6 stunning experiments that science can’t explain
We can explain many complex things that had seemed just a fantasy, for example, the landing on the moon, the Large hadron Collider or cancer with the help of nanobots. This is all very strange and makes us look to the future with optimism. If there is something complicated, brainy guys from the Academy of Sciences will be able to explain it. But if we tell you that not every experiment is exposed to a clear explanation from the scientific community?
1. The placebo effect
It is now known that placebos actually creates change in the brain. Currently most of us understand what was going on. You go to the doctor, complain about pain in the hands, feet, head and belly, and he gives you medicine. Are you happy to go home, take the wheel and start to feel better. Then you know that the pills were dummies. What a jerk this doctor, isn’t it? Threw money out of you.
But it’s not. The doctor is somehow just fine. Researchers have long been studying the placebo effect by measuring brain activity of the patient. They were able to learn that the brain is very interesting responds to drugs that do nothing. It’s a bit like when a freshman thinks that he is drunk after drinking non-alcoholic beer.
2. Cosmic sounds
Every child knows that the space may not be sound. But in 2009 NASA scientists discovered radio waves emitted by the early stars. It was expected that noise will be negligible. But aRCADE (a device that recorded the radio waves) was able to capture such signals, which shocked scientists into a stupor. They expected to hear Elton John and received a full concert of Metallica.
Astronomers called the recordings a «space roar.» And although there are plenty of theories that describe the origin of the sound, while there is no specific evidence to support at least one of them. But we now know that in space there are massive radio signal.
3. Mpemba Effect
In other words, the paradox, which States that hot water (under certain conditions) can freeze faster than cold, although it must be temperature of the cold water in process of freezing.
Broke another brain? It is strange that this effect was discovered by the student from Tanzania, after whom it is named. Everything else was not yet any clear explanation for this paradox. Although the options certainly, there.
4. Quantum entanglement
Absolutely the craziest thing that proves the possibility of travel at faster speeds than the speed of light.
Here’s how it works: one particle splits into two. They have become interrelated, that is, regardless of how far they are from each other, are, if something happens to one part, the other one will react the same way. This happens at the same moment that, in fact, is a speed faster than the speed of light.
We have no idea how science will be able to apply such knowledge in the future. But we very much hope that Matthew McConaughey will not have to knock out the books your daughter to correct the mistakes of scientists.
5. Time is probably an illusion
Remember, «Interstellar»? There are people on the planet aged much faster than guys in space. All this is due to the fact that Einstein called variability time. According to the quantum model of the Universe, time does not exist at all. We created it to make your life easier.
Some researchers say that such a theory could explain many strange things we see in the Universe. If the observer was sitting outside, he would see that nothing really it does not change.
6. We could really change the past
According to quantum physics, very small things like atoms, which can exist either as waves or as particles. When we see them, we see one thing, however, before change, they are in a state of waves and particles simultaneously. It’s easy to remember, if we recall the analogy with schrödinger’s cat, probably the most famous thought experiment involving a dead feline.
Several experiments have shown that all that is true. The researchers isolated a single atom of helium and was sent on his way through the lasers to learn, he will lead itself as a particle or as a wave. In the end, it turned out that the atom changes its state depending on, have there been any intervention.
In other words, when the researchers significantly changed the event by introducing a second laser, when the atom has traveled through the first, changed the past. The atom behaved as a particle, although it was a wave.
