- inactive, on 04/28/2009, -4/+32The last black hole I explored cost $40 and gave me clap
- Kuci06, on 04/27/2009, -1/+14Black Holes are awesome
- GraceHead, on 04/28/2009, -0/+8YOU WENT THERE!
- jmdwinter, on 04/28/2009, -0/+8Actually according to Hawking you would eventually evaporate trillions of years from now. So you and your loved one would eventually be spat out all over the universe :-P. (Sorry for being a buzzkill)
- inactive, on 04/28/2009, -0/+7yes?
- hearnada, on 04/28/2009, -2/+9I Would like to die this way. The person I loved and I would enter and brought together as close as could possibly be, for all eternity if they're right. That would be so awesome.
Side note I don't wanna die but that is just what is up. - anliath, on 04/28/2009, -0/+6well spent if you ask me
- Anth0n, on 04/28/2009, -0/+5Dugg for the Michael Jackson moonwalk analogy.
- oneoverzero, on 04/28/2009, -0/+5Even if the crazies are right and black holes are a gateway to another universe... that whole spaghettification thing will still happen first
- Quisquis, on 04/28/2009, -0/+4Pop-sci articles are usually full of misconceptions. General relativity has absolutely nothing to say about what happens when you get very near a black hole.
A perfect example: The article talks about falling faster than light... the website being refrenced: "All distortions of images are real, both general relativistic from the gravitational bending of light, and special relativistic from the near light speed orbit."

Like I said, the article is full of misconceptions and useless because of it. - Merrell0, on 04/28/2009, -0/+4Wrap before you tap or you'll get the clap. Also, don't have sex with animals.
- CrazySpaniard, on 04/28/2009, -0/+3I see what you did there
- jerstud56, on 04/28/2009, -1/+4Not all are pink. Some of them are brown on the inside.
- christoast, on 04/28/2009, -1/+4Tyson says it better.

Well yes but let me explain it like this, it's both possible and not possible to exceed the speed of light. It's all in relative terms.
Hear me out.
You can't take a space ship and fly just at any ol' random direction and fly faster then light, it's impossible. But what a spinning black hole does is, it's so dense and so heavy, when it spins, it's actually spinning the SPACE AND TIME around it. Imagine you have a cup of coffee, and you stir it, now if you wold drop something in it, it would spin around in the coffee all by itself even though IT ITSELF it's not moving.
It's kinda like this: let's say you are sitting in a train right? And it moves at 40mph, now if you stand up in that train section and walk forwards, it's almost as if you all of a sudden are moving 41mph innit? In the same sense, if you take a spaceship, fly very close around a spinning black hole even though you don't fly faster then the speed of light in "normal form", you ARE because because the spinning black hole is helping you out (like the coffee and the train analogy), so for you and me standing and watching from the sidelines it looks like the ship is going faster then the speed of light = travels back in time. The closer you get to the speed of light the faster in time you travel, when you pass the speed of light you travel BACK in times. If you've ever looked at a car wheel as it's starts to move from 0mph and it picks up speed, doesn't it look like when it reaches 20mph or whatever as if the wheel is turning BACKWARDS all of a sudden? In this case it's only an optic illusion but you get the point =)
Same thing when it sucks things towards it's singularity. It doesn't only suck things by itself towards it, it freaking sucks space and time itself towards it, thus technically sucking things in faster then the speed of light.
*breathes out* - WalkerTXclocker, on 04/28/2009, -0/+3The speed limit IN the universe is light. However the space he is talking about falling IS the universe not in it. It's kinda like the current theory of inflation has space expanding far faster than the speed of light because space is moving. anything in that space is restricted to the speed of light
- craeyon, on 04/28/2009, -3/+6I believe the word is spaghettification
- mrpunman, on 04/28/2009, -0/+3I don't think they realized the gravity of the situation here
- Rocketbird, on 04/28/2009, -0/+2This is one of the coolest articles I've ever read.
- jmdwinter, on 04/28/2009, -0/+2Then wouldn't a black hole be a collage of images of everything that's ever been sucked into it?
- Tddupre, on 04/28/2009, -0/+2cool story bro
- inactive, on 04/28/2009, -0/+2I would hope there would be something cool to see before being crushed infinitely small
- JoeHague, on 04/28/2009, -1/+3How can yo be so sure you would be dead?
- mattyboy555, on 04/28/2009, -4/+6Like a vagina?
- soccernamlak, on 04/28/2009, -0/+2Well, technically only observers at an infinite radius from the event horizon would be able to see you two frozen in space, although you both would be flattened across the black hole sphere. However, you and your love one would not notice anything going past the Schwarzschild radius and would be crushed and split into billions of particles due to the gravitational pressure inside of the black hole's radius.
It be a really painful, but quick, death. And as said above, your image and actual particles inside of the black hole would evaporate somewhere in the order of 10^70 years from now, give or take, because of Hawking Radiation resulting from particles in a vacuum splitting into electrons and positrons at the Schwarzschild radius and not being able to reform again. - RanIntoTheDevil, on 04/28/2009, -0/+2FTA: "The gravity at your feet is stronger than the gravity at your head, as long as you fall in feet first. ... You feel this difference in gravity between your feet and your head as a tidal force, which pulls you apart vertically in a process called 'spaghettification,' " Hamilton writes
- jmdwinter, on 04/28/2009, -0/+2I just shat my pants...
- JoeHague, on 04/28/2009, -0/+2You wouldn't evaporate, or be spit out all over the universe.... you would just cease to exist.
Hawking theorized that a black hole has non-zero temperature and entropy, therefore it emits thermal radiation. Because E=mc*2, when a black hole reaches a void- and no no new mater collapses into the singularity - it loses mass. Eventually no mass remains. - NUMBER4940, on 04/28/2009, -0/+2So, we can't see them directly, but...we see pictures of "them" surface on the internet fairly regularly, and now...a video?
Fascinating and interesting, but...what's next? Black hole soup for the soul? - cezx, on 04/28/2009, -0/+2haha, i learned this in astronomy 201 in my university :(
- seth553, on 04/28/2009, -0/+2Your life would end about as unceremoniously as that video did. Hopefully, at least, your British helmsman would be there to explain why you're not seeing a red grid in your final seconds.
- JoeHeavyFlow, on 04/28/2009, -0/+1Dugg for "spaghettification"
- craeyon, on 04/28/2009, -0/+1oh i didn't read the article. it just said vapourized so I thought I should correct it.
- bpeacock22, on 04/28/2009, -0/+1Spaghettification.
- mannajar, on 04/28/2009, -0/+1It is speculation to connect this to a black hole. The wiki article says that accretion disks might be evidence supporting the notion that black holes exist. IE- at the moment their existence is still purely theoretical.
I'll say it again: black holes are a glamorous fiction. - antsydrew, on 04/28/2009, -0/+1I am not a scientist, but I think the answer depends on what you mean by "time slow/down freeze for you." For you, looking at yourself, I think time would proceed normally. But if you were observing events in the distance, time would appear to speed UP. From anyone looking at you (or, rather at light based images of you traveling back to them), it would appear that time is slowing down for you.
Another way to look at it: photons, which travel at the speed of light, don't "age" at all, relative to the things they are moving away from.
I may be wrong about this, but it was my understanding that the central insight of relativity is that all objects in a given frame of reference travel at "the speed of light" in a sense: it's just a matter of what vector they are traveling in, and time is one of those possible vectors. Objects at rest appear to travel at the speed of light but ONLY in the dimension of time. Things like photons travel at the speed of light THROUGH SPACE (i.e. they aren't traveling in the dimension of time at all) Things that are moving away from you at sublight speeds have some of their movement in space, and some of it in time (but less of it in time than objects at rest, relative to you), and as they speed up, less and less of that movement is in time and more of it is in space. That's why anyone accelerating away from you would then appear not to age quite as quickly as you do (again, that's the case from YOUR frame of reference). - uptwolait, on 04/28/2009, -0/+1Livestock?
- honeybrass, on 04/28/2009, -0/+1Interestingly that is always wat I have thought, but have never seen anything to back that up. So contradiction in theory there maybe? Also if it is true that black holes never really stop forming, (http://www.wired.com/wiredscience/2007/06/a-soluti ... then the image of the original collapse should also still be present, though incredibly faint.
- kitchensj, on 04/29/2009, -0/+1Clever FAIL.
- JAVandiver, on 04/28/2009, -0/+1Easy as eating pancakes.
- JoeHague, on 04/28/2009, -0/+1Hawking's equation for the entropy for a black hole, "S = \frac{c^{3}kA}{4 \hbar G}" (which is as close to proven fact as the theory of relativity) and his theory for black hole evaporation in general do not satisfy the conservation of energy/mass.
This is commonly referred to as The Information Paradox.
The physics community in general has not come to terms yet on a solution for this issue, although theories have been published. Hawking himself contends that the missing information(matter/energy) is escaping into an alternate universe where black holes do not exist. According to him eventually all universes containing black holes will be gone from reality.
There is a small issue I have with this matter.
Physicist see Hawking Radiation as the stone cold fact- even though it is currently flying in the face of General Relativity. They cannot fathom the possibility that Hawking could be wrong, even though no physical evidence to this date has been produced to support the theory. The general consensus is that it just looks too good to be wrong. So remember the next time the physicist over at CERN tell us that particle accelerators are completely safe, their safety is based on a theory that they don't even completely understand. - inactive, on 04/29/2009, -0/+1You should see the one at the front! Its got folding...
- blowed247, on 04/28/2009, -3/+4that's what she said.
- inactive, on 07/04/2009, -0/+1And on an over-cast day the sky is completely white, so whacha gonna do about it willis
- honeybrass, on 04/28/2009, -0/+1not quite what he's talking about but true nonetheless.
- honeybrass, on 04/28/2009, -0/+1Thats not technically correct. You can fall "faster than the speed of light" towards a black hole because gravity is speeding up light, hence in relationship to the outside world you are also speeding up. You don't actually exceed the speed of light in your local area, just light itself gets faster. Actually from the point of view of an outside observer you would appear to stop forever.
- mmittimm, on 04/28/2009, -0/+1Welcome to digg. Enjoy your stay!
- Spo8, on 04/28/2009, -0/+1I've always wondered something.
If you theoretically get closer to and surpass the speed of light as you get pulled in past the event horizon, wouldn't time slow down/freeze for you as well, not just your image to the observer? My understanding of general relativity is extremely shaky at best.
Or does that law of matter and the speed of light no longer apply in the black hole's void? - jawabiscuit, on 04/28/2009, -0/+1Cause I fell in, a black hole, how could I know, that this would be my fate.
