A theory is not a guess, it is a model, and the big bang does have evidence. The more evidence that supports the theory the stronger it is. Science 101

In the beginning there was darkness then bang giving birth to an endless span of time space and matter.Sorry I got it off The Universe.
-
love the video really good
-
Impossible
-
@lucretius1 i think you just got trolled.
-
What was before 'BIG BANG' know one knows..!!! Because God (ALLAH) Exists :)
-
A couple of good videos. I would have two suggestions and one correction.
The fact that that the big bang was the expansion of the universe, rather than an expansion into the universe should be emphasised.
The effect of cosmic inflation on the size of the visible universe should be researched.
The creation of the heavier elements in 1st generation stars should be explored. Fusion did it all is simplistic at best and misleading.
-
@j03y2fly The periodic table is complete and therefore as far as current science is concerned no new stable elements can be created beyond the 92 known. However the possibility of bombarding heavy elements to create further transurranic elements is always a possibility and there is a hypothesised island of stability up around element 116 [I think]. It may be that in the future this hypothesis may bare fruit.

this was a really good video. i think im ganna go to my physics teacher and give him the finger and say i got my physics lessons for the week
-
So can more elements still be created?
-
@lucretius1 SCIENCE BATTLE! i believe u came out on top ;) thanks for the vid dude, extremely informative and helpful, ill look at my universe in a different way thanks to u

No fully formed theory of quantum gravity exists because (based on the perturbative quantum field theory) it requires the use of hypothetical elements called gravitons.
In your definition of the Big Bang theory, you mentioned all the evidence to support it as a theory, but failed to state that the evidence is not 100% conclusive to make it fact, so (in science) a theory is still an "educated guess".

@informationsponge No evidence is "100% conclusive", as further observation can hypothetically disprove it. If theory means educated guess in science, I suppose Newton's Theory of Gravity is such a guess. Though I take it you wouldn't jump off a building to test said theory. Theory is much more important in science than 'fact' (since theories explain facts), something that seems to confuse many laymen because the terms are used in opposite fashion in day-to-day conversation.

@lucretius1
A theory is not only an educated guess, but one's own professional opinion (when evidence runs out and speculation commences - especially in cutting-edge fields of study). Yes. A theory does help to explain the facts supporting any given theory, but (in regards to Sir Isaac Newton) what I think you're referring to - common sense, is something different entirely.

@informationsponge I would hardly call the Big Bang Theory cutting-edge. Yes there are aspects of the theory that require more explanation, but the basics of the Big Bang Theory have been solid science for at least 50 years, it is a theory backed up by loads of facts. Just because Brane Theory and theories like it exist doesn't change anything. That would be like saying quantum gravity theories affect the validity of Netwonian Gravity.

@lucretius1
I wasn't referring to the Big Bang theory as cutting-edge. I meant other more advanced fields of study. You're just looking to argue for arguments' sake. Whatever. I'm finished.

@informationsponge You responded to both parts of my video attacking the credibility of most of my major points - and then after my rebuttals you claim I'm arguing for arguments sake? Come now.
