WHAT would you do if you were invisible(隐形的)?To many people, this is a fun question.
Do you think this can be true? With recent talks of making invisibility a reality, this fun question could actually become a real problem for people and their governments to consider.
It has recently been reported that researchers in the United States and England are confident that they understand, in theory(理论), how to create an invisibility cloak(斗篷), similar to the one that Harry Potter received from his father. They have already begun to work on it, and are asking for help in developing the material that would be used to create this invisibility cloak.
“Is it science fiction? Well, it’s a theory and that already is not science fiction,” said Professor Sir John Pendry. “It’s possible in theory to do all these Harry Potter things, but we should face the challenge, that is our engineering ability.
“Now, no invisibility cloak has been made yet, but the first testing of invisibility technology could be soon,” said Pendry. “We will have a cloak after not too long.”
Though the idea sounds great, it could be a bad thing if it is used in wars.
