Its me, right? Just kidding. We all perceive the universe from our centre. This is yet another subject without a suitable Forum.
The BBC today had this on the matter:

http://www.bbc.com/earth/story/20170210-how-the-universe-can-expand-if-there-is-...

All very interesting, and a better explanation is here:

http://math.ucr.edu/home/baez/physics/Relativity/GR/centre.html

But of course, they both go nowhere. It might be of some use to stop talking about an expanding universe, because that implies a centre. If there is no centre, expansion is a bad definition of the apparant movement of bodies away from each other.

Another problem for my puny intellect is this reference to the expansion of space along with the universe. Greater minds than mine, will be able to explain how nothing can expand to increase the amount of nothing.


There is the problem, for some anyway, of how something can come from nothing. It calls into disrepute the 'big bang theory', which I believe has been influenced too much by Abrahamic religions, whereby they posit a beginning and an end (it also calls into question 'progressive' political and moral ideas). The Hindus were ahead of the game here, referring to the cyclic nature of existence.

The big bang is widely accepted now and all evidence seems to support that, everything in the universe is moving away from everything else at an ever increasing velocity as far as we know, it is an ever expanding universe, my prediction is it will slow and gravity will draw everything back in to another big bang.


How could the expansion be accelerating if there is no motive force? If it were increasing at "an ever increasing velocity" what happens when the speed of light is approached and exceeded? Everything goes black?

And once again Yadda shows he knows diddly squat about science.

Correct - dark energy accounts for 68% of the Universe's energy.


https://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy


What Is Dark Energy?

More is unknown than is known. We know how much dark energy there is because we know how it affects the universe's expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe. Come to think of it, maybe it shouldn't be called "normal" matter at all, since it is such a small fraction of the universe.

68% percent of infinity would be, lets see . . . . . .  running out of fingers here.

Issuevoter, you original question is one of many which mankind has pondered since he started walking upright and looked up into the wondrous night sky. One could take Yaddas approach and put everything down to god and he maybe right, science is striving for answers.
Matter is made up of atoms and atoms are 99.9999999% empty space, including us.
A neutron star is about 20 kilometers across and has 200 billion times more gravity than earth, the empty space has been squashed out of it from the way I read it.
Gravity really sucks and now my head hurts.
Since the ever expanding universe at an ever increasing velocity and the big bang theory has not been disproven that will do me.
As for what created matter then what created that.

My original question was an aside. More nothing out of nothing. People who talk this way, expect everyone to know that when they say space, it doesn't mean space any more.

Yadda's most significant contribution is his opening Text which is LOL

"LOL It is all just another human supposition, in an effort to try to explain our existence and self awareness - without involving any necessity for the existence of a creator."

The problem with Yadda's  Laugh Out Loud is its arrogance. Science cannot be said to not exist. As such, it is part of any universe, creationist included. Yadda is not quite sharp enough to realise that science may actually prove creation, and therefore he, and the rest of the God Freaks, would do well to stop being so smug.

I don't think of your time as wasted. The overall discussion so far, has been quite interesting, even if it goes nowhere. An expanding Universe observed and calculated is always interesting. I just cannot take seriously the consideration of nothing as something.

Thanks for this video. I listened, as carefully as I was able, to what Krauss had to say. Very early on, I found myself needing to have points clarified, but that is true in most technical and mathematical discussions.
I still feel that he, representing the latest thoughts on physics, is rather loose with important words. This looseness makes assumptions about the perception of the audience, and God Freaks do this all the time.

That was a long lecture, I only nodded off a couple of times. My take on it is their is one atom per cubic meter of space combined with dark energy. The bozon collider, dubbed the god machine has created a collision of protons which in turn created other stuff.
Their lies the beginning of the universe. Problem solved.

The recent discovery of gravity waves as theorized by Einstein are said to have come from the big bang.
