Question: i have been told that the big bang happened from nothing. how can you describe 'nothing'? there has not been a discovery in the knowledge of scientists, everything that we know of contains something!
Great question… and one that is slightly hard to answer! There was simply nothing before the big bang, no time, no “stuff”… no nothing! This kind of goes hand in hand with inflation theory! Where nothing expanded into what we have today!
The last bit is also misleading! Space contains nothing so to speak! It is a vacuum and by definition contains nothing (okay it contains planets you got me… but they are their own things!)
