It's this meme all over again but this time it's Israel vs. Russia.

... and neither does the author (or so I believe - I made them both up).

On the other hand, AI is definitely good at creative writing.

Wherever it comes from, sex must be pretty old. Am I correct in the assumption that all Eucaryotes do have the ability to have sex? (ofc with minor exceptions)

I specifically miss my philosophical and spiritual communities from Reddit. I love learning about mythos and different religions, especially the more esoteric stuff, as well as political philosophy. That content just isn’t here in the same way (or sometimes, at all). It would be amazing to have that here.

If you speak german, that is what the community !philosophie@feddit.org is all about.

No, I think it makes sense.

Living organisms use ions internally (positive charges) because they produce something (like fruits).

Technology uses negative charges because it harvests those fruits, and takes them away (negative).

Yeah, I predict that in the future, you can't expect that content on the internet is written by humans. If you go to the internet, then it will probably not be to connect to other humans. Maybe you want to know something that a bot can tell you or you have some administrative task to fulfill, like filing a form.

All life is based on large quantities of Water. The same will be true on Mars. There has to be a major and reliable source of water on Mars.

What options are there? I read an interesting article yesterday that said "Our results show a two-order-of-magnitude diurnal variation of water vapor pressure, suggesting a strong atmosphere-regolith interchange", in other words, the soil on Mars extracts water out of the atmosphere in the nighttime and releases it in the daytime. This means that if we collect the soil and "bake" it, it would release water vapor in a controlled environment. We could then condense that water vapor to get useful/useable water.

Hear me out. This thought process requires a bit of knowledge of physics/chemistry.

On the martian poles, there are vast quantities of frozes CO2. This frozen CO2 exerts a certain "vapor pressure" - in other words, a certain partial pressure of gaseous CO2.

Now, if we convert this CO2 into O2 by removing the carbon out of it, the concentration of O2 in the atmosphere increases. And therefore, the concentration (and partial pressure) of CO2 decreases.

But since the frozen CO2 on the poles causes a certain partial pressure of CO2, a bit of the frozen CO2 will go into gaseous phase to refill the CO2 partial pressure.

So, by converting CO2 into O2, the concentration of O2 increases, but the concentration of CO2 stays approximately the same. As such, the total pressure (and density) of the atmosphere increases. This would happen if large-scale biological photosynthesis/growth took place.

Any thoughts?

Does anybody have good data on what radiation exists in space?

I have found sporadic information, such as on Wikipedia but I wonder whether there's nicer, clear structured information on this topic?

I just wrote this article and I would like your comment:

The Universe Will Not Die a Heat Death

We assume that the universe is expanding according to the Lambda-CDM model with a fixed Lambda constant.

Imagine a central star, like our sun. Two artificial satellites are orbiting this sun in circular orbits in opposite directions. As the universe expands, the orbits of the satellites are elevated, and the satellites thus gain mechanical energy (the sum of potential and kinetic energy). This energy can be released by causing the satellites to collide or by simply having them graze each other. As a result, some of their kinetic energy is converted into heat, which can be radiated away as thermal radiation, and the satellites descend to lower, more inward orbits. The process can then begin anew.

Hi there, I'd like to connect with people to discuss technical aspects of settlement of mars.

I'd look at a house on earth and ask: what things have to be supplied from the outside; what things can be produced inside the house? Houses on earth have piping for water, and cabling for electricity.

Plants can be grown in a green-house using these two ingredients, and the people can sleep in a spaceship.

Comment whatever comes to your mind.

TIL: PeerTube (lemmy.world)
submitted 3 months ago by nikaaa@lemmy.world to c/solarpunk@slrpnk.net

There is a decentralized YouTube alternative.

Video hosting is notoriously expensive. PeerTube circumvents this problem, because videos aren't stored on some single server, which would cause high bandwidth cost for the server operator, but largely by the users after they watched them, similar to BitTorrent. This way, the cost of video hosting is distributed among the clients, by using their internet connectivity for sharing.

I believe that PeerTube is an interesting project, and I'd ask you to check it out. It's cool.

Similar to Lemmy, it's not a single running server, but rather a software that can be used to set up a server. So there's many instances. I'm still exploring which instances are interesting. If you have any recommendations, I'd like to hear them.

I cannot explain why but I feel that this belongs here.

What is shown is some kind of re-interpretation of the "princess and the pea" saga. Instead of showing the princess' over-sensitivity to small things, it displays the princess' love for plants and nature. In this way, sensitivity is interpreted and seen as something positive, which I can appreciate.

Tell your republican friends/colleagues/whatever that solar panels are a good thing because they let Jesus into our lives.

Hopefully that will accelerate the green energy revolution.
