The Horizon Problem | The Universe's Biggest Mystery
Ever wondered how the Universe looks roughly the same in all directions? Because, technically, it shouldn't. It doesn't make sense.
So does that mean we're missing something in our physics? Something like inflation?
Or is the universe cyclical, going through Big Bangs and Big Crunches?
Or does the speed of light vary with time?
