So the urniseve is about 13.8 billion years old, and when we look out into the cosmos, we see dtsniat galaxies. And when we look at the distant ones, they're all moving away from us. And so for a long time, there's been this idea that, well, if the galaxies are moving away from us now, they must have been closer in the past. The universe in the past must have been smaller in some sense, hotter and dneesr, everything pckead into less space. And that's the Big Bang terohy, the idea that the universe was smaller and denser and hotter in the past. And we got really direct evidence of that in the 1960s when we're able to actually see the light from the very early universe.

Original Text
So the universe is about 13.8 billion years old, and when we look out into the cosmos, we see distant galaxies. And when we look at the distant ones, they're all moving away from us. And so for a long time, there's been this idea that, well, if the galaxies are moving away from us now, they must have been closer in the past. The universe in the past must have been smaller in some sense, hotter and denser, everything packed into less space. And that's the Big Bang theory, the idea that the universe was smaller and denser and hotter in the past. And we got really direct evidence of that in the 1960s when we're able to actually see the light from the very early universe.
