Universe May Have Had a Pre-Big Bang 'Secret Life'
The universe may have experienced a contraction phase before the Big Bang, forming small black holes that could be the source of dark matter. This 'bouncing' cosmology theory, if validated, could change our understanding of the universe. Future observations from gravitational wave observatories could provide crucial evidence.
A recent study published in the Journal of Cosmology and Astroparticle Physics reveals that the universe may have experienced a contraction phase before the Big Bang.
This 'bouncing' cosmology theory suggests that black holes formed during this phase could be the source of dark matter.
If proven true, this theory could reshape our understanding of black holes and dark matter, which comprises about 80% of the universe's matter.
During the contraction phase, density fluctuations might have created small primordial black holes that survived into the current expansion phase.
These black holes, potentially formed from the early universe and not decayed due to Hawking radiation, might explain the elusive nature of dark matter.
Future gravitational wave observatories like LISA and the Einstein Telescope could provide crucial evidence to support this theory.
Although still in its early stages, the research opens up new possibilities about the universe's origins.
