Everything starts somewhere. For me, it’s here and for the universe, it was the Big Bang. The Big Bang as you probably know was a big explosion that created the universe. But why, how, when and where. But let’s go more in-depth into the explosion. What exploded? A singularity. An infinitely small, infinitely dense dot in space-time. A black hole has a singularity in the middle of it too. Lots of people say that it started by two atoms colliding, but this isn’t true. You see atoms are quite small relative to what we are used to and surrounded by. An average 10-year-old has many trillion atoms. But atoms are not infinitely small. The singularity is infinitely small remember? So let’s go smaller into the realm of subatomic particles!
Atoms are constructed out three key subatomic particles. The electron, the proton
So did the Big Bang begin with two subatomic particles colliding? Well, most likely not. As all the matter was in a singularity, this would have meant that all of the matter would have been squashed together and not moving. So how did it all begin? The true answer is, well we don’t know. Christians think that God said
“Let there be light”
Although scientists believe that the Big Bang created space-time. So there was no time before the Big Bang to say
“Let there be light”
But on the subject on time, when was the Big Bang? Simply 13.7 billion years ago. But are we just interested in when the event happened, not what happened after? That’s what I thought. Well just have a look at the picture below and click on it to get some more information(not sponsored).
But how. How do we know this? Well, all of the singularity quark-gluon-plasma stuff had been tested in CERN’s LHC (Large Hadron Collider). As for the age well click that image up there ^. But what about the Big Bang itself. Why do we think that created the universe? It all started with dust. On May 20, 1964, Robert Wilson and Arno Penzias were using their radio telescope. The images were a bit muffled like there was dust on the detecter. Some deep cleaning later the muffle was still there! They rotated the telescope to see if it was that area in space, but it was everywhere! Later they started hypothesizing what it could be and it turned out to be the cosmic microwave background radiation. Here’s a picture of the universe from Earth in the wavelength of the microwave spectrum.
I may have not begun my journey quite as spectacularly as the Big Bang but everything begins somewhere. And this website is where your journey begins. With your first steps into the Universe!
