The beginnings of the universe have always been a source of wonder, controversy, and mystery. Although the Big Bang is the generally accepted origin of all we know, physicist Brian Cox has proposed something even more fantastical: something existed prior to the Big Bang—and it could be frightening.
What Precoded the Big Bang?
Historically, the Big Bang is the time when space and time began to exist. Prior to it, there was allegedly nothing—no energy, no matter, not even time itself. Some hypotheses contradict this notion, proposing that our universe is merely one of countless others in a never-ending string of cosmic occurrences. Cox, who is particularly good at describing complicated physics in a way that will engage you, has hinted at something that is both deep and scary: that the universe had a precursor, and it could have ended in a manner that is hard for us to fully understand.
The Terrifying Implications
One of the most intriguing concepts in contemporary cosmology is that our universe is part of an endless cycle—where one universe collapses, giving rise to another. This is called the cyclic or conformal cyclic cosmology (CCC) model, advocated by physicists such as Sir Roger Penrose. If it is true, then it implies that there was another universe before ours, and it could have ended in a manner that influenced our own existence.
But why is this notion frightening? Because if universes end and are reborn in cycles, it implies that destruction on an unimaginable scale is a natural part of the universe. The heat death of the universe, a theory that one day everything will become cold and dead, may just be a reboot stage before a new cosmos takes its place. If Cox and other physicists are right, our own universe could eventually suffer the same destiny.
Echoes from a Past Universe
Cox and his colleagues consider the notion that remnants of an earlier universe would persist in our heavens' background radiation—the diffuse glow that remains from the Big Bang. Others think that exotic features in the radiation might be "ghosts" of black holes or other objects from before the existence of our universe. If this is so, it would indicate that former universes leave their imprints on the fabric of space and time themselves.
Conclusion
Brian Cox's theories compel us to face an humble reality: our universe could not be the first, or the last. If there was something prior to the Big Bang, it threatens our comprehension of existence and of time itself. Whether the universe is within an infinite loop or something even more bizarre, we seek answers—and with them, the knowledge that the secrets of the universe might be much farther out of reach than we could possibly envision.

even if it was terrifying?
