Science Fiction

We already know what science fiction is, are stories about imaginary things that are related to science, but breaking parameters of existing natural science and leads us to a world of imagination.What can happen if this science fiction becomes reality in a determinate moment? For example:
What happen if we are in class and one of our classmates begins to fly? This action, that we saw in a movieand think, would be great fly or met something that can fly, will scare us?
We can imagine that one day in class our professor Melvin instead open the door pass through a wall or door?
Zoology saysthat the animals can walk, see, smell and more, but we the humans, when have a pet we humanize it, we say that our pet is sad or happy; we say that my dog loves me, and my dog miss me! We dress andcomb our pet, but I imagine if one day I come from the high school and my dog, Sisi, tell me, how was your day? Or I love you! I only can think what can happen to me….
Maybe one day all the thingsthat now we see like impossible and like science fiction come to be true and part of our everyday life, because like 50 years ago the people believe impossible go to the space or to the moon! And nowthat are possible, and the scientists are thinking go to Mars. Many years ago the people do not even imagine that with a clik can have access to all history, communicate with other people, things thatnow are normal for us!
The science fiction is important on our lives; it makes possible the imagination of all kids that plays theirs wonderful and wear games, like be a super hero, or fly, or be afriend with a alien; and the science fiction make possible the advance of technology, in the past a crazy idea was fly to the moon, but now is possible, so the science fiction puts on our lives achallenge to advance on technology. This is because the science fiction are crazy ideas about what could be cool that happen in sciences, but not exist yet.
How far is that the current science fiction...
