What is 'Pulsating theory' and 'Steady state theory'?

Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.

What is the no boundry universe theory?

A "no boundary" universe is a universe where the change in energy is positive or negative everywhere in the universe. Such a universe theory calls for everywhere expansion or everywhere contraction. The current central dogma in Astronomy is for such an expanding universe. The corrected Law of Gravity indicates that the universe is bounded and not expanding.
