An odd space experiment has confirmed that, as quantum mechanics says, reality is what you choose it to be. Physicists have long known that a quantum of light, or photon, will behave like a particle or a wave depending on how they measure it. Now, by bouncing photons off satellites, a team has confirmed that an observer can make that decision even after a photon has made its way almost completely through the experiment—seemingly well past the point at which it would become either a wave or a particle. Such delayed-choice experiments might someday probe the fuzzy frontier between quantum theory and relativity, researchers say.

Other researchers have demonstrated the same counterintuitive effect in the laboratory. But the new work shows that a photon’s nature remains undefined even over thousands of kilometers, says Philippe Grangier, a physicist at the Institute of Optics in Palaiseau, France, who collaborated on an earlier test. “It's a very nice experiment that demonstrates their ability to do quantum physics in space.”

A photon can act like a bulletlike particle or rippling wave—but not both at once—depending on how experimenters decide to measure it. In the late 1970s, famed theoretician John Archibald Wheeler realized that experimenters could even delay the choice until the photon had made its way almost completely through an apparatus configured to emphasize one property or the other, thus proving that the photon’s behavior isn’t predetermined.

Farming is the main activity in Palampur, whereas several other activities such as small scale manufacturing, dairy, transport, etc. are carried out on a limited scale. hope
