    Most of the light would not be reflected toward the Earth.

    Yes.
    But we already obtain light on Earth at night from the moon, without mirrors, so I'm wondering why you think that we might want more light at night.

    A better idea would be to simply paint the Moon white. As is, it's charcoal grey, although it doesn't look like it in the night sky.

    Is the question to do with installing solar reflectors on the Moon so that these could provide an additional energy source for Earth?
    If so then yes it's possible from an engineering point of view, but pointless because very little of the light already reaching the Earth from the Sun is utilized directly as an energy source.

    coz...surface of moon is rough so it is not reflecting properly sunlight but with mirrors, we can obtain it at night which may plays an important role in food chain

    The position of the moon with respect to the earth is not fixed. At some times during the month, the moon is actually located on the opposite side of the earth from the night side. What will you do with your mirrors then?

    I suppose it would work, theoretically.
    We discussed telescopes on the Moon, which is basically your idea on a smaller scale.

    The biggest "selfie" mirror ever?

    yeah!!! As people have much craze of selfies these days ...so it will work in better way :)

    Goodness! Why would you want to abolish nighttime? That would screw things up beyond all recognition...

    lot of sins take place at night...Probably we achieve peace on Earth :)

    Or as Black Sabbath put it: The moon is just the sun at night

    Yes, many nocturnal animals might go extinct.
    That would be a shame.

    Sin is a 24 hour a day business. I think that having no day/night would make things worse, not better. :oops:

    I agree with you, day and night is a natural phenomena, if we broken up this, Life on Earth is to be broken,that will be horrible.

    If we could significantly increase the amount of energy we receive from the sun, wouldn't that increase "global warming"?
     
  19. Sep 17, 2015 #18
    It wouldn't increase the greenhouse gas effect as such, but still the extra heat would accumulate, so that would add extra heat on top of existing global warming.
    It would not only affect long term climate trends but would completely change local weather patterns, I would expect this resulting in the complete loss of polar ice in a short timescale.

    Sins? Like watching adult TV? Or even turning on the electric lights according to some religious varieties.
