Atomic matter only 4% of the universe

[WouldBe]

I've just looked up parallax and hadn't thought of using it in that way.

Those astronomer types really are terribly clever chaps. It never ceases to amaze me the way they combine so many different techniques in order to measure things that, intuitively, you wouldn't ever think possible!

 

[Blagsta]

If the star you are looking at has a 'red shift' how do you know if it is moving relative to earth or if you are actually looking at a red giant?

iirc from my A level physics, red shift is about the shift in absorption lines, so its a quite obvious difference.

Your mama is so fat her mass makes up 95% of the universe.

Depends what you mean by empty.

The pedestrian definition would be "lack of matter". A room with nothing in it is "empty".

If empty is defined as being devoid of all forms of matter and energy, then contemporary physics would seem to suggest that there's no such thing as "empty". There's stuff (matter or energy, virtual or otherwise), everywhere.

And if we follow that definition, then "empty" is a meaningless concept. There's no such thing as empty. When the red lights flashes on your fuel gauge, it's a blatant lie....

Maybe ultimate empty is just very very cold, so cold in fact that time comes to a complete local stop, and because we live 'inside' time, we'd never noitice anything truly empty, because to observe true emptiness would be to fill it.

The way I feel right now I think I am observeing true emptiness, and yes time really does feel like it's gone out the window.

How much did you know about E=MC2 before you excepted the theory of relativity?

after the quantum mechanics/ mathmatics debate even einstine didn't think e=mc2....

I realise that but I wouldn't have been able to understand any more than the basic princible anyway.

It's e=mc² !!!!!

You lot keep reducing the energy potential of matter by a factor of 150000!!!

Stop it.

Stop it.

[pedant mode]

it's e²=p²c²+m²c^4 actually

how'd he do that superscript?

The flow of time does not depend on temperature!

Dark matter is appearing from nowhere meaning the big bang theory that the universe came from a single point is bollocks.

It doesn't mean that at all.

 

[ATOMIC SUPLEX]

It doesn't mean that at all.

Oh hello you.




Yes and no

I see what you mean but check out the whole thing and see the reasoning behind it, it's pretty intresting stuff.

 

[TAE]

It's a unicode character. Just like ½.

Start => Run => charmap.exe

 

[Diem K]

WTF?

But why are all the findings not published? They should have been out two years ago.

What are the lizards keeping from us?

I don't think there is a conspiracy here.

The is a big difference between "data" and findings/answers/hypohotheses.

Two years is also a very short period in terms of scientific progress.

 

[blamblam]

Just to register my interest, for ATOMIC's sake

 

[Truly Topcat]

So if the Universe is finite what is beyond it then?

Please respond in little words, I'm not very clever.

 

[Diem K]

Dimensions (spacial & temporal) do not exist outside the universe.

(or in the event that there are more than one -> outside of universes)

The anoying answer is: There is no such thing as beyond the universe.

Even more anoying is: Its not even nothing, there is just no such thing as beyond.

And thats all that can be offered to us by the brainiest brains of all time, I confirm I am not happy with this either.

Nor me.

The Universe definitely comes to an end somewhere, and at its end something less than nothing exists in its place?

But surely for there to be nothing it has to be something doesn't it? I said I wasn't very clever!

I am no expert either but I have expressed a an interest in this.

What gets confussing is that the "edge" of the universe is not determined by spacial dimensions.

When the scientists gaze into space its like looking back in time. The speed of light and the age of the universe is determines how far they can see.

The big bang was apprantly 15 billion years aso, so when you look into space the "edge" that cannot be seen beyond is 15 billion light years away.

They cannot look any further because before the big bang the universe did not exist. There is no such thing as before the big bang because time was created in the big bang along with space.

Therefore there is no such thing as beyond the universe.
