New data support Einstein on accelerating universe

Einstein is still the boss, say researchers with the BOSS project for measuring key properties of the universe.

BOSS, for Baryon Oscillation Spectroscopic Survey, has measured the distance to faraway galaxies more precisely than ever before, mapping the universe as it existed roughly 6 billion years ago, when it was only 63 percent of its current size. The findings suggest that the mysterious “dark energy” causing the universe to expand at an accelerating rate was foreseen by Einstein, the researchers reported April 1 at the American Physical Society meeting.

To keep the universe in a static state, Einstein added a term called the “cosmological constant” to the equations for his theory of general relativity; when the universe was later found to be expanding, he called the constant his “biggest blunder.” But in recent years, the cosmological constant, which describes a repulsive force occupying all of space, has been invoked to explain the discovery, first reported in 1998, that the universe is expanding faster and faster.

Evidence for accelerated expansion could be explained either by the negative pressure exerted by the cosmological constant (or some other form of dark energy) or by some flaw in general relativity. The BOSS results support the dark energy picture. “We find no deviations from general relativity on these very large scales,” said Nikhil Padmanabhan, a physicist at Yale University who presented the results and is a coauthor on a series of papers posted online at arxiv.org.

You all ridiculing me here believe government works . You are saying government research works . you all believe government works. I don’t. that’s the difference between you akk and me. You are a socialists/statists. I don’t believe that government should fund research because government corrupts it. You are all citing government research yet none of you nor your scientists can answer the questions I posted proving again I’m right . Answer them what is space, time. what was there before the universe, where does it end , what is beyond it? Why do they say that we are made up of little tiny solar systems called atoms that are mostly space , and that the electron is not really there but only a probability function. come on answer at least some of them any of you.

No ridicule from me.

God’s Grace to You and Yours.

Yeah, Especially the theories whereby we light our cities and split the atom to win WWII.

And make lasers, transistors (by the gallizions on a piece of silicon the size of a fingernail), GPS and the thousand other miracles of every day life today.

“Ordinary matter” falling into black holes contains accelerated charged particles which do emit radiation and are how black holes are detected.

I’m just saying that since we are discovering more and more black holes and there must be many more that are invisible to observation, that they must make up the missing mass that dark matter was invented to fill.

Pretty exciting to know we are going nowhere at an ever increasing rate.

Don't confuse bogus "science" like man-made global warming with legit science. That is not to say there aren't a lot of far-fetched theories out there in the field of cosmology.

Well Dontcha know that it is far easier to use the bogus sciences to denigrate ALL science, especially when some of that other science steps on some of your emotionally held beliefs.
