Elon Musk buying Twitter

[Aloha_Shooter]

If I had that much money, I'd be building nuclear powered space craft that can do C+. It is called break through propulsion physics. If you can build starships, you could own this planet.

I was referring to photo fission propulsion that is capable of faster than light travel. Not sure if this covered by laws governing nuclear technology. Building this technology would probably be insanely expensive, but not impossible. Admittedly it is an exotic materials problem and uncharted territory.

More than insanely expensive, what you're talking about requires new physics. Not just new engineering, new physics. Even getting close to c requires changing paradigms (like Robert Forward's laser pulsed lightsails) to get around the mass of storing on-board propellant. The nice thing about Robert Forward's stories was that he explained the physics behind them in the appendices to the stories. As much as I would love it, I haven't seen any credible physics for FTL travel.

Musk is already putting significant sums towards pushing space technology. He can do that and still bait the totalitarian demagogues at Twitter. In fact, it looks like he's baiting them AND going to make a huge profit at the same time. I've heard someone else has put forth an offer to buy Twitter and if it competes with his, he'll be able to nearly double his investment and then watch them go down the tubes. Musk right now seems to be the closest contemporary analog to Heinlein's fictitious characters of D.D. Harriman and Shipstone and our best bet for really pushing outside Earth's gravity well.
