It is impossible for anything with mass to travel at light speed. Even if it were possible, entities traveling at light speed (1) do not experience time, at least not in the way that a sub-lightspeed entity does, and (2) are effectively unable to communicate with sub-lightspeed entities. In fact, the only thing they can “communicate” with is the thing they’re going to collide with due to relativistic beaming.

So given the above: if you imagine that you were traveling at light speed toward a black hole, you’d have to think of it as experiencing your whole existence simultaneously. Your creation, crossing the event horizon, being stretched by tidal forces, and collision/absorption into whatever exists inside the sphere… all happens at once.

That’s not entirely true for a sufficiently large black hole. It’s possible to cross the event horizon before tidal forces are strong enough to cause problems. You’ll definitely be ripped apart eventually, but you’d at least be able to see the inside before you become atomic spaghet.

Turns out the old gag “You can’t get there from here; You have to go somewhere else and start” is actually true for btrfs’s RAID support.

Bro The RAID Fuckin’ Sucks

ZFS for “RAID” is fine. Btrfs for a single disk (or on top of mdraid or hardware raid) is also fine.
