This is technically possible. The cosmic microwave background, i.e. space, is extremely cold (barely above absolute zero) so it basically acts as a heatsink you can pump infinite amounts of heat into. It turns out that if you can make the food radiate heat out into space and prevent it from absorbing more heat from sunlight, it’s possible to cool it below ambient temperature. This is also a completely passive process so it requires no electricity or other form of active energy input.
The problem with this is that doing it with food might be impossible. At the moment, we can only really do it using objects with special coatings that have been optimized for this purpose.
Here’s a couple interesting videos that explain how it works:
Diggy diggy hole!
You conveniently left out the definition of “good” so you can move the goalposts if you don’t like the answers you get.
Cat in Bulgarian (котка, pronounced kotka) means eagle in Finnish.
Nope. AirPods.
They’re right there, written in big text and placed in a nice 3x3 arrangement below the jumbled mess of random letters.
I went to see a doctor today because I’ve been having diarrhea and bleeding for 2 months, based on my symptoms and the test results he thought I probably have ulcerative colitis but need to get a colonoscopy soon to confirm it. Will call the clinic tomorrow to schedule it. I also got a prescription for prednisolone so that should hopefully help with the symptoms a lot. I haven’t been able to sleep or focus on anything because I need to go to the bathroom like every 2-3 hours. Can’t wait to get a full night’s sleep again.
It’s all fun and games until you end up stuck on an ancient spaceship billions of lightyears from home because you accidentally blew up the planet.
Rivian CEO should keep his mouth shut until a few grand gets you a used compact electric hatchback (VW Polo or similar) with a decent battery.
It’s cheap and reliable.
It’s not just about speed and acceleration. It’s also about control. Racing drivers face an infinite number of different conditions out on the track and it would be impossible to tune the transmission in such a way that it does exactly what the driver wants 100% of the time. And it really has to be perfect. 99.9% isn’t good enough because the other 0.1% can wreck the car if it does something unexpected while driving at the limit.
Modern, high end race cars are automatics.
No, they’re sequential manuals*. Unless you’re talking about drag racing, where automatics are common.
*Edit: Or they can also be sequential semi-automatics if you want to be extra pedantic. But personally I’d classify a transmission based on whether the driver has to select the desired gear, or if the computer selects the appropriate gear without driver input, because that’s the thing that matters in the end.
I have history turned on and it generally recommends stuff I’m interested in. My only complaint is that it doesn’t update often enough and likes to recommend videos I’ve seen already.
Yep. 27, Finland. I learned on a manual (in the EU, if you learn on an automatic, you’re restricted to automatics only until you pass the driving exam in a manual) and drove manuals until a few years ago when my late grandma’s health started declining and her car got passed down to us because she could no longer drive.

Nope. At best, religion is a fairytale created for those who are uncomfortable with ignorance, and at worst, it’s a tool to control gullible people.
This is tax money funding toys for the parasitic criminal billionaires.
What an idiotic and short-sighted take. Research on supersonic aerodynamics is useful for far more than just toys for billionaires. Military applications, rocketry and astrophysics, for example. And even regular commercial aviation, because supersonic shockwaves are a major source of drag even at the speeds airliners fly at. Airlines would kill to have a fleet of planes that burn a few percent less fuel.
E: Also, much of the noise an airliner makes during takeoff comes from the sonic booms created by the engine fan blades going supersonic.
I hope you realize that floating objects generally orient themselves in such a way that the most buoyant parts are at the top. So while you could float around, you would be hanging by your balls the entire time…
