A+ was probably the easist exam.  I took a classroom based course.  I think it was put on by New Horizons?

Hawkings radiation is the radiation that a black hole gives off. It is why Black Holes have not become so big as to distroy everything.  It also is one of the things which might eventually lead to the combining of general relativity and Quantum Theory.

The scientist in charge of this project were taking extra care with picture preparation. Go to the site and you will see that around May 17th I think we can start looking for the particles from space.\nSee link below for Stardust at Home

Time magazine had an article or two in the past, don't remember the exact year, believe it was about '98-2000. SETI has a page where you can use your home pc to check radio data for signs of E.B.E.'s. Check major publications for such things: National Geographic, etc. Just google it.

I've heard some call black matter a blackhole. The honest truth is we just dont know. Its a theory nothing more. A human concept to TRY to understand something. \n\nLike the notion of "time". We measure that based on our small experiences within our solar system. For all we know there could be a larger, grander universal measurement.

It wasn't Hawking who came up with the theory, but at the core of a black hole is a body of super dense matter wherein even the space between the nucleus  of an atom and its electrons has been compressed into nothingness.\n\nImagine all the matter that composes a large cruise ship occupying a space less than the size of a tear-drop.\n\nAll still theory, though the evidence has gotten pretty convincing over the last 60 years.

a black hole is an area of space-time with a gravitational field so intense that its escape velocity is equal to or exceeds the speed of light.

Hey,\nThe WOW signal was recorded Aug 15th 1977 by Jerry Ehman. It was signal from space that was so strong that it pushed the Big Ear recording device off of the chart. SETI is a fun little project to keep an eye on. Write me an E-Mail if you find anything else out.\nkeptcompany@yahoo.com

Kentrell, I want you to look at this Nova website, and to watch these videos, OK?  I did, and was quite impressed with them.  they use infrared X-ray telescopes to look to the center of our Milky Way galaxy, with very clear images!!\n\nhttp://www.pbs.org/wgbh/nova/blackhole/program.html\n\nI believe you will like these, will learn from them!

Like all gravitationally-formed objects, a black hole is roughly spherical in shape (like planets and stars, a rotating black hole will be slightly flattened at the poles.)  According to Hawking's theory, black holes do emit radiation (and therefore mass) in accordance with quantum rules.  Theoretically, given enough time a black hole could radiate away enough of its mass to disappear completely.  When its mass drops below a certain critical threshhold, the remaining mass of the black hole would disappear in a final violent burst of gamma radiation.  Unfortunately (or perhaps fortunately) the best estimates we have for the time it would take for a black hole to explode in this way is far longer than the current estimated age of the universe, so it is not likely we would be able to test this theory through direct observation.

Black holes almost certainly exist. Wormholes almost certainly do not.

An event horizon is the theoretical visible edge of a black hole.  A black hole is a mass so dense that its gravity will allow nothing to escape, not even an object travelling at the speed of light, not even light itself.  An event horizon is the boundary of a black hole at which light can still escape.  Therefore we could see everything that happens up to an event horizon, in theory.  Beyond this boundary, light is drawn back into the super-dense mass and nothing can be seen.
