do you people think that we will ever be able to create an engine powerful enough to counteract the force of a black hole so we might actually be able to go in and out as we please?

In short, no.
Remember, a black hole isn't truly a hole. It's a bunch of matter with so much gravitational attraction that it actually collapses in upon itself, creating an object of small size, but lots of gravity. There is nothing to go into except a massive crash. Correct me if I'm wrong, but I believe that in a black hole, the atomic structure of all matter collapses into a big jumble of random particles. The only reason it's called a hole is because you can't see it, reason being that it doesn't reflect light for obvious reasons.
There's really not a lot to explore.
Hmm... for those who have read Ender's Game... I wonder what would happen if we used an Dr. Device on a black hole?
(It's a play on acronyms. Dr. Device -> M.D. Device -> Molecular Disruption Device)
In the book, it's defined as a zone where two lasers meet in just the right way to change the atomic forces such that electrons can't be shared, causing the molecule to fly apart, effecting a chain reaction...
Assuming it is possible to do that, would the graviational effect of a black hole affect the beam? And would super-dense matter even react? Neutronium doesn't even HAVE electrons in it...
What if you swung another hypermassive mass around it at high speed? Could you "stretch" a pinpoint of collapsed space?
A black hole radiated energy due to the way it absorbs portions of spontaneously-produced particle-antiparticle pairs near the event horizon, resulting in X-ray emissions... So energy goes out, and mass goes in...
In a way, a black hole is a one-way total conversion machine. And you can starve them of matter, causing them to eventually shrink as they give off quanta... although I could be wrong.
accually a black hole in the sense think of space as a blanket, suspended in the air
now u place objects on that blanket lets say a marble now there would be a dent in the blanket where the marble sits ok
now if u were to place another object such as lets say a golf ball
now the golf ball weighs more than the marble so it would depress the blanket further than the marble now with that in mind envision a blanket, a big one in your living room to say cause having it out side would freak people out, suspended in the air with nothing holding it up basicly floating. now if you were to move the golf ball or the marble closer to each other
they would run into each other where the dents they make in the blanket overlap, basicly in a sense attract. think of them as planets
now if u were to take a shot put ball and put it on the blanket its heavey enough to pull the blanket yet not enough to rip it, and leave a big impression big enough that unless the golf ball and marble were far enough away they wouldnt run into it. think of the stot put as the black hole. this model i have created is to give u an idea of the concept.
now whith this in mind a black hole has enough of a gravitational pull not even light can escape so one would be skeptic of us ever obtaining the means to escape
knowing that light travels approx 186,000 miles per second.
also to help the marbleis more easily moved than lets say the golf ball and the shot putt
so the shot put is pretty much gonna stay where it lays so the golf ball has a lttle more mass than themarble so the marble is more likely the one to move more so than the golf ball the shot putt will most difinatly not move from its position. basicly the more mass u have the mor inclined you are to your position unless acted apon by an eaquall or greater force or depression in this case. as far as people know light is the fastest ting known to man, but if your into quantum physics or mechanics they believe that a force not understood is capable of
speeds many times faster than light. basicly its the charge that an atom has, has an opposite
like a twin but there opposite. so think of it like this you have 2 atoms that attract each other
if u change the charge of course 1 atom has a more positive charge and the other has a more negitive charge. if u were to change the charge of 1 the other similtaniously will respond with the opposite.
now they say that u can have these atoms in lets say different galaxys.
say it would take light 1000 years to travel the distance
but if u change the charge in the atom the other would respond intantaniously
no lag time meanwhile light would take its sweet time of 1000 years to get there.
so we are aware of this force if u will but are not even close to understanding it
also ther is dark matter in space but i wont even go there.
heres some food for thought you know when u turn ur tv on and change it to a station u cant recieve there that snow
well they say thats noise left over from the big bang!
CyberSpyder, if you can design a faster than light engine, then it might be possible. Light is the fastest thing that we've observed is unable to escape the gravitational pull of a black hole.
I'd recommend reading up on them at the following sites:

I doubt it. If you got stuck in one, you would see yourself coming in each time you passed around because you are going so fast it you travel backwards in time by a few seconds. However, there has been talk of wormholes that could transport someone across the universe. The problem is holding one open.
you are all wrong stop gettin your info from star trek
Actually, the theory is that you go FORWARD in time. It's based on Einstein's theory of relativity, which as has been said before in the general chit chat forum, is being seriously questioned right now. The wormhole theory is the same way. I doubt either are possible.
stflook, have you got a link to that? I mean, we're all headed forward in time right now regardless of whether or not we like it...
You know what I meant.
Anyway, the theory of relativity allows for such things as time travel, and rips in the space-time continuum. That's where that time travel theory came about. The artilce about the rival to the theory of relativity was in the general chit chat section a while ago. I'm too lazy to get the link for you.
Yeah, I could guess what you meant, but then again, travel forward in time by whose frame of reference? I suppose from your point of view, if you stopped in time and started up again, it would appear to you that you had skipped ahead in time...
So from whose point of view would you have jumped forward in time?
time travel has already happened...
russian cosmonaut who was up on mir is actually about 1/50th of a second ahead of everyone else...(or is that behind...can't remember...)...he spent something like 18 months in orbit zooming around at 17000 mph which was enough to have measurable relativistic consequences...not real exciting from a scifi point of view but...time travel nontheless
also...black hole, worm hole manipulation is theoretically possible...one simply needs a large enough amount of antigravity...gravity is your big foe when you're dealing with wormholes/blackholes...just conteract it with an antigrav field large enough to step through and voila...a portal through space...it's not out of the question to move the end of the wormhole in a manner as to alter the when and well as the where...
btw...given current technology..we could produce enough antigravity to hold open a stable wormhole...we'd just need a particle accelerator the size of the solar system to do it...
btw...i'm no expert...but i did read this months popular science...
http://www.popsci.com/popsci/contents/
"Let's Do the Time Warp Again
The science and the fiction of time travel are weird. But the science—courtesy of Einstein and others—is much weirder. "
i should have also mentioned that the theory that this is based on is that blackholes create such a distortion of space/time that they may in fact have other sides...that is...companion black holes somewhere else in space/time...which gives you the potential for blackholes to in fact be wormholes...you just need to stick your finger in and pry it open...
the article also suggests that rapidly spinning parallel cosmic strings could possibly be used as a time machine...(course they didn't mention how to find 2 parallel cosmic strings let alone get 2 of them to spin rapidly about... ;)
Obviously, it would be from the time-traveler's point of view.Quote:

By the way, I don't believe that theory is true. I see no relationship between velocity and time. Like I said before, it has been posted in the general chit chat section that the theory of relativity is under serious review. I think they're going to find it's flawed, if they haven't already.
Have you read about the cesium clock time dilation experiments? As far as time dilation is concerned, we have evidence that it is true.Quote:

BTW, I think General Relativity is probably no more flawed than Newton' laws of physics. It is based on observation, therefore as we are capable of observing more and more we're just updating what we know.
I guess but if he fails the time traveller might die or at least end up who where when or where.
I read about a study conducted by NASA and a few other space agencies that looked into this problem. All the geniuses involved decided that, yes, it would be possible but it would require something that resembles a "warpdrive" straight out of Startrek in order to travel significantly faster than the speed of light. They also concluded that this would, while theoretically, be possible would, also theoretically, require all the energy in the entire universe to run, which if ever built and operated would destroy the universe and everything in it including this "warpdrive".
So after years of study it was decided to leave time travel to future generations who, when we are all long dead and gone, could travel back to our "time" and using their wonderfully advanced technology prolong everybodys life so that we would never die.
Of coarse this would lead to a whole new problem of over crowding on this planet we call home, but thats a different matter to be worried about another "time". :D
(You don't get the joke, do you?)
Not so dramatical... You're talking about time dilation. Time dilation stuff can be found here: http://www.fourmilab.ch/cship/timedial.html . It's the well known thing that the faster you move the slower the time goes on (so the cosmonaut is at our point of view younger than he should be ;)).Quote:

BERBURT: Isn't that exactly about what they are talking about in the Teleportation thread (http://www.antionline.com/showthread...hreadid=218534)? You should take a look at it, too. And I think the interacting things are the quantum spins, not atoms'. A very fascinating thing, though.Quote:

I think we all should watch the Back to the Future -movies now again. :D
To all my learned compatriots - I believe I have found a real blackhole.
Isn't a general description a place where nothing that enters escapes and there is no light?
Voila. Our accounting department is one such place. Whole paper trails of companies have disappeared into its forbidding entrails. <I'm thinking of Sarlaac's pit in return of the jedi>
Why just the other day several staff members went to it never to be seen again....
