--I got invited to write for a blog on interstellar probes and stuff though.

--Anyway as I said I'm just a layman when it comes to propulsion...and pretty much everything now
30 Jun 02:07
--Just saying oh look, x energy there, therefore let's have it because maths and stuff lol
30 Jun 02:06
--People have worked out the maths... and stuff, and capturing even a little bit of the sun's power could drive hundreds of ships to the stars.

--It also takes a huge amount of energy to move things at near relatavistic speeds
30 Jun 02:05
--Oh, definitely. That is the fly in the ointment. Also, you need insane amounts of power for good thrust.

--Easier said than done to efficiently convert the energy from photons into propulsion I think, but I know nothing about the theory

--A chemical rocket would require a literally astronomical amount of fuel to reach a high enough speed for interstellar travel.

--His concept was literally a light-rocket, which converted matter to energy and exhausted said energy as massless radiation. It works better for reaching high speeds because... maths, and stuff. LOL

--Robert Forward came up with the staged sail, but people had already talked about them earlier.

--People don't talk much about photon rockets these days, they probably aren't practical. But the implications of these kinds of voyages are mind-blowing.
