While no one is in disagreement about the fact that our present decisions affect the future, not everyone is convinced of it vice versa. However, there are a group of physicists that beg to differ, and what they are proposing could change everything.
According to a study published in Nature Physics, time may, in fact, move backward, things may exist in multiple states, and whether a tree falls in the woods not only may depend on whether anyone ultimately saw it, but also on whether something somehow knew it would be seen.
“It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it,” said Associate Professor Andrew Truscott from the ANU Research School of Physics and Engineering.
Basically, just as in Alice in Wonderland, time can move forwards and time can move backward. Pretty trippy, huh? And these physicists aren’t the only ones in agreement.
“The laws governing clockwork going in reverse are the same as those of clockwork going the usual way—the variable merely becomes -t,” writes physiologist and biophysicist Werner R. Loewenstein in Physics in Mind.
Now to push things even further, in another study, it was suggested that ordinary people can be changed by events that have not happened yet. The study was conducted by Daryl Bem and was published in the Journal of Personality and Social Psychology.
This study was composed of nine different experiments. In one of those, 100 students were asked to guess which curtain on a computer screen hid a picture, some of which were erotic. After 100 trials, students that were shown the erotic images guessed better 53% of the time, which was better than just guessing at random.
“The remarkable finding [we made] is that their physiological responses are observed to occur about two to three seconds prior to the appearance of the picture, even before the computer has decided whether to present a non-arousing or an arousing picture,” Bem told the Cornell Daily Sun.
As it stands, we can’t go backward in time. Or technically forwards, unless you are a scientist, but that is a whole other quantum topic. In any case, the evidence proposed in the above studies is quite fascinating and could prove to provide much knowledge for the world of physics.
