I wonder if we would feel the sudden disappearance of the centripetal force of gravity.
Gottem. :)

After 8 minutes

Yes, the tidal effect of the sun would disappear, and that would probably make the oceans all fucky suddenly (after an 8 minutes lag).

Does gravity travel at the speed of light?

After 8 minutes, almost certainly

I wonder how long before you would feel it becoming colder
Evilsandwichman@hexbear.net 3 months ago
Forget colder, I kind of feel like we’re missing out on not hearing the sun thanks to space
jjagaimo@sh.itjust.works 3 months ago
But not by much longer. People on the other side of the world or connected to satellites monitoring sunspots would notice pretty much immediately after the light ceases to reach the earth
affiliate@lemmy.world 3 months ago
yeah but everybody else would be sleeping so it would still take longer

If it happens at night it will probably take 5 or 6 seconds longer for people to start seeing the first messages on the internet

The telephone: “Am I a joke to you?”

Who would leave their sound on in the middle of the night?

But will we feel the shift in gravity as the planet starts moving straight?

Wouldn’t the planet rapidly start to cool? I think we’d be dead by morning
philthi@lemmy.world 3 months ago
Doesn’t the earth itself provide a significant amount of heat from the core? I’m sure I read somewhere that for something like every 10 meters down you dig, the temperature raises by 1° celcius. So maybe we’d not notice a temperature drop so quickly?

The surface would eventually freeze over. But some life would almost definitely survive deep underground and underwater, near geothermal vents not unlike those that hosted the first lifeforms on Earth. And, maybe, in some billions or trillions of years, Earth would stray near another star system, get captured by its gravity and slowly thaw out, restarting the evolution of life.

Not sure how quick exactly, but the earth doesn’t provide enough heat, not even close. I think Kurzgesagt has a video on this subject, pretty sure without the trillions of joules of energy showering the earth every second we’d get awfully cold awfully quick
rockerface@lemm.ee 3 months ago
Atmosphere would hold the heat for a bit, the real issues will begin with food shortages because the crops won’t grow
bobs_monkey@lemm.ee 3 months ago
Yeah but how long is a bit? Also, without the gravity center of our solar system, how long would it take for all the planets to start drifting off into the void?
Psythik@lemmy.world 3 months ago
The core is still hot. If we bury ourselves deep underground, there is a chance the humanity could survive for thousands of years without a sun. If not humanity, then some sort of life will survive long enough for future archeologists to find it millions of years later.
But don’t quite me on this; I’m simply reciting from memory something I read in National Geographic or a similar publication 10-20 years ago. IDK how true this actually is.

False; no sun = no morning!
burgersc12@mander.xyz 3 months ago
So extremely cloudy mornings = no morning? lol just kidding!

The moon also doesn’t emit it’s own light. It would take longer for the moon to “disappear” than it would for the sun but it wouldn’t be the whole night.
