It seems we may have found what the ‘great filter’ truly is.
Considering we may be on the cusp of general artificial intelligence, I think it’s more likely to find an advanced civilization that vacillates between organic and non-organic intelligent life forms dominating. Life makes ai, ai wipes out their creators, ai creates organic life and the process repeats.
Meh, I would take this with a huge grain of salt. The study has not even been peer reviewed yet.
>This would be true even if the civilization used renewable energy sources, due to inevitable leakage in the form of heat, as predicted by the laws of thermodynamics. The new research was posted to the preprint database [arXiv](https://arxiv.org/pdf/2409.06737) and is in the process of being peer-reviewed.
That’s not stopping the good folks at Stanford University, however. In a paper [recently published in the journal *Nature*](https://www.nature.com/articles/ncomms13729), Stanford researchers describe a new refrigeration method for providing cooling: simply beam the heat into space.
Referred to as radiative cooling, the process carried out by the researchers [used an experimental thermal emitter](https://www.newscientist.com/article/2116040-future-air-conditioning-could-work-by-beaming-heat-into-space/), a device which gives out more heat than it takes in. Using their method — and isolating the thermal emitter from its surrounding environment to stop heat transfer via conduction or convection — the Stanford scientists were able to lower the temperature of the emitter to 42.2 degrees centigrade below that of the surrounding air.
It’s fascinating — albeit complex — stuff, but the researchers are excited about its possible use cases. These could include AC-style cooling of buildings, harvesting renewable energy from the university, and carrying out refrigeration in arid parts of the world.
There are still challenges, though — mainly involving the cost of one of the materials, zinc selenide, and the fact that it requires a totally clear patch of sky in order to work correctly. If there are any clouds whatsoever, the heat radiation will bounce back to Earth and nullify the cooling effect.
Imagine we are drifting farther and farther from the sun. Eventually we will be where Mars is and venus will be will earth is. Climate change is inevitable.
The word “study” is doing lots of heavy lifting here.
We have no proof of the existence of aliens much less any ability to actually study them.
Articles like this would be more accurate if you read the word “study” as “clickbait bullshit” as they are simply assuming aliens will make the same mistake as humanity is currently making. Maybe the author is a huge fan of Ancient Aliens though. lol.
**Alien civilizations are probably killing themselves from climate change, bleak clickbait bullshit suggests**
Dark forest theory, meet Hanlon’s razor
We probably have no idea what alien civilizations may or may not be doing.
That checks out.
There is so much subjectivity to this study that it may as well be science fiction. This is a thought experiment with zero basis in reality.

>If energy levels aren’t curbed, this disastrous level of [climate change](https://www.livescience.com/planet-earth/climate-change) could take less than 1,000 years from the start of energy production, the team found.
if it takes zero energy to send heat back into space….

😂😂😂😂
They are assuming Aliens are as stupid as humans.
