The Shortest Day ...

[jaF0]

... is upon us.

 

[jaF0]

It's all uphill from here.

 

[AlpineFresco]

Happy winter salt tits everyone!

Wait, no...

 

[jaF0]

Oh, by the way. It's Winter.

Or Summer.

 

[SassySheDevil]

Summer. I’m boiling hot laying in bed in my knickers trying to sleep. The air won’t move.

I've always wondered about the opposite of us. Weather. Is it weird to celebrate Christmas when it is hot?
I've been in Arizona before at Christmas time, and it was in the 70s. That was so weird to me.

 

[jaF0]

Y'all's a bunch of poopieheads.

Aren't all days the same length? I thought the Earth rotates at a steady rate.

 

[AmberLGreen]

Aren't all days the same length? I thought the Earth rotates at a steady rate.

I have always found there are some days the Earth moves and other days not so much

 

[munch2much]

Aren't all days the same length? I thought the Earth rotates at a steady rate.

Ah length of day is about earths orbit and it’s angle to the sun. Rotation is a different thing

Ain't that the truth.

You lost me.

 

[AmberLGreen]

Ain't that the truth.



You lost me.

Lost in space?

Isn't the length of a day one rotation of the earth?

 

[saustin5432]

Lost in space?

I didn't know you knew me this well.

 

[jaF0]

I have movement on most days.

 

[jaF0]

Ah length of day is about earths orbit and it’s angle to the sun.

I think that's called a year.

It depends on who you ask. Most people would say the length of a day is 24 hours, although that is not quite precise and is the reason we have to add a day to the calendar for Leap Years.

Others would say it is the length of one rotation of the Earth, but even this varies. Sometimes the Earth's rotation slows down due to the sloshing about of molten magma inside the Earth's core or by the release of it from major volcanic eruptions. Gravitational interactions with the Moon and with other planets also affects the Earth's rotation. The accumulation of cosmic dust adds thousands of tons to the mass of the Earth every day, which constantly slows its rotational speed. Even major earthquakes can noticeably affect the Earth's rotation. All of these effects are minor, but they can be measured with precision atomic clocks and they do add up. They are the reason scientists add a Leap Second to the world time standard almost every year.

When people talk about the "shortest day of the year" they are being colloquially imprecise. But everybody knows that what they mean is the day with the shortest amount of daylight. And that day does indeed fall on the Winter Solstice (today), if you live in the northern hemisphere. In the southern hemisphere, today is the Summer Solstice, and hence the day of lengthiest amount of daylight for the year.

Happy Solstice Day!

[AmberLGreen]

Ben I think I love you

 

[ericalauren]

Happy Yule, bitches! I hope everyone is having a lovely day. I was sad today and had to take a small dose of Xanax. Got to love that SAD.

 

[mynameisben]

What I think is really weird is that the features on the Moon appear upside down when you look at them from the southern hemisphere if you're used to looking at them from the northern hemisphere, and vice versa.
