How can a single Big Bang be true?

In summary, the conversation discusses the possibility of a single Big Bang and its validity based on observations and evidence. While some argue that the concept of a single Big Bang is impossible due to the disappearance of matter into multiple black holes, others point out that this does not affect the validity of the theory as it is based on observational support. The confusion seems to arise from a misunderstanding of what the Big Bang actually refers to, as there may be other events that occur in the far future.

How can a single Big Bang be true if matter is disappearing into multiple holes within multiple galaxies throughout the cosmos and no matter how far back into the cosmos scientist look the galaxies are as mature as the galaxy we reside within?What matter will be left exactly to actually disappear into this single hole scientist speak of?

A single big bang is an impossibility according to actual observations.

Cosmic inflation is a major point behind the idea of the Big Bang, since that interpretation of the redshift/hubble constant (inflation) still holds strong, Big Bang remains a reasonable possibility. Regarding the mature galaxies , I am not aware but there is possibly an explanation within Big Bang cosmology. Big Bang might be wrong but then you need to explain the hubble constant/CMB in a different way. What you are saying about matter doesn't follow to make the Big Bang model impossible

I really have a hard time figuring out what you mean. Looks a little bit like word salad.

But as matter is disappearing into multiple holes in multiple galaxies at varying timescales then it clearly isn't going to all disappear into a single hole. So what do you mean by your statement below? Please explain why you think that a single big bang is still possible if no matter is left?

Who said it has to? Why are you bringing holes into this?

No matter is left when? Where? Maybe tell us what do you think Big Bang means?

It's not, because I see no connection to what Big Bang is - a hot, dense, rapidly expanding state of Universe some time ago. What it has to do with holes and disappearing matter?

Well if the single Big Crunch isn't true. How can the single Big Bang be true?

Are you referring to black holes? Black holes aren't literal holes. Matter and light pass the event horizon, yes, but Hawking radiation provides a method for all of that lost matter and energy to make its way back out eventually. Assuming that Hawking radiation is real (we haven't observed it yet, but we don't expect to given that its intensity scales inversely with black hole mass) then there is no discrepancy.

Even if matter and light disappeared forever, this has no bearing on the validity of a single big bang.

It can be true because we have a lot of observational support for it. And I see no connection to what you wrote in other posts. Again, I think the problem lies with some misunderstandig of what Big Bang is. Tell us, what do you think it is.

PS. After @Drakkith post I think I undestand what you mean.

It seems you are confusing two things, you might have seen some videos that hypothesize the further evolution of our universe, that after trillions and trillions of years, all matter falls into black holes and even evaporates, leaving nothing but empty space. This "ending" doesn't necessarily have to do with the "beginning", the Big Bang theory.

I am not referring to "black" holes no. I am referring to "holes" The correct scientific terminology.

As matter is appearing and disappearing from/into multiple holes, all the time, at varying timescales and not a single hole then of course it has a bearing on the validity of a single big bang.

Observations support an expanding universe, not a contracting one. They also support the idea that the expansion is accelerating, which means that the rate at which the expansion is slowing is itself slowing. It's a bit like gradually letting off the brake as you approach a red light. You're still decelerating, but the deceleration falls over time.

This is entirely false. There are no known 'holes' in the universe.

I don't understand what is meant by this "single hole".
Do you have a reference for it, i.e. from where you heard it/read it?

The only holes that are scientific and observed in this context are black holes.

Where did you get that? Can you give us a source?

I'm not confusing anything at all. Matter is entering and existing the cosmos from multiple holes at varying timescales within multiple galaxies throughout the cosmos so what matter is it exactly that scientist claim came from a single hole and will disappear into a single hole?

To the best of my knowledge you are mistaken. If you believe otherwise please find a reputable source and contact myself or another mentor so we may discuss the issue.

A single Big Bang does not require a single Big Crunch before it.
 

FAQ: How can a single Big Bang be true?

How can a single Big Bang create such a vast and complex universe?

The Big Bang theory posits that the universe began as an incredibly hot and dense point approximately 13.8 billion years ago. From this singularity, space itself expanded, leading to the formation of matter and energy. Over billions of years, gravity and other fundamental forces shaped this matter into galaxies, stars, and planets, resulting in the vast and complex universe we observe today.

How does the Big Bang theory explain the uniformity of the cosmic microwave background radiation?

The cosmic microwave background (CMB) radiation is the afterglow of the Big Bang, permeating the universe. Its uniformity is explained by the theory of cosmic inflation, which suggests that a rapid expansion occurred fractions of a second after the Big Bang. This inflation smoothed out any initial irregularities, leading to the uniform CMB radiation we detect today.

If the universe started from a single point, how do we explain the distribution of galaxies?

After the initial expansion from the Big Bang, matter began to clump together under the influence of gravity. These clumps grew into larger structures, eventually forming galaxies and clusters of galaxies. The distribution of galaxies we observe today is a result of these gravitational interactions over billions of years.

What evidence supports the Big Bang theory?

Several key pieces of evidence support the Big Bang theory: the cosmic microwave background radiation, the observed redshift of galaxies (indicating the universe is expanding), and the relative abundance of light elements like hydrogen and helium, which match predictions from Big Bang nucleosynthesis models. These observations collectively support the idea of a universe that began from a hot, dense state.

How does the Big Bang theory account for the formation of complex structures like stars and planets?

Following the Big Bang, the universe cooled and matter began to coalesce under gravity. Over time, these clumps of matter formed the first stars, which then synthesized heavier elements through nuclear fusion. When these stars exploded as supernovae, they scattered these elements into space, contributing to the formation of new stars, planets, and other celestial bodies. This process of star formation and destruction has continued, leading to the complex structures we see today.
