NOW WE KNOW HOW SPACE-TIME IS CURVED!

Accordingto Einstein’s general theory of relativity (GTR),our universe was built with four-dimension space-time but it is impossible to visualize how the curve space-time is! As Richard P. Feynman word “We live in three-dimension space and we are going to consider the idea that three-dimension space is curved ……, we can’t imagine space being bent in any direction because our imagination isn’t good enough ….”. Or according to Stephen W. Hawking word “It is impossible to imagine a four dimensional space.”

Also based on GTR, our universe is what was called “hypersurface of hypheresphere”.
Again there is no one that could understand or visualize it either! What was wrong with GTR? Of course we knew that the theory should not be wrong because we have learned that it have passed several well known tests such as the bending of light ray while passing near the sun. So there must be something in the theory that is missing; something that leads to wrong interpretation!

The obvious clue of the wrong interpretation is the nature of vacuum space in GTR, which is assumed tobe empty space. It is Einstein’s genius that he could imagine (guided byMach’s principle and the principle of equivalence)how to link an energy-momentum tensor to describe the curvature of the emptyspace-time! But it comes with a problem followed; that is how “nothing” could be curved. When you say “a surface is curved”, it means “surface of something is curved” such as a surface sheet (two-dimension curved surface), which is no problem. But we could not get the same thing with three-dimension curve space from nothing! So, the best thing we can do is just using method of analogy, and this leads to the mentioned problem above.

Based on the concept of the existing of “something” that is the “dark matter” in which all cosmologists are still searching. (And actually it is “vacuum medium energy” which is the fabric structure of space-time instead of the believed “empty space-time”.) Now, then it is easy to see how the space is curved. And we would found that the curvature of “vacuum medium space-time” is the “space-time with non-uniform density of vacuum medium energy”! Detail with simple explanation in scientific way was shown in “Completed Einstein general theory of relativity (CGTR)”, which is presenting in www.vacuum-mechanics.com.

Also inCGTR, we will show how much the existing vacuum medium energy (dark matter) is! We will understand the mechanism of gravity; why and how masses attract each other! And we will found that actually hypheresphere” is an ordinary sphere.Finally we would found that CGTR could pave the way to the theory of everything!
