This is so ridiculously clear it somehow appears 3D.

u/brin_shut Dec 13 '19

yeah what is up with that? the background moves with my eyes

u/Morgnanana Dec 13 '19

It's caused by The Pulfrich effect.

Essentially, your brain is slightly faster at interpreting bright optical signals compared to dim ones, and as a result whenever you move either your eyes or the screen there is a split second delay in apparent movement of the bright moon and much dimmer background.

So to your eye, the moon appears to move ever so slightly faster than the background, and this gives the image an appearance of depth. Much like when you're in a car and objects right next to the road seem to move faster than the ones on the horizon.

 

Tom Scott has an excellent video (3:30 min) on the subject if you happen to have sunglasses nearby, which gives pretty clear demonstration of just how strong this effect can be.

I don't know the exact name, but this is a visual trick that involves the shape of the curvature of the moon at that edge (the horizon, if you were on the surface)

Essentially, if you were on the moon the horizon would be a flat line just like here on Earth, but you're looking through that horizon from far above, essentially.

u/[deleted] Dec 13 '19

Itโ€™s a composite. The moons glow would undo this effect. Itโ€™s a nice shot! But the moons light reflecting back from earth would make the stars nearest the moon lighter

u/FreeLook93 Dec 13 '19

This is all well and good, but you are not actually correct.

A decade is simply a measure of 10 years. It can start from any time. 10 years measure starting from June 19th 1876 is just as much a decade as any other span of 10 years. If you were to say "the 20th century" that would be the 20th century AD, so a measure of 100 years starting from January 1, 1901 and ending on December 31, 2000. If you were to say "the 1900s" that would be a century starting on January 1, 1900, and ending on December 31, 1999. These are two distinct things, different from each other, but both equally centuries. With decades, we do not talk about the 200th decade, no on says that, they say "the 1990s", which would be a decade starting on January 1, 1990, and ending on December 31, 1999.

So there being no year 0 doesn't actually change anything, since we don't measure decades the same way we do centuries.

u/Roar_Im_A_Nice_Bear Dec 13 '19

Yep. I had this conversation with my dad last week and we decided to check online. Here's the consensus we found on multiple sites:

  • the third millenium began in 2001, not 2000 (because there's no year zero, so the 1st millennium began in year 1)

  • same with centuries, the 21st century began in 2001

  • not the case with decades: decades were adopted later on, and begin in years ending in 0. So in a few days it will be a new decade.

Tl,dr: millenium goes from 1 to 1001, century goes from 1 to 101, decade goes from 0 to 10

u/[deleted] Dec 13 '19

โ€œYear zeroโ€ isnโ€™t really a thing. You could count the decade from 90-99 just as much as you can count it your way. Personally I think starting a decade from the whole number that represents it makes a lot more sense as far as how we refer to decades. The 20s start with 2020. The 90s started with 1990. Doesnโ€™t that make a lot more sense?

u/Daniel_A_Johnson Dec 13 '19 edited Dec 13 '19

This assertion is a pedantic to the point of not even being meaningfully true.

"A decade" is ten years. Literally any ten. "The decade" colloquially refers to, you know, the decades as we refer to them. The '80s, the '90s, etc.

I know we all had fun 20 years ago being smug about the actual end of the 20th century being 2001, and you're right that technically "the 202nd decade" doesn't end for another year, but since literally no one has ever referred to the time we're living in as the 202nd decade, you're arguing with a person who doesn't actually exist.

Edit- I've never gotten silver on a comment that was in the negative before.

This is wrong. We do not call this the "202nd decade", no, it's the "2010s". You don't say someone age 30 is in their 20s, no, that's stupid, so why would 2020 be part of the 2010s. Centuries and millenia are different as you usually say 21st century instead of 2000s, which are two different things.

u/Rcmacc Dec 13 '19

Slight different with the age thing, there is a year 0 for people (the year before you turn 1) but otherwise yeah

1

u/mudkripple Dec 13 '19

I think it's not a total consensus on whether "decades" start at 0 or 1. Milleniums most scholars agree start at 1, but since we culturally refer to decades like 70's and 80's as including their "year 0" I think the definition of decade is still up for debate.

Right? The fact that we can arbitrarily say we're in the 21st century shows that you can have your decades start whenever you want.

If you don't mind an annoying question. I'm a noob astronomer who's looking for a good entry level telescope. Any recommendations? I know most scopes at the lower level don't do much beyond looking at the moon, but I was hoping for something that it's at least possible to see other things.

u/wafflepiezz Dec 13 '19

Now imagine the possibility that there might be extraterrestrials in these galaxies looking at their night skies too

14

u/[deleted] Dec 13 '19

If you want to calculate the chances of them looking at us, you will need to work with degrees and the size of the observable universe as well as the amount of galaxies, billions is an understatement. The chances come out as literally 0. This makes me so sad, angry and scared at the same time.

The universe is just mind-boggling big and even if there is life out there, it could take millions of years to even get there with lightspeed. If it's another galaxy, billions or even more years. Just imagine putting a human into a spacecraft and start counting the years.

One of my fears is that we find life, but to send a single signal we have to wait years in both directions, imagine waiting 100 years for an answer to your question. My even bigger is, that we find it, just millions of light years away.

Anf it gets even scarier, since the universe is expanding, each galaxy will end up in its small bubble from which it will be impossible to travel to another galaxy since the space in between expands faster than you could physically go. That means at one point everything is so far away that even if we wanted, no technology could get us there. And at another point our sky would slowly turn black.

This all is hypothetical since it's billions of years into the future, but it's scary how small humans are, we literally have no impact on the "world" .

u/little_brown_bat Dec 13 '19

"It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination." ~ Douglas Adams

Keep in mind that if you could travel at lightspeed the journey from the perspective of the traveller would be very quick due to the time dilation they would experience, same goes for visitors to our planet if someone somewhere created lightspeed travel

So, there are going to be no full moons in 2020? Because, y'know, that's the last year of the decade (a period of 10 years). Or do you count from 0 instead of 1 (0 to 9, not 1 to 10)? So, that 2010 would be the first year of the decade and 2019 the last, yeah, then I guess that would make this the last full moon of this decade.

Because the Moon is too bright. If you set the camera to take a long enough exposure to capture stars, the Moon would just be a white circle (overexposed).
