My brother had a big well HUGE Oxycotin addiction 20 years ago, he was a snorter, is there like an equation to calculate what percentage is he at risk to reuse? He has gone so far as telling his doctor, dentist, psychologist, He has to make an appointment for the hospital to put down his past opioid addiction so he will never get treated with it. He has gotten in his head that if he ever gets knocked out or in a car crash or whatever that he is going to wake up and find morphine being put into him and doesn't want that. And his doctor has no relationship with the local hospital. He would rather deal with the pain and everything instead of going back to being an addict and doing it cold turkey again. That is the reason I am asking to put his mind at ease. Cause his appointment is not until 2 months down the road for Medical Records. So he is taking everything overboard at times. Or is there a better community to ask this?

The Cosmic Microwave Background is 13.7 billion years old, yet is currently located at a distance of 46.5 billion light-years. It was emitted when the Universe was around 380,000 years old, the cosmological redshift of this Cosmic Microwave Background is approximately z = 1100, meaning the Universe has expanded 1100 times in size since what we can detect, was emitted. We see these figures all the time.

But what about the Gravity Wave Background emitted at the very instant of the Big Bang, or the Neutrino Background one second later? If we can ever detect the very first gravitational wave of the Big Bang, how much further is the radius of our Detectable Universe pushed outward?

Hilbert imagines a hypothetical hotel with rooms numbered 1, 2, 3, and so on. The hotel is full and new guest arrives wanting a room. I can not move any guest. So i say to new guest wait 1 sec a new room must become available as Infinite guests one must leaving at any time.

is this good answer?

I follow this scientist on YouTube, he's made a very interesting series of videos and is looking for a research grant, here is a lot more context: https://www.youtube.com/watch?v=fvxNmStSC3M

tl;dw

1. We've been pumping a shitload of CO2 into the atmosphere for the last 100+ years

2. It seems extremely unlikely that the global CO2 emissions will go down in the next ~50+ years

3. Even if the whole world became Net-Zero tomorrow, The planet will keep warming because the extra CO2 already in the atmosphere will stay there for the next 100+ years

4. Carbon capture is basically impossible due to economics

Now here comes the scary part that that you maybe need a open mind to consider a good idea.

By adding 3% "Baking Soda" to jet fuel, it would reflect heat away to counter global warming, and would drop out of the air in ~1 year, so we can stop at any time.

Before forming a strong opinion and just down-voting let's have a constructive conversation in the comments. Even better, please watch the video

This seems like an actual viable option to buy us time to fix global warming, because what we've been trying hasn't been working nearly fast enough.

Does this effect have a name? I'm specifically referencing the iridescent shapes to the lower left of the apple

This memory randomly came back to me when I woke up in the middle of the night and it's been bothering me since. When I was a kid in the early 90s, I remember telling my dad about a rocket concept where the rocket would scoop up dust and gas from the space environment around it and use that as a propellant. His response was to make a face and go "cool" and that was the last time I thought about it. I think I might have seen it talked about in a library book and have a vague memory of a cartoonish illustration of a rocket with a funnel on the front.

At the time, the concept exited me, but it felt like a really long stretch to make something like that work. I haven't really thought about it since. Is this concept still bouncing around? It doesn't really sound that viable, but I don't know crazy ideas sometimes work.

It's like a cross between a bumble bee and a hummingbird, with dragonfly wings. SE WI, USA. I've lived here most my life and never saw it until now

It makes sense from a why standpoint. I can't help but wonder about the how.

How did we evolve reproductive organs that are not only sensitive, but also release reproductive cells at climax?

I'm ok with a "we have no idea" answer, but if there is an answer I also want to know.

I have heard that a very hardened alcoholic can get alzheimers and never know they were a drunk and don't feel withdrawals from it. Is this true? If it is then that would mean a certain portion of our brain or body can ignore the withdrawal symptoms. What part of the brain is it, and how come they don't feel the serotonin release anymore like when they were drinking. Or is it a lot or small amount of serotonin or dopamine? With that said then is the complete opposite true? Can a person trick his or her brain into getting drunk without ever touching a drop of it? Do the same parts of the brain then function like it would a person who get;s "high". Can try to explain further if any questions.

Disclaimer: I know enough about astronomy to know that I know pretty much nothing.

As dark energy was explained to me, it is a placeholder in the equation(s) for measuring the expansion of the universe. Rephrasing, we know the universe is expanding but we can't account for some amount of the force involved.

I hope I am making sense and I am not too far out in the weeds.

To my question: all of the stars are blasting out not just photons but also substantial amounts of physical matter in various states (gas, plasma, solid) that also includes material from the various objects in the solar system (eg atoms of water from mars). Wouldn't that mixture of massless photons and physical material have some significant influence on everything else?

Considering that cats are descended from big cats like lions
