I disagree. Black holes do exist. Just look in Michael Schiavo's eyes.

Sounds like someone is picking a fight with the guy in a wheelchair...only in this case, the guy is Stephen Hawking. When in doubt, bet on Hawking.

It has always seemed to me that humans (being a part of the universe) cannot understand the whole. It's like try to catch a shadow.

This is wrong.

Dark energy is an expansive, repulsory effect. This would negate the effects of a collapsing star if there was some sort of "transition"

What if Einstein had math anxiety? Would black holes be discovered earlier?

[billorites]

It's black and it looks like a hole. I guess it's a black hole.

I am so glad to hear this because I have been VERY worried. <;9//>

"When in doubt, bet on Hawking."

Except that Hawking lost his last bet (3rd paragraph of linked article below):

Oops. Sorry. The title search function seems to be a little, uh, unreliable.

In general relativity, there is no such thing as a 'universal time' that makes clocks tick at the same rate everywhere. Instead, gravity makes clocks run at different rates in different places. But quantum mechanics, which describes physical phenomena at infinitesimally small scales, is meaningful only if time is universal; if not, its equations make no sense.

I disagree. Different velocities with respect to other inertial frames makes clocks appear to run at different rates when viewed from different reference frames. Location has nothing to do with it, except when the location places one frame under an acceleration with respect to another. Then it is not the location, per se, but the proximity to some other influence.

If the author screwed this up so badly, can we really trust his conclusions?

Black holes are staples of science fiction...

...Poppycock! I saw one run for the presidency not a year ago, and his name was Rev. Al Sharpton.

there is a bad sex joke in here somewhere.........ahhh never mind

Next thing you know they'll be telling us that manmade global warming doesn't exist (sarcasm ended).

I don't know why, but I just love this stuff. The space time continuum stuff and the infinite event horizon without black holes makes Star Trek much more plausible.
