[citation][nom]Gin Fushicho[/nom]A Wormhole is a bend in space and time. a Blackhole just sucks everything up with it's powerful gravity and condenses it into a tiny spot, kinda like a garbage compactor. Sp, Black holes don't go anywhere, they just kill you.[/citation]
umm... though I don't think Wiki = correct information 100% of the time... but if you are interested.. there is one on the wiki about the wormhole.
here is the "short" qourt:
" "maximally extended" refers to the idea that the spacetime should not have any "edges": for any possible trajectory of a free-falling particle (following a geodesic) in the spacetime, it should be possible to continue this path arbitrarily far into the particle's future or past, unless the trajectory hits a gravitational singularity like the one at the center of the black hole's interior. In order to satisfy this requirement, it turns out that in addition to the black hole interior region which particles enter when they fall through the event horizon from the outside, there must be a separate white hole interior region "
Of course these are all theory... but still..... Enjoy
[citation][nom]SevenVirtues[/nom]Oh and to be technical, we have hundreds of pictures of alien planets, Mars, Venus etc.You mean first picture of a planet outside our solar system.Man I'm such a dick lol.[/citation]
That was the first thing I thought.
Wormholes wont work because all matter that passes through them is rearranged. It is mathematically possible to fold space to allow FTL travel, as a physicist in Mexico recently proved, if you have a big enough energy source.
[citation][nom]dragonsqrrl[/nom]I'm guessing a planet that's "eight times the mass of Jupiter" will have a lot more then 3-4 times Earths gravity, especially since Jupiter is already a lot more then that.[/citation]
I think that depends on the radius and the rotation of the planet if we're talking about someone standing on the surface and getting crushed. Besides gas giants don't have a "surface", they just get denser and denser from the upper atmosphere on down.
[citation][nom]nforce4max[/nom]Interesting, they can image this far away planet and yet all they can manage to get of Pluto is some fuzzy images.[/citation]
That's because Pluto is incredibly dim. This planet is far more luminous than pluto. It's about a million times more massive and far far hotter.
As spore said and as his link states, this is *not* the first direct image of an extrasolar planet. It is, however, the first direct image of an extra solar planet orbiting a sunlike star taken from a ground based observatory.
One of my friends is at Mauna Kea right now actually. Observational astronomers get to go to all the cool places.
[citation][nom]SevenVirtues[/nom]at the end of the day the planet could be just like earth. 90% of things we are taught about space, distant planets, black holes etc. is all guess work.[/citation]
No it can't be just like earth, a planet 8 times the mass of Jupiter cannot develop the way earth has with breathable air, mountain ranges, seas etc. it is likely to be a gas giant. Also, most of the stuff we know about space, planets, black holes etc. are based on concrete science, not guesswork.
