"Can a rifle bullet traveling faster than sound be heard before it arrives?" he asked enigmatically.
"No."
"Then a body traveling faster than light cannot be seen before it arrives! Those pictures show a region of the sky and a few stellar catastrophes that took place years ago when the light left there unless—"
"Unless what?"
"Unless the telescope made of the teleport mirror effect utilizes a type of radiation that propagates faster than light."
Rhine nodded. "If celestial bodies can travel faster than light," she said, "it stands to reason that some form of energy can travel faster than light also. After all, matter is one form of energy."
Carroll smiled quietly. "This is negative matter," he said. "And so far as I have been able to calculate, the only thing that can avoid the Einstein increase in mass with increase in energy would be some object having negative mass. But negative mass is as meaningless a term as negative energy."
"A gentleman by the name of Dirac got the Nobel Prize for postulating states of negative kinetic energy," said Rhine.
"The positron," nodded Carroll.
"Then it must make sense."
