I saw a program,where they thought maybe they could move the earth,somehow,using technology,or,directing an astroid to get the earth out of the path of the sun and away from the sun,to not get fried some millions of years from now from the sun.The problem might be it would be too cold,if not moved right...What do you think?

Think of the weight of our planet, then take for example 500 tons of wood, if you burn the wood it doesn't weigh 500 tons anymore.

Also, when water evaporates it weighs less. There are also things that work the other way round, they weigh nothing until you add something to them then they are heavier.

So, heavier or lighter than 2000 years ago?
