We live in time when new technologies and inventions appear almost every day. Our grandparents and even parents could not imagine that these changes would happen in reality, but not in fantastic novels. We cannot realize our world without many of them (just think about living without Internet). Today we can dream of such unreal things as flights to other planets, human and animal cloning, growing organs of our bodies, telepathy, teleportation, etc. and it is not fantasy, as everything we need is time and improving existing technologies.
If I had a chance, I would invent a time machine. The trilogy “Back to the future” was the beginning of this idea. But my time machine should have a shape of a big balloon or a sphere, inside which you could stand and travel to the past or to the future. Being inside it you could see, watch, hear everything and everybody, because the sides of the machine are crystal and clear for you, but at the same time the sphere with you inside must be invisible for the environment and you can influence on nothing.
