Hubble Telescope Makes New Discovery
 

I never knew there was a theory besides the big bang of which I always found boring. I am glad Einstein was right about a theory I never learned about.
It is facinating for the first time so excuse my indulgence to the brains who already knew something about it.

Anyway, I saw this article and thought it very interesting. Plus the hubble pictures are beautiful.

This so-called "dark energy" has been pushing the universe outward for at least 9 billion years, astronomers said Thursday.

"This is the first time we have significant, discrete data from back then," said Adam Riess, a professor of astronomy at Johns Hopkins University and researcher at NASA's Space Telescope Science Institute.

He and several colleagues used the Hubble to observe 23 supernovae - exploding white dwarf stars - so distant that their light took more than half the history of the universe to reach the orbiting telescope. That means the supernovae existed when the universe was less than half its current age of approximately 13.7 billion years.

Because the physics of supernova explosions is extremely well-known, it is possible for the astronomers to gauge not just their distance, but how fast the universe was expanding at the time they went off.


History of the Hubble




"This finding continues to validate the use of these supernovae as cosmic probes," Riess said.

I clear picture of the galaxy.

The "dark energy" theory is not in opposition to the big bang; it's an adjutant. So is Inflation.
As far as Einstein being right -- being right for the wrong reason isn't worth much. One's theory only as good as the logic path that brought one there.

yeah, what Pie said...

another pic of the Crab Nebula on APOD;

the 2nd pic is also on APOD (M51)

Heaven forbid science might not be entertaining enough. They should really try harder to spice it up! :rolleyes:

Thanks for the beautiful links barefoot!

and pie.....
.....and who am I to argue with brains although Albert is probably turning over in his grave ....anew..today.



"As far as the laws of mathematics refer to reality, they are not certain; as far as they are certain, they do not refer to reality."--Albert Einstein

I still give Einstein some credit. He introduced a "fudge factor" because he couldn't identify the reasons that things didn't fit his calculations. Even though he couldn't identify the source of the variations, the fact that his work showed that variations were there is still pretty cool.

I quite agree. I wasn't interested in science and history much until I was OUT of school. Science was my best subject and still I know nothing. :)






He had alot of the puzzle. Scientists still don't know exactly what IT 'THE DARK ENERGY' is...not even a little bit.

Two previous posts on the subject. First was this lumberjim question in
3/9/2004: New Hubble deep field .

Second is a spacecraft to better learn the science -
Alpha Magnetic Spectrometer .

I am a proponent of "variable gravity" & do not buy Dark Energy/Matter.
It is also supported by Einstein.

that egg has a blood spot on it, I'm not eating it.

hum, well, I don't read every thread on the cellar ........and

I was talking about science class theorys but thanks for the links?

Only UT does. That's why he has a superhero name.

Not only do I read every post, but I read it one minute after it's written. I may take a minute or two and reply at that time.

Also, I am awake and connected 24 hours a day, 7 days a week.

Jacquelita PM'ed me this shot just the other day...

lol
