Not Possible
1615 – Galileo Galilei – “a true physical demonstration that the sun does not circle the earth but the earth circles the sun” – Not possible before.
2015 – NASA – announced that something very large exited a black hole – Not possible before.
The only thing not possible today is to have around you people that will understand that not possible today it is possible tomorrow.
Eliminate not possible and be ready to really change something now. Believe it or not, we are using the internet to have fun. Sometimes, of course when it doesn't use us.
