Will we see FTL travel in our life time?

Wouldn't it just be like white holes? Instead of taking in matter, it would push it out: so, in that way, its the opposite of an opposite.

Except that a white hole is a source of matter (I think- that has always confused me) while this is a piece of matter.

I highly doubt it.

I hope so.

If I had one wish I think it would be to have a time machine, to at least go back in time I guess.

to erase your existance? jus messin... no I was thinking though the only way would be the star trek method of travel..I read how that works once...but then again 2012 we might discover a new dimension or two eh?..lol

The easiest way to grasp this may be the spacetime rubber sheet analogy, where positive mass produces a "well" in spacetime, and negative mass produces a "hill" (a "well" from the other side of the sheet).

I think the only evolution in travel that i will see in my lifetime is in magnetism. This, however, is a big if. We could very easily be achieving speeds of up to 3000 MPH in mag rails. There is also evidence to prove that we can utilize magnetism as an energy source in automobiles. Our societies do not strive to better ourselves but to better our societies financial wealth. The fact that we are still dependent on Fossil fuels should prove that we will never see an energy source that can support FTL travel.

Maybe, within the next few hundred years the world will see teleportation in goods. There are incredible things happening in teleportation. As far as FTL travel though, well the world would have to change drastically to see a technological advancement like that. If FTL travel were ever achieved it would not be known to the public. It would be a military asset. The world we live in...,could you imagine the potential destruction that would come with FTL travel? No, we would destroy ourselves. This doesn't matter though, because FTL travel is still theory and considering that as well as everything else going on in the world. FTL is nothing more than a pipe dream.

thats not what I read but sounds feasible your floating through on the hill right?

We will probably see these between continents in our life time.

I can't see ftl happening in the next 100 years although we will probably have sent probes that are capable of reaching a good percentage of light speed to our nearest stars.

Well, basically, just as you'd roll toward a (positive) mass because of its gravity well, you'd roll away from a negative mass because of its "antigravity" hill.

What I find interesting, now that I think about it, is that when the "antigravity" effect of dark energy is discussed, no one talks about spacetime curvature but rather Planck-scale spacetime "frothing" possibly being responsible for the repulsion. I guess one is a relativity POV, the other is a quantum-mechanical POV, and for now the latter is preferred because it jives better with the search for a quantum-gravity understanding, ie, the joining of the two major, but apparently incompatible theories: relativity and quantum mechanics.

Exactly.

Well the President of United States is black...so why not? 😂

Half.

It has already happened.

I saw it last night.

We were round a mate of mines having a smoke.
The announcement that a joint was being passed.

And I swear my mate Dunc broke the light barrier.

(Jumping in there so quick to intercept the motherf**er.)

He jumped in and broke the set chain of smoke? That is a no-no. Puff Puff Give; no cuts.

He was fast enough to give off Cherenkov radiation. That deserves, I think, one complimentary toke.

The drive to smoke the weed so bad was probably a Smith-Purcell effect. 😆

ROFLMAO 😂

I also theorise that he must've ruptured space/time also, as the situation seems to repeat itself over and over when hes about.

To be fair it was offered to "he who gets their first" but before the the "Ffffff..?" bit of the word "Spliff...?" has left the smoker's lips, that bastard's hand in already on the J/on its way to the J.

He normally like an aged old man on his unfortunate last stages of Kidney disease.

Yet somehow when the smell of weed fills the air, he suddenly possesses the ability to move so fast that he achieves superpositioning.

I know it's not as "mobile" as a volcano, but why don't you guys vaporize?

lol @ superposition.

😛 It might be the THC glueing our component molecules together.
