That the flow of time is not a constant, that the mass of an object depends on its velocity, and that the speed of light is a constant no matter what the motion of the observer ... No one—not even Einstein himself—explained these difficult, anti-intuitive concepts more clearly, or with more verve and gusto, than Richard Feynman.
This is a wonderful book which shows how a classical field theory like General Relativity can be derived from a quantum field theory. It also points out the extreme difficulty of accomplishing this in the case of gravity and ending up with a consistent, anomaly free theory.
Readers of this book will benefit from familiarity with both quantum field theory and relativity as well as a certain amount of mathematical sophistication. Don't be fooled by the similarity of title to other "Feynman Lectures on..." because this book is based on an upper level graduate physics course and assumes the background of a typical PhD student in physics.

if you had no mass! could you then be capable of speeds u cannot accomplish with a rocket?
if you could create your own gravity would it then not be healthy to have extended flights of space travel?
if you could protect yourself of the crushing gravity of a black hole would it not be worth sending a satelite into it?
if you knew how the pyramids and any other megalithic structure was built would it then not be safe to say u know the secrets of this planet aswell as the universe?
if u say no then you need to re-examine who the idiot is!

no i dont actually it was here on ats earlier this year though and i've seen it very rarely though on a few random sites
anyways what i'm saying is this! i think we could bend time and space ourselves!
time and space work off magnetism right? well thats a start in the right direction!
if we can negate gravity we should be able to bend it b/c i know damn well we can create it
all gravity really is...is inertia!
think about it why does the earth have gravity? because its rotation and the friction between it and the moon! causes the core to create a pull! our mass pushes us down along with the atomosphere and everything
so this pull and push is all inertia!
well syntrifical force is based off inertia and does the same thing it creates gravity!
so if we can do all that surely we can bend it?

lets say that there are parallel universes! and or dimensions!
our universe is amongst a sea of other universes like a plankton micronism among many!
well in order for plankton to exist they must reproduce right?
how do we know that the "big bang" and black holes are not the effects of the universe reproducing?
energy never disappears and we know that everything i worked in a cycle of recycling!
so how we do we know that a black hole isnt a wormhole to another universe thats gettin the left over energy in this one to start again in another one!
if black holes do indeed lead somewhere it is feesible to me that they are leading to another dimension or more realistically another universe!
and these black holes are actions the universe goes through to reproduce another universe!
as things are infinite so to must universes be and there has to be a way for them to exist!
getting energy from other universes to make or rerecycle the one in existence.
