What's faster than satellite communication? Neutrinos baby Not even sure if that's worth doing, either create/emit or use encode data into them as they fly by to be received by someone else Edit: that's cool people have tried though

We already do, so the conspiracy theory goes. In Antarctica

Neutrinos can go straight through the Earth, yes, but since they have mass their velocity is less than c.

It’s very close to c though, close enough that it beats sending a signal around the Earth.

The drawback is the impractical size and cost of a receiver.

So, according to basic Ant-Man theory, if I were hit by one of these, it should be like getting all that (10% of a) ping pong ball energy concentrated in a tiny spot, causing me to fly backwards across the room?

I would expect it to be more likely to punch through skin than to actually propel you. But also neutrinos don't typically collide with things very easily, they're more likely to pass through you without you ever knowing.

Yeah there's no way it would be able to grip onto anything, probably more like the Bugorski case, where he stuck his head into a particle accelerator and a proton beam went right through his head.

This particle spread this energy through a volume of seawater a few km deep in the Mediterranean. It's going to raise the temperature of that volume a few billionths of a degree, if that. So, no, we can't.

What if our existing solar panels are optimized to detect these? Then will it improve the quality of solar panels to capture more energy from sunlight as well? Sorry, I'm no expert in this - asking more of a curiosity.

There's nothing to optimize here, neutrinos just interact very very weakly with anything else because they don't carry charge (so no electrical interactions), don't carry color charge (so no nuclear interactions), don't carry weak charge (so no weak force interactions) and have tiny tiny masses, but they are still bosons (so don't act as field carriers like photons do, they're just regular matter). Their low chance of interacting with matter is a fundamental property of them, there's nothing you can do about it through technology, just like you can't create heavier electrons or weaker quarks.

I was thinking the same though. It doesn't interact often, but if it randomly does annihilate with another particle in your body, at such a small scale (subatomic) that force/pressure just destroys anything in its path no? Like a paint flake hitting a space ship. Or is it more like "light" (since they're iirc their own antiparticle), which is then absorbed by surrounding matter and turns into heat?

In the wrong spot, this sounds to me like it kills you?

Nothing to be afraid of, of course, for the reason you mentioned. Just wondering, xkcd "what if" style

One of the lead researchers in KM3NeT mentioned that the particle was emitting 2 horse power in light during detector transit. A typical body builder expends about 1 horse power while performing, so its 2 body builders in a single particle.

Fun fact, a typical horse exerts about 1 horse power of usable work while performing. That's so weird, I'm sure almost no one would've been able to guess that - but it's true. (To be clear, that's sustained effort over time, not just momentary. Athletically trained humans can do about 1 HP of peak momentary effort, and around 0.3 HP if sustained over time.)

Track cyclists (sprinters, world class) do 2KW+ peak for a few seconds at a time. That's potentially ~3HP. (and while doing so, average more than 70kph over a 200m distance)

So, 2,000 milliSchwarzeneggers if we use SI units?

Yes, but please observe SI rules [1]: it's millischwarzeneggers.

> This means that they should be typeset in the same character set as other common nouns (e.g. Latin alphabet in English, Cyrillic script in Russian, etc.), following the usual grammatical and orthographical rules of the context language. For example, in English and French, even when the unit is named after a person and its symbol begins with a capital letter, the unit name in running text should start with a lowercase letter (e.g., newton, hertz, pascal) and is capitalised only at the beginning of a sentence and in headings and publication titles.

Isn't Ant-Man logic that he still has the same mass when he shrinks and, as such, can generate the same force? Unless you get thrown back by ping pong balls normally, I think you'd be fine.

And yet when he grows he still has enough strength to punch a leviathan out of the sky. I'm not sure there's such thing as ant man logic - It doesn't seem like it should result in strength both ways.
