2011 Nobel Prize in Physics

[Doommage33]

i finally found a youtube conversation where an intellectual argument is taking place....am i dreaming?

[Canadianloyalist123]

@Doommage33 No ,your internet connected to a network which now acts as a wormhole and this is an alternate reality conversation, all explained in string theory.

Yes, the accelerating expansion does look like anti-gravity but dark matter has regular gravity and, as the old joke goes, gravity sucks.

Seriously, dark matter was discovered precisely because of it's plain, old, ordinary positive gravitational effect on the orbital velocities of the stars in the outer regions of galaxies. (Google "Vera Rubin")

Whatever dark matter turns out to be, WIMPS, MACHOS, or something else, it is defined as a source of unknown, attractive gravity not anti-gravity.

[socratus1]

What was before egg or chicken? Oh, I know this question is very old and does not have answer Therefore I will ask a simpler question What was before big bang or vacuum ? Nobody knows the reason of big bang I know Action when God compressed the whole Universe into his palm scientists named singular point And action when God opened his palm scientists named Big Bang # Dark Energy may be Vacuum ww eurekalert. org / pub releases /2007 – 01 uoc – dem 011607.php

Nobel prize in physics 2011 is awarded to the three scientists who discovered that universe is expanding, This scientific fact was mentioned in the Holy Quran ( The Muslim’s Holy Book)

وَٱلسَّمَآءَ بَنَيْنَـٰهَا بِأَيْي۟دٍۢ وَإِنَّا لَمُوسِعُونَ" ﴿47﴾سورة الذاريات)

(47) And the heaven We constructed with strength, and indeed, We are [its] expander. ( sorat Al Zaariyat)

[srinivasaraobukkuru]

not only china...but many other countries can't get noble prizes. The reason is an open secret...

[wabwab2754]

Chinese cannot get Nobel prize. The reason is that China doesn't invest in the Nobel fund.

For instance, Japan invests about 1.5 billion yen in the Nobel fund every year.

Hubble already proved it in the 1920's that universe is expanding with the dopler effect. And ive seen earlier documentaries about supernovas being used to prove the expansion of the galaxies.

[deedubya286]

@zukodude487987 That's true but it was always assumed that it was slowing down due to gravity. The big question was "is it slowing down enough to stop and re-collapse?"

These teams discovered that it is, in fact, speeding up due to the previously undiscovered dark energy. In essence they discovered 75% of our universe that was previously unknown and that we didn't even know was missing.

[zukodude487987]

@deedubya286 @deedubya286 Who is to say that dark matter isn't the cause for expansion or maybe the universe is curved like a sphere and loops back on to itself. Some said that space itself might be expanding, but perhaps its only been stretched by some extra-dimensional force. Or maybe our space has multiple galaxy bubbles and we are colliding into one.

[deedubya286]

@zukodude487987 I don't see how dark matter could be responsible for expansion since its only interaction with baryonic matter is through gravitational attraction.

As far as any other explanations for the accelerating expansion, I don't think anything is off the table at this point. It's the biggest unknown in cosmology today.

If you want an excellent explanation of some of this I highly recommend Lawrence Krauss's lecture titled "A Universe From Nothing". It's on YouTube.

[zukodude487987]

@deedubya286 You:I don't see how dark matter could be responsible for expansion since its only interaction with baryonic matter is through gravitational attraction.

Me: Gravity is a part of dark matter and The expansion of the universe can be seen as anti-gravity, because it does the opposite of gravity. Perhaps the dark matter gives our galaxies more speed and the halos of dark matter of each galaxy pushes each other away while caarrying the individual galaxies with them.

Teleskåp!

[n310up]

You have not discovered this accelerating. It is already written in the QURAN 1400 years ago. "We have built the heaven with might, and We it is Who make the vast extent". At least you have to refer your researches to Quran!

[nybotheveg]

@n310up that qoute is cryptic and doesn't say anything about accelaration of the univers

[vincentXXX666]

@n310up Keep it for yourself, do you really know how often you read these comments? For every comment I want to pick hair out of my body and now im hairless thanks to you

[deedubya286]

@n310up Funny that you never saw fit to mention this to anyone before the results were announced in 1998.

I guess the Mama Bear's bed being too soft in Goldilocks obviously refers to the existence of gravitationally collapsed black holes, doesn't it?

There are lots of fairy tale videos on YouTube for you people to post comments on. Why don't you leave the physics videos to those of us who understand them?

[azndude3600]

Go Berkeley!!

[trifaymang1]

Ago

[trifaymang1]

Allahu akbar, Holy Quran taught us 1400 years.

[vincentXXX666]

@trifaymang1 STFU

[dboyzumik1]

@trifaymang1 in this context, who and what did the quran taught ? and what do you mean by that ? no-one with knowledge of physics derived from "scientific" laws of the quran will ever be nominated to Nobel prize !!! I hope you'll agree with me on that !!! in addition , never has it been that a real physicist (muslim or non-muslim) based his research on one of the quran's "scientific laws" !!! so what exactly did you mean?

[Tomislavv2]

@dboyzumik1

Muslim do lie extensively. whatch how this "miracle of Quran" is debunked

watch?v=JyqkAFCaNQM

Another thing which is obvious to everyone Muslims are living in middle eages,their contribution to civilization today is reflected by amputations,mutilations,Islami­c pedophilia and genocides against everyone.

[Ivaria]

The swenglish is painful /Swede

[Xpl0dable]

so Nobel is fake

[jakubus007]

Congratulation! It's really big deal and discovery!

[eleutheromaniac]

and their explaination is....dark energy. lol. it's well passed time to accept that the big bang theory always was and always will be complete rubbish.

[shakyl008]

go astronomy!

[gear3ful]

They found it out about five years ago. But i have got no idea why it was nominated so late

[Luchs7979]

hä?

das ist doch allgemein bekannt, das die materie sich der gravition entzieht und vermutlich die schwarzematerie das universum noch zusammen hält.

ist das nicht ein alter hut?

verstehe ich nicht!

[balarajappa]

Congratulations:)

[lim4561]

Congratulations! accelerating expansion of the Universe! nice! (don know what it is)
