First of all, what does “Big Bang” really mean? ‘The Big Bang theory is that about 14 billion years ago the universe was in a state that was much warmer and much denser, and that it expanded. That's it, it's not much more than that,” says Raklev. Since then space has continued to expand and has become colder. Based on the theory, scientists have ga...
The Big Bang phrase itself makes it sound like it was an explosion, says Are Raklev. But that isn’t actually that accurate a description. You’ll find out why soon. In the early 1920s, mathematician Alexander Friedmann discovered that Einstein's general theory of relativity provides for an expanding universe. The Belgian priest Georges Lemaître came...
So it isn’t the galaxies that are moving apart, but space that’s expanding. We can think of it as a ball of dough with raisins. The dough represents space and the raisins are the galaxies. Set the dough to rise, and the raisins will end up further apart, without actually having moved. Bringmann uses the surface of a balloon as an example. Draw dots...
If we imagine the Big Bang as an explosion, it’s easy to think that it exploded outwards, from a centre. That’s how explosions work. But that wasn’t the case with the Big Bang. Almost all galaxies are moving away from us, in all directions. It seems like the Earth was the centre of the beginning of the universe. But it wasn’t. All other observers w...
It’s true that our entire observable universe was gathered incredibly tightly together in very little space at the beginning of the Big Bang. But how can the universe be infinite, and at the same time have been so small? You might read that the universe was smaller than an atom at first and then the size of a football. But that analogy insinuates t...
Maybe you’ve heard that the universe began as a singularity. Or that it was infinitely small, hot and so on. That might be true, but a lot of physicists don’t think it’s a correct understanding. Singularities are an expression for mathematics that breaks down and can’t be described with ordinary physics, according to cosmologist Steen H. Hansen. Br...

Big-bang model, widely held theory of the evolution of the universe. Its essential feature is the emergence of the universe from a state of extremely high temperature and density—the so-called big bang that occurred 13.8 billion years ago. Learn more about the big-bang model in this article.
