Entering and escaping are two wildly different things.
It can enter, but not escape.

Absolutely. I don’t want to minimize the importance of the new discoveries in any way; I’m just saying this isn’t the great surprise the original post seems to think it is.

I took a physics course at a community college over 20 years ago and one of the things that stood out to me was the professor telling us not to overthink or assign too much romanticism to the idea of black holes.
His message was basically “it just means the escape velocity is greater than the speed of light… if you plug the size and mass of the universe into the escape velocity formula, the result you get back is greater than the speed of light, so our entire universe is a black hole.”
If this was being discussed at a community college decades ago then I think the new discoveries aren’t as revelatory as they would at first appear to the general public.

Yes and No.
Yes, everything increases in difficulty but the increases in difficulty are asymmetrical.
The difficulty of reversing a computation (e.g. reversing a hash or decrypting an encrypted message) grows much faster than just performing the computation (e.g. hashing a message or encrypting one).
That’s the basis for encryption to begin with.
It’s also why increasing the size of the problem (e.g. the size of the hash or the size of a private key) makes it harder to crack.
The threat posed by quantum computing is that it might be feasible to reverse much larger computations than it previously was. The caveat on that, however is that they have a hard limit of what problems they can solve based on the number of qbits they have.
So for example, let’s say you use RSA for encryption and someone builds a 1024 qbit quantum computer. All you have to do is increase your key size so that it would require 1025 qbits to crack, and then that quantum computer wouldn’t provide an attacker any benefit at all.
(Of course, they’d still be able to read your old messages, but that’s also a fundamental principle of cryptography; it only protects you for a period of time)

The problem is that you’re eating too many bears. You need more variety in your diet.
Your compost bin should be mostly green vegetables, followed by smaller amounts of fruits and grains. Keep the bears as just an occasional treat.

Also note that subsequent cooking doesn’t prevent food poisoning.
That will kill off the microorganisms that are the root cause, but it won’t remove the poison that they already produced.

It wasn’t being marketed and sold as a meme product. It was being marketed and sold as critical safety equipment.
On top of that, it was being sold during a pandemic when such equipment was being used continuously by large segments of the population.
It shouldn’t be surprising that large numbers of people bought it; the company selling it lied to those people to trick them into buying it.

Your wife is right.
Most of the signs of aging are really just the cumulative effects of repeated skin damage, and the two most common causes of that damage are sun exposure and smoking.
- Comment on In the U.S., are all voting booth areas required to have carbon monoxide detectors? 2 months ago:
Adding on to this; I’d be very surprised if there was a locality within the U.S. that didn’t require every building to have carbon monoxide detectors, but again, voting doesn’t even have to occur within a building.
- Comment on In the U.S., are all voting booth areas required to have carbon monoxide detectors? 2 months ago:
In short, no.
Voting in the U.S. is run by the individual states, and each one sets their own rules and policies.
The federal government does set some minimum rules that only apply to federal elections, but those rules don’t even require the use of voting booths: www.govinfo.gov/…/CFR-2024-title11-vol1.pdf

There’s also “Dracula Daily” which starts at the same time and is a great way to micro-dose the novel.

Get one of your professional contacts to honestly evaluate him.
You can’t objectively evaluate him since he’s your kid, and any advice he hears from you will be subject to scrutiny since you’re his parent.
If you’re right then your message will be more believable from a third party, and if you’re wrong then they will hopefully catch that.
Either way, you are right to try to set him up for success; that’s your job as his parent.

Use one hand to scoop and use the fingers on your other hand to count to ten. Then you don’t have to remember.
