This is why we needed to add dark matter and dark energy.
. How can we still see something that came and went a fraction of a second after the bang!
One explanation is the energy circled back and what we are seeing is an echo.
The problem with that is the original energy, should echo first and not last,

QuoteQuote from: Dave Lev on Yesterday at 05:35:51However, our scientists have used "extrapolating a linear Hubble Law back to time t = 0"https://www.pnas.org/content/112/11/3173Ho, is about 70 km/s/Mpc (where 1 Mpc = 106 parsec = 3.26 × 106 light-y). The inverse of the Hubble Constant is the Hubble Time, tH = d/v = 1/Ho; it reflects the time since a linear cosmic expansion has begun (extrapolating a linear Hubble Law back to time t = 0); it is thus related to the age of the Universe from the Big-Bang to today. For the above value of Ho, tH = 1/Ho ∼14 billion years."That's the simplest arithmetic. If two objects are increasing their separation at a rate of 10 parsecs per century and are currently 1.4 billion parsecs apart, then, barring significant acceleration, they were very close to each other 140 million centuries ago. The whole theory hangs on that simple relation.

The law is an extrapolation, not a law about what is observered, but one about (given a recession velocity) where a galaxy actually is now, not where it appears.
QuoteQuoteWhileV = Z (redshift) * c (speed Light)Reference please. This only works in Newtonian physics. Special relativity gives an entirely different relation that has been verified in the lab, and even SR is not applicable to cosmological scales since the universe is not Minkowskian. The cosmological relation between V and Z derives from various solutions to Einstein's field equations. I use the charts published, and which I've posted before. The v=cz line is nowhere near reality except at very low speeds where Newtonian mechanics is a simple approximation.

Redshift is all about velocity!!!The redshift is based on Dopler effect:https://en.wikipedia.org/wiki/Doppler_effect

How can we still see something that came and went a fraction of a second after the bang!Quite easily.Even if you take the simplistic model of an explosion with a "middle".radiation from "on the far side of the middle" would take a long time to get here.The real answer is that while matter can't outpace light through space, space itself can expand, and that delays and red shifts the light.Quote from: puppypower on 17/11/2020 12:13:01One explanation is the energy circled back and what we are seeing is an echo.What did it reflect from?God's shaving mirror?Quote from: puppypower on 17/11/2020 12:13:01 The problem with that is the original energy, should echo first and not last,Which is another reason to abandon the idea.
Why hasn't our receding universe left yet?

Say we start with the BB singularity.

. Hubble LawQuote from: Halc on 17/11/2020 01:39:04QuoteQuote from: Dave Lev on Yesterday at 17:48:05Hubble law is correct by 100%You seem unaware of what that law is.Kindly inform us, with reference.https://en.wikipedia.org/wiki/Hubble%27s_law"Hubble's law, also known as the Hubble–Lemaître law,[1] is the observation in physical cosmology that galaxies are moving away from the Earth at speeds proportional to their distance."So, if our scientists call it Hubble law, why I can't call it at the same name?
Hubble's law only tells us about the ratio between distances to redshift
a galaxy with redshift of 13 that is moving away from us at a velocity of 13 times the speed of light. (Based ob Hubble law this galaxy is located at 221Gly away from us).
About 100 Years ago, our scientists have considered that we are living in a finite compact Universe. They were sure that Universe has a very limited size and bounded (with clear edge)
However, today we know that the Universe has no edge.
Theoretically, if we could go back in time and observe the Universe with our current technology, we would surly see that the farthest galaxy that we see today is closer.
It is expected that Andromeda should collide with the Milky way in about two billion years from now.
Therefore, by using extrapolation, two billion years ago it was twice further from us and 14 Billion years ago it was 7 times further away.
Therefore, how can we claim that all the galaxies were close together 14 Billion years ago?
However, the Milky Way and Andromeda are very massive galaxies, so it is not realistic that they would be affected by gravity of smaller galaxies.
QuoteQuoteTherefore, by using extrapolation, two billion years ago it was twice further from us and 14 Billion years ago it was 7 times further away.These are close enough to have mutual attraction on each other.

let's look at Triangulum Galaxy. It is located today quite close to Andromeda and actually moving directly away from that galaxy.Based on the same idea of extrapolation – in the past those galaxies were quite closer, or even collide with each other.So how could it be that Andromeda didn't eat Triangulum Galaxy for breakfast when it was nearby? How the gravity push them apart?Hence, If you wish to set extrapolation for large scale, why don't you do it also for small scale?
I'd still like you to explain something really simple which doesn't involve complicated maths.If almost everything in the universe is going away from us, and it always has been (so you claim), for an infinite time, how come it is still here?Why hasn't our receding universe left yet?
Don't you agree that if they should collide in about 2 BY then in the past they were much further away?So, first we have to understand how far away they had been 5By, or 10 By ago.So, why can't we assume that in the past the distance could be higher than 10Mly or even than 20 Mly
If those supper massive galaxies have a mutual gravity attraction, this atraction should be increased as they come closer and closer.Do we see any change in there velocities as they come closer?
The Milky Way and Andromeda are part of our Local Cluster of galaxies, which our bound together by mutual gravitation, and are orbiting their common barycenter.https://en.wikipedia.org/wiki/Local_Group
But each galaxy has its own "peculiar motion" (random velocity) - some will be away from us, and some will be towards us. It just so happens that Andromeda has a velocity that is towards the Milky Way Galaxy (us).See: https://en.wikipedia.org/wiki/Peculiar_velocity#Cosmology
The expansion of the universe is so slight on the scale of a galaxy cluster that it will not disrupt the local cluster (not with the current rate of expansion).
Because these local galaxies are in orbit around each other, their average separation today is pretty much the same as it was 1 BYA or 5 BYA.
- Andromeda and the Milky Way galaxy will collide in about 5 BY. Their speed will increase as they get closer - say, in 2 billion years.
- But the change in velocity over the past century is miniscule, as the distance has hardly changed in the past century (as a percentage of the total distance).
If it is a direct hit, almost all the stars will pass between each other, since both galaxies are mostly empty space.
et's look at Triangulum Galaxy. It is located today quite close to Andromeda and actually moving directly away from that galaxy.Based on the same idea of extrapolation – in the past those galaxies were quite closer, or even collide with each other.So how could it be that Andromeda didn't eat Triangulum Galaxy for breakfast when it was nearby?

Dave, you keep missing this.Quote from: Bored chemist on 18/11/2020 12:52:11I'd still like you to explain something really simple which doesn't involve complicated maths.If almost everything in the universe is going away from us, and it always has been (so you claim), for an infinite time, how come it is still here?Why hasn't our receding universe left yet?
At older age, he considered to reuse that constant in order to support the idea of new created particleshttps://www.discovermagazine.com/the-sciences/einsteins-lost-theory-describes-a-universe-without-a-big-bang"so Einstein proposed a revision of his model, still with a cosmological constant, but now the constant was responsible for the creation of new matter as the universe expanded (because Einstein believed that in an expanding universe, the overall density of matter had to still stay constant)""As for why Einstein was so intent on maintaining the use of his discarded lambda, the constant represents the energy of empty space — a powerful notion — and Einstein in this paper wanted to use this energy to create new particles as time goes on."So, Einstein fully supported the understanding that new particles should be created as time goes on!!!This idea contradicts the BBT and fully supports Theory D as "Einstein believed that in an expanding universe, the overall density of matter had to still stay constant".Therefore - from now on we must agree on the following facts1. Einstein didn't accept the BBT2. I have full approval from Einstein to claim that new particles could be created in our Universe.
So, it is all about the creation on new matter.
Quote from: Dave Lev on 19/11/2020 17:25:05So, it is all about the creation on new matter.So, your idea only works if we ignore the conservation law.It would make more sense to ignore your idea, wouldn't it?
So, if you still think that he is wrong with this idea
It's not that I think it is wrong.It's that I can prove it is wrong.https://en.wikipedia.org/wiki/Noether%27s_theorem
The problem that you face is that it's quite common for dead scientists to have been wrong, but almost impossible for a dead mathematician to be wrong.Maths doesn't depend on observations.

the constant was responsible for the creation of new matter as the universe expanded
What do you wish to prove with this nonsense?
How do you dare to reject Einstein Explanation about new creation particles:
Why when it comes to the dark energy that is created out of nothing you don't care about the conservation law?
So, please would you kindly tell us if that space expansion is affected by gravity or not?
and the inflation couldn't work at all.
Einstein had stated that the BBT is wrong. Therefore this BBT should be considered as a Dead science.

QuoteQuote from: Dave Lev on Yesterday at 11:15:46Why when it comes to the dark energy that is created out of nothing you don't care about the conservation law?I already answered that.It is related to the asymmetry of the start of the universe.

Therefore this BBT should be considered as a Dead science.Einstein had stated that the overall density of matter had to stay constant in an expanding UniverseEinstein believed that in an expanding universe, the overall density of matter had to still stay constantTherefore - the density in our Universe MUST stay constant forever and ever. Hence, the CMBR of our current universe would stay the same forever and ever. That should be correct 100 By ago and 100 BY in the future.Einstein had stated that the cosmological constant is responsible for the creation of new matter as the universe expands The constant was responsible for the creation of new matter as the universe expanded.
QuoteQuote from: Dave Lev on Yesterday at 11:15:46How do you dare to reject Einstein Explanation about new creation particles:It takes no "daring" to point out that someone was wrong. It just takes proof, and I have presented that. It is not my fault that you cannot understand it.
Quote from: Dave Lev on Yesterday at 11:15:46How do you dare to reject Einstein Explanation about new creation particles:
So THE MATHS PROVES THAT YOU ARE WRONG.
So, you and the 10,000 BBT scientists
Einstein knew the answer for that.
Unfortunately you all reject his clear explanation.
Therefore, I would like to highlight several Key contradictions in the BBT with regards to the energy or "Energy conservation"
The Big Bang should have produced equal amounts of matter and antimatter.
So, how that asymmetry could create any sort of dark energy?
At that time more than 99.9..9 of the new created particles pair at the Big bang moment have eliminated each other due to the idea that one is matter and the other is antimatter.So, the OM (Ordinary matter) in the entire Universe represents just the 0.00..1 from the energy at the first moment of the Big Bang.
BC claims that it is due to asymmetry of the start of the universe.
However, the asymmetry issue is all about matter and antimatter.
The math that our scientists are using is based on Einstein formula
I have no intention to argue with you about the New created particles process as it based on Einstein wisdom & Theory.
He had stated that the BBT is wrong, therefore the BBT is wrong.
Velocity - The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference.
How could it be that Andromeda is approaching the MY at a velocity of 300 Km/sec due to the mutual gravity attraction?
In the following article from Harvard it is stated:https://www.cfa.harvard.edu/seuforum/bb_whycare.htm"No one knows how the first space, time, and matter arose. And scientists are grappling with even deeper questions. If there was nothing to begin with, then where did the laws of nature come from?”
“How did the universe "know" how to proceed? And why do the laws of nature produce a universe that is so hospitable to life? "
