Centre of the Universe
Feb 13th, 2017 at 9:09pm
 
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 no center of the universe.

Each point in the universe looks similar to any other point -

we would see all other distant galaxies receding away.

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?

I imagine its like a big balloon, or bomb going off in front of your face, it accelerates.

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.

Q.
Is there any scientific evidence, which supports this 'scientific' hypothesis ?

A.
No. The hypothesis of how the universe came into existence, is a theorem,       and that is all.




And yet, that hypothesis is the best 'scientific' explanation which human minds can offer;

Google;
scientific theory, nothing, exploded into everything

Google;
scientific theory, in a moment, the universe appeared from nothing

Quote:

One moment, no universe.

The next, there is a BIG BANG [which was cause by, NOTHING] and then we have a universe.

It sounds like a magic trick to me.



......Do you believe in magic ?



+++


Yadda explains the [accepted by scientists] BIG BANG theory;

THIS IS WHAT IS TAUGHT TO CHILDREN IN SCHOOLS;





All matter was once compressed into the size of a full-stop-dot, like the one at the end of this sentence >>> . <<<

And then there was an explosion of that matter [i.e. the BIG BANG], which resulted in our present universe of stars and planets.





The material from that explosion [of nothing] then coalesced and was drawn together to form the stars and planets in our universe.

On earth, the molten rocks cooled, life evolved [from what was once those molten rocks!], and here we all are, ...the masters of the universe!
LOL

Here is a nice BIG BANG theory quote from a science article [purporting to be fact] published in that reputable 'science' magazine, 'Discover';


Google it;

"...The universe burst into something from absolutely nothing - zero, nada. And as it got bigger, it became filled with even more stuff that came from absolutely nowhere."

Alan Guth, Discover magazine April 2002




Quote:
......Start, Guth says, by imagining nothing, a pure vacuum. Be careful. Don't imagine outer space without matter in it. Imagine no space at all and no matter at all. Good luck.

To the average person it might seem obvious that nothing can happen in nothing. But to a quantum physicist, nothing is, in fact, something. Quantum theory holds that probability, not absolutes, rules any physical system. It is impossible, even in principle, to predict the behavior of any single atom; all physicists can do is predict the average properties of a large collection of atoms. Quantum theory also holds that a vacuum, like atoms, is subject to quantum uncertainties. This means that things can materialize out of the vacuum, although they tend to vanish back into it quickly. While this phenomenon has never been observed directly, measurements of the electron's magnetic strength strongly imply that it is real and happening in the vacuum of space even now.

Theoretically, anything—a dog, a house, a planet—can pop into existence by means of this quantum quirk, which physicists call a vacuum fluctuation. Probability, however, dictates that pairs of subatomic particles—one positive, one negative, so that conservation laws are not violated—are by far the most likely creations and that they will last extremely briefly, typically for only 10-21 second. The spontaneous, persistent creation of something even as large as a molecule is profoundly unlikely.

Its a 'magic' show folks!

The Balloon and Explosion concepts both have a centre. So where is it?

Bobby, your dementia is accelerating.

You cannot have acceleration without a force. Why has such a force not been detected or hypothesized?

In fact, gravitational attraction could be slowing the expansion and should eventually, in trillions of years, cause a reversal of expansion.

Bobby, you are a prime dill, and a plaything of propagandists.

There is research that demonstrates it is not accelerating deduced from a larger dataset than was used the study claiming acceleration.

The evidence for acceleration does not meet the criteria for significance.

https://en.wikipedia.org/wiki/Accelerating_expansion_of_the_universe

Quote:
Evidence against accelerating expansion[edit]
A 2016 report from Oxford University's Department of Physics and the Niels Bohr Institute in Copenhagen working with a much larger data set has cast doubt upon the arguments for accelerated expansion.[31] Sarkar comments:[32]
The discovery of the accelerating expansion of the universe won the Nobel Prize, the Gruber Cosmology Prize, and the Breakthrough Prize in Fundamental Physics. It led to the widespread acceptance of the idea that the universe is dominated by "dark energy" that behaves like a cosmological constant – this is now the "standard model" of cosmology... However, there now exists a much bigger database of supernovae on which to perform rigorous and detailed statistical analyses. We analysed the latest catalogue of 740 Type Ia supernovae – over ten times bigger than the original samples on which the discovery claim was based – and found that the evidence for accelerated expansion is, at most, what physicists call "3 sigma". This is far short of the 5 sigma standard required to claim a discovery of fundamental significance.
