Only a collision between super massive materials could produce such huge larger energy as we see in Big Bang.



Like a cyclical interaction with a neighbor brane which is essentially another universe? Because that's the ekpyrotic universe model. And it fits with your imagination.


What is "ekpyrotic" ? Google Translate can't translate it, sorry.


The first hit from DuckDuckGo for 'ekpyrotic' is the Wikipedia page https://en.wikipedia.org/wiki/Ekpyrotic_universe . It describes the reason Steinhardt created that word as the name for the model.

The Steinhardt and Turok preprint is at https://arxiv.org/abs/hep-th/0111030 , published in the journal Science at http://science.sciencemag.org/content/296/5572/1436.full .

> We propose a cosmological model in which the universe undergoes an endless sequence of cosmic epochs each beginning with a ‘bang’ and ending in a ‘crunch.’ The temperature and density are finite at each transition from crunch to bang. Instead of having an inflationary epoch, each cycle includes a period of slow accelerated expansion (as recently observed) followed by slow contraction. The combination produces the homogeneity, flatness, density fluctuations and energy needed to begin the next cycle.
