You and I both my friend. You and I both.

I agree with you, we don't know it all. But based of what we do know is why I am been so stubborn.
This is what I am talking about when I refer to energy, time gravity and spacetime:
Stars are supported against gravity by the thermonuclear fusion in their cores. Fusing lighter atoms into heavier ones releases energy, but those heavier elements require higher temperatures to fuse again. If the star isn't massive enough to ignite the next element, or if it reaches iron, fusion stops. Then gravity gets to continue the job it started billions of years before, crushing atoms.
Small stars end up as white dwarfs are with are dense. But larger stars become neutron stars (try to remember this name).
Atoms in neutron stars are stomped into each other, negative electrons physically crushed into the positive protons to create an endless mass of neutral neutrons.
Ok, the resulting neutronium (from neutron stars) is 40 trillion times denser than lead. If you stood with a spoonful of neutronium, it would fall through the spoon, punch through the Earth until it shot through the core and out the other side. Then it would turn around and do it again, and again, and again and again, until it got stopped by friction. It's as dense as anything can get without giving up on matter entirely and becoming a black hole.
That been said, this is what's needed to create a worm hole, as per NASA, based on the sciences that do exist today:
"First, collect a whole bunch of super-dense matter, such as matter from a neutron star. How much?- well enough to construct a ring the size of the Earth’s orbit around the Sun. Then build another ring where you want the other end of your wormhole. Next, just charge ‘em up to some incredible voltage, and spin them up to near the speed of light -- both of them."-JPL NASA
I am not saying that we are the only ones out there. I am saying that the universe is huge, our galaxy alone is 100,000 light-years in diameter and contains approximately 250 billion stars. It may contain at least as many planets as well. It could be teaming with life as we speak. And could have civilizations far advance that ours.
The problem is that our closet star system is more than 4 light years away. Time, energy, gravity, spacetime, should be a problem for them to.
For example, the Voyager spacecraft left the solar system at 37,000 miles per hour. At that speed, it would take Voyager 80,000 years to reach Proxima Centauri.
80,000 years is a LOT of time. And that spacecraft is the fastest object mankind ever made. (the speed is relative to us).
So again, I don't know. Maybe I just wrote a lot of words to say just this. I do think their is life out there. Them coming here or we going there is very unprovable.
Take care,
