I’m sure someone could establish a rule for this. What is this? Well, it’s our capacity to dream things up which, eventually, become reality. Old Leonardo did it with the helicopter and other things. H G Wells and other Sci-Fi writers have done it too. What starts out as pure imagination often becomes reality, although the time it takes for fantasy to become reality can often be hundreds of years. Although, having said this, I am almost under the impression that we are starting to turn dreams into reality much more quickly nowadays, aided, no doubt by the ability of computers to, in effect, accelerate time. Manual calculations which would have taken years, can now be completed in seconds. Thus speeding the rate with which we are able to transform our ideas into reality.

Stop reading, start speaking
Stop translating in your head and start speaking Italian for real with the only audio course that prompt you to speak.
I’ve always found the Star Trek teleportation a fascinating concept, but it seemed no more than pure science fiction. But now scientists are making the first few tentative steps towards making this particular fantasy reality. This almost begs the question: ‘Where do scientists get their inspiration?’. I’m sure more than a few have read quite a lot of science fiction and then started thinking.
If you can imagine something, it will one day become reality . This is something I would put money on, although I doubt I would be around to collect my winnings. Unless, that is, eternal life becomes reality, which it will. One day.
