I don't reckon the world has reached its peak in attaining knowledge.
Some scientists are saying that in the next couple of centuries, discoveries based on energy will be made, that nobody could have thought possible.
The fact that we are able to contact each other from one side of the earth to the other now, whilst in the 17th century electricity hadn't even been discovered, is amazing. If we were to bring somebody from that era to this very day, they would probably think its all workings of black magic.
I just wonder what the future will hold. Any possible imaginings?
