Re: Is it possible to creat a black hole in a experiment room?

Dear Luke,

It is not possible to create a real black hole in a laboratory on
Earth.  The energy required to create a black hole is far beyond
anything that scientists can generate.  Even our Sun, which dwarfs the
Earth both in size and in energy production will not give rise to a
black hole at the end of its life.  Black holes are created when stars
larger than our Sun collapse, or at the centers of galaxies of
billions of stars, or during the Big Bang, all processes involving
unimaginably high energies.  Naturally, a "black hole weapon" is also
impossible at this time.

To answer the second part of your question in detail, I would need to
see the article to which you refer.  Using a WWWeb search engine, I
found several like this one, which I will take to be typical:
 http://www.sciencenet.org.uk/slup/CuttingEdge/Jan01/blackhole.html

The scientists in the link above are not creating real black holes,
but merely laboratory experiments that model one particular feature of
black holes, their ability to trap light.  Light or anything else can
enter the event horizon surrounding a black hole but can never escape.
The scientists hope that observing a similar effect in moving fluids,
rather than just imagining what actually occurs near a real black
hole, will stimulate new theoretical ideas which may prove useful for
real black holes.  Sometimes seeing a working model gives one insight
that equations on paper do not.
