Baseball doesn't take muscle power. Except maybe the pitcher.

Seems the gamma rays generate a current in the atmosphere [which
wouldn't happen if there was no atmosphere], and the magnetic field
channels this to the ground [in certain parts of the globe which happen
to include the USA].

More reliable than (say) three spinning backups?
Plus, you'll *always* be able to find a machine capable of reading your HD
before it wears out. What would you do with a stack of 9-track tape backups
today?

Right. You make two, actually.

A hard drive the size of your current hard drives is too small?

The Steam installer allows you to choose where to install it. Since Steam
always installs games in subdirectories of the main Steam directory, this
is the only official way to get the games off the system partition.

We used to use DDS-3, DDS-4 and DAT-72. (Don't you love how all tapes
have storage capacities "assuming 2:1 compression"? I have never seen
any backup job achieve anything approaching 2:1 compression.) Never had
any significant problem. After about 4 years the tape would wear out,
but that's hardly a big deal assuming you notice this and replace the tape.
Never had any issues of any kind with restoring data from tape.
I *have*, however, had endless issues with BackupExec not actually
****ing working properly! >_<

I think we had 1 tape drive wear out. (We had about 6 of them.) And it
was the oldest, crappiest one of the lot.
Seriously, I did tape backups every single weekday for 6 years and had
almost no issues related to the tapes or tape drives. That's not what
I'd consider "unreliable".
> I had much better luck with DLT drives.
I have no idea what DLT is.

Really? I would have thought running around requires *lots* of muscle
power. (That's why I can't do it, for example...)

Not if Einstein is right. And he seems to have been right about a pretty
lot of things he didn't even dream of.
Note that rotation is not just movement - it is accelerated movement
(with the direction of acceleration changing over time), which is why
you can tell that you're not just moving linearly.

... at the incredibly deafening level of -1000 dB I presume. With your
own ship's engines roaring along at some 1000 dB to make up for it.
Yeah, technically you're right :-)

... and it tears holes into the subspace, though they kept that secret
until some seasons into TNG. What was the speed limit after that? Warp
5? Or was it Warp 3?
But then again, Warp isn't a multiple of c anyway, it's a level of
distortion of spacetime (hey, it messes seriously with /normal space/,
so how could they possibly expect to not affect /subspace/?) while you'd
still travel sub-lightspeed, possess a finite real mass, and just need
to travel a significantly shorter distance.

Not really, provided you don't forget to properly "pop" your ears during
decompression.
It's your eyes that might not like it, so you better close them...

The vibration of the other ship's hull would probably modulate the rate
of gaseous emission and/or the speed of the molecules. So the sound
might even undergo less distance-based dampening than in a denser medium.
The impedance-based dampening, however, would be pretty strong I bet.

The good news is, others will have taken their place by "now" (whenever
that may exactly be :-))

Yeah, but the majority of baseball players usually just sits or stands
around during the whole game (at least statistically)... and besides,
they use natural talent, trained skill and illegal substances(*), not
brute muscle power :-P
(* no, not drugs, but stuff to manipulate the ball :-))
