The Most Distant Galaxies Yet Found

Using the 10-meter Keck telescope on Mauna Kea, astronomers will shortly report the most distant galaxies yet detected. They were detectable only by gravitational lensing from a foreground galaxy. These 6 galaxies were fully formed only 500 million years after the Big Bang. At this time they were already forming stars. Present theories of galaxy formation can not explain the formation of galaxies so early.

Every galaxy yet found contains at its centre a massive Black Hole. Galaxies formed around these objects like whirlpools around a drain. Primordial Black Holes have been predicted by Stephen Hawking and many physicists. A Universe of evidence tells us that supermassive Black Holes are primordial, formed shortly after the Big Bang.

PBH's are predicted to have formed from quantum fluctuations shortly after the Big Bang. Their size would be limited by a "horizon distance," that light could travel in a given time. Previously it was thought that the speed of light would cause any PBH's to be tiny. Discovery of galaxies fully formed soon after the Big Bang is still more evidence of a changing speed of light.

If supermassive black holes are primordial,wouldn't they have to evaporate at this moment?

Apropos of nothing I enjoy your blog which I stumbled across. I ran across this poem tonight and thought I'd share it as it seems relevant and maybe entertaining. It is by Su Tung-p'o.

Traveling at night and looking at the stars

Heaven high above, the night air chill,
ranged stars crowd the sky, all in proper places,
big stars darting rays back and forth,
little stars busy as boiling water.
Heaven and humans don't meddle with one another —
what does Heaven do anyway? —
but it's our habit to insist on pointing at things
and one by one assigning them names.
Southern Sieve, Northern Dipper —
what are these but household utensils?
What would Heaven do with their like?
We're the ones who decided to call them that.
Peer at things up close and you may learn their true form,
but guessed at from afar, they seem like something else.
Vastness such as this is beyond comprehension —
all I can do is sigh in endless wonder.

— Su Tung-p'o (1060 C.E.)

Thank you both. Previously it was thought that any Primordial Black Holes would be tiny, and subject to evaportion. Supermassive Black Holes can last indefinitely.

I think I got your point.If the speed of light is changing,the same is for a size of a blackhole,which is Shwartzchild radius,which depends on speed of light.So if the speed of light is getting smaller,the Shwartzchild radius is gettind bigger,so the evaporation is stopped

I've been thinking in this fact, and I think we're just ants in the Universe using Viagra Online We need more time to reflexing. But, I would like to thank you for the efforts you have made in writing this article.

They cant explain it because the theory is not right, I think that the age of the Universe is far older from what they say, for me the Universe has always existed.
They always think of things as impossible to later say that it is possible, scientists are just not open minded to think of the possibility of impossibles as possibles.
