A radio telescope on the far side of the Moon would have the advantage of being shielded from all the radio interference from Earth.

I'm not sure that there are any advantages to placing an optical telescope on the Moon rather than in space.

No. We might have fusion power plants within a few decades, but those will use deuterium and tritium as fuels, not Helium-3. Helium-3 fusion has some advantages, but it's more difficult and it might not happen within our lifetime.

Less than 1%. For every star Kepler has detected a planet around, there's a hundred more stars in its field of view with planets it can't see.

The crew would be risking something like an additional 1% chance of cancer in the next 30 years. While the radiation dose is significant, it's an acceptable risk.

Also, Gliese 581g is unconfirmed, and there is a lot of doubt about whether it exists.

The orbital plane of planets in a given system is random as far as we know, and not related to the plane of the galaxy. Our own solar system, for example, is tilted more than 60 degrees from the plane of the galaxy's disk.

So as you might expect, more than 99% of all planets in a sample are undetectable by this technique. Kepler has been so successful because it is watching about 150,000 stars at once, all in an area of sky that would be covered by your fist at arm's length.

How long ago it happened is irrelevant. It really is just the distance that is keeping us safe.

Doesn't "is operating" mean it's only illegal if turned on?

27602. (a) A person shall not drive a motor vehicle if a television receiver, a video monitor, or a television or video screen, or any other similar means of visually displaying a television broadcast or video signal that produces entertainment or business applications, is operating and is located in the motor vehicle at a point forward of the back of the driver’s seat, or is operating and the monitor, screen, or display is visible to the driver while driving the motor vehicle.

Isn't Glass always turned on and waiting for user input? Does "is operating" mean the device is powered even if it's not doing anything?

These are some of the things the courts have to figure out.

Parent was probably referring to @outside1234's assertion that dash-mounted monitors are illegal even if turned off.

It's not, it's slightly larger and more massive than the Sun. Only the outermost planet is within the habitable zone, but it's a gas giant.

Because the timescale of the universe is much longer than the timescale of human civilization or intelligence. The odds of any aliens we meet being at the exact same level of development as humans (to within ten thousand years or so) despite having evolved independently on a planet billions of years old, are extremely small. In the vast majority of cases they will be millions of years more advanced or millions of years less. As chimps don't build starships, it follows that almost every interstellar civilization we find will be godlike compared to us.

In other words, we are a newborn intelligent species, and newborns generally find that everyone around them is older.

You're assuming that being older implies having more capabilities. Civilizations like ours almost certainly reach limits, either in terms of resource limits, or in terms of fundamental limits on the kinds of things that can be engineered (or both). The fact we've never run into any alien tourists or explorers, despite thousands of years of record keeping and being able to search the earth for alien artifacts, and our own research into star travel support the idea that it's impossible.
