You have to travel half a distance to reach the full distance, therefore, how is it possible to reach the full distance? eg, to reach 1 mile you have to travel half, 1/2 mile, to reach the remaining hale mile you have to travel 1/4 mile, to reach 1/4 1/8 mile and so on?

The earth rotates anticlockwise. Do all known planets (and suns?) rotate anticlockwise?

If scientists know how the universe is made then what will happen from that – what kind of benefit would they get from it?

We all have a broad range of emotions. Am I correct in believing that each emotion has an evolutionary significance? If so is each of our emotions controlled by chemicals in the brain?
