Someone posted this to my question on QUORA.
Einstein's theory of relativity can be explained through the interactions of gravitational wave theory. Time dilation and length contraction can both be interpreted as results of the expansion and contraction of gravitational waves. When an object is moving at near light speed, it must be producing a huge amount of gravitational waves. An observer looking at the speeding object will see a distorted image caused by the expansion or contraction of gravitational waves.
Time slows down or decreases because the distance is increased by the gravitational wave during the expansionary period. Length contraction is explained by the shortening of space-time during the contractionary period of the gravitational wave. The trough of the wave is located at the actual moving object itself while the crest is just in front of the object. However, once the gravitational wave finally hits the border of the universe, it will just permanently expand the space-time and therefore the universe.
When the formation of gravitational waves start dissipating due to the lack of gravitational interactions, the universe will collapse on itself and restart the cycle of the Big Bang. However, gravitational waves will only stop being generated when all the matter in the universe combines into a super dense object/nucleus or SDN. Therefore, the maximum lifetime of a universe can be determined by how long until all the mass in it forms into one nucleus.
Can someone read this (its very short) and the part where he concludes the universe will end in a big cruncch and tell me if its valid?
