What is your theory on how the big bang (start of the universe) occurred or triggered?

Nothingness has no dimensions. It has no length height or depth and no duration and so it cannot possibly exist. It isn’t possible for there to be nothing and so there is something.

Theory should be hypothesis in this context.

The beginning of the universe is like an open end, there could be pretty much anything on the other side. That’s why I believe it’s everything, just viewed from a very specific perspective. Same thing goes for black holes, the end of the universe, dimensions outside time and space… This is similar to claiming the earth is round, people don’t believe me.

I don’t have to have a theory myself. I’m not a cosmologist. I do study the subject… for shits and giggles. I came across this today….. https://societyofmodernastronomy.wordpress.com/2016/02/26/once-upon-a-time/

and I’m liking it. It points out one of the biggest and most common errors and that many theories don’t take into account entropy. We wouldn’t exist if it weren’t for entropy, so I think it is rather important.

Turns out it might not have. But if it did, I suspect that having everything that exists densely packed together just wouldn’t be very stable.

The Great Void, or space, always existed as well as all matter that there is. Some if not all matter coalesced into a mass which exploded, creating the universe as we know it, or the part we are aware of. Since time has no beginning and no end, and the matter involved also timeless in one form or another, countless Big Bangs could have occurred.

I’m of the school of thought that believes that time does indeed have a beginning and an inevitable end.

Time is a dimension that like any other, requires a framework on witch it can hang itself, or shall we say travel through.

In other words, if there is no mass and no energy then there is no time as time would not have anything to influence.

Regarding the OP:

(Opinion) Our particular Universe was formed when it violently leaked out of a neighboring one.

Universes are very many and varied, like bubbles in foam in top of shampoo in a bottle.

I’m reasonably certain that The Big Bang theory is today’s plausible theory based on an incomplete understanding of the science involved.

Only mankind would have the hubris to think in under 100 years we could figure out what happened billions of years ago.

I wouldn’t even try or begin to understand. So out of my realm and my understanding. I trust the scientists to figure it out.

It’s a likely a“program” in the sense that it was set into motion and allowed to follow its course. The fact that things actually do progress seems to imply some form of computation. The simulation hypothesis is one I find very interesting. If we really discover that the universe is fundamentally made up of discrete parts and states then it can be completely described using only information. We could in theory “simulate” parts of it using simple ones and zeros 01101000 01100101 01111001 00100000 01101101 01101111 01100100 01110011 00101110 00101110 00101110 01100110 01110101 01100011 01101011 00100000 01101111 01100110 01100110

“Somethingness” and nothingness have much more in common that one might initially think.

Some believe that true nothingness simply isn’t possible.

@SecondHandStoke I love that train of thought, I have ridden it many times. I wouldn’t go so far as to say nothingness is impossible but nothing is the lack of anything which is abstract by its very definition. The lack of anything has never been encountered or observed. The vacuum we know isn’t nothing, it’s the distance between things and it has properties which define it like relative position. Basically nothing ceases to be nothing if it has any relation to anything.

So is “nothing” just a abstract concept? A rhetorical device? Perhaps not, for though nothing is defined by anything, everything is also defined by nothing. Everything is the lack of nothing, if anything lacks from everything it ceases to be everything. So like you say, @SecondHandStoke , they have a lot in common :)
