Well, it’s not entirely true. However, there are some interesting thoughts on how to achieve it if someone has the enourmous resources and dedication it would take to unlock the secret. It’s not so much about if it is possible, said by scientists, but how long it will take to go through all the trial and errors needed to find the right combination of substances and technology.
Even though it might sound and look like pure science fiction it highly plausable that someone in the near future (if not alread) will come up with some way of cheating the gravity that is pulling us down here on earth. All is depending on how much we are ready to research it. But then again, didn’t Michael Jackson already unlock the secret of anti-gravity? LOL
