The first quote is from Jenny Randles, “Breaking the Time Barrier”

Talking of work by J Richard Gott’s team, she says: “The effect they were looking for is quite real and is known as gravitational lensing because the gravity well of such a massive object acts like a lens to focus light lays down split paths converging on the Earth.” They were dealing with pulses of light, one of which arrived a year before the other. She says: “That first light ray traveled backwards in time by approximately a year”.

There never was nothing.
