I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Disease Zone. It has scientists studying the causes and processes of illness . Who gets the prize? YOU decide!
As a medical researcher, it’s not really my field, but I don’t think scientists know what exactly caused the big bang. I do know they’re trying really hard to out, but they don’t know….

I’m not a physicist, but I can give you a few points in the right direction. The Big Bang is the name of a sudden expansion from a point at the beginning of the universe. The universe began as a tiny point of compressed matter and energy, squeezed down incredibly small and amazingly hot. At that size, with matter squeezed so tightly, the individual components want to get out in a hurry somewhat like the way a crowded elevator full of people empties quickly when the doors open. This caused the universe to expand unbelievably quickly. The way it expanded is often compared to a balloon inflating (and you can try this out at home to get an idea of how it works). There’s a lot of really cool physics that goes on in those first few seconds of the universe, but you’d have to read a book to get all of the details.
The other question is, ‘what happened *before* the big bang to cause it?’ That, we don’t know. There’s some speculation, like the idea of the Big Crunch: the universe stops expanding, slows down, and reverse direction until everything collapses back to a point, the Big Crunch. As far as I know (forgive me if I’m wrong!), the current state of evidence doesn’t really support a Big Bang

Dear Supersaint; ‘Big Bang’ is a hypothesis concerning the beginning of the universe. Hypothesis is a kind of proposal which is yet to be proven. When hypothesis is proven solid and accepted by scientists, it becomes a ‘theory’.
I do not know what caused the big bang and I wonder the ‘Big Bang’ hypothesis will ever be proven to be right or wrong. Therefore, “What caused the big bang?” is a very good question but too big and too heavy question for a hypothesis. Let’s wait and see until you grow up and make this hypothesis into the Theory. You may be able to suggest what caused the Big Bang. How do you like it?

Sorry Supersaint7 – space is one thing that I really have trouble understanding!! As far as I understand cosmologists and theoretical physicists don’t know exactly what caused the big bang. They are working really hard to try and figure it our and find some proof, but as far as I can find in my browing on the net nothing that most people are happy to agree on (but that’s what science is all about – someone will propose a theory, then others will look at it critically and see whther it works or not, that half the fun!).

Unfortunately can’t help you with this one, Supersaint, as I really don’t know much about the Big Bang theory. We’re finding out more and more about what happened shortly after, but I would imagine studying the singularity itself, which is what the tiny point of energy Steven mentioned is called, would be very difficult. However, as technology gets better, and we learn more about the universe, hopefully astrophysicists can start to answer these questions!
Maybe have a look at the questions over in the Boron Zone! One of the scientists, Simon, works at the Australian Astronomical Observatory, so he might know more about it than us Disease people.
