Hohmann transfers take a long time, a long time spent in space soaking up those lovely cosmic rays (and God help you if Sol barfs a big enough cloud of charged particles at you). They got a design for a radiation-proof crew module, or are they planning to send Kerbals instead of humans?

Google “gyrocopter”. They’re basically a helicopter with an unpowered rotor that, nevertheless, and contrary to my ideas of common sense, fly.

Gyrocopters can’t fly. All documentary evidence to the contrary is a conspiracy. I refuse to believe that you can fly if you run fast enough while holding a big enough pinwheel over your head, which is basically their principle of operation.

Progressives who are never pleased as a point of principle ought not to be surprised when the political establishment stops trying to please them.

Oooh, really? Source? That would be great if true. Hiring smart people can’t do you any good if you’re too dumb to listen to them.

Yeah, this is one of a half-dozen or so Really Good Ideas for space travel that would be really nifty if we ever got around to inventing all of the technology required to make them happen. Space nerds are the universe’s biggest optimists and tend to forget that “physically possible” doesn’t always mean “practically…

No, dude, they’re just spitballing. None of this technology actually exists, and Billionaire Bro can’t afford to create it. This is about as meaningful as a five-year-old announcing that he’s going to the Moon, in the back yard, and about as likely to actually happen.

I’m pretty sure the unworkable elements of this plan start long before we need to worry about transmitting data back from Alpha Centauri — starting with the fact that it would take rather more than Billionaire Bro’s entire fortune worth of space infrastructure, infrastructure with a 0 ROI that he’s going to have a…

Riiiiiiiiiiight.

And I want a pony, but that isn’t going to happen either. WTF is this shit? “Oh I’d like to go to Alpha Centauri!” That’s nice Steve, now go play.

OJ saturation? You ain’t seen nothing, kid.

Go watch The Expanse; it will make everything better again (as long as you stick to physics and not biology).

Yeah. He’s pissed every other cohort off. White males are all that’s left, and 30% of us are liberals who would rather eat our own feet than vote for Trump. 70% of white males and 0% of any other group == loss.

I see. Have you considered marketing it to evil geniuses? I would think that would be a strong market for underwater lairs, er, apartments, and privately-owned submarines both. Perhaps offer a deal with some shark-mountable lasers?

Curious, were you doing this for shits and giggles or was a city paying you to do this? Can you say which/who?

Jeez, do I have to tell you guys everything? The interior of Jupiter is a diamond the size of the Earth. (Go read some Arthur C. Clarke. What are you even doing here?)

The weapon that was meant for Earth would have made a much bigger, brighter bang. It would also have hit us. The first thing we’d know about it would be, “Boy howdy, what just happened and why do we all appear to be queued up in front of these large, pearly gates?”

Uh... I don’t think very much of Jupiter’s atmosphere is actually transparent to the visible spectrum. So you would be looking at a lot of pictures of darkness.

Oh, you young people have no clue.

Somehow you failed to mention the most important factor driving my own purchase decision:
