Today I Learned

[collinsmark]

I have a few things I learned recently in Kerbal Space Program during a mission to send a bunch of probes to Jool (Jupiter analog in-game). This one is too long to post here, but I made a post on the KSP reddit page here:
For Joules and Joules... the ups and downs of my adventure to Jool

Title is a reference to Alan Shepard saying his golf ball went "miles and miles and miles" on the Moon, it obviously rhymes with Jool, and it's a reference to the fact that rockets require energy to function. Triple play!

Great story!

Today I learned that the maximum time you can possibly survive after crossing the event horizon of a non-rotating uncharged black hole is about $15M_{BH}/M_{Sun}$ microseconds. (https://arxiv.org/abs/0705.1029, equation 18).

That's an entire minute in ours! And on whose clock?

Today I learned that the maximum time you can possibly survive after crossing the event horizon of a non-rotating uncharged black hole is about $15M_{BH}/M_{Sun}$ milliseconds. (https://arxiv.org/abs/0705.1029, equation 18).

Today (well, not exactly) I learned another rule of survival, the realistic one: Only 3 necessary "addiction elements" for all humans, and in the proper order of survival "approximate golden rule" to be followed (most of the time): "~3+ min without oxygen, ~3+ days without water, 30+ days without food ..."

[Sorry guys! This does not mention coffee, alcohol, smoking or any other addiction for that matter ... . Time to give up ... ]

Today I learned some things are just creepy...

Hours in the largest black holes we know.
On your clock, of course.

By "ours", I take it you mean Sagittarius A*? Yes. Although that has spin, so this isn't strictly applicable.

And on whose clock?

That's your own time (your so-called proper time) as you fall in, timing from when you cross the event horizon. I'm not sure there's a non-ambiguous way to talk about this period on anyone else's clock, black holes being what they are.

As noted, it's a maximum limit, and neglects the fact that you'll be torn apart by tidal forces at some point before then, even with a supermassive black hole.

TIL that the President of Nigeria, Muhammadu Buhari, felt he had to deny that he was a human clone of himself.
There is a conspiracy theory that he had died last year and was replaced by a clone of himself (or another person from Sudan).

Now that is what I would call art!

When we get to a level of technology when we are able to upload consciousness, I would totally trust this artist with my 3d representation.

"~3+ min without oxygen, ~3+ days without water, 30+ days without food ..."

~3 hours without an internet connection.

Why don't they just shoot us instead? ...

Just to quash the scurrilous rumors that have been circulating in certain quarters, I too deny that I am a clone of myself...

Now that you mention it, me too!

I can neither confirm nor deny that I am a clone of myself.

Neither can I.

Is that a double profile? Get him! ...

 

[Mark44]

Is that a double profile?

No, single profile, with multiple personalities.

No, single profile, with multiple personalities.

Or confused clones [using the same account] ...

Today I learned there is an ICD-10 code (International Statistical Classification of Diseases) for burn due to water-skis on fire.

That's convenient! I was actually wondering and worrying about that, to a degree that it was affecting my performance! ...

for burn due to water-skis on fire.

Wood, or fiber glass?

The question is, what does Mark43 have to say about it?

Wood, or fiber glass?

And initial water temperature 20.435°C or 20.44°C ? These are the big issues that need to be categorized! How else one can sleep at night?

He's missing (broke loose)

Well, doesn't that have a code?
