually curious to see what aspects of physics is found in the scriptures and how much is similar and how much is different. I don't remember reading anything about gravity in the scriptures...
Thanks! You're answers help me to understand better as to how both could be in use when I was thinking it should be one or the other.
What level of calculus would I need to understand the formula's you posted. I know I took the first year of calculus but don't remember mention of its use in...
