This Year Physics Nobel Prize

[URAIN]

Do you share for which discovery this year nobel given in physics category ? You may give the link but it is good to share with 4 to 5 sentences.

If, as they appear to be, the findings of the Nobel laureates and their teams are correct, then not only is the universe expanding at an accelerating rate, but the cause of that expansion opens vast new doors. Dark energy, assigned responsibility for the expansion must constitute, if real, the greater part of the mass/energy in the universe. Therefore Perlmutter, Schmidt and Riess have increased the scope of the the universe threefold. That's seems worthy of recognition.

 

(That's four sentences, five including this one.)

I think this is first time, science world come to a consensus about expanding of universe. From giving nobel prize to these persons, science world accepted that universe is expanding.

 

I am pasting it from the site http://science.nasa.gov/astrophysics/focus-areas/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 70% of the Universe is dark energy. Dark matter makes up about 25%. 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. )

 

I do not understand, what it is saying about dark energy ? Does dark energy really exist? where it is?

I think you will find that the expanding universe has been pretty well accepted for well over half a century. The Big Bang has been accepted as the best explanation for that expansion for half a century and an accelerated rate of expansion, for which this Nobel was awarded, for fifteen years.

It appears that dark energy exists. Nothing else can explain (adeqautely) the accelerating expansion. It is everywhere.

You may right. But

 

Some where I had read that "Within the solar system, also within our galaxy, within our local cluster of galaxies, and within our supercluster of galaxy clusters, there is NO expansion. There is not "realy very small" expansion, because gravity wins on small scales. Only superclusters of galaxies are moving apart from other superclusters. There is absolutely NO expansion within a supercluster of galaxies."

 

I had taken it as no consensus in science world about expanding universe.

 

And also I read that nobody knows what dark energy is. You have said 'it is everywhere' it means expansion is everywhere or dark energy is everywhere.

If dark energy exist everywhere, how we have to know it and how it is identified?

 

some one given a link to say that dark energy is not needed to explain equal speeds of the stars in galaxies and the expanding universe. What is your comment on this http://dl.dropbox.com/u/26262175/SagitariusBRprogramDescription.pdf

i question the findings for a number of reasions i light is made up of photions 2 light can be bent by strong gravational fields eg black holds 3 time is distorted near black holes 4 we are talking about light that is comeing from millions of light years away. the light is reflected, refracted and bent by bassing near black holes its frequency must be altered by such a long trip from it`s point of origin. light can mot escape from at black hole so by inference photions must have mass so by reason they must. speed up approaching near a black hole and be slightly retardered traveling away from the black holes gravety well.the density of space is not constant adding to this problem i would like to fave comment on my ideas as i think ihat there is room for these ideas to be tested.
