The evidence for the big bang is an awful lot stronger than just the Red shift. The point about the Red Shift is that all distant galaxies show it which means that everything is rushing away from us. Moreover using stars called cephid variables it was shown that the further a galaxy is away the faster it is receding. The only way this works is if the universe is expanding and carrying all the matter with it like currants in a cake as the cake rises. Obviously you then run this backwards and find a point of origin. The big bang.
On top of this it was calculated that if the big bang occurred we should be able to observe the leftover radiation the "echo" if you like. Indeed this was picked up in 1963 - somewhat by accident but it was almost exactly what had been predicted and is uniform in every direction and almost impossible to explain by any other means.
Fred Hoyle was the last serious opponent to the big bang and he accepted it shortly before his death.
the big bang is only a theory in the same way that gravity is - you might wake up tomorrow to find your nose pressed to the ceiling - but I wouldn't lay odds on it.
Depends on what you think made the universe.
If God made the universe he simply created matter from nothing. (im agnostic, i dunno)
If it created itself then we haven't got the knowledge yet to find out how.
If another race created the universe then they must either:
Energy is something too often misunderstood.
The statement that everything in the universe is made of energy is fundamentally misleading as is the statement that light is the purest form of energy.
Energy is a property of an entity - like it's colour. That entity may or may not have mass. If it has no mass (in the case of light) that does not make it "pure" in any way.
If I hear the expression "pure energy" one more time I think I'll scream.
There is no such thing as pure energy any more than there is such a thing as "pure mass" .
