I just watched like an hour's worth of YouTube vids on what dark matter is and I'm not any closer to understanding what dark matter is than an hour ago...
@Starprophet1@AmonMaritza@JoePrich >Of course, "dark matter" could just be .... Or, as has been theorized, just a rounding error in the math of assumptions used by astronomers. Leave it to modern scientists to look at an issue with their equations and assume that the universe is wrong, not them.
If the QI drive actually works (I'm skeptical), it would be pushing against the mass of the Universe or the local area in the galaxy/solar system, without touching said mass. Vastly more efficient (understated) than using on board propellant to push against.
Of course, "dark matter" could just be rogue planets, black dwarfs, cold neutron stars, near absolute zero, or just small black holes with no accretion.
There was a QI drive that was to be tested by the Barry-1 satellite (launched on a routine cheap rideshare by Elon's partially reusable Falcon 9 launch vehicle). But the satellite suffered a power failure before the propellantless drive can be started.
With routine Falcon 9 flights every 3-4 days, there will be another chance to test that theory with a reactionless drive in orbit. With daily fully reusable Starship flights, there will be orders of magnitude more chances to test.
It will be interesting if such a drive can raise a small satellite's orbit.
Let's say, if it works, combined with cheap daily fully reusable launches to low earth orbit, it's going to have a significant impact on spaceflight.
