with materiels on hand in universe attract materiels use of gravity to hold planet where it is how would materiels be assembled if possible make planet introduce cellular life create lifeforms that create advanced life through cellular reproduction possible to figure out or do experiment if scientists were to explain if this is not possible why so that question will be answered so anyone who is curious about how evolution can be known when we were not there . also throgh use of cells create whole animals which could generate more animals with exra cells also for humans to reproduce through exchange of cells not cloning exchange of cells. possible to work with materiels on planet to create humans by assembling cells. make as many types and design for as many ways to reproduce as possible possiblethis done so long ago people forgot it was possible then outlived science then denied it was possible . same happen again historical records humans destroyed humans become fairy tale.

I know that the sun has an absolute visual magnitude of 4.8. I also know that it has a total luminosity of 3.84 x 10^26 W.

I also know that its luminosity in the visual band is 4.44 x 10^25 W. Can someone explain how this figure is derived from the total luminosity and magnitude? What equations do I need?

Are satellites more important than contamination or magnetic field disturbance?

If we are willing to pay the price of going to the the moon to get it:-

http://www.bbc.co.uk/sn/tvradio/programmes/horizon/broadband/tx/moonsale/

it will be fusion reactors all round won't it?

Or will we have World War III squabbling over who has right to what?

Isn't it worth getting it right this time, because fusion power will give clean and virtually limitless energy to everybody - 'we can have our cake and eat it' - can't we?

Surely the balance of power is going to be a lot more interesting this time round, because the Russians have got clout and now so also do the Chinese - wouldn't you say?

For once the Americans are going to have to learn the meaning of the word HUMILITY - that's assuming they can spell it! Probably be more like HOOMILETY or some such rubbish!

Well..Jupiter is a all gas planet...so how come shoemaker-levy comet left craters on the surface of Jupiter?? To leave craters, don't the planets have to have a rocky surface?? How can there be craters in the surface where there's nothin but gas?? Shouldn't the comet have penetrated the surface without leavin any craters??

Thanks..

Hi, I homeschool my boys and we have a few more questions which we hope someone can answer.

1. We have telescopes in space that take pictures of distant galaxies. (The Hubble - is that still working?) Can we see individual planets and stars in these pictures of far away galaxies and can we tell how those galaxies work by looking at these pictures?

2. According to the scientists, there are now only 8 major planets in our galaxy, yet there are several dwarf planets of which Pluto is now one. a.) Should these dwarf planets be included in out planetary studies? (I believe yes) b.) Do all the planets ever line up completely, as in a straight line? (if yes, then I'm sure it's very rare, right, how rare?)

3. Does anyone know when the next solar eclipse is going to be and from where will you be able to see it?

Thank you all in advance for taking the time to answer these for us!

if absence of light is darkness, that means absence of darkness is light, right? if we accept this then we accept both darkness and light exsist. But doesnt that also mean neither of these things exsist? But if neither of these thing exsist, then it means both these things exsist as well. So how can something both exist and non-exist?
