“Does anyone believe that God can’t go anywhere he wants.”
It is sacrilege to attribute human attributes to God.
“Figuring out gravity, beyond Einsteinian 3D space/time, is the crux of the biscuit.”
In Einstein’s 4D space time there is no gravity.
I have been seeing his videos all over my Youtube feed. I wonder why are they pushing these videos now?
Not only that, but thinks from outside the solar system occasionally visit us. It would be good to learn how to deal with them.
No. All my life I have heard the assorted Carl Sagans assure the public that life is ubiquitous throughout the cosmos in part due to an assumption that it arises so easily.
Nice Animaniacs reference.
“No. All my life I have heard the assorted Carl Sagans assure the public that life is ubiquitous throughout the cosmos in part due to an assumption that it arises so easily.”
Evolution does not speak to the origin of life.
There is one more very important problem and that is the technological advancements that will happen during that 2,900 years. Lets say this society 2,000 years later develops a ship that can go 10X faster. The 2nd ship will reach its destination some 700 years before the first ship does. This means all the people on the first ship wasted their lives for nothing.
“We have already detected particles that travel at faster than the speed of light.”
I gave that statement a big wrong because, based on the rest of your post, I assumed you were referring to the speed of light in a vacuum.
“It’s an invention to make the math work with no correlation to reality.”
As was Newton’s gravity.
I have a son who was a submarine officer. He would agree.
I assume your “thinks” is “things”?
There are plenty of other places people can travel to in the Solar System. Since robots don't need to breath they can do most of the work needed before people settle down. It will make Space a very profitable opportunity instead of the money pit it is now. Another good reason is the preservation of Civilization itself. With people spread out all over the Solar System it becomes very difficult for humanity to destroy itself.
It not be looping around the Moon just like the unmanned Artemis I didn't do.
Yes

Star Trek Voyager did it.
Pffft. But a small price to pay to be everywhere all the time.
“Even with a pessimistic view of the Drake equation... Us being alone is mathematically impossible.”
Except that mathematics works both ways. The hard fact is that we have no idea at all how likely it is that living systems could arise on a planet in a given star system - and that’s partly because we have virtually no idea how the molecules required for living systems (particularly proteins and nucleic acids) evolved from simple molecular precursors.
So even if the universe contained 10^80 (ten to the 80th power) stars, if the odds of life arising on a planet in any given star system were 10^(-81) (ten to the minus eighty-first power), then the math tells us it’s almost certainly us and just us. That latter number could be 10^(-70), it could be 10^(-90), it could be ten to the minus damn near anything - we have no earthly idea what it is.
So you could have a star the size and stability of our sun, located in the same Goldilock’s zone of its galaxy with a planet the same size as our earth in the same Goldilock’s zone of it’s solar system, with the same unusually-large moon producing significant tidal forces, with lot’s of water on that planet, etc, etc, — we still would have no idea how likely it would be that life would appear, because we have no idea of the mechanisms by which the exceedingly complex and exceedingly structurally-specific molecules required for living systems were generated.
