21. What Happened Before The Big Bang?
Studying the universe is an incredibly fascinating and humbling thing to do, but it throws up a dizzying number of questions as well! And while astrophysics has managed to unlock a lot of the answers about our cosmos, there is one that still eludes us – what happened before the Big Bang?
Our current knowledge of physics has served us remarkably well in helping us trace the timeline of the universe as far back as a few seconds after the big bang. But the moment we try to explain what happens at or before the big bang, we are not able to do it.
All the currently known laws of physics break down at the moment. This is perhaps the oldest and the most mysterious questions in physics and doesn’t have a concrete answer as yet.
