Origin of the Universe: How did it Begin and how Will it End…

Out there, beyond what we can touch, questions about how everything started – and where it might end – tie cold numbers to deep thoughts. Right now, science says the cosmos kicked off at one point, then unfolded in ways that could lead to different endings

The Big Bang Started Everything

Some time back – about thirteen point eight billion years – a shift kicked off what we now see. Not a blast inside emptiness, instead it unfolded by stretching the very fabric holding everything.

Out of nowhere, space started as a tiny spot – packed with endless weight and fire. Right then, every rule we know about nature just stopped working.

For just a tiny split of time – about one ten-millionth of a trillionth of a trillionth of a second – the cosmos ballooned at an unimaginable pace, far beyond light-speed. Out of that burst came a more even spread of stuff and force. Smoothness followed.

Minutes passed. Temperature dropped just right so protons plus neutrons stuck together, building light cores – mostly hydrogen, some helium. Cooling did that.

Thirty-eight hundred centuries after the beginning, light began moving freely across space. Then, for the first time, photons escaped without constant scattering. That moment left behind a faint glow now called the CMB. Scientists observe it even now, long afterward. This radiation is like an echo from when atoms first formed.
