The State Before the Big Bang

Many hypotheses about the state before the Big Bang have been proposed.
Currently, research is being conducted to determine the state before the Big Bang through extensive calculations, including the application of numerical relativity.

With advances in science and technology, about 10 years ago, there was an opportunity to discover traces of the state before the Big Bang. However, this would require a huge global joint investment, and scientists from NASA and other countries have said, "It's ultimately a matter of money."
In the end, Earthlings, obsessed with funding for war, were unable to secure sufficient funding for space exploration.
Currently, several spacecraft, including Webb, are exploring the period immediately after the Big Bang.
However, as the universe expands day by day, observations going back to the year of the Big Bang become increasingly difficult.
Furthermore, since the universe was opaque and unable to transmit light immediately after the Big Bang, actual observation would be difficult for a number of reasons.
The university where Harada previously worked included PhDs in cosmology and physics.
When Harada was having lunch with them, they said,
"Direct observation is difficult, but we might be able to find some kind of trace."
If even one trace (relic) were to be discovered, it would be possible to make a great leap forward in our understanding.
The question of what the universe was like before the Big Bang is fundamental to the reason for our existence, and is also an important question that relates to all thought, philosophy, and life.
