This is one of many questions to which there is no answer. Some people think it was a deity, though I’m not one of them.
There are all sorts of ideas, I quite like brane theory. The idea of brane theory is that our universe is one of many and they’re all vibrating back and forth. Imagine a stack of sheets of paper, one of them is our universe, the others are other universes. If they were being shaken they would ocassionally collide, and those collisions might cause big bangs.
I think it’s one of the questions we may never answer, but that doesn’t mean it’s not fun to speculate!

Unfortunately we just don’t know! There isn’t any data that we can use to find out what cause it. Maybe if you become a scientist one day you’ll discover something that can tell us and you’ll win the Nobel prize for physics!

You what, that is the question that bothered me the most as well. And even after so many years as a scientist, I still have no answer to it.
It actually bothers me so much that I come to hate the Big Bang theory (the actual theory, not the show, the show the brilliant, and I look like Leonard!).
Studying that question brings you to the realm of belief and faith that we cannot experiment on, and I do not like that at all! In the end, it almost feels more like a metaphysical questions. But if that triggers your brain, I invite to explore that fully and the journey you will get on will be fantastic!

Here’s a speculation – it’s not science, but we’re allowed to speculate about things we can’t really say anything definitive about, as long as we make it clear that’s what we’re doing – and it makes for interesting conversations!
Many scientists have speculated on the evolution of the universe, and many more have turned this into a career – lots of great science fiction does this. So what if the laws of nature, the physical interactions governing matter and energy evolve just like plants or animals do? What if the current, expanding universe is just one phase of this universe’s ‘existence’? Maybe, before the universe was like this, it had a different shape, different rules and then something changed and the universe ‘changed shape’ or something like that…
You see, these questions are important for exercising your imagination – and you need imagination to be a good scientist. You don’t necessarily need to be able to answer these questions – just asking them is important!
