A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the atoms themselves are the ones saying so.

Physicists have not published a definition for ´time´ up to now.
Every statement about ´time´ is of poor quality — as long we don´t have a definition for ´time´.
Our earth rotates and moves around the sun. Our sun-system is part of a rotating galaxy which moved through an expanding universe.
The idea of a ´negative time´ is therefore doubtful: because then all these dynamic movements must be reversed too, when ´time´ would be negative!
