Yes, it is possible.

No, light is not the fastest thing.

Gravity is faster.

Time is a measure made by man, not a tangible fact of the universe.

No, you can't create a time bubble.

Perhaps, a gravity bubble is possible.

A gravity bubble would hopefully be able to counter the effect of the extreme g-force on the people travelling at that speed.

does gravity exists out of particles? I mean, I thought it was a force. A force strong enough to hold us here

Hmmm... the speed of gravity. I think the particular attraction is constant, has been constant, and will be constant forever, so there is no way to see if there in fact is a speed of gravity... oh wait! Move supermassive object A on a tangent line 100000 miles from observation point B and see if gravity "keeps up"

As to balancing accelerations, ever read anything about the "balanced drive"? If not, I shall enlighten you

gravity is a force, how can it have a speed?

aaarrrghhhhhh! u astrophysical n00bs!

NOTHING can travel faster than light. any speculation about stuff that might, like tachyons, is exactly that, pure speculation. in fact, it's fiction! In our universe the speed of light is a constant, and a barrier that cannot be broken.

Folding space or warping is the only ftl theory that has any intellectual credence but it doesn't postulate travel faster than light, it just brings 2 points together at the same time, so it isn't actually travelling ftl. See the film Event Horizon for a decent explanation of this.

yes, the speed of light as calculated by Einstein and his contemporaries was somewhat inaccurate, modern technology corrected this value in the mid 60s, but general relativity remains, thank you very much.

Gravity is NOT faster than light. it is yet uncertain as to whether gravity is a force per se or merely an effect caused by mass in the space-time continuum. The attempts to bring together a unified field-theory are partly trying to prove that gravity is indeed a force like light, or x-rays, whatever. being able to quantify gravity as a force in this respect would solve a lot of mathematical problems in advanced astrophysics, unf. it (the purely theoretical particle called graviton) yet eludes mathematicians and physicists. plz remember that a lot of this stuff exists only as hypotheses that solve certain mathematical problems - that does not mean they actually do exist in nature.

Gravity can be so strong and overwhelming that it can overcome even the speed of light; that's what a black hole actually is, the intense gravity field of a singularity that is so powerful even light can't escape it so therefore u can't see anything that goes on inside this gravitational field, hence the term "event horizon." Black Holes are detected by the EM output of the stuff that falls into them as its getting ripped to bits B4 it reaches the event horizon; of themselves black holes are undetectable.

it might be possible to travel to another part of the universe or even another dimension using blackholes as gateways but u would have to enter one at virtually the speed of light, in which case relativity would already have taken it's toll on ur time, and u would have to be in an incredibly tough ship to withstand the tidal forces and radiation. u'd also have to go into a spinning one and via the poles, oh yeh, u'd have no idea where u'd end up even IF u survived, which u wouldn't, but to be fair u wouldn't know u were dying, because ur last moment would last forever, as far as u were concerned.

Time, like speed, is relative. Time cannot be altered, it flows one way, and to suggest u can slow down or speed up time is fallacious. u can however affect the PERCEPTION of time. travel near enough to the speed of light and for u time slows down, for an external observer and the rest of the univers the experience of time remains the same. I love the ideas of travelling though time, but unf. any real time travellers will be heading on a one way trip to the future via space podule.

so take it as read. No FTL, no time travel, can't be done, makes for great sf though.

so taw you're saying that either warp travel or going through a worm hole would be the only viable solution to travel to other systems

"Make it so Number One"
Captain Picard 'Star Trek the Next Generation'

in theory, yes. again both are dependent upon technologies that do not exist except as hypotheses, folding or warping space so that two separate points become co-existent in time and space, or being able to detect such (and fly into it.) Viable? if so, not for a long long time. Star Trek does it with a warp shell powered by a matter-antimatter reaction, Event Horizon did it with an artificial black hole, again purely theoretical technologies. as of yet in reality we can't even successfully control a fusion reaction for more than a few seconds. maybe it will come one day.

their r black holes with lower gravitation with are redshifted... speed off light isn't the same always... u can bend light and even make a rainbow of it... red light is the fasted, so that's why some "black holes" r redshifted, and have a lot off x-rays coming out also with that red light... so u can detect some black holes, not all...

this is only possible by a black hole what wasn't a sun before, but a worm hole... but then still... the gravitation will rip u apart... and escaping is impossible, co'z u need to go faster then light... a wormhole is made by time-bending... a black hole maded from a starved sun is that heavy that it bend spacetime... so how can u c the div between a black hole and a socalled wormhole... a wormhole have only no gravitation... so how it can bend time it's impossible to tell how a worm hole is maded or come and go, theirfor u need to know what time is and what u can do with it...

---

how to get faster then light

---

worm holes... maybe the only solution...

---

Star Trek does it with a warp shell powered by a matter-antimatter reaction, Event Horizon did it with an artificial black hole

---

the anti-matter reactor... nice, but the only place where that reactor will work well, is by a gravitation what can bend light, so called artificial black hole from the Event Horizon... what, antimatter reactor is a artificial black hole, but yes... otherwhise u can't made anti-matter and matter otherwhise the maded matter and anti-matter will go back to eachother and disapeare again ...

---

how to get faster then light

---

an other solution... time-bending
if u fly 300 m/s (like in freelancer) and gonna speed up the time outside and leave the time inside the ship the same (bending time), then u go 600 m/s...

if u do the same 100 times bigger then u will go 30.000, 1/10 of LS (light speed)... then ur will have still 40 years to go to the closest star from our sun...

if ur able to do this... u need also to get slow down time to 1/1 outside/inside ship... otherwhise u can't slow the reaction down... and if this works, maybe u can go from here to the otherside off the universe in a split second...

but for 300m/s to speed of light their must be a great div... outedial/interial time must be 1000/1, that for only get by the speed of light... then going faster then light... so i think u need also by this a anti-matter reactor (yup... also called artificial black hole, for it enormous gravital shift inside, for not getting thus material getting back to eachother where the engine needs to drive with)...

but well... i think this is the solution what will made later in time

If u c some1 in a dagger make fireballs from hunters it can be me

Oh god, here come the long posts again...

ah, speculative astrophysics, dontcha just love it?

Gravity moves in waves.

Gravity IS faster than light.

Sound moves in waves as does radio, which both can be measured for speed.

Tests to send messages using gravity waves are being conducted right now.

It is believed that it would take 3 minutes to cross a galaxy with a gravity signal.

Thus it moves at a very high speed, but is not instantaneous.

As for light and gravity:

Light is particles and waves, very peculiar as there is nothing else like it.

Gravity is suspected to be force and waves, very peculiar as there is nothing else like it.

If one thing can go faster than light, then it is possible for anything to do it.

@Taw - Yes!

red light is the fasted, so that's why some "black holes" r redshifted, and ...

---

Blue/red shift is/are caused by an object traveing (or is it accelerating) quiute fast toward/away from you. Tward you, and the light waves are compressed, making them a higher frequency and thus thier color is shifter toward blue... blue shift. Opposite with red. It's similer to the compresion of sound waves.

Einstien left a little technicality in all his theroys... no matter can accelerate to light speed. So, any particle that is somehow inherantly FTL is plausable to me. This could be achieved on a spacecraft, but would require instant speed schage from sublight to FTL speed... infinite acceleration. So all we need to do is figure that out....

Heh heh... my sig is apropriate, no?

no no no no it is NOT possible to travel faster than light, ye cannae brek the laws o' physics, cap'n. the concept (and it is only a concept) of folding or warping space or using wormholes (which are purely theoretical postulates of superstring theory) gets around this but doesn't break any physical laws as such - in theory.

@sS, how can anyone send a signal using gravity waves when the existence of a gravity wave or particle is still only a mathematical hypothesis? where did u get this information from? anyway light travels in quanta (packets) and yes I agree at the quantum and sub-atomic level, things like photons behave very very strangely indeed, not at all in accordance with what relativity predicts is supposed to happen; hence the search for a unified field theorem which is supposed to bring together the diverse and often contradictory schools of Relativity and Quantum together. We'll just see about that.

@WB, infinite acceleration is impossible. there is absolutley no way past the lightspeed barrier. as u approach infinitesmally close the lightspeed, time (for u) slows down to such a degree that u will never ever reach lightspeed. this is the crux of the general theory of relativity, and also one of those wonderful paradoxes.

in Dune there was no need for any technology or hyperdive boxes living under the dashboard of ur space podule, the Guild Navigators did it by spice-induced self-telekinesis "travelling.. without moving" much more elegant, don't u think?

Yes. That was rather nice. But now the God emperor is dead so what will happen to his spice horde??! Shai Halud must be allowed to return, or the melange will be gone forever and mankind will be paralized in thier little self-worlds . But perhaps this Ixan device will solve the problem.
