観測結果の問題から、ビッグバウンス理論も支持を集めている―この理論だって数十年後に消えている可能性もある

"Black hole at the dawn of time challenges our understanding of how the universe was formed".

It had reached its size just 690 million years after the point beyond which there is nothing. The most dominant
scientific theory of recent years describes that point as the Big Bang — a spontaneous eruption of reality as we
know it out of a quantum singularity. But another idea has recently been gaining weight: that the universe goes
through periodic expansions and contractions — resulting in a “Big Bounce”. And the existence of early black holes
has been predicted to be a key telltale as to whether or not the idea may be valid. This one is very big. To get to
its size — 800 million times more mass than our Sun — it must have swallowed a lot of stuff.

As far as we understand it, the universe simply wasn’t old enough at that time to generate such a monster.
一つ言えることは特異点のことをより詳しく知るだけでなく、ブラックホールの観測情報をより多く集める必要があるということだ
