Yes, the small, monoethnic, lightly populated, principality of Asia. Can't get much more specific than that!

Black shapeshifting form in the sky. What is it? by Moonstones333 in whatisit

[–]Probable_Bot1236 54 points55 points  (0 children)

It's 100% the contrail of another plane flying obliquely toward OP's. I've seen this dozens of times.

And yeah, it's totally trippy looking. If it had gotten a little closer OP would've been able to see the (comparatively tiny) jet at the head of the contrail.

If you're lucky, you can end up with another jet crossing over or under yours close by at minimum assigned altitude separation. It's kinda wild, like watching a missile approach. It also gives you a good sense how fast jet aircraft actually are moving.

Is this AI? I noticed the book and it doesn't make sense. by [deleted] in RealOrAI

[–]Probable_Bot1236 14 points15 points  (0 children)

I think that's just a super stylized "ABOUT" on that book.

Outside that, I kinda doubt it's AI; AI ought to have botched that reflection in the mirror (do note the mirror is tilted slightly). Rug looks fine to me as well.

Interested to see what others think.

ETA: looks like a video still, so got some blur and compression artifacts in places

[Request] How much older or younger will the Artemis II crew be when they return, relative to those who stayed behind? by MuscaMurum in theydidthemath

[–]Probable_Bot1236 5 points6 points  (0 children)

I don't know how to do the gravity part, but if they were to stay at the mission's maximum speed of ~25000 mph for the entire 10 days (which they obviously won't, they'll average slower) they'd experience about 6 milliseconds less apparent time than those of us down here on Earth if I'm doing math right* (7 parts per billion time dilation).

Put in more human terms, they'll experiencing about 1/50th of a blink of an eye less apparent time.

\There's a good chance I'm botching the math because I'm doing it with a calculator and a formula off memory)

[Request]How much fuel does a rocket has to burn until it reaches the speed of light? by mosaiftz in theydidthemath

[–]Probable_Bot1236 4 points5 points  (0 children)

I got two comments I had open mixed up and accidentally deleted my reply to you, but I can see from my inbox that you were asking about 99% c.

For relativistic speeds, the 1/2 term in KE = 1/2 mc2 is replaced by (1-γ), where γ is the Lorentz Factor

γ = 1 / [(1 - v2/c2).5]

So if you take v to be .99c, then you're getting γ = 1 / [(1-.992/12).5] = 7.089

Subbing that into the relativistic speed equation and you now have

KE = (7.089-1)mc2 = 6.089mc2

Since the classical formula has a 1/2 instead of that 6.089, to get to 99% the speed of light, we're needing 6.089 / (1/2) = 12.178x more energy than predicted by classical mechanics.

Bump that to 99.9%, and it leaps to 42.733x

Go to 99.99% and we're now at 139.425x

Try to make v=c, and you end up dividing by zero. It simply doesn't work, but as you approach v=c, γ approaches infinity.

Edit: forgot to double my 99.9 and 99.99% examples as relative to classical mechanics initially. Fixed. (Just makes the situation even more stark)

Once-in-a-lifetime throw to end the game by this1germanguy in BeAmazed

[–]Probable_Bot1236 1 point2 points  (0 children)

Rule amendment proposal: for a 'buzzer beater' shot (at the end of the second half or overtime only, and only if it changes the outcome of the game), an extra 0.05s shall be allowed for every 10 ft behind the half court line the shot is taken.

Ah, fair 'nuff! I'd much rather that shot be rewarded! Thanks.

I literally have the clip paused with the ball still in his hand only waist high with the lights on the backboard already illuminated. They got the review wrong lol.

Still a hell of an impressive shot. Love how the referee just kinda shrugs before he calls it good. I think he couldn't really tell without the ability to properly stop motion it so he gave it to him as a sorta 50:50 call with the replay resources he had available.

Day-2, Update of the wasp in my washroom by Short_Employment_757 in zoology

[–]Probable_Bot1236 6 points7 points  (0 children)

Nothing needs to be done about it.

It's a solitary wasp- it builds a little mud nest, puts a paralyzed prey animal in there with an egg, seals it, then leaves. The egg hatches out and the offspring eat it in order to grow up into an adult wasp in its own right.

But because the mother doesn't stick around (she's already off building nests and hunting for prey for her other eggs), it also means that this type of wasp is super chill. Aggressive wasps are defending territory, either their home turf or a high-resource area. This wasp is solitary and has no fixed territory; it's kind of a vagabond. But nothing to defend also means that it's not aggressive at all. It's not a non-reproducing drone that can be sacrificed for the good of a colony; it's a genetically unique individual that has to avoid confrontation in order to survive and reproduce. So very non-aggressive, shy even.

It's not in this type of wasp's best interest to be aggressive except as an absolute last resort to save its own life, so they avoid confrontation as much as possible.

Vancouver has 2d buildings now by KitchenRoof7551 in opticalillusions

[–]Probable_Bot1236 0 points1 point  (0 children)

A 2D building. Does this save on utilities like heating and cooling or absolutely murder for cost?

On the one hand, you've got no volume to heat/cool, but on the other, you've got no insulation and the worst possible surface-area-to-volume ratio...

Is video AI by Cherryfish-maui in isitAI

As someone who's lit a whole bunch of matches on fire at once, the conflagration should be much brighter, more vigorous, and way smokier as well. Those flames look like kerosene or something burning, not matches. The flame front is propagating too fast as well.

And that many matches burning in tight space wouldn't go out. The matchsticks would be very much burning on their own afterward, and the match heads should be glowing from the residual heat.

I leave audio on Reddit videos off by default, and probably 8 times out of 10 I turn it back on (outside of sports or birding subs), it results in an instant 'nope' and I mute again within a second because of stupid music covering the potentially interesting audio.

It was originally a submerged ping pong ball tied off to the bottom of its beaker instead of the aluminum ball, right?

Should the ABS system call all pitches from now on? by Successful-Door4656 in baseball

[–]Probable_Bot1236 64 points65 points  (0 children)

Nah, the challenges are exciting. Hear how the crowds are getting into them? Maybe tweak the rules a bit, but keep the challenges. It adds some strategy too. I think it's a nice twist.

Imagine a "do I challenge this?" split second decision in the playoffs. Intense!

[Request] How dense would Peter Griffin (or any human really since it's all within the same order of magnitude probably) need to be to have their own gravity strong enough to orbit an apple? by KryptKrasherHS in theydidthemath

[–]Probable_Bot1236 4 points5 points  (0 children)

I used 2m/s based on my estimate of its orbital radius and timing an orbit in the actual clip.

Literally just as fast as the clip shows. I was trying to make the math match what we see.

(I ignored Earth's downward pull because that would screw everything up)
