Are there any other theories aside from the mainstream big bang theory that you think is a likely explanation of our universe?

I have heard of a few scientific theories that aim to explain the origin of our universe that I think are interesting. There is String Theory, for example.. Or the theory where the universe started from different, smaller explosions... Or a multiverse theory where our universe may be one of many universes out there that formed in the same way galaxies are born but on a bigger scale. There's even Simulation Theory that people like Elon Musk find possible. Do any of you subscribe to other theories aside from the mainstream Big Bang Theory as an explanation for the origins of our universe? Let me know what you think 🙂

I like the simulation theory. Of course, being a software engineer helps. After all, reality is just the interface of the senses. But I think it's meaningless to ask what it is interfacing with.

The Big Bang is so wrong its amazing anyone could think that its true.

Why do you say this?

@indirect76 Because the Universe had no beginning, and yet it tries to explain a beginning.

The thing that bothers me is, what's done with knowledge gained from the past? I agree it is fascinating, but in the end, what do we do with the information? I hope we don't try to create any other worlds or universes because we have already littered up this one.

Quite irelavent to the crisis of meaning . You will find your own answers or not most will not involve theories just a way of coping.

There was no beginning - Infinite space has always been here.

I'll stick with the inflationary model of the Big Bang as long as the evidence continues to support it over anything else. The rest are pretty much speculation and, as much as I love speculation, that's where they'll remain until further evidence suggests otherwise. Emergence is interesting and I look for more along this line to explain anti-entropic development, but it's not about cosmological origin. String theory remains that and evidence to support it is a major issue. It's also not an origin theory. Simulation is still SF. Here's a recent article that provides a brief history of our understanding of cosmological origin:://www.space.com/16042-cosmology.html I am particularly interested in dark matter/energy which apparently make up about 95% of the total mass and energy (in other words, everything) in our universe, according to current evidence--and we can't understand determine what it really is. Another way of looking at it is to took around the room you are in and realize that 95% of what's there right now is totally "invisible" to you--and you're full of it. (Some will probably say I am that, too.)

There is M Theory/Brane Theory, which is a product of string theory. I like the neatness of it.

There really is no alternative to BB theory at this point. All of the evidence points to it.

Some version of the big bang probably happened, but I think there is probably much more to it that we don't and may never know the details of.

Multiverse hypothesis = Big Bang still happened
Smaller explosions = Big Bang still happeneed
Simulaton hypothesis = Big Bang still happened

String Theory isn't an origin theory, it's just theory of trying to understand particles and how they interact in our universe.

The big bang is the only theory we have at the moment that is demonstrable true. Anything more than that is just a hypothesis.

But CREATION!!!! D'uh! XD

Because Christians can not figure out how the universe began they like to say "God did it." But have "faith" .....eventually SCIENCE will supply the answer.

I’m not sure the Big Bang theory is much of an explanation myself.

Magic?

The origin of the universe is not a question that has ever cost me any sleep. We are here and this is happening: okay, then.

All are theories and can never be proven with 100 percent certainty, unless someday we create a universe based on one of those theories in a lab.

You have to start somewhere though. We were going to be curious about space and how it works eventually. I think it says something about humanity that we've been able to send people into space without fully understanding it.

Absolutely nothing whatsoever is % certain. There is no actual need for % certainty. In general the preponderance of evidence leans heavily one way or the other and that's good enough for our purposes. Rejecting the best available explanations when the evidence for them is excellent never ends well.

The BB theory fits well with most aspects of observed reality and where the abstraction leaks there are reasonable hypotheticals to explain it. The BB theory is subject to refinement and isn't as settled as, say, the Theory of Evolution, but it is the accepted cosmological model and is very unlikely to be totally discarded due to future discoveries.

One common misconception about the BB is that it explains the origin of the universe. It doesn't; it assumes the existence of matter and energy as a starting point (though not time as we know it). It really just describes what we can observe about the past universe back to our event horizon and the limits of our mathematical models -- and to the "beginning" of time. It inherently can say nothing about what, if anything, lies beyond those boundaries. And it does not require a First Mover or other "cause" because those concepts have no meaning "before" time.

Several of the alternatives you listed could be part of the big bang model, just that the scale would be even far greater than what we know. The multiverse, if it exist, could be multiple big bangs same as the one theorized. The question in mind mind would be if they exist in the same physical realm (i.e. if we could literally travel beyond the bounds of our universe and get to another) or not (physically impossible as the universes exist in different "realms" ). String theory is part of the big bang theory. Simulation is a wash because there would have to be a universe within which some entity had the means to create this simulation, albeit it may be a far different universe than what we know. The notion of scale is abstract; our universe is as big as it is, and any other existing universes or other realms would merely add to that, unless, as suggested by quantum physics, they occupy all the same realm.

Meanwhile, I'm still trying to get the attention of the woman next door.

Our minds are limited to the space/time/matter model, which is nothing but illusion. Questions about when and how the universe sprang into existence can not be answered with that model, and from a higher perspective the questions are simply not meaningful.

I am just reading “Reality is not What it Seems”, by Carlo Rovelli, a physicist who is working on the theories of quantum gravity. According to Rovelli, time does not exist.

The experience of reality is truly awesome and thrilling and joyous, but the implications are baffling in the extreme.

I'm gonna get that book, it sounds interesting.

Rovelli must have been a busy guy. Sometimes I get busy and feel there is no time.

I'm something of a fan of version of the anthropic principle based upon the Heisenberg uncertainty principle and Niels Bohr, conception that physical existence is reliant on measurement and observation, therefore physical existence and consciousness are reliant on each other.
That which is observed requires an observer in order to be observed and therefore exist, the observer requires an observer in order to exist and observe.

Therefore self awareness of being is the root of everything,

Awareness is observation
Observation is measurement
Measurement brings about existence (including time and space)
Existence becomes aware
The circle is complete.

The most efficient way to achieve this is Sentient Life.

Well said! I lean toward thinking that conscious awareness is primary in reality.

Many people say that trump did it. And it's the best universe, this I can tell you.

Lol!

Sad.

I subscribe to the Multiverse Theory

1

Big bang theory makes good sense to me.
For fire is the beginning source of all life and matter. The iron in our blood can be found throughout the galaxy and our bodies is balance heat and particles of metal energy . About 99℅ of earth mass can melt metals. The earth is cooler than the sun and the sun is cooler than the stars. We are stardust children of the stars.

A great being sneezed

or farted... haha

@blueskies not enough matter to much gas lol

@Simon1 i guess that depends on the fart? hahahaha ewww 😮

@blueskies shart??? Lol yup I just went there

@Simon1 bahahahahaha... too funny

It is fun to speculate about such things. I think most mainstream theorists actually hold something of a "multiverse" view these days. I don't think that a theory that "the universe started from different smaller explosions" works very well as it doesn't explain two very significant and curious observations.

The flatness and horizon problems.

I find the simulation theory to be most likely.

Nardi Level 7 June 13, 2018

Personally, I think it is extremely unlikely.

The problem with simulation shows up in irrational numberd such as pi, the natural log and the square root of minus 1. Since they never repeat and never end there is a problem here with the computational power required to keep that part of the simulation going

its only a problem for us within the simulation. I have read somewhere that the smallest scale of movement is akin to pixel by pixel movement.

I wonder if it's a cycle. It's hypothesised the universe will keep expanding, leading to cosmological event horizon and possibly heat death and this will cause a rip or a tear to occur.

This plants the seed in my mind that the tear could create a singularity, like the posited big bang. So I wonder if our observable universe is expanding within the remnants of a previous universe.

@Mortal

Thank you for that. That's very interesting.

I've just been reading about it.. So 'cracks', what ever they are, could prove the theory. I wonder how the cracks would manifest.

Ever read the bible?

Never read it, but I think I know how it ends

The bible's creation story only replaces a natural creation with a god creation which answers nothing and only asks the same question, i.e. where did god come from and an endless regression.

@Bobby9 the question was.... ARE THERE ANY OTHER THEORIES? So that is another theory sherlock, master of deduction.

@Bobby9, @TheoryNumber3 always thought it was open ended. Like a stupid first person video game.

@Bobby9, @TheoryNumber3, @Mortal I read worse. At least the bible one is simple. Six days.... bam! The ones with the dripping butthole or the exploding asshole come to mind. And the turtles and the serpents and the this not real and the aliens, etc, etc, etc.

@Bobby9, @TheoryNumber3, @Mortal, @jlynn37 You may had to define "natural creation". And of course the definition will not make me give a fuck during the rest of my term in this plane so....

@TheoryNumber3 never cared much myself but question was about other theories available.

@GipsyOfNewSpain Your opinion is noted as are the rest of ours. Thanks for your input.

@Mortal what part of mortal you can't identify with? Rant is finished. I simply sugested a different explanation of the universe as it was asked about. Answer to my question was simply yes or no, agree or not agree, liked or not liked. Act like a christian or not act like a christian, on or off, + or -. "Rant" extended for your benefit.

@Bobby9 So now you call yourself an Expert on the Origin of the Universe!!! Which one are You? The Fart of the Big Asshole? The Shit of the Great Dump?
