I think Boku no Hero Academia now gets my vote for best anime series soundtrack.  And it's utilized so perfectly, too.

Appropriate. :D  I had mixed feelings for that movie, but the music and visuals were sure awesome.

Science and Astronomy Questions

22078 Will the Venus encounters have enough gravitational energy to slow it down enough to eventually "touch " the sun's corona? The Sun's corona doesn't really have a hard limit to it, but rather smoothly transitions into the solar wind, filling the whole solar system.  In a sense, auror...

Astrophotography

22060 I would like to have all possible critics to keep improving. However, I have a big question: What's that blue "cloud" in the left botton? There is a star cluster there, but it shouldn't be that blue. 22069 Blue clouds in astrophotgraphy are typically over-exposed or color-enhanced r...

Ah, Aphex Twin.  I can't decide if I like this track or not, but the video is sure trippy.



Added:  Actually, the more I watch it, the more impressive it gets.  Especially the final third.  I can't even begin to imagine the work involved in creating this.

22008 This raises an interesting point as to the affects of time dilation, as I remember reading about that famous experiment involving the ISS astronaut Scott Kelly staying aboard the ISS for 520 days — all of which he spent zooming around Earth at 17,500 mph (28,160 km/h). When he came back do to...

Science and Astronomy Questions

In some case it is close, but not exactly.  The definition of the Roche limit is rather fuzzy and depends on some assumptions about the structure and rotation of the moon.   If we assume the moon is very rigid and it is the same density as the planet then the Roch limit is about 1.26 times the plane...

Science and Astronomy Questions

While playing around with time dilation formulas, I just came across something interesting. If a ship is in a circular orbit at exactly 1.5 times the planet's radius (this is 3185km altitude for Earth), then its clocks will tick at exactly the same rate as clocks on the planet surface.  For a closer...

That's an interesting way to put it.  I don't normally think of it that way, but I suppose the logic could be expressed in either direction, like saying that gravity is things trying to go to where time passes the most slowly. :)

21980 There's another thing to consider: latitude.  It's perhaps the most important variable? Very surprisingly, no!  A point on the equator rotates about the center faster, which would make us think clocks tick slower there. But the equator also bulges outward due to Earth's spin, bringing it fart...

21964 I calculated that I've spent just over a week airborne over the past 12 months covering a distance of about half a light second.  Does this also mean that I've travelled half a second further into the future than if I'd remained at home, or is the maths more complicated? Yes, it is more compl...

A nice demonstration and explanation of the Belousov–Zhabotinsky reaction.  This reaction creates repeating, propagating waves of color, and also shows chaotic behavior.  As the title says, this is easily one of the weirdest reactions I have ever seen.

21934 It was a mentally brutalizing encounter and I only just escaped. I tried not to get involved in their "conversation", but their.... lack of good research was most aggravating. It's not worth getting worked up over.  Very few "flat earthers" are serious anyway -- most are j...

The shape of the Earth's shadow in one lunar eclipse isn't proof that Earth is a sphere (a flat disk or cylinder would also work), but that the shadow is circular for all lunar eclipses, where the Moon is in different parts of the sky, is, because that then shows that the Earth projects a circular s...

21916 That's were Copernicanism won. Because copernicanism relied on a disprovable idea (and also because of Occam's razor; each new epicycle is a new assumption of how things are in reality while the Heliocentric model relies just in one assumption one might say). We could also say the Heliocentri...
