A warp drive requires bending space. Space can bend, we know this because of gravity, everybody knows what that is, we all feel it every day, the whole thing, whatever. Mass bends space. How do we bend space without mass? Does anybody have any ideas?

A warp drive is mathematically possible under general relativity, but it remains unfeasible to build due to extreme energy and engineering limitations.
Energy Requirements: Early calculations showed a warp drive would need an amount of negative energy equal to the mass of Jupiter or the entire universe. Refined shapes (like toroidal rings) have lowered theoretical requirements closer to the mass of a spacecraft, but generating and storing this energy remains out of reach

This is why we should just send AI with the human cloning know-how into space already. No waiting around for magic speed, just make AI the gardener of humans, seeding planets with the first generation of them
It all comes down to artificial wombs. Even then AI would have to be a lot better and that's putting it lightly. But it's still a better chance than waiting around for teleportation or something, or actually having people live in space ships for years and years

Clearly their must be massive number of planets with life on them. Some of human form and others with god only knows, what life forms exist.
You would think so, I mean you do hear of earth like planets, but I don't really pay attention to it. Regardless, if perfect planets tend to also have alien microbes, it's yet another case for artificial wombs, because resistance to those microbes would have to be "installed"

I think there are planets that have complex life. I don’t know how common it is, we just know the odds aren’t zero because we’re here, and the universe is infinite. There are other planets out there that have life as complex as we are, and given the universe is 13.8 billion years old (assuming there was nothing before the big bang which I don’t really know if I buy that), the Earth is only 4.5 billion years old. There were sun like stars that are billions of years older than the sun that are dying or have already died. I don’t see any reason why it couldn’t be the case that there could be intelligent civilizations that are already billions of years older that are so far beyond us in terms of intelligence that we wouldn’t really be able to understand them. They’re probably so far away they can’t reach us due to the laws of physics preventing faster than light travel.

The estimates for the number of stars in the Milky Way put it on the order of magnitude of hundreds of billions of stars. A million is a tenth of a percent of a billion. Empires could exist that we don’t even know about.

Jesus. Science fiction generally uses a bit of magic but that’s insane. I always wondered how you could reduce people to particles and reconstitute them.

Do you want to meet aliens who get here first? We all get to be the Aztecs.

The reason why it requires so much energy is because we know that mass bends space but we don’t know why and we know mass is equivalent to energy, so the calculation is just assuming that the only way to bend space is having enough mass and there’s no shortcut. I think it requires an understanding of quantum gravity though to be able to determine why mass bends space and if there’s any way to bed space more efficiently.

It’s sort of like if you knew about magnetite, and you were calculating how much magnetite you needed to lift a car and you just assumed that the mass of magnetite you needed was fundamentally proportional to how much magnetic field you got and you had no idea there was a more effluent way to make a magnet. I’m not saying there is a more efficient way, I’m just saying that’s why the numbers are so high.

Makes me wonder if that’s how humanity started. What if our progenitors were ai and made us? Was there an episode of that on ancient aliens?

I don’t know actually. It depends on how much more advanced they are than us. If they were less than 10,000 years more advanced to us and had a similar level of intelligence to us, but they could reach us somehow, if they were from another star system, they’re not going to be threatened by us. We have no technological means of causing harm to them in any way whatsoever. We can’t attack another planet in another solar system with aircraft carriers or whatever, it just doesn’t matter. So it’s completely up to them if they care or not or like us or don’t like us how that goes. If they’re millions of years more advanced than us, they might see us the way we see animals, not fully sentient in the way that they are.

And there are other animals on Earth, like birds for example have a much higher neural density than mammals, but they’re tiny so it doesn’t really challenge us. So it is possible a brain that’s the same size or smaller than ours could be more intelligent than ours. The human brain is actually mostly fat cells by volume.
