Thanks, saved me a click.

What’s wrong with veritasium?

The problem I have encountered is that some of the physics explanations are of dubious quality. A good example is the debate between Veratasium, Steve Mould, and ElectroBOOM about “whether electricity travels at the speed of light.” The Veratasium video comes across as pretty clickbait-y. That said, the combined narrative across these three channels was pretty interesting.

After watching the video I was a bit surprised to not see them explore the possibility that the word "heartbeat" may not refer to an actually human heart, but rather the concept in similar way that computers and servers uses the term heartbeat. The US military can have a low energy transmitter that sends a heartbeat signal, but which methods of sending/receiving isn't disclosed to the public.

I would look if there is anything close to the idea of an "magnetometry" that could be used for communication with an sender and a receiver. Something like say the idea expressed here https://onlinelibrary.wiley.com/doi/full/10.4218/etrij.2023-...

I can manipulate space-time. Enter the on ramp to the highway and accelerate. I am now aging slightly slower than you are. I can also manipulate gravity by charging my phone. Since E=mc^2 my phone weighs slightly more when charged.

Hey, I saw your comment on my suggestion of switching to drama instead of switching animals on the cocaine bear thread and just wanted to correct an apparent misunderstanding of meth. I can't comment over there any more because I missed it for too long so I'm doing it here, which I hope isn't so against the rules as to annoy anyone. Meth is both excreted and metabolized and then the metabolites excreted in urine but…

Uhm... Hm...

This person is a meth scientist? What . Okay. Don't want to know.

They want to lie about how they found the soldier, and potentially have China spend a few billion trying to copy technology that can never work.

Militaries and their disinformation units are like this. There are at least 5 different narratives about how the US found Osama bin Laden, which contradict each other : https://en.wikipedia.org/wiki/Killing_of_Osama_bin_Laden#Alt... When a military achieves something and there's intense speculation on how they did it, they will want to obfuscate how they did it. One of the best ways to do that is to give a range of d…

Why is everyone debating some theoretical advanced heartbeat or otherwise people detection tech rather than the absolutely obvious answer - some kind of advanced, specialized transmitter that's designed to be hard to detect and simply transmits the encrypted GPS coordinates of the pilot?

I think the fear of being located isn't based on the fact that someone can decrypt an encrypted transmission, its simply because someone can trace that a particular location is transmitting some radio waves.

You encrypt it because encryption is cheap and gives you confidence that the message content won't be intercepted.

The transmission itself would need to be stealthy or separated (by distance and/or time) from the pilot. For example, the pilot might leave a transmitter to send a message "moving south, will hide on X hill" hours after the pilot leaves, or even toss a transmitter into a river. But most likely just very spread-spectrum/CDMA to make it indistinguishable from noise.

Because the NY Post ran an article that said "The CIA used a futuristic new tool called “Ghost Murmur” to find and rescue the second American airman who was shot down in southern Iran, The Post has learned. The secret technology uses long-range quantum magnetometry to find the electromagnetic signal of a human heartbeat" Note, I agree that it was probably some novel beacon technology. Just answering your question abo…

I get the NY Post article, I'm just surprised that even people who assume the Post is full of shit still run after the "heatbeat" claim rather than ignoring it completely.

More likely, the story is designed to make the public believe that US propaganda is actually aimed at the "foreign adversary" rather than at the US population. The emotionally appealing bit is the idea that even if the story is fake, Iran is now thinking it is dealing with an adversary that has and is using tech that is right out of science fiction. In reality, it's all aimed at us, the people. All of the "tough talk…

> More likely, the story is designed to make the public believe that US propaganda is actually aimed at the "foreign adversary" rather than at the US population. Or some kind of cover story to distract from the real technology. If they really used some kind of advanced beacon, but they can convince people it's actually some kind of crazy-advanced heartbeat-detector, they can discourage their adversaries from looking…

> discourage their adversaries from looking for the beacon signal

I thought the exact same thing the moment I saw it. LPI (low probability of intercept) beacon just makes so much more sense (in the kit the pilot ejects with... has existed for decades). Why would they bother detecting heartbeats? They might not even detect the right one or trigger on an animal or whatever.

Hey I am not shaming you. You do you okay. If the apocalypse ever happens we will need people like you.
