“…It is 12 orders of magnitude smaller than the strain sensibility of LIGO's interferometer, which can probe amplitudes up to ∼ 10 −22 in the frequency range from 10 Hz to 10 kHz. Although it seems hopeless to reach such small distances, the Chongqing University detector (currently under development) will be able to probe amplitudes as small as 10 −32 [Baker, 2009] in the high-frequency range 0.1-10 GHz, which is not far from the bound just found. Observe, however, that we have found an upper bound on and not a lower one, thus could be arbitrarily small and not be detectable by the Chongqing detector.…”

Effective field theory techniques are used to study the leading order quantum corrections to the gravitational wave backreaction. The effective stress-energy tensor is calculated and it is shown that it has a non-vanishing trace that contributes to the cosmological constant. By comparing the result obtained with LIGO's data, the first bound on the amplitude of the massive mode is found: < 1.4×10 −33 .

“…At the very beginning fraction of a second, there was an infinite force of infinite Shrunk space, we speculate that the infinite force of Shrunk space gave rise to the Big Bang, and caused the rapid growth of space. That process would appear to move very rapidly in the early universe, and was only readily observable by detectors of high-frequency gravitational waves such as the Li-Baker [14][15][16]. After the beginning of the universe, the Shrunk space continues to expand, but in the distant past, the pressure of the shrunk space, and density should have been greater, so the universe must have been expanding more slowly than it is today.…”

The cyclic universe theory is a model of cosmic evolution according to which the universe undergoes endless cycles of expansion and cooling, each beginning with a big bang and ending in a big crunch. In this paper, the researcher finds a unique property of Space-time, this particular and marvelous nature of space shows us that space can shrink, expand, and stretch. This property of space is caused the size of the Universe changing over time: growing or shrinking. The observed accelerated expansion, which relates the stretching of Shrunk space for the new theory, is derived. This model is based on three underlying notions: First, the Big Bang was not the beginning of Space-time, but rather at the very beginning fraction of a second there was an infinite force of infinite Shrunk space in the cosmic singularity, that force gave rise to the big bang and caused the rapidly growing of space-time, and all other forms of energy are transformed into matter and radiation and a new period of expansion and cooling begins. Second, there was a previous phase leading up to it, with multiple cycles of contraction and expansion that repeat indefinitely. Third, the two principal long-range forces are the gravitational force and the repulsive force generated by shrunk space. They are the two most fundamental quantities in the universe that govern cosmic evolution. They may provide the clockwork mechanism that operates our eternal cyclic universe. The space will not continue to expand forever, no need however, for dark energy and dark matter. This model of Space-time and its unique properties enables us to describe a sequence of events from the Big Bang to the Big Crunch.
