The birth of the Universe

The birth of our universe remains one of the deepest mysteries in science. According to Stephen Hawking, before the Big Bang, there was no “before.” Time itself began with that cosmic explosion; marking the start of everything we know. In his view, asking what came before is like asking what’s north of the North Pole.

Michio Kaku offers a different vision. He imagines a multiverse; countless parallel worlds floating like bubbles in a cosmic sea. Our universe, he suggests, may have emerged from the collision of two such worlds, sparking the Big Bang and shaping space-time.

Roger Penrose believes in a cyclic universe. In his theory, our cosmos is just one chapter in an eternal story; each Big Bang followed by expansion, decay, and rebirth. The universe, like a phoenix, rises again and again.

Despite these brilliant ideas, our knowledge is limited. The singularity at the heart of the Big Bang defies our understanding. Infinite density, quantum uncertainty, and observational limits leave us with more questions than answers.

Even among the greatest minds, the beginning of the universe remains a realm of elegant speculation; a reminder that mystery is the heartbeat of discovery.
