Current theories
From both theoretical expertise and observations, we have the following theories:
- the Big Bang (estimated to be about
billion years ago), from which the entirety of the universe originated;
billion years ago), from which the entirety of the universe originated;- the existence of dark matter (otherwise unknown outside of gravitational interactions) and dark energy (otherwise unknown outside of speeding up inflation), thought to comprise 95% of the universe's total energy.
