A moment-before time existed

There was a 'point'- a singularity

Massive energy burst- 'from where'??

The Universe started (15 million years ago) to expand at an incredible rate in a 'very short' amount of time. Time began here, as we know it.

Matter + Anti matter interacted in a fog of radiation

Quarks produced (particles that make up protons and neutrons)
