How has the understanding of the Big Bang changed over time?

Jaelyn Mennell

Well, dude, the understanding of the Big Bang has gone through some serious changes over time. It's pretty interesting to look at the stats and see how our understanding has evolved.

First off, let me give you a quick rundown of what we used to think. Back in the day, people believed that the universe was static and unchanging. But then, in the 1920s, the astronomer Edwin Hubble discovered that galaxies were actually moving away from us, and the farther away they were, the faster they were moving. This led to the idea of the expanding universe, which basically means that the universe is getting bigger all the time.

Fast forward to the 1960s, and some dudes named Arno Penzias and Robert Wilson accidentally discovered cosmic microwave background radiation. This is basically the leftover heat from the Big Bang, which supports the idea that the universe started off as a hot, dense, and super tiny dot. This discovery was a big deal, and it pretty much cemented the idea of the Big Bang as the origin story of the universe.

But that's not where the story ends, my friend. The more we study the universe, the more we realize that we still have a lot to learn. In recent years, scientists have been trying to figure out some of the mysteries of the universe, like dark matter and dark energy. These things are invisible and make up a huge chunk of the universe, but we don't really know what they are or how they work. It's kind of crazy when you think about it.

Overall, I think it's pretty cool how our understanding of the Big Bang has evolved over time. We used to think the universe was static, but now we know that it's expanding and started off as a super tiny dot. And who knows what else we'll discover in the future? The universe is a pretty wild place.
