And we do see that shockingly, we actually do see that. When we use microwave tpoecleses, we see this background light every direction we look. You know, at the edegs of our vision, is this heat, this fire, and we know that it's heat, we can analyze the serutcpm of the light and we can see that this microwave lhgit, this radiation, is the kind of light you get when something is just glowing because it's hot. And so we can see that every doriceitn we look, if we look far enough away, we’re looking so far back in time that we're seeing a universe that is still on fire.

So that's the Big Bang. Exactly what hpepaend, you know, around that time, how that fire got started, that's a whole other very complicated story that we're still figuring out. So we think that, you know, before the fiery part there was this inflation, this rapid expansion. Before that, maybe there was a singularity, maybe not, we don't know. We don't know what started that rapid esapionxn. But we do know that for the first 380,000 years of the cosmos, it was this sort of, all of space was filled with this fire. And we know that because we can see it.

And we do see that shockingly, we actually do see that. When we use microwave __________, we see this background light every direction we look. You know, at the _____ of our vision, is this heat, this fire, and we know that it's heat, we can analyze the ________ of the light and we can see that this microwave _____, this radiation, is the kind of light you get when something is just glowing because it's hot. And so we can see that every _________ we look, if we look far enough away, we’re looking so far back in time that we're seeing a universe that is still on fire.

So that's the Big Bang. Exactly what ________, you know, around that time, how that fire got started, that's a whole other very complicated story that we're still figuring out. So we think that, you know, before the fiery part there was this inflation, this rapid expansion. Before that, maybe there was a singularity, maybe not, we don't know. We don't know what started that rapid _________. But we do know that for the first 380,000 years of the cosmos, it was this sort of, all of space was filled with this fire. And we know that because we can see it.

Original Text


And we do see that shockingly, we actually do see that. When we use microwave telescopes, we see this background light every direction we look. You know, at the edges of our vision, is this heat, this fire, and we know that it's heat, we can analyze the spectrum of the light and we can see that this microwave light, this radiation, is the kind of light you get when something is just glowing because it's hot. And so we can see that every direction we look, if we look far enough away, we’re looking so far back in time that we're seeing a universe that is still on fire.

So that's the Big Bang. Exactly what happened, you know, around that time, how that fire got started, that's a whole other very complicated story that we're still figuring out. So we think that, you know, before the fiery part there was this inflation, this rapid expansion. Before that, maybe there was a singularity, maybe not, we don't know. We don't know what started that rapid expansion. But we do know that for the first 380,000 years of the cosmos, it was this sort of, all of space was filled with this fire. And we know that because we can see it.
