Is Phoenix A* is the biggest black hole in the Universe?
At 100 billion solar masses, it would be 50% heavier than TON618 and have a Schwarzschild radius of 1974 AU... that's 16 solar systems wide.

The wingtip pods are "flutter stoppers" that prevent the wings ripping off (and damaging the wind tunnel) in extreme cases. https://t.co/XS7cBVowTM

How do you refuel a fusion tokamak?
Many options have been explored for shooting solid fuel pellets into a fusion plasma at velocities up to 2000 m/s. High velocity gas guns, railguns, and in this case, various designs of pneumatic tubes are tested:
