Empty Space?

Question

The new void in space that scientist found. The one that is about 6-10 lights years away. What do you think the story is behind or "in" it? http://www.canada.com/cityguides/winnipeg/info/story.html?id=c43ca8b4-474d-4db7-a038-a20314e04bac&k=74833

The new void in space that scientist found. The one that is about 6-10 lights years away. What do you think the story is behind or "in" it?

Use your imagination.

Answer 1

The aliens have a cloaking device so we can't spy on them.

Answer 2

OK, here is my imagination.

Space is expanding. Because there is a rate of expansion, then the concept is linked to time.

The theory of General Relativity concludes that time flows more slowly in the presence of a gravitational field. The steeper the field, the slower time flows.

The steepness of the gravitational field is a function of the quantity (and nearness) of mass. The more mass, and the closer the mass, the steeper the gravitational field. As perceived from an outside observer, the slower time will flow in the vicinity of such a mass. If time flows slower, (if we are talking about a very, very large volume) then the slower it will seem to expand.

Here, we have the opposite. We are inside an area with a positive gravitational field (no one has ever heard of a negative one) looking into a volume with no gravitational field. To us (because our time flow is slower here than it is in the void), it will appear that time will flow faster in the void than it does here. Therefore the void has had more time to expand than we think, that is why it is so big.

I know, we are seeing an area that is far away, therefore far in our past. But, it this area was already a tiny void during inflation (when the expansion was a lot faster than now -- and I mean a lot), then it would have grown faster than the surrounding space: this means that matter from the rest of the universe simply never had the time to move into it. It remained empty despite being so big.

As you asked: imagination.

Don't ask me to prove any of it, I couldn't.

Answer 3

To say of this empty space that; "this is accidental"
Is an improper way to look at our universe.
In my opinion, nothing is accidental, we
just need to figure out what makes sense.
That's how Einstien developed his theories.

My personal opinion about this is that
in order for such things to form there must have
been a region where gravity was negative.
That would mean negative gravity pushed matter away.

How could such properties occur?
Well, it is possible that such properties exist in black holes.
That black holes are not singularities but hollow 2-branes,
because the Higgs field value changes within them,
and if a black hole gets big enough, or in other words,
if the negative gravity extends beyond the event horizon,
then the black hole explodes in a kind of a little bang.
It might take many black holes at the center of galaxies
coming together before the black hole is large enough.
This explosion makes a supernova look like a firecracker.
It is possible, that there are a constant (steady state)
series of little bangs that allow this flat universe we see.
This can also account for the irregularities in the universe
like the large void of empty space, etc.
Well....there's my thoughts...take them with salt.

Still....I don't listen to anyone who says things are accidental.

Answer 4

Empty as they might be, they still emit cosmic background radiation. Considering how the rest of the universe is filled with matter and radiation, any concentrated area relatively devoid of matter and energy would be very clearly visible.

Hmm. Maybe scientists finally found the place of the Old Ones?

Answer 5

Where did you get 6-10 lightyears. It´s 5-10 billion lightyears away. And the story is that gravity gobbles up matter leaving empty space.

Answer 6

How is anyone supposed to know? It was only discovered last week. Why not give the scientists time to analyze the data?

Answer 7

Go to picasa pictures and see Vacuum Relativity for answer Seek and you will find correct answer...

Answer 8

If it was empty space they wouldn't have found it because it has no power of emission.
