It is a hypothesis, nothing less nothing more.Laughed at in science as much as intelligent design.
As opposed to Intelligent Design which is disproved.

Oh hypothesis sounds scientific like bigfoot ID is also a hypothesis.It is a hypothesis, nothing less nothing more.

separation of a photon from an atom.Almost everything at the macroscopic level has multiple causes. In fact, I would challenge you to find anything macroscopic that only has a single cause.
Hypothesis is a word with a very clear meaning.Oh hypothesis sounds scientific like bigfoot ID is also a hypothesis.
No krauss went into total crackpot loony tune territory. And believe it or not actual scientists can actually have complete crackpot ideas!???? Did you know newton was facinated by alchemy? So would we say "oh its a hypothesis alchemy is true?" or do we say crack pot? Besides krauss has shown he actually is not remotely a logical individual just by his personal behavior!
No, of course not. the singularity is a state.The 'singularity' that most people talk about when mentioning the Big bang is not an event--it is not part of spacetime. In fact, it is *defined* by the fact that spacetime cannot be extended that far. It is more an absence that it is a presence: the inability to extend time past a certain value.
Obviously.No, that is an ordering of very broad occurrences that happened over very large distances, not single events. So, the formation of a galaxy in one place will not be causally connected to the formation of a galaxy at a place distant from the first. The individual stars that form are not causally linked to each other. Etc.
You are focusing on *one* chain among a great many that exist. There is no reason to assume the different chains all link up to a single precursor.
I am waiting for a clarification, @Segev Moran .I thought you meant to discuss the origin of existence instead.
Exactly.The observable universe was once much more compressed than it is now, yes.
But, again, to say there was something that 'made this energy be' implies the existence of time before that energy existed. But, by all accounts, energy existed whenever there was time. That means that the energy, like time itself, cannot have a cause.
Science is based on reality, wouldn't you agree?Absurd, since the very claim of a first cause is based on the predicate of a causeless thing, namely the first one. So, it is logically incoherent to deny it by showing something that it actually expects.
And that is also incoherent in general, since it is possible to have causal sequences that have no initial cause, and yet they are all caused.

HiI'm a bit late in arriving at your thread, so if my comments have already been made please disregard them.
Thats a better stating point than most people hereYup.
Its the same. if time doesn't exists, it means there is no "arrow of time", so events don't occur rather everything exists in the same "frame" of time. this is what i mean by what i wrote.I would say time "didn't exist," but for the sake of your argument, okay.
Okay as agreed? or okay as whatever you say?A first cause of our universe, okay.
As an example:Can't assume that at all. "Placed" implies something aside from and before the initial event. We would need some very good evidence before asserting such a thing. Whatcha got?
The thing is a dot of everything we know.What "thing" is this? The mysterious placer? And to assert that this "thing" contained within it all our reality is too much of a leap over a lot of necessary prerequisite evidence.
Nothing to be sorry about if we all thought the same this forum would render obsoleteSo sorry, I can't go along with your scenario here.
.
Once it is propotional, it cannot be random.I am saying it could have been like that. We don't know, because there is no evidence either way. I am reminded of a discussion Polymath and I had on this forum some months ago, centred around the idea in modern physics that there are some uncaused processes.
The classic example is radioactive decay. Atoms of a radioisotope decay randomly, at a rate proportional to their number and characteristic of that isotope.
AgreedThere is no mechanism known for what makes a given atom decay at a given moment.
Besides the rate.There is no pattern that so much as hints at the presence of any mechanism.
This is a different thing. they are treated this way as we don't know the cause.. not because we know they are causeless.Applying Ockham's Razor, they are treated as uncaused events.
I'll read about it moreThe spontaneous emission process in decay of excited states of an atom is similar. Here, there is an immediate cause, in that according to QED the emission is stimulated by vacuum fluctuations in the EM field. But those fluctuations are themselves uncaused. They just, er, happen, from time to time.
Can you define how science assumes there was a big bang?Now, you may say, "But everything has a cause, so there must be one. We just haven't found it yet". And you might one day be shown to be right. But, as far as science goes, there is no reason to take as axiomatic "everything must have a cause". And, as there is no evidence for any cause, Ockham's Razor wins and we say, "According to our current model, there are uncaused events in physics".
True, we don't really know.I don't think we know enough to reach any conclusions about the beginning of the universe. Our perspective, our entire sense of existence is based on the idea that every beginning has a cause. So here's a beginning looking for a cause. Maybe the universe is an exception to this.
Was there something before our universe existed? Who knows. If there was, we may never find any evidence of it in our current universe.
I guess this leaves a person free to create whatever narrative about the beginning of the universe that suits their fancy. It's unlikely that anyone will ever be able to prove your narrative wrong... or right for that matter.
What would I agree on? I'd agree we don't know, probably will never know. Maybe it's fun to speculate but I wouldn't put a lot of stock into any of it.
Your explanation claimed that if i play a video, there is no meaning to time before 00:00.It didn't confuse me. I just have no idea how it relates to my post. Perception of time is irrelevant to my post.
And this mass energy was always there? sounds like God to meI define a cause as a movement of energy from a region of higher to a region of lower energy, and an effect as the change that results.
So I'm drawn to the hypothesis that mass-energy (or some equivalent of it) is what exists, and that the physical phenomena of our universe, including the dimensions, are qualities or by-products of it. Thus time exists because mass-energy does, not vice versa, and mass-energy's existence is simply a datum, not itself a caused phenomenon.
I have discussed this a lot in the answers hereThe old argument from 'first cause' always had many failings, not least the egregious non-sequitur that the first cause must be God.
These days it has the further problem that in quantum physics we find innumerable phenomena that are not 'caused' in classical terms, such as the spontaneous formation and instant mutual annihilation of particle-antiparticle pairs (whence the Casimir effect) or the emission of any particular particle in the course of radioactive decay. These have instead to be described in terms of statistics within parameters.
Same here.While it's not clear that the Casimir effect has any relevant consequences in human terms, radioactive decay certainly can.
Yeah i canThe classic example is a pencil:
I, Pencil by Leonard E. Read | Leonard E. Read
... but just about anything would do. I can't think of a single thing that only has one cause. Can you?
NopeI thought you meant to discuss the origin of existence instead.
Please note in the OP i say human POV.You Make some sense if realty is a something. But to determine it you would have to be free from it outside of it.
Lol. I am far from normal i fearIf, while you are in it, and make a claim about it, as if you are independent from it thats a personal psychological issue and a troubling mental disorder called NORMAL!
So are you saying you are "normal"? In this type of discussion "normal" debates with itself a variety of views it has of reality as it is standing outside reality!
Normal seems pretty cuccoo to me but hey i am wierd....
Your explanation claimed that if i play a video, there is no meaning to time before 00:00.
I agree. what i wrote was that it is irrelevant to the question of time.
there is no negative time, and i never claimed there is.
in my OP when i talked about eternity, i didn't mean time BEFORE the existence of our universe, rather a point when time was not in "motion" and everything was just there, all at once, no past, present or future.
Your analogy of the Youtube video has got nothing to do with what i was saying before it, so i tried to explain what i meant.

I don't have enough knowledge about our nature of existence so i can't make any claim regarding it.I am waiting for a clarification, @Segev Moran .
Which is it? Are you proposing that humans have a natural tendency to presume a cause-consequence structure in our perception (which is trivial, but true) or are you discussing the nature of existence instead?
Those are two very different subject matters, and you seem to want to meld them somehow.
