my money is on markov chains, no human is _that_ bad at grammar

#4so, I didn't quite get the connection between element 115 and superferrofluids/the warpdrive theory...is element 115 a superferrofluid? or did that first part of the article have nothing to do with the rest of it?

#5I'm sorry, that was a super disappointing reveal.
"However, we would expect the centrifuge to gain mass (and hence generate an increasing gravitational field) as fluid spins up to relativistic speeds. Hello warp drive! Oh, and you’re welcome."
Congrats, E=mc², you've collected a large amount of energy in a small area and created a gravitational field. You've now reached the space travel and anti-gravity technology of a small rock.

#6a superfluid flows with zero viscosity, that means if we were to put it into some kind of centrifuge and spin it, it would not slow down due to friction. If it never slows down due to friction, in theory, that implies we should be able to accelerate a superfluid to the speed of light.
ah ah ah ah nope.

#7Why do you need a superfluid? It sounds like all you need is disc in a vacuum that you suspend/rotate like the armature of a motor.
Until, of course, it gets nowhere near the speed of light because the limiting factor to spinning something fast isn't friction, it's the required centripetal force to keep it in one piece.
And assuming you could solve that by making the spinning thing out of unobtanium, you're still not doing anything to break conservation of momentum.

The latter. He was just citing another conspiracy theory of how to create a gravity engine / warp drive that had become more relevant with the actual discovery of E115.

In think the point was sightly different - roughly that as a particle approaches the speed of light, its 'inertial mass' approaches infinity (as it requires more energy to speed it up). Unfortunately this 'inertial mass' is unrelated to gravity.

But is that not why he is using a fluid? A fluid does not have intermolecular bonds that need to overcome the centripetal force, so it shouldn't be a problem?
