ET's/Aliens yes or no?

This is what I doubt. Sure there may be more advanced species than us, but to get to the point to be able to travel between life supporting stars is a huge undertaking. It could possibly take generations upon generations upon generations...etc to do it. No contact with your home world, possibly no contact with any other being. You could just be adrift and have a new civilization in space and go absolutely nuts til the dumbfuck on the ship blows everyone up.

you are thinking along the lines of human (or close) technology. If there is a civilization that has conquered space travel, they are most definitely not using thrusters to rocket from star system to star system. We already recognize the plausibility of using worm holes / folding space, we just lack the technology and energy resources needed to harness them. That is just the theories that we have put together here in the last 20-30 years. such a civilization is most likely instantaneously moving about the cosmos.

I agree that the likelyhood of a long lasting spacefaring culture being limited to reaction thrusters being low. Something you've missed is they would almost certaintly have had to develop some sort of inertial compensator. Nobody likes going splat when the engines come on

Yea but alien is alien, suppose they live 1,000 years or are immortal? Maybe they are super tough and can handle any amount of g force thrown at them...

Or they resemble squids and live in a liquid environment that would have a far higher g tolerance

Maybe they are cookie cutter sharks?

If they have some kind of "space folding" technology, no physical acceleration would be required.

Conjecture. No ones ever done it

his point is that it is a doorway, so one would require only lateral movement to "walk through the doorway", on the other side of which would be another point in space-time.
