Ha! If we all die, beer's on Fnord.

I'll take that bet. What do you put up if we don't?

Who know this could be the begining or the end, if this does not turn earth into a black hole maybe we will have advanced energy technology, maybe this could lead to space travel. So we might then go out and kill ourselves by starting a war with aliens.

If there were aliens, I think most would just be animal-like rather than bothering to invent stuff.

So, no end of the world? :x

I've got a badly stored bottle of table wine which it would take a brush with the end of the universe to make palatable...

We got a wonderful local brew here in the northwest US called Blue Boar, which brings to mind...

So iamnotaparakeet, you ran the math based on a black hole with a one meter diameter event horizon as I recall. Actually, I think it's irrelevant to talk about the diameter of an event horizon, because how do you determine how far it is from one side to the other through all that curved space inside, but I know what you mean.

Anyway, do you know if there's a lower size limit on the size of a black hole before it instantly dissolves because of Hawking radiation, like it wouldn't be around long enough to eat the earth?

A black hole with an event horizon say, one millimeter in diameter, would encounter matter as solid, or even one much smaller, a hundredth that size, would do the same.

That would be easier for them to make, but I believe you were talking about 52 orders of magnitude. Maybe not.

I've never been to Europe, but maybe Europe will come to me.

Yesterday I made a similar post, and it still stands. :wink:

For those 5 posters, I have an tube of M&M's Minis full of change that I'll divide among you. If the world does end. :)

Most of them yes but what if some had even been influenced by technology on there planet left behind by a space fairing species that mysterously disapeard. Or there could be some huge politcal network of galactic alien governments, which base is a huge space station which was presumabley made by some past species which also myserously disapeard. If you did not know both of these are part of stories in video games. hmm I wonder if I should start quoting all the movies now. In a lot of most scifis there requirs some stream of energy to go into hyperspace/slipspace/jumps/etc.

10 kilometers is supposed to be a reasonable size radius, but I don't know the lower limit for their existence. If it were only based on density, there would be no size limit. However, the amount of mass determines the gravitational potential, so you aren't going to have a lightweight blackhole, though it may be a single point.

most? I don't know, I mean, I think it could be, that some planets would be like that if we find life in other planets, but most? are we that special?

According to evolutionary timescale, how often has a technological species come about supposedly?

The other large brained animals have more sense.

That's why God gave us Wikipedia.

t is believed that the smallest mass a black hole could have without quantum effects eliminating any such description is of the order of the Planck mass, which is about 2 × 10−8 kg or 1.1 × 1019 GeV/c2. At this scale the black hole thermodynamic formulae predict the mini-black hole would have an entropy of only 4π nats; a Hawking temperature of TP / 8π, requiring thermal energy quanta comparable in energy to almost the mass of the entire mini black hole; and a Compton wavelength equal to the black hole's Schwarzschild radius (this distance being equal to the Planck length). This is the point where a classical gravitational description of the object stops being retrievable with merely small quantum corrections, but in effect completely breaks down.

Well how old is the universe, and respectivly how old is the earth, if there is an old one they must know how to sustain themselves, they may not even want us to compete with them. Also other planets could be hugely different to us that we can not curently fathom them, who know what others could do. There could be some that look so strange without any motions at all that make us look like savage animals in comparison run by instincts.

Cool, that's not very big. So maybe they still can make one. I was starting to get discouraged.
