I don't really get Big Bang

The big bang is but the cycle of energy and matter drawn to a single point in which the energy can no long be held by gravity, it could be one or many cycles running. Pass me the Bong, it's my turn!

Can someone explain...

The First Law of Thermodynamics dictates that Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.

Isn't the Big Bang the complete opposite? Nothing, then massive energy, and then everything in the universe.

Surely if you are a Physicist, and accept the Laws of Thermodynamics, then the Big Bang is about as believable as God?

Yes, in the universe, this essentially is the problem you're talking from the perspective of seeing things from inside of a box the laws of thermodynamics and even the concept of time were created in the big bang itself. Wherever teh box came from or what was the anticedent or whether those concepts even have meaning simply isn't known. This is the great debate of cosmology, no-one knows its all conjecture currently and it has a tendency to get very metaphysical.

n.b. I don't think theres any real question anymore that the big bang happened 13.6bn yrs ago the rest is discovery or conjecture
 
The theory is based on our understanding of how the universe works from a singular planet among infinite others that we dont know about. We are, at best, extrapolating from what we know and we may as well be wrong.
But in response to your actual question, no I cant explain :D.
 
Big bang didn't happen from nothing. That's like saying the twin towers collapsed on their own.

The bang happened as a result of unstable energy causing an explosion. Most likely a black hole so it looked like nothing but in reality it was the exact opposite it was everything.

Maybe go back to using inaccurate thermometers for the wrong purpose like putting them up your bum.

From a philosophical point of view, believing that things that are true within the universe are true for the universe itself is the fallacy of composition.

There's nothing "only" about Big Bang theory. It's incredibly well supported by multiple independent lines of evidence. While there are details to be resolved, if the basic idea of space-time expansion is wrong then our understanding of Physics is wrong.

What happened "before" the first microsecond of expansion or even whether there IS a "before" is currently unknown but science is full of things we don't know, your don't ignore the evidence because you end up in a place with unanswerable questions.

Evidence exists that strongly supports the big bang, IE: Cosmic background radiation
One thing to note regarding law violations that is interesting, when Energy -> Matter occurs ( E=mc2), A particle and anti particle are formed (pair production), when this particle and anti particle collide, it results in what is known as annihilation, and the matter goes back to energy. So when the big bang occurred, Energy -> Matter how do we have any physical matter in our universe? Why didn't annihilation occur, and where is all the antimatter? This is known as the Baryon Asymmetry problem, and violates the current "laws" of physics that we have today, specifically (charge conjugation parity symmetry law). Lots of theories on this, certainly one of the more fascinating questions of modern particle physics imo.

Agree with this also. The James Webb telescope will certainly give us more answers regarding the early states of the universe given its focus on infrared/redshift.
 
The universe is expanding, their was never a big bang it is a term used by idiot's who did media studies that assumes the general public are idiot's.

Big expansion is a better term as the universe has always been around.

OK, so I'll bite*. If the universe is expanding what would happen if you constantly wound back the clock?

*Assuming you must be trolling here as the starting point of an expansions seems blatantly obvious to me.

Which god/gods? Now that's a can of worms.
 
The thing that plays on my mind is humans create these theories or equations and humans are fallible creatures. Technology gets better and theories change based on those improvements.

My theory is energy is infinite and it just keeps going and going. As the universe expands and expands then there's too much energy in this universe and it pokes a hole into the next universe and starts filling up that universe. Rinse and repeat.

This takes into account for multiverses and the big bang was just our universe getting created from the energy of the universe above (or below) spilling over.

What is outside of our universe that the universe is expaning into and is it possible for us to hop between universes and interact with them is what I'd like to know.

Time not being constant like in interstellar really blows my noodle.

There's actually a hypothesis called "The Big Crunch" which states that our universe doesn't actually end in entropy/heat death, that eventually all the matter will snap back together and eventually there will be another 'big bang' which will start things over again.

I think that theory has been abandoned now. There's not enough matter to slow down the expansion in fact recent calculations are that the expansion is actually speeding up!
 
What's outside our universe fascinates us all. What id like to know though, isn't so much what outside our universe, or even what's outside that, but what's outside that!

I'ma guess a Black hole sucks in the universe, spits it out in an explosion, and it happens over and over again

What started it all off though? Science's best explanation seems to be that everything came out of nothing at some point, is it really any better of a theory than creationism? are they actually contradictions except for scientists denying some kind of deity did it?

Scientists do not tend to "deny" things that have no basis in science (i.e. make belief). And yes, scientific theory is much better than make belief stories about how the world came to be. They are the "rules" that physics abides by.
 
There's plenty of videos out there about this. Roger Penrose to the nth degree. A couple more I can recommend are:


and


but if you want to bring faith into it erm yeah that's outside the scope of science but you do you :)

Nothing is outside our universe, our universe is all there is, according to science. We have no evidence other universe exist, only this one. There are theories like '**** bumped into each other and caused the big bang lol' but its just a maths play thing at this point without any observational evidence to back it up.
