Human scientists mostly agree time started with thebig bang, and they mostly agree light is the fastest 'thing' measureable. They agree that time and light are connected. Via the big bang through its creation. They agree that no partical with rest mass can be moved to a speed greater than that of light in a vacuum. But are humans correct ? Putting all the actual science we have asside, thinking slightly outside the box of norm, what do you people think ? A poll for your enjoyment.

Technically FTL is possibly by the equations. The problem is lightspeed itself. If I remember the equation correctly, the closer you get to lightspeed the closer your mass comes to infinite, reaching this once you yourself hit lightspeed. aka barring acceleration.

The thing is, that the moment you get past the speed of light, your mass instead becomes negative and one would assume that you are able to accelerate once more with negative mass.

Not to mention that there are ways to get particles that move at the speed of light to get to 3xtimes or 4xtimes the speed.

No, this really isn't true at all.

They agree that no partical with rest mass can be moved to a speed greater than that of light in a vacuum.

particle, but yes, greater than or equal to. Also all massless particles travel at the speed of light when free.

Putting all the actual science we have asside,

Errr... yeah so if we just ignore science what is my opinion on a matter of science? Not a lot I guess. It would just be a guess, a stab in the dark without some attempt to test it.

and @Junk Angel - I imagine you're referring to the "negative square-root" behavior in the special relativity equations, or early-tachyonic behavior. There are other "equations" that actual do block this behavior. And even if it were to not be blocked, the behavior would not be to be "able to accelerate once more with negative mass", you would naturally accelerate away from the speed of light, much like things on this side of the line decelerate away from. But in anycase, this is just speculation on a behavior based on equations that specifically restrict that behavior, just thought you'd like to know :)

I would recommend having a look at "Faster than the speed of light" by Prof. Joao Magueijo, while the topic is more on "variable speed of light" it does give some ground level discussion to faster than light theories.

If you travel at light speed, you require an infinite ammount of energy. It just isn't possible. Yet.

From what we know it is not yet possible to accelerate normal matter to c and beyond.

However, being constrained by normal matter is becoming a thing of the past.

Ah I thought it was just the extended uh acceleration? Speed? No idea right now. Ah this seems to be it 8cb9e01a8eedc54c9b29c5b8f9629fa0.png Though looking at the wikki there seem to be two modern views, which we never did at physics. (Having a guy who thought future kindergarten uh teachers? is not good for physics :P)

The sciencey folks tell me it can't be done; I might be tempted to reply that the laws of physics are the same when measured from within any inertial frame of reference with respect to the measuring device. But since I don't have the years required, or any practical use, for an education in physics I just take it on faith that's not so and relativity holds.

IMHO I dont think we will ever develop FTL drives.

I do think it will be possible to build Jumpgates, something similar to a wormhole that possibly travels through a different dimension then re emerges in our space and time.

Yes it is possible. Just not now. If people put their differences aside and work toward a common goal like the advance of humanity then, it might happen a lot faster. But due to internal strife, it quite not possible now.;)
