what is the best way to conceptualize an accelerating expanding, infinite universe?

Question

If the universe is infinite, than it is expanding into nothingness? How do we know that this empty space is infinite? Is it possible/logical for there to be many 'universes' at various stages of development throughout this infinite space?

Answer 1

Once you passed this point where our massive telescopes can't picture anymore, speculations begins.
I think science won't ever be able to answer this, if you seeked math laws, the infinity definition means a limitless quantity, it's a time without end.
I can't comprehend or imagine that place that the space is expanding to or occuping, It has to be a place dark with no matter, got to be antispace !!!
I believe space is a circle, it will expand infitivley onto itself.

Answer 2

I honestly believe there is no "best way" to conventionalize anything that is infinite.
I don't believe the universe is infinite - infinite is a mathematical term and doesn't apply, in reality, to anything we know of outside of mathematics.

For instance, if there were an infinite number of stars in an infinite universe, the sky would be infinitely bright - both day and night. This is simply because, no matter how far away or dim the stars' light may be, there would be an infinite amount of them, and hence, an infinite amount of light.

Try this theory:

Space is 'nothing' without objects - it is only the distance between these objects that make it tangible.
As the universe expands, and it is expanding, the planets and stars are literally creating space. And 'nothing' can easily be infinite - because even an infinite amount of 'nothing' is still 'nothing'.

Consider a box with a perfect vacuum - absolutely nothing inside. It contains 'nothing.'

Now add a couple of marbles to the box and now we something very tangible - we have the relative distance between these two objects. Add another marble and move the box around and we now have both relative motion and distance between the objects - and each marble can legitimately consider itself at rest and determine the motions and velocities of the other two - starting to sound familiar?

The universe is a finite entity,sometime it rather is going to come to an end. It accelerated at an sped up cost for the 1st 30 billionths of a 2nd,reached the cost of light and continued to escalate radially on the cost of light. The universe has a maximum length so finally it rather is going to ought to come to a provide up. The farthest galaxies resolved with the help of the Hubble do no longer exist to-day. The pink shift may be a misinterpretation of what we see performing to be an sped up recession The engine that drives the galactic middle reduces the density of area inflicting a pink shift to emitted easy. The galaxy could seem accelerating away no remember what factor it replaced into considered from. The consensus is that area is increasing yet area is a quantum entity and the quanta can not escalate. The density of area could lessen because it accelerated in spite of the fact that it may finally attain the minimum the place it ought to now no longer exist.

Paint a bunch of dots, equally spaced, on a deflated balloon.

Now, inflate the balloon. The dots all begin to move apart, even though none of them is at the "center" of the surface of the balloon.

Think of the dots as galaxies and the surface of the balloon as space.

The surface of the balloon, which is 2-dimensional in the locale of each dot, curves in 3 dimensions to form the balloon's expanding sphere.

Similarly, 3-dimensional space curves in 4 and higher dimensions to form the universe's expanding "hypersphere".

Like the balloon, the space of the universe has no center. The "center" is really the center of a hypersphere of dimensions higher than 3.

There is also no "edge" to the universe's space either, just as there is no "edge" to the surface of the balloon. A traveller confined to the surface of the balloon (as we are confined to the space curved in a hypersphere) could move in what he thinks is a straight line forever and never come to an end or an edge. He might, however, wind up back where he started!

There are other multidimensional models for the universe which are not hyperspherical, but more like hyperparaboloids. In those models, a traveller could also move in a straight line forever without coming to an end or edge, but would NEVER return to where he started.

As for the acceleration of the universal expansion, you can model this by blowing harder on the balloon! That sounds facetious, but the 2-d model of the balloon's surface will expand at an increasing rate, the same way the universe is observed to be doing.

Anyway, the balloon model is still the most popular way to demonstrate the multidimensional properties of an expanding universe, even though my explanation of it is sheer crap.

Sorry about that!

Hi:

To answer your question we must go back to the Big Bang when are universe started as very high energy light and cooled down to form atoms
in time this light went from x-ray to light to now you find it in the microwave band of the electromagnetic spectrum. until the star from to relight the universe. how do we know this happen because of telescopes and the speed of light. for example you know the light takes eight minutes to travel from the Sun to the earth. So what you ask? well this mean when you see the Sun in the Sky your not seeing as it is, but as it was 8 minutes ago the sun move 8 mintue ahead relative to us on the Earth , This means the when you look at the stars in the night sky your nor see them as they are but what they where in the past, for example Aphla centrie is about 4.5 years from earth now let a say we had a telescope caplable of see the surface of one of the planets and we saw a volanco on this planet blew it top. in 2006. However this really happen in 2002 our time but the light from this planet took 4.5 years to reach us this mean that the farther away a star or planet is from us the farther back in time we are see events and we can see to about 10.6 billions years in time any father and we hit a dark wall this is due to the fact that light from those distance reach of the Universe have not reach us yet and there is a dark age when the Universe big bang light cooled down to a wavelenght below light any way back in the 1930's a man named edwin hubble chart the know objects in the universe Galaxies in fact and he found they where all move away from us and the father the galaxy the faster in appear to be moving, to use a example take a balloon a mark it with some dots space out evenly and start blow up the balloon you will notice that the dot are moving apart from one other. the same thing is happen in our universe the galaxies are move away one from other a great speed Read some books on Astronomy Check the sources I have some shows I want you to see.

Hope this helps
