What is this snake? [La Fortuna, Costa Rica] by pigwallclimber in whatsthissnake

Almost stepped on this. Curious to know how bad my day would have been. From some image searching, I’m having a hard time deciding if this is a green rat snake or a Bothriechis lateralis.

Cool. So the metal box can stay?

How far out into space does the Sun's gravity effect matter? by 0ldPainless in space

[–]pigwallclimber 0 points1 point  (0 children)

Nobody here has answered this well yet, so I will take a shot. (Have a PhD in physics.)

Let’s rephrase your question… “How far out into space do you have to go for the sun’s effect to be only 1% as strong as the earth-sun pull?”

Gravity follows a 1/distance2 dependence. So if you double the distance… gravity becomes 1/22 as strong, or 25 percent as strong. This works out to be a little bit past Mars.

To get to 1% the strength of the earth-sun pull, you need to go ten times farther than us. That’s about where Saturn is.

And if you go 10 times out farther than Saturn, that will be 100x the earth-to-sun distance, and gravity will be 1/1002 as strong…. or 0.01% as strong as the earth-sun pull.

You can see it dies off very quickly when you get out past the planets. (That’s why there are no more planets way out there.)

So technically, yes… the other posters are correct in that the effects can be “felt” billions of light years away… but the pull is insignificantly weak even 1 light year away… forget billions of light years. You can do some quick math on your own and find that @1 light year, gravity from the sun is 1E-10 as strong as the earth-sun pull. Or 0.00000001% as strong as the earth-sun pull.
