New Theories / Re: What is the real meaning of the most-distant-quasar/galaxy?
« on: Today at 00:39:46 »
Quote from: Dave Lev on Yesterday at 17:35:46
Hence, As you go further back in time, the density of all matter increases and the "bubble" that represents our observable the entire infinite Universe gets smaller.

An infinitely-large Universe can't become smaller if all of space is shrinking at a finite rate.

So how can you claim that a theory for a universe that starts as a grapefruit size after the bang and the inflation, could perfectly work while at the big bang moment it is already infinite?

Because the "grapefruit size" thing only applied to the observable Universe, not the entire Universe. Let's not get those two things confused.

That is incorrect as the density of matter in our real infinite universe is fixed over time.

Not according to the Big Bang theory, it isn't.

Quote from: Dave Lev on 17/05/2022 04:54:08
This could be correct ONLY if you shrink the observable Universe while there is no change in all infinite universe outside that observable universe.

Not so. All areas of the Universe would shrink more or less equally.

Quote from: Dave Lev on 17/05/2022 04:54:08
So, how we prove that only the Observable Universe shrinks?

There's no need to.

Quote from: Dave Lev on 17/05/2022 04:54:08
Now do you think that as we go further and further back in time, the Universe M could shrink to zero (or close to zero) in just 13.8 BY?

Possibly. It depends on the maximum possible density (whether or not that density is infinite). Universe M would have been an awful lot smaller at the Big Bang either way.

Quote from: Dave Lev on 17/05/2022 04:54:08
If not, then as the total Universe is infinitely-large at this point, it would still be infinite even if we shrink it by go back 13.8BY in time.

That was my entire point. It demonstrates how the Universe as a whole can be infinitely large at the moment of the Big Bang even though our observable Universe was still incredibly tiny.

Quote from: Dave Lev on 16/05/2022 14:52:43
So, how that "gravitational singularity, a billionth the size of a nuclear particle" could suddenly be considered as Infinite space without breaking the BBT theory?
We also know that there is no empty space with no energy. Therefore, if the Universe started off with an infinite size then by definition it should have some sort of energy.

That does seem counter-intuitive at first, but a singularity of zero size would have made reference to our observable Universe, not the Universe as a whole. To help you understand, consider looking at it backwards through time. You start off with a universe of infinite size, with roughly the same (low) density everywhere. Our observable Universe is a sphere of limited size within this larger Universe. As you go further back in time, the density of all matter increases and the "bubble" that represents our observable Universe gets smaller. However, the Universe as a whole is still remains infinitely large because no degree of shrinkage can change that. So as you go further and further back in time, our observable Universe continues to shrink until it shrinks to zero (or close to zero) size at the moment of the Big Bang. The total Universe is still infinitely-large at this point, however. It's just that the density everywhere is infinite (or at least very, very high).

I would like to remind you that if the universe is infinite, then by definition its age must be infinite.

Not so. If the Universe started off with an infinite size, then it would presumably still be infinite in size even if its age is finite. Let's not confuse the total Universe with the observable Universe. The observable Universe can have a finite size while the Universe as a whole can potentially have (and always have had) an infinite size.

Once you make a change in the theory - you must make a change in the name.

Please provide an authoritative source that backs this claim up. I'm not aware of any organization of scientists that stated this.

Quote from: Dave Lev on 12/05/2022 13:36:42
Real theory can set only one mechanism.

Provably wrong. In chemistry, for example, there are many different mechanisms that can form water. You can create it by burning hydrocarbons, through the joining of two monosaccharide molecules into a disaccharide, through the fermentation of glucose, through the reaction of a base with an acid, and so on. So there are many different mechanisms that can get you the same result.

Nowhere does the Big Bang theory state that black holes can only form through one mechanism (like the collapse of a single star). If you disagree, then provide an authoritative source that backs up your claim that the Big Bang does only allow one such mechanism.

No, there is no different mechanism

How do you know that?

in my model there is no reason why an electron cannot contain a photon.

Why would it, though?

An atomic nucleus is a conglomerate of many particles. Some particles, like baryons, are composed of simpler particles called quarks. As far as experiments can currently tell, however, other particles like electrons aren't made up of anything simpler.

It looks like Dave is turning this into a duplicate topic of his Big Bang threads. Would that count as derailment here?

Just a brief example:
Let's assume that you are a jet eng. designer.
You had been asked to design a jet engine for an airplane.
However, you have no clue about the size and the total requested load of this airplane.
Can you do it successfully?
Don't you agree that a get engine for 100Kg should be different from a jet for 1,000,000,000 Tons?
Maybe for that kind of load a jet engine is not good enough.
So how could it be that we have any sort of theory for a universe without any knowledge about its total size?

That's a bad analogy. A better analogy would be: I don't have to know how many islands exist in order to test whether or not volcanism is a viable mechanism for producing an island.

Quote from: Dave Lev on 17/04/2022 17:17:50
How could it be that the science community don't care about the size of the universe.

I'm sure they care about it, but that doesn't matter because it may simply be impossible to know either way.

Quote from: Dave Lev on 17/04/2022 17:17:50
To my best understanding, we didn't discover any sort of curvature in space.
If that is correct then it proves that there is no limit for our Universe.
No limit means - infinite.

All measurement have limits of precision. So there is still room for the Universe to be curved, but at a level too small to currently be measured.

Quote from: Dave Lev on 17/04/2022 17:17:50
At least - do you agree that there is a possibility that the Universe is infinite?
If so, do you estimate that the BBT - as is - fits also to the infinite Universe?
Can you really set infinite Universe in only 13.8 BY?

Yes to all three.

is it  possible to say what the water itself is regardless of how our senses perceive it?

Well, water is water, regardless of its phase.

Quote from: yovav on 17/04/2022 03:57:53
Or can it actually be said that we have no attainment in essence?

I think there may be a language barrier here, but I'm not sure what you mean by "attainment in essence".

Unknown and possibly unknowable.

Do you also agree that Bogie_smiles should get a reward for his understanding that the Universe is Infinite?

I don't think he's provided any kind of new, compelling evidence for that.

This example represents an ideal Universe without any sort of heat/energy dissipation.

In other words, the real Universe. Where do you think the heat goes? It doesn't just disappear. It just goes to a different location in this same Universe.

Quote from: Dave Lev on 16/04/2022 08:25:54
I claim that in order to get that kind of infinite activity there is a need for external energy.

A claim that is wrong due to the first law of thermodynamics.

Quote from: Dave Lev on 16/04/2022 08:25:54
However, when you add the impact of gravity - then you actually add new free force that can add new energy.

No, no it cannot. This was one of those false claims I was talking about when I was referring to your Theory D thread being closed.

Quote
He calls it: "the gravitational wave" and I like that name.

Gravitational waves are not tidal forces nor are they just gravity. They are their own, distinct phenomenon. Gravitational waves are to gravity what electromagnetic waves (such as light) are to electromagnetic fields.

Quote from: Dave Lev on 16/04/2022 08:25:54
In any case, if you don't want me to participate in this discussion - I would stop.

That's entirely up to you. If you start repeating the same nonsense arguments as you did in your Theory D thread (such as gravity being able to create new energy, orbiting objects always drifting outwards, the Big Bang not being able to account for an infinite universe, etc.) then I will, indeed, ask you to stop replying to this thread.

Why at least exerting tiny effort to do my experiments?

Would you accept the results if the experiment proved you wrong?
