Описание: Light is supposed to be the fastest thing in the universe.
Nothing moves quicker — at least, that’s what we used to think.

But scientists have discovered how to slow light down…
and even bring it to a complete stop.

Inside a special type of ultra-cold gas, just a few billionths of a degree above absolute zero, photons lose their speed.
They interact with the frozen atoms so strongly that they literally pause — frozen in place, suspended in time.

When the atoms warm up again, the light continues — as if it never stopped.

That means information, in the form of light, can be stored and released later —
like pressing pause and play on the universe itself.

Reality has a stop button.
We just found it.
