Sunlight is available only during day. Most of the energy requirements due to lighting needed at night, have led to serious and adverse activities related with construction of dams etc. Energy due to similar fission/fusion explosion, if allowed to take place on moon can provide earth with enough energy. This would be enough to take care of the energy requirements at night. With opto-powered devices, service economy can take the global intelligence to greater heights. Planting enough saplings wuold also cause reduction of carbon emission, as they would now be used to generate more oxygen. Emissions by plants at night would also decrease.

I recently heard there are many people who believe that the moon landing was faked. I have always just taken for granted that it occured.

Do you think it was real, or not and why?

What would this do to the Earth's axis? And the seasons and precession..

Over a period of say thousands to millions of years.

At what point does downward atmospheric drag become more important than upwards gained energy from tidal friction? Would the moon be in pieces already?

What would happen if the moon were to deorbit: rings or impact event, or both?

All hypothetical of course.

How much would a half decent telescope cost? And not being too expensive. And are they worth wild, can you see much interesting things with them? Would love to get into that hobby, and feedback would be great. Thanks.

Everything's so flashy.

Like I saw Venus this evening and could compare it to an airplane which was pointing it's headlights not quite in my direction. It was way brighter than Venus, maybe -9 or something, who knows, and yellower. So if they ever had a supernova then it might look like that.
Venus is more comparable to one of the numerous bulbs they put on skyscrapers than the brightest planet.


Does it look better in the country?

I already know that hydrogen is converted to helium by fusion. That still doesn;t answer the question for me. What is fueling the sun? Why doesnt it run out. How can it stay burning without being consumed. How does it not run out of fuel. What keeps that fireball from exploding. How can it keep burining for thousands and millions of years. I have already read the usual explanation of fusion. I still want to know exactly how it can burn so long without running out of whatever is burning.
