Have to be, trust me. If black hole has the mass smaller than ~Mount Everest, it'll evaporate before it can become dangerous. And AFAIK we can't accelerate such mass in particle accelerator.

They'll be trying to create mini-black holes (~1 Tev) at CERN's Large Hadron Collider. The idea is to study black hole evaporation via Hawking radiation.
LHC is due to go online in 2007.

Anyone read Paul Hogans "Thrice upon a time"?
If there's artificial intelligence, there's bound to be some artificial stupidity.

Yup.

btw, if you want to help LHC:
Unfortunatelly they don't accept new accounts right now...but I can supply you with details of mine!

Ahrm.
I meant MASS, not DENSITY.The Internet - where men are men, women are men, and teenage girls are FBI agents!

Even given that, a black hole of X mass placed into a solar orbit wouldn't necessarily affect the rest of the solar system any more than "normal" matter of the same mass.
The main effects would be the gravitational perturbation of planetary/object orbits, and this effect is still subject to the inverse square law, or whatever radiation is given off by its acretion disc if/when something starts to fell in.
FYI you and everyone else is orbiting a black hole of millions of solar masses as we speak. Most galaxies have a supermassive black hole at their core, which is why most of the matter in said galaxy started clumping to begin with.

Dammit, I was halfway through a response to your original message. :-pOriginally posted by GurmComment

Our sun can't become a black hole. :-pOriginally posted by Technoid
But I see your point.
But couldn't it be? As the black hole traveled through our ss, it would undoubtedly collect mass and become stronger. A star on the other hand, wouldn't...A black hole travelling through a solar system wouldn’t be anymore dangerous than a sun or planet in the same mass category....Comment

Uhmm...why not? Only mass matters when it comes to gravity...doesn't make a difference if it's concetrated in one point like the black hole or has the form of star of main (something
)...

Wouldn't a star burn some things off, etc, where a black hole would "absorb" it?Comment
-
No. Yeah, there is solar wind in case of normal star, but it's almost negligible in case of anything other than...solar sails
Furthermore the biggest problem with ANY object the mass of Sun through our system isn't that it would suck/absorb much - it would literally rip our system apart. Li-te-ra-lly. (planets flying out into deep space and such)
edit: Kooldino, try this app with the parameters below - not a bad approximation of Solar-mass body passing through Solar System IMHO.Last edited by Nowhere; 13 July 2005, 09:04. Comment
