String theory literature tells us that ST predicts the four forces: weak, strong, EM, and gravity. What it fails to tell us is if that's all the forces it predicts. Might there be a fifth force that ST predicts, but was thrown out because there is no observable evidence in 4D space that a fifth force exits? Might that fifth force, if there is one, account for the so-called dark energy in the universe?

I think we may finally master magnetic levitation for daily transport, there is even a floating bed made with magnets already! There will be special helmets that probe different sectors of the brain and provide a correct electrical shock, therby making school no longer than ::snaps fingers:: that. What do you hope will be invented by then? Please give an explanation if possible.

What is different about the US that puts us on the same level as Turkey in responding to this question? Do Americans mistrust science more? Is there a problem with high school biology in this country? Serious answers please
