Twice as hot and half as long? Yeah, sometimes it’s what’s intended. I guess my underlying point is that slower/longer and faster/shorter won’t get you the same results. Perhaps good results, but not identical.

Remember that absolute temperature is in Kelvin, not Fahrenheit or Celsius. So doubling the temperature in Fahrenheit is not the same as doubling the absolute temperature.

That cooking method is called searing. It is great for steaks.

I barely remember my basic physics but tldr look up thermal conductivity/transfer as every type of material has their own specifics of how well/rate they conduct the heat to the next object ie. deeper into the food.

No, because heat doesn’t absorb/spread instantly through food, through material. If you cook it twice as fast for half as long, you’ll get a too-hot outside and a too-cold inside.
Now… at 6,000 degrees, you’re past the auto ignition temperature of the food and parts of the oven itself. It’s going to burst into flames any moment now… I’m surprised it’s still a solid object. You don’t wanna make it that hot :-)

The purpose of the time and temperature is to cook both the inside and the outside to the desired degree. So a low temp long time gives you an even cook throughout, higher temp shorter time cooks the outside more and the inside.

Let me ask you this:
Is putting your hand in 25°C water for 25 seconds the same as putting your hand in 125°C steam for 5 seconds?

Both are not the same.
Cooking hard vegetables or meat will make the food soft and easy to eat.
Raising the temperature very high will burn the food.

Only If it actually makes you anxious. The two are not mutually exclusive, either

Why can I survive 100 tiny pin pricks, but not survive a 10 inch knife to the chest?

Give that podcast a listen if you are interested. Speculation wasn't the right word to use. Behavioral and cognitive evolution is very real, but also very fuzzy.
The strong relationship between language and music in the human brain has been long established in neuroscience through a number of experiments.
What I found to be uniquely interesting about this theory is that where we already knew that our ability to understand music is deeply related to our ability to understand language there is now a theory that explains how this relationship evolved and why that relationship has to be so.
The dopamine response to song provides a clear evolutionary benefit. For birds that benefit seems to be limited to mating. Humans are a eusocial or prosocial species. Both the ability to positively regulate the mood of other members of a society and the ability to have your mood positively regulated by others is an extremely beneficial adaptation. Extreme isn't a strong enough word. These abilities are likely hard requirements for intelligent prosocial species. Selection pressure for cooperative and affinitive behavior would have been immense. Humans have developed prosocial abilities in many ways. Ability to enjoy music is an example of one of those abilities
Understanding music would then be something that just comes with the ability to learn vocalizations, speech and language. As we evolved speech and language abilities, the ability to understand music just came with it. Enjoying music as opposed to just comprehending it is an exceptionally beneficial adaptation for a member of a prosocial species.

I don't think persistently imagining yourself dying of causes outside of your control qualifies as suicidal ideation; that just sounds like an intense and specific form of anxiety.

yeah, something about the brain only being able to process positives, not negatives. “don’t think of a blue bike” we don’t pay attention the “don’t” part

Eeeeehhhhh releasing dopamine is how 'liking things' works in general; I don't know if that really counts as explaining why our body's would come to reinforce that behavior.
For example, your brain releases dopamine on an full stomach, because it wants to reinforce that behavior, but that's not a 'why' as much as it is a 'how'. The 'why' there would be more related to the fact that from a survival POV, it's important that you eat as much as you can when you can.
We don't really have a compelling reason as to 'why' music creates a dopamine response, unless I missed something in your post.
There was a quick snippet at the end about a speculation that the same networks in your brain that can learn speech are necessarily receptive to music; which if so would be an interesting quirk in evolution that makes sense as to why it's seemingly connected to complex vocalizations. But from what I understand, that was labeled expressly as a speculation.

I think the fact that “The call of the void” scares us is the point. Like other people said, we have the thoughts to consider what would happen if we did certain things, when we realize how bad the outcome would be, it scares us. Humans are really good at classifying or naming things so we eventually started calling rational thoughts about suicidal actions, “The call of the void.” A scary name for a scary thought.

Brainwaves are not timed fetch/execute cycles like computers but that doesn't mean there's not anything to this comparison.
Computers are built from the ground up on timing. Perfect sequentialling is required for computers to function. One thing happening out of order will shut the entire system down (some exceptions). Neural networks (even when simulated in software) don't have that strict ordering requirement.
Timing of networks in the brain allows for more efficient messaging with other networks. This results in faster computation and lower energy consumption.

See my recent post. There's some incredible new neuroscience on this topic. I don't think you can say "we don't know" anymore.

>It was unsettling how quiet my brain has been.
May I ask what meds are you on, for how long and how much mg? I started with escitalopram a month and 1/2 ago, seems like I have a long way to go. OCD as well.

So if I'm understanding this right our brains are seeing modern society and all it's daily trappings as a bad bet and a losing proposition and so tells us that it's a good idea to nope out of the situation in any way possible.
This makes a lot of sense.
