Most people would agree that present effects can be affected by past events. They would also agree that future events can also be affected by present events. However, many people would have a hard time understanding how the past could be affected by future events.
Simple physics is common sense to the average person. For example, time moves forward not backwards. However, there is a new study published in a Journal called Nature Physics that has shown that time may indeed move backwards. They have also found that things may be able to exist in multiple states.
The conclusions of these experiments may sound strange, but they come from two different experiments. One of the experiments has been around for a few years while the other one was performed recently. In the past, scientists performed a double slit experiment. They found that when the light was shone through a screen that had two narrow slots in it, the photon particles acted erratically. However, the photons acted like particles and casted a direct glow on the walls that were behind the slits.
Another group of scientists in Australia performed a similar experiment using helium. They found that a future measurement seemed to affect the atom’s past.
