Seems to me if some civilization out there figured out how to go faster than light we would have already been visited and I see no reputable evidence for that. That implies even if we see signs of advanced civilizations, that is ALL we will see because it may be a real speed limit.
All the work with positive and negative mass propulsion systems so far are just wishful thinking. If they make a craft taking ten minutes to go to Pluto, that will be one thing, but till then, it's all conjecture.
@sonhouse saidBig surprise. Did you expect see anything? Stars are too far apart.
@Metal-Brain
We have yet to see even a single unblurred image of an alleged alien craft yet.
@sonhouse saidIf aliens visit distant places, I doubt they do it in physical craft propelled through 3-dimensional interstellar space. There would have to be some other way which entirely circumvents the 'speed limit' and the vast distances, of which our present understanding of physics has not the slightest idea.

Personally, I rather like Frank Herbert's idea of 'folding space' (from the sci-fi novel Dune).
@moonbus
We do have ideas to exceed the speed of light with real warp drives but requires something called negative energy and postive energy one set in front and the other set in back of the craft and that allegedly can allow faster than light travel but this negative energy bit sounds like la la land so far.
@Metal-Brain
Yep you really are one of the most intelligent commies on the planet.
Did I say we have no unblurred images of alien spacecraft around their home star?
I am talking about the 'sightings' of ones that could be nice crisp pictures if our good cameras like the Canon's or Nikons and the like with good telephoto lenses and such that can take a picture of an eagle 10 miles away, no images of that kind of quality has ever been taken, instead just blurry images of crap that could be a pie plate thrown in the air and photographed with crappy cameras that make blurry images on purpose so the image means nothing but will be taken as 100% real by the UFO nuts abounding in the world, which is one more way of showing how the vaunted intelligence of humans is not as great as we like to pretend.
All we have to do to see that is look at the millions of Trump supporters who cannot see the deterioration of Trump going on right in front of their eyes and I bet you never saw the "Shark' speech did you? A bizarre POS incoherent blubbering crap that even the audience was left going "WHAT THE HELL?"

Dunning–Kruger effect
Wikipedia
https://en.wikipedia.org › wiki › Dunning–Kruger_effect
The Dunning–Kruger effect is a cognitive bias in which people with limited competence in a particular domain overestimate their abilities.
Trump is a poster boy for this effect.
"I am a stable genius' and OF COURSE his stupid base believes everything he says.
@sonhouse
'Because I once had a vague connection with someone from MIT, I'm a really smart guy and I know all about sharks and electricity.'
"Inject bleach."
"Nuke a hurricane."
The man's a nitwit with a ludicrously inflated opinion of himself. His only 'talent', if one could call it that, is convincing other people he knows what he's talking about.
😆
@moonbus saidThat is impossible. c is the speed limit.

It would take so long for them to get here they would send robots with AI instead of themselves. The notion of alien bodies being found at Roswell or anywhere else is ridiculously absurd. They would not dare risk contaminating our biosphere with alien microorganisms unless they intend to sabotage life on this planet anyway like the movie Independence Day and replace us as the dominant species.
@Metal-Brain
c is not the limit for spacetime. That is the point, there is at least theoretical work being done on space warp drives which puts a spacecraft in a protected bubble with spacetime bending one way in back and the other way in front so you theoretically can effectively go faster than the speed of light.
Of course a rocket cannot get to the speed of light, probably might get halfway there with antimatter rockets but that seems to be about it.
Still that makes a journey to Alpha Centauri happen in about 9 years one way.
Which could be done. The science is there for that at least.
And don't go into a tirade that anti matter rockets are impossible, I don't want to hear it.
@sonhouse saidSci-fi nonsense.

@Metal-Brain
Funny how NASA thinks there might be enough in those theories to fund research about the ideas.
But keep on with the negative comments, take them to your real boss Putin, we may win out with the first faster than light drive before Russia can screw it up.
@sonhouse saidIdeas?

Any nonsense can be an idea. Extracting energy from the vacuum of space is an idea. Doesn't mean it will necessarily work. People have all sorts of crazy ideas.
