Weekending at Bernie’s is not solely an American tradition, it has historical roots to the beginnings of recorded history across most every culture. If the current ayatollah is a vegetable then the groups in control have the same justification as they just saw colleagues and senior people wiped out and this did not endear them to America. Instead they will pursue destruction of the rest of the world, no matter if it’s halting oil traffic with drones and mines or developing nukes if the world no longer has that as a choke point.

I doubt they used a single new technology or device to find this airman. There is satellite and AWACS coverage. Iran downed one but 2/3-3/4 of our AWACS are there.

Of course, but on the flip side they are always given “cool new gear” to try out. Even if the satellite showed where they were, if they were unconscious in a 10’ radius somewhere under stuff it’s not inconceivable they used a new widget to help with the final inches. The reality is these stories are just psyops to embellish capabilities and to distract from real life limitations.

It is not clear that the CIA wanted to advertise this. At least from the blurb, all we know is that la Presidenta and his goon Ratcliffe could not keep their mouths shut. Having his goon as head of the CIA is a security problem from the get-go.

I have some experience with SQUIDS and while you can do some cool things with them the idea you could isolate a human heartbeat beyond a few yards or meters is nonsense. It might make for a cool urban search and rescue tool for locating an unconscious body a few feet away but you aren’t locating a single human heart beat from 50 miles away in a search area of 10,000 square miles. Sure, they used some new widget(s) to find them but this story is pure BS.

We wouldn't buy a 100 # bag of dog food, open it in the corner and let the dog feed itself--it couldn't do it.

Ive had two dogs that would refuse to eat too much dog food, they weren’t the eat now ask questions never type. I always refilled a large bowl and they always had food but neither were overweight. They both were very picky and preferred human food and on the rare occasions they got some or stole some they didn’t have the sense not to stop eating when full and kept eating stuff that made them sick because there are so many things dogs can’t tolerate that we can. One of them even ate American toads despite having to immediately barf them up in a bath of foam because they are mildly toxic, though after maybe the 20th time it learned. So the problem could be in that todays food is highly unnatural in that it’s incredibly nutrient and calorie dense, is extremely tasty, is cheap and available almost instantly everywhere and people just aren’t equipped to deal with that.

Metabolism is one of the most complex functions of the body and we don't know much about it. We're constantly learning new things.

Just to add, I have the opposite problem in that I have metabolism issues where I can eat insane amounts of calories and not gain weight. Right now I always am trying to eat more than I’m hungry for, probably around 3k+ calories per day and I’m old and moderately active certainly not some kind of professional athlete. My body fat is around 7-10% (it makes me look grotesque and bizarre) and I have a bmi of about 19 which is very close to underweight. When I was younger I used to make people very angry by eating 5-6k calories per day with the same body fat though I was a bit more active then and had more muscle but not some kind of extreme athlete where its justified. Not being able to gain weight and needing to eat extra food is not a good thing, it makes me look very different and gaining muscle is harder for me than it probably should be. There are likely all kinds of things this puts me at risk for, not to mention that our ancestors didn’t exactly live through rough times if they have metabolism issues like that.

Yes, that’s wrong everything goes in. I was trying to emphasize that originally mass and energy were simply less distinct because of how the boundary to the problem was approached. Put simply the energy intrinsic to the particle or system itself wasn’t thought of any differently than particles whose energy is completely relative like photons. The only difference to today is just how the math is arranged.

E=mc^2 is a special case where the relative velocity of target and observable or two points is zero. You need to introduce an energy term for apparent mass gain from velocity just like you want to create the stress energy tensor in two parts one with light speed momentum particles and one for mass based relativistic particles. It’s not wrong to just not care which is which if you account for it correctly, but separating them into parts depending on if they are intrinsic to themselves at least in part or purely relative is useful for intuitive understanding and keeping things neat in terms of energy and momentum.

The "shitty life choices" that cause harm are what make life fun and worth living.

100% as long as you don’t suddenly change your mind about taking full responsibility for your actions when suddenly what all the statistics say is likely to happen, happens. With a for profit insurance medical care system this means saying too bad and letting you suffer or die. Without a home because you can’t work anymore you get thrown to the streets where we all have to deal with you for up to several years before our problem goes away. If we had a system of say medical care for all, very modest but safe public housing for free in the same area you are from, and a very modest basic income to cover some things with actual robust food shelves providing adequate amounts of basic nutrition like beans and rice for free this would not only allow you to make those choices with less severe repercussions on average and at the same time, remove our problem in having to clean up a pound of mess when the cure was just a pinch.

Wouldn't you have to be on the very edge of the universe to feel ancient gravitational waves? It's not like they bounce like sound waves.

There is no edge, every point is at the precise center including your two eyes. Because light, gravity waves, and causality travel at a single fixed speed, the further something is the farther back in time it is until you reach a point where you cannot see beyond because it is too far back in time and approaches the Big Bang. Gravity waves from the Big Bang will be rippling through all points always just as you can look in any direction and see the microwave background which is the Big Bang but stretched out to the point it’s far cooler and of longer wavelengths.

And don't they dissipate the further they get from the source, making them undetectable?

Gravity waves are fundamentally undetectable, even in principle. If you want a nearly exact example you are probably familiar with think of two floating bits on a still lake. Perception only occurs along the surface of the water, they cannot see or measure or perceive up and down. When a ripple passes the two bits move toward and away from each other as the surface stretches and shrinks to accommodate the wave and that is the distortion that is measured not the wave itself. It boils down to the second derivative of the mass quadrupole moment tensor and it falls off linearly with distance so is not like other directly measured waves that fall off exponentially.

And how does this explain the ridiculous notion that matter traveled faster than the speed of light shortly after the big bang?

The universe is the same everywhere at the largest scales including being at the exact temperature despite not being casually connected if you look at how causality works on our scales, times, and energy levels. The most reasonable thing is that the universe was once all touching in close contact, even points 90 billion light years away from each other. The universe is also expanding the same everywhere on the largest scales so if you rewind time everything goes back to one point even if there isn’t a “center”. So the crazy thing is to look at all the evidence for it (many other examples of measurement also confirm this is how it looks) and say it’s all wrong because it does not meet personal expectations. That’s not how science works.

Forgot to add above that similar to a contained gas having increased rest mass with increased temperature if you have a 100% reflective box and put even one photon in it the box is said to have increased rest mass while if you release it from the box it is not said to have rest mass. Clearly the photon is unaltered and the difference is the box isolates it from the greater system although this is an arbitrary distinction it clarifies how the problem is framed and that’s why its convention.
