Would it have negative gravity? As in, the law of universal attraction would actually repel other matter?
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?

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.

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.
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.
