I assume that the submarine producer gives stats like empty weight from which the current weight can be calculated.

However, weight isn’t the important thing in a sub. It’s the weight to volume ratio, or buoyancy.

A sub sinks when buoyancy is negative and rises if the buoyancy is positive.

There are three common ways to achieve the changing buoyancy: the most simple one is a vessel with positive buoyancy adding droppable weights until the buoyancy is negative.

Other ways are a neutral buoyancy vessel that uses it’s engine power to push itself up or down. Or a vessel that can change it’s buoyancy by filling up tanks with water (to reduce buoyancy below neutral) and blow them out with air or other gases lighter than water (to raise buoyancy above neutral). A combination of several methods is also possible.

Someone, who ridicules people for some characteristic while they are in the process of improving that characteristic, has understood so little about life.

If it had a stable orbit before and then slowed down, I thought it’ll get a more elliptical orbit, being both closer and further, or fall into Earth.

My logic was that a stable orbit closer to the center needs higher speeds to counter higher gravity and vice versa.

So if the moon would get hit in a way that makes it slow down and get pushed further away from Earth at the same time, it could keep a roundish orbit, or not?

What’s with that specific timeframe? Is it due to the orbit never being perfect? Or random slight influences from other not too far, heavy objects?

Thanks for the explanation, the moon being a little fast for it’s orbit and therefore slowly spiraling out of Earths gravity makes sense to me now.

I know you’re right, have read it elsewhere before. But I can’t figure out why that would happen. I doubt Earth is loosing mass. Does the moon slow down over time due to impacts or what causes this?

Unfortunately my hardware is too old to play games that are like that.

But I’ve noticed the same with mobile games. My policy is: if that single player game doesn’t start without internet access it gets deleted.

If you enjoy disliking Seagal, you might enjoy “Space Ice”'s movie reviews on YouTube .

It propably grabbed the info off some random number-confusing dude like me, who recently posted the Earth’s diameter would be about 6 km instead of 6000.

Edit: oops, did it again. Meant radius, not diameter…

I thought it was because proper farming.

Like being able to support larger groups of people, where individuals could specialize in other things than hunting, gathering and whatever else was keeping the early humans busy.

On the other hand I’ve heard we’ve been possibly farming long before 10,000 BCE.

Ah thanks! So you use thin metal posts. I still use self cut wood like a caveman and whack the shit out of other things.

I actually thought this was a police tool for breaking in doors.

So according to comments it’s a post driver. So far I dug holes and put my poles in. This tool seems practical for soft soil, but what do you do when living somewhere with rocky soil or with dry clay soil?

Edit: Deleted for now, cause I can’t figure out how to warn alert my comment.

Edit 2: I think I got it now. Please let me know in case it doesn’t work.

I think that’s true for only a planet with indefinite resources. We haven’t really hit many caps yet, but I believe things will start to slow down within a lifetime.

I hope I just had bad experience, but I have the aqua with backlight. About 2 years in, the display got terrible; hardly any contrast, especially in the edges. About 3 years in, the rubber buttons just crumbled away; so no more waterproof.

Can’t read anyways anymore, the contrast by now is like egg white on snow white. Didn’t mistreat, it was always stored dry and in no direct sunlight.
