Comment Re:Visiting the moon to see they Milky Way (Score 1) 26

Visiting the moon? Anybody knows you need a moonless night to get a good view of the milky way, so that is about the dumbest thing ever.

And on a lightly more serious note, the satellite constellations are in low orbit, only visible for 1-2 hours after sunset, until they are fully in the Earth's shadow.
Don't you folks have any forrest, or other natural park you can visit, to get away from the lights?

Traditional comm's satellites are in geo-synchronous orbit, which means they orbit at the same speed the earth turns. So you can point a dish antenna at them and it stays fixed in place. But that is *very* high orbit.

Starlink and Kuiper are low orbit, so low lag. But it means you need a smart antenna array, to follow them across the sky, and switch between them. Cellphones can talk to them with a regular antenna, but only low bandwidth.

EU is going in the exact same direction,

How does it work there? Australia has changed the postage and tax rules, but I still can buy cheap stuff.
Australia requires big marketplaces like Aliexpress and Ebay to collect 10% GST (sales tax) for sales to Australia.

In the past, they could post small items from China, so I paid as little as $1 including delivery.
Now they normally have to ship to Australia in bulk, and pay postage or courier here, so there is a minimum order for "free" delivery, but still only $15 (us$10) +10% tax for Aliexpress. And delivery in less than 2 weeks. Which is about the same as Australia Post parcels.

There is "no safe quantity" of air to breathe.
Every breath contains cancer-causing oxygen, radioactive particles, and maybe asbestos fibres. There is no threshold - at least no known one.

In plain English, "safe" means low risk. And your theoretically non-zero but immeasurably low risk still counts as safe. You are using technical terms to scare and deceive. Why? How does it make you feel?

Scientists have long demonstrated and agreed there's no safe quantity of lead in the body.

It sounds like you don't know what the technical meaning of "no safe quantity" is. If you did, you'd be aware that your audience does not, and would avoid it. What do you even think "safe" means?

Here is an example: there is no "safe amount of time" you can walk outdoors without possibly being struck by a meteorite. Even a walk to the mailbox, it is possible to be hit by an asteroid. Understand? The risk is proportional to time outdoors

But in toxicology, a "safe quantity" means a known amount, below which there is zero risk. The amount of the toxin must reach a threshold before any harm is possible.

So even if there is "no safe quanity" scary words used, the actual risk may be a tiny fraction of trivial. Please stop bullshitting people with technically true, but misleading words. Oh, it's your hobby?

Comment Re:Neutrinos have different weights (Score 3, Interesting) 26

And now we have a machine they will weigh them!

Not quite.
"While JUNO won't be able to measure the absolute mass of a single neutrino, it can determine the relative order of the three neutrino mass states. This is a crucial step towards understanding why neutrinos have mass at all, a property not predicted by the original Standard Model of particle physics."

So I guess that means there are 3! = 6 possible outcomes?
