Travelling into the past is most likely impossible. Causality (the relationship between cause and effect) will most likely prevent time travel into the past, as well as the second law of thermodynamics, the law of entropy, unless matter returns to original state, which, of course, defeats the purpose of travelling back in time. Paradoxes also prevent time travel (unless the multiverse exists).
The theory of relativity only allows for time travel, but it is still most likely realistically impossible (anyone here able to propose a way to travel into the past?). There is a small chance that the theories of relativity could be wrong because they are based around the speed of light being constant, and there is a chance that the speed of light isnt constant (over extremely long distances). Although parts of the theory of relativity have been proven (such as time dilation).
Although if you travelled through a Kerr-Black hole your particles may see another universe after you're crushed at the singularity.
The multiverse could possible exist although common sense rebels. This could have disturbing effects on the metaphysics of identity if there are an infinite number of characters that exist.
Ender, you should have known this, but anyway, according to the special theory of relativity it is IMPOSSIBLE to travel at the speed of light (in a vacuum), as your mass would be infinite, your length would have contracted to 0 and time would have dilated to a stop. Not to mention it would require an infinite amount of energy to reach it (which is impossible).
Travelling into the future is easy: If you travelled at 0.99999999c (c = Speed of light in a vacuum) you could travel to andromeda (the closest galaxy to us) and back in 55 years, but the Earth would have aged 4.7 billion years (if it still existed). Although travelling at those speeds, a single particle of dust would have the inertia of a planet.
And wormholes most likely exist on the plank scale forming a space time foam. You don't "make" wormholes. They already exist. All that stands in the way of travelling through wormholes are that they are really small (they can be enlarged with a lozenge that has the density of a nuetron star) and that they pinch off as soon as matter enters them (which can be solved by surrounding the "ship"with antimatter).

The faster an object’s velocity the slower time moves for that object. The problem for us is that mass increases as velocity does (mass and velocity are directly related). As well, the larger the mass, the more energy required to move said object.

…hasn’t been proven, it’s beyond our current means, but it has been proven that velocity and mass are directly proportional, where as velocity and time are in-directly proportional…

Um, isn’t that what I said? I aggree it is a problem, lol, I not going to expend anymore time defending myself or typos from people that don’t care to read the entire thread. You show knowledge in the topic, and I respect greatly your contribution to this thread, for the topic is a religion to me in itself, but you lose my appreciation for your comment directed individually.
Here is a speech on the topic ( Black Holes ) from Steven Hawking, It was 34 MB, but I reduced it to 64bit, the zip is 17 MB.
You must find your own answer, I do not hold it.
I will not keep this ZIP at this location for long, 1st come 1st serve.
ENJOY!

oh, i was just wondering why you didn't mention to anybody that travelling at c was impossible as they were all talking about travelling at c (and you seem to have a pretty good knowledge of the theory of relativity)

This is intriguing!
No-one can do the impossible, quite ture, however, I like to keep a positive frame of mind that, anything is possible, same thing. "Frame of mind..."

well , that was a point that i had already covered and thats is why i said that the "worm hole " would have to be the way to go, as far as space travel.
ok, so far from what i have found out about these types Lorentzian wormholes, is that they are made up of "exotic matter" stuff that is repelled by gravity, rather than attracted by it. this exotic matter has less energy than a pure vacuum.
what i was reading also went on to say that time-dependent wormholes actually have two throats, one for each direction of traffic.witch would make it possable for the time traveler to return form where he came, by useing the same worm hole.
now even if this types of worm hole could be used for travel so would still have to get to them first , right ?

well, there were also talking about making them too. the problem is finding enough of the "exotic matter" to do it . but hey, there working on it aleast. that should give us some hope .

IM SORRY GUYS!! That I dint get here before taxims and never had the chance to fill your mind up with useless knowledge on the strangest thing that have nothing to do with life.... :rolleyes: I had a problem with this topic only... something was keeping me out for a reason WELL NOW IM IN MUHAHAHA
So after skimming the last topic I see your talking about black holes. That just happen to be one of the most mysteries things in the universe thus my knowledge in them is vast. There are 3 main types of black holes one is the normal one with a non spinning center, the 2nd is one with a spinning center known as a singularity and the 3rd which is thought to be unexciting and only in theory a black hole that deifies every law in space and time call a naked singularity.
Before we start I want to go over some simple black hole physics, (all in theory) first when an object falls into a black hole it is striped of its chemical composition but its mass stays the same. Also is it highly probable, if the theory of time travel or dimensional travel is true, that you will not fall though the dead center and become part of the mass, also the spigetyfication (don’t have a frickin clue how to spell it) effect will also kill you almost instantly with out and infinitely powerfully gravity shield around you, spigetyfication is a process caused by more gravity closer to the black hole then farther away, as for all objects, and it pulls your feet harder then your head causing you to be pulled apart, slowly. Also to travel though time you have to travel though the infinitely small center of the black hole, which is kind of hard to do.
First the one with a non-spinning center. These are most common and are most powerful due to its stability. These types of black hole are also the ones that have the high velocity disk around it and the jets of ionized particles at its poles. There is (in highly probable theory) one in the center of our galaxy surrounded by the numerous stars which form the massive bulge in the center of the galaxy and which helps for the gravitational pull that keeps every thing in a steady rotation.
Now onto the2nd type, not much different from the first but it less common and the neutron star was spinning erratically around an invisible fulcrum causing the center to become a singularity which is simply a revolving center that causes an infinitely dense circle, now a circle in impossible in real life because it is infinitely thin as like any 2D object thus can exist any where but as a singularity. Which leads us to our next black hole.
Naked singularities are just singularities that have been striped of their outer mass, most uncommon and due to the conditions required to make it is impossible, but then again black hole are impossible. Naked singularities literally have the power to destroy the universe by decomposing mater to nothing, also impossible, and/or creating new mater erratically. Naked singularities also have the tendency to warp space into a VISIBALE foamy substance around its ring that would look kind of like that foam calk but with lots of nooks are crannies and constantly changing.
Just to make one thing clear, all this info was from me right now so some exact details may be flawed buy the concept, I assure you, is true.

ok then, if you say there are only three types of black holes, then how would you classify this Lorentzian wormhole , a black hole produced by a 'vacuum' phenomenon, with exotic geometry where time and space switch their roles, seemingly made up by the most part with this this exotic matter that has less energy than a pure vacuum? with out that hugh mass found in the the three you disscribed
is this not a black hole ?.

Ok the thing with the "lower then a vacuum" black hole your talking about I’m not that educated on....  well anyway I would classify as a black hole, a black hole draws thing in with a gravitational pull. A vacuum like that would be caused by created by the numerous particles flying around in out universe such as the neutrino which has no mass no volume and no chemical make up so really it cant happen but they do exist and in theory in a large enough number can push an object a few millimeters though time, which is enough to make something disappear (Bermuda triangle and other areas on earth)
With this 0 energy particles there could possibly negative energy particles and maybe out elusive "dark matter" is actually a negative energy particle, I assume you all know what dark matter is, if not, its a "cloud" that seems to act like a black hole and it severely bends light and sucks it up in the actual cloud. Thus we have your non black hole negative energies.
In theory black hole do die out when there fuel runs out. Although a black hole remnants might remain and suck up any thing that comes near it, a diskless black hole. But also in theory black holes are the natural universe reseters, in which the universe slowly becomes saturated with black holes, and the universe shrinks and is reborn in a "big bang" theory.
EDIT: GunRun I believe with reasonable theory that you can destroy a black hole with a an opposite equal reactive gravitational force which would end up detonation the black hole sending all it contents to normal density into space, with would in case all objects within the blast radius like a gigantic piece of pop corn. Also since when an object is sucked into a black hole it loses every thing but its mass structure, its possible you could be releasing energy beyond comprehension, AKA the end of the universe and many universe connected to other black holes (the multivers theory)

Cosmic Strings
Yet another theory for how we might travel back and forth through time uses the idea of cosmic strings, proposed by Princeton physicist J. Richard Gott in 1991. These are -- as their name suggests -- string-like objects that some scientists believe were formed in the early universe. These strings may line the entire length of the universe and are under immense pressure -- millions upon millions of tons.
These cosmic strings, which are thinner than an atom, would generate an enormous amount of gravitational pull on any objects that pass near them. Objects attached to a cosmic string could travel at incredible speeds, and because their gravitational force distorts spacetime, they could be used for time travel. By pulling two cosmic strings close together, or one string close to a black hole, it might be possible to warp spacetime enough to create closed time-like curves.
A spacecraft could be turned into a time machine by using the gravity produced by the two cosmic strings, or the string and black hole, to propel itself into the past. To do this, it would loop around the cosmic strings. However, there is still much speculation as to whether these strings exist, and if they do, in what form. Gott himself said that in order to travel back in time even one year, it would take a loop of string that contained half the mass-energy of an entire galaxy. And, as with any time machine, you couldn't go back farther than the point at which the time machine was created.
