I said OUR...as in OUR collective scientific knowledge.
Just becuase we have not discovered a technology does not not mean that technology doesnt exist.
Before the light bulb there were no light bulbs.
E doesnt = MC squared...there is something missing in the equation...becuase we cannot reverse it.
We can quite easily turn matter into energy.
But we cannot as of yet reverse the equation and create matter out of energy.
The abilty to reverse this equation is the the key to + light travel.
And I’m quite sure the answer involves the secrets of gravity and time space displacement.
ok, my mistake. i read your comment with “your” instead of “our”, still my points stand.
however, don’t confuse wishful thinking and science fiction with real science. there are certain truths about the universe that are inviolate. things such as the forward movement of time and the speed of limit being an upper bound. it’s fun to have thought experiments about what “could” be if such things were not universally true, but lots of experimental evidence exists to confirm that they are.
i’d love to be able to travel back in time, or to visit another galaxy. but those feats are beyond the realms of possibility according to everything we understand about the universe. sure, we can say that we should never rule out anything as being impossible as a matter of principle since we are not God and do not understand the true nature of the universe (since physics is ultimately just a way for us to model and predict future behaviors), we also shouldn’t fall into the trap of thinking that all things are possible. clearly, this is not true. experimental evidence shows that our current models for most of the big things work very well and only really require occasional minor tweaking for odd corner cases as they are discovered (such as the behavior of energy/matter at the event horizon of a black hole).
things like interdimensional portals between universes or distant points in the same universe are just mathematical conjectures. fun to think about, but purely in the realm of speculation at this point.
back to the original point about aliens. if there is anything else out there, the odds are astronomically against us ever knowing about them or vice-versa. simply because the distances involved are vast. distances of a billion light years are not really that extreme in an observable universe whose diameter approaches 90 billion light years. when you compare the volume of the universe within 1 billion light years of earth with the total volume of the observable universe, it’s a really small percentage. and that’s not even taking into account the unobservable universe with which we can never see nor interact with.
it’s these sorts of distances never taken into account in sci movies or “had waved” away with things such as wormholes and warp drives, which nevertheless make it highly unlikely that we’ll ever encounter any other life in the universe, even if it’s out there. then add to it the problem of time, and it gets even more unlikely. let’s say that there was a civilization a mere 500 light years from earth that was capable of interplanetary travel. if they existed concurrently with us, then maybe... just maybe... we’d detect their transmissions and vice versa. but let’s say they came along 500 million years before us, or 500 million years after us, or 5000 years before us, etc. we would never, ever know because even though we’re essentially next door neighbors at a mere 500 light years apart, one of us came and went before the other was around to see our EM fingerprints.
