Abstractly speaking, the universe is arrangements of stuff. There are two ends to possible arrangements: 1. Everything is concentrated into one singular infinitely dense point. 2. Everything is spread out evenly and infinitely thin. In the time-bound perspective you can think of 1. as the Big Bang, and of 2. as the Big Rip. Time requires these geometrical limits to manifest themselves as the force that drives everything apart, which is called dark energy. These ideas were first described in the book "Everything forever" by Gevin Giorbran. Theoretical physicists should take a closer look at his concepts.

So I'm guessing it's not expanding because that would mean it's creating new space and not expanding into a space ? We're constantly moving at a very high rate of velocity through space so how do we know it's expanding really?

I think it's a bit of both. I coded a sim once that has both properties, a basic inflationary universe which evolves conformal cyclic eras embedded in a multiverse. That is multiple conformal cyclic universes exist. It kind of predicts it was inflationary competition between universes that stopped the inflationary process not some quantum transition, although there was the possibility that the internal state of the universe just collapsed into universe scaled blackhole too - there's a certain duality about those two things, so is hard to say as my sim is quite limited once inflation initiates. It also Implied should be a universes nearby us that forced the end of inflation and that generically one universe will tend to ultimately expand faster and deflate its nearest neighbour universe by stealing its energy, until some quasi steady state is reached in the far future and a new "epoch" conformally rescales things. Also predicts a basic fundamental information coupling around 1/24 for inflationary phase.

Space: If the universe started small and expand, it has to expand into somewhere. Which space does the universe expands into? What was in this space before the universe expands into it? how big would this space need to be for the entire universe to expand into? Where did the seed universe get the energy for the bang? Time For an event as big as a big bang, it would take some time for the energy to build up the bang. How long did that take, and how much energy did the bang need? Energy: Energy cannot be created or destroyed. Where did the energy came from to create the bang+expansion, and where would the energy return to afterward? Did the energy came from the seed universe itself or from somewhere else? Why must the universe expand? Why can't the universe to stable? Why can't the universe be eternal and timeless? Why can't little parts of the universe to expand or contract while the universe itself is stable?

The space of the universe does not move into or through another space, the space increases in volume, it stretches. General relativity describes the dynamics of spacetime (like how it stretches or contracts), which can either collapse or expand but cannot remain stable.

Math (or any conceptual things) do not, and did not, have a necessary existence UNTIL things materialized. Math is universally agreed upon nomenclature for the relationship between objects. You can't have relationships between things that don't exist. I believe mathematics came about as physical objects came about. First came the concept of "Zero" and the concept of "One" and every mathematical conceptual relationship between the two that can exist (with only those two in existence) the instant a singular physical object came to be. The rest of mathematics snowballed from there.

@nemethdaniel6384
Жыл бұрын
There are no gaps. The expansion actually means, that the scale-factor changes. The standard metric "rod" of 1 meter gets smaller and smaller. Imagine it in a way, that in the past two galaxies were lets say 1 million meter rod away, but as the expansion was going on (the rod got smaller), the distance increased and now you need to use more of that rod (as the rod got smaller), lets say 1.2 million of them. And an infinite Universe would not necessarily look different than a closed one from our perspective. It depends on the actual size of the Universe compared to the Hubble radius. The Hubble radius is the "visible universe". If the size of the Universe is comparable with the Hubble radius (and is closed) then we would see some curvature effects (like positive cosmological constant), if the size is huge compared to the Hubble radius, but still closed, then we would see a small curvature effect and very tiny (almost zero) cosmological constant. If the Universe was flat (no curvature) it would mean that it is infinite, then there were no creature effects on a large scale and we would have no cosmological constant. The actual situation is the second one (most likely), we see a positive but very small value.

What's upsetting me the most.... When people hear the phrase "Big Bang Theory" now.... They think of that horrible television show. Dr Guth is one of my favorite theoreticians to listen to. You can tell just how extremely intelligent he is, but he is capable of making "normal" people understand what he's saying. As much as we can anyway.

Doesnt this suggest that on the outskirts of the area that inflated you still have that incredibly dense gravitational matter that didnt expand so maybe the acceleration of todays expansion is this matter pulling the universe apart/toward it?

Interesting thought, although I would say most likely not. The speed of the gravitational interaction equals the speed of light (to the best of our knowledge), thus if there was anything "outside" of our bubble, the "edge" of our bubble would close us out from the rest of the inflating whatever. And what is that whatever? It is not a dense matter, but a field, called "inflaton", this field causes inflation, and when it decays slowly, it can decay into other matter fields (according to those who work in this area).

@@nemethdaniel6384 But the way he describes inflation here suggests that however far outside the edge of inflation there exists a boundary of dense matter/energy that never inflated right? What effect would that have?

That comment about the negative energy of gravity being equal to the positive energy of matter, this making the total energy 0 is something I remember from Victor Stinger's book. He was speaking about it as a retort to the argument "why is there something rather than nothing".

One gram? Maybe someone should mention the elephant in the room. I mean, I've heard of wishful thinking but this takes the cake. I sense that science feels more comfortable if the origin of the Universe is so small that we don't need to know how it got there. Maybe Dr Suess should have been a scientist. 😂🤣😂

@@joshkeeling82 thats what you want to believe. But its no really the case. Most of them never even peaked into a telescope. They just parrot someone elses theory and refuse to examine any observations that contradict it. They base this theory of expansion on red shift . Halton Arp who spent more than his share behind a telescope, observed that red shift was not an absolute indicator of distance but his findings were ignored and censored . His telescope time was withdrawn and basically blacklisted for questioning the dogma. So yes in my view established theories have become religious like, and hide behind the cloak of so called science.

The whole thing sounds very speculative to me, and seems to be full of speculations that fly in the face of everything we think we already knew about physics.
