...30 orders of magnitude more than a nuclear power plant.
We just a need a moore's law of nuclear power and we'll be able to have lunch at alpha centauri and be back in home in time for dinner!

Depends on the time of day.
Actually it doesn't. The difference between perihelion and aphelion is around 6 million km, and it takes approximately 6 months to cover. That means Earth is moving away or towards the sun at 1 million km per month. That's 33,000 km per day. So 1300 km/h or so? Basically unless you're really fast, climbing the stairs is overwhelmed by other effects. Haven't taken the Earth's rotation into account but it should be les…
July 4 is aphelion day this year, so celebrate by doing an entirely useless physics problem.
What is impossible in 2D (e.g. escaping from inside a circle) is possible and trivial in 3D. Is moving faster than speed of light a limitation that can be overcome in a higher dimension? Does it really require a lot of energy or is that only so under certain circumstances? There is a lot we still don't know
The 3d equivalent of a circle is a sphere, which is also impossible to escape from in 3d.

Have we truly been ready for any of humanity's technological developments? They tend to be very messy, and lead to all sorts of consequences few could predict.
We somehow managed to survive nuclear weapons (so far). But imagine things as simple as a pathogen or invasive species from space the kind of mess it will create when a year later covid is still not under control.
In fact it’s very unlikely. On Earth we have a planet full of the results of 4bn years of competitive evolution. Put that against one single species resulting from evolution. The chances are at least one species on Earth will eat its lunch. Furthermore Earth life is customs tuned to the Earth environment, but the space bug is most likely optimised for a different environment.
> After studying existing research on warp drives, Lentz realized there were specific forms of spacetime bubbles that scientists had overlooked. These bubbles took the shape of solitons, or compact waves that maintain their whip while moving at constant velocity. Anyone else remember TNG 's New Ground ? That was the episode where the Enterprise helps test a soliton wave-based warp mechanism. If I remember right, Geor…

There is no causality paradox with warp drives.
Nope. Literally any method of getting from A to B faster than light would, has a causality paradox. it does not matter if you cover the miles between FTL, or pop out of a hypothetical wormhole gate: If you end up outside of your own light cone, no matter how, there's a causality paradox.
Pretty much every explanation I've seen as to why this would ostensibly be so would - when applied consistently - consider the average thunderstorm to be full of causality violations because you can see the lightning before you can hear it.
It shouldn't matter how long it takes me to go from Point A to Point B. As long as I arrive at Point B after I departed from Point A, then causality should be preserved. Doesn't matter if n=1s or 100s or 10000s or 0.0000000000000000000000001s. As long as n is positive, then where, pray tell, was causality violated?
And it shouldn't matter if someone else sees me arrive before one sees me depart, for the same reason why it shouldn't matter if the light from a flash of lightning arrives before the sound does. That is: just because you perceive something out-of-order does not mean it was actually out-of-order.

Why, when you could just have your dinner sent through the Great Burritos Wormhole?

I just watched this a few days ago. The soliton wave was sort of a magic carpet. They, of course, decided to test it by aiming it at a colony...
Humanity has evolved so much by the 24th century that they have to make up contrived problems for the Enterprise to solve, otherwise the Enterprise crew might spend all their time on Risa (well, okay, maybe just Riker). It's not even like Q forced them to aim the wave at an inhabited planet, they just did that by themselves. Also, couldn't that have used this tech to send superweapons towards Borg space in the Delta…
And then Q, uninvolved but likely bored with whatever else he was doing, bullying some stardust or something, and omniscient enough to hear Picard shouting, would dutifully appear. He'd turn the whole impossible situation into an unfair but winnable game, gleefully taking credit for the whole thing, and having so much _fun_.
I bet Picard could've pulled that about a million times!
Since we have never been visited by aliens, or witnessed time travel, these things must not be possible. It they were, there would be proof and it would be documented. It's as simple as that.
This is a rather large assertion to make.
