The Feynman Lectures on Physics are an excellent introduction. It's somewhere between a textbook and a mass market book, intended for college students who are interested in physics, and probably STEM majors but not necessarily physics majors or have a mathematical background beyond high school.

A bit old, and doesn't cover a lot of new stuff that came out, but it's still great IMO.

So do they they live in a giant hyperbaric chamber for a few days?

Because it's looking at much brighter things than a single planet.

Radio leakage from Earth is nothing compared to the radio radiation emitted by astronomical sources.

It probably will, but it will be expensive, driving prices up further, and you'll have knockoff rhino horn pieces everywhere. Those knockoffs will reduce its ability to be used as a status symbol. Some rich person sees another rich person's rhino horn something, and they will likely doubt its authenticity, pushing the demand down, as the rich people look to other ways to flaunt their status.

There will also be people who don't care about authenticity,they know it's a sham, but nobody else has to know. If it's that much cheaper, then there's a good incentive for that, too.

And since the price of authentic rhino horn is going up even more, with poachers' profits staying the same, more and more people will be pushed out of the market without that increasing poaching rates.
