Crikey, you seem to have produced a child-genius. Or you're making it up.

Quote from: OPWhy can I see the moon during the day?The Moon spends a part of each day visible in the sky during daylight hours
- Apart from the day of a full Moon (when it is in the opposite direction from the Sun)
- and a few days around a New Moon, when the Moon is in the sky during daytime, but we are trying to view the dark side of the Moon, which is practically invisible close to the very bright Sun.
Overall, the Moon should be visible in the sky during some part of daylight hours for about three-quarters of the days of the month (assuming no clouds, of course!).
You have posted a lot of questions that you could get a quicker answer using Google.
The universe is expanding everywhere in every direction as a consequence of the so called big bang ... what effect does this have on our solar system?Our solar system (and our galaxy cluster for that matter) is gravitationally bound and will remain so despite expansion of space. So there can be no change to our solar system due to this effect.
Which is the reason why the statement was so absurd especially when it was a NASA scientist who should know better.
Should we care? Nobody worried too much about the dinosaurs. If the end happens slowly, our descendants will get used to it, like the desertification of the Sahara. If it happens quickly, what's the problem? A bit of chemistry happened on a rock, then it evaporated.
What is the most advanced space technology you ever heard about? Today, when we are close to the crewed journey to Mars it`s rather interesting to know, what was for you the real breakthrough in the space tech world?
