Stephen Hawking

This is off the subject, but I have to vent!

Stephen Hawking gave a lecture in Portland Oregon last night.
Wow! Just being in the same room and seeing the genius in
his eyes was worth the price of admission. He is amazing!

If you ever get a chance to see him... do it! You won't be sorry.

If I sound like a babbling school girl, I'm sorry!

Cool :) What was the lecture on ?

I'm sure its off topic nature wont trouble anyone..

we aren't talking about much atm.. in Seti..

:)

'Brane New World' was the title of the lecture.

He talked about the theory of everything. Which Would have to include at least six dimensions beyond the four that we see as length, width, height and time.

He suggested that instead of the Universe being a flat plane, that the Universe is actually curved. The analogy that he gave was that of a balloon with all the galaxies painted on the surface,
as the balloon is inflated(big bang) the galaxies become farther apart. The surface of the balloon is the brane. The extra dimesions are contained within the brane. Black holes are the portals to the inner dimensions and therefore the other side of the universe.

However, contrary to popular belief, black holes emit radiation,
known as Hawking Radiation. They are actually evaporating.
He said that if a black hole was to appear next to our galaxy,
rather than us being sucked in, the black hole would evaporate and he would be awarded the Nobel Prize.

If a space craft where to approach a black hole, the gravity of the hole would probably crush it before it could enter.

[Supp]

Yes, gravity would reduce it to particles

and according to Theory of Relativity,
it would never reach center of b.h. even if it hadn't been crushed - it would stop on Schwartzschilds (or whoever...) radius and remain there forever.

in other words dont F*ck with black holes they 0wnz j00 :D

If a space craft where to approach a black hole, the gravity of the hole would probably crush it before it could enter.

The pilots would experience time differently before the craft was ripped apart. They would live out thier whole lives in a nanosecond, and then the tides would rip the ship and them apart. I wonder if they would come out the other side and get reassembled?

Nah...

When I was young, I attended a lecture given by Mr. Billions and Billions. He was VERY entertaining.

May all your quarks be charmed.

it would never reach center of b.h. even if it hadn't been crushed - it would stop on Schwartzschilds (or whoever...) radius and remain there forever.

The Event Horizon is simply the point of no return where material that passes it cannot get out of the gravity well without many state changes:)

Actually the Event Horizon does allow movement in both directions.

Falling material passes and enters the singularity,

Then the high energy particles created by the falling material escape the Event Horizon and appear to our telescopes as X-Rays.

whoa! dr colinT :D tell me a story sir :D whered u learn ur physics?

[ColinT]

Twelve years ago I needed to know something. I figured the answer would be found in Physics, so I took courses. Eventually I found the answer in Chemistry. I've been making a living on that simple answer ever since:)

And my background as a Hard Sci-Fi fan for the last 40 years helped a lot with the question above.

[Alpha_7]

Very interesting :))

[rosyboa]

I think that a question and answer session between Hawking and ColinT would be awesome...:thumbs:

[Alpha_7]

Dr Colin T Question Time...

Starring S. Hawking

[rosyboa]

Colin T,

What was the question that Physics couldn't answer but Chemistry could?

[Alpha_7]

Yeah I would be interested in knowing the answer to that one too.. :)

[dragongoddess]

Must disagree on the tearing up quote. I think the size , shape and rotation of the ship may have more to do with what happens then is usually accepted.:thumbs:

[mr_mann]

well the size of the ship would REALLY matter...

a ship being torn apart.. who knows what a different amount of partical mass would do to a black hole...

[rosyboa]

Art Bell said that Hawking is wrong!

He said that aliens from "Area 51," now located at center earth via the north pole, are responsible for black holes.

I for one believe him...

Fact: We are from Mars.

Don't believe me?

Talk to Richard C Hoagland.
