It seems that scientific experiments can only confirm or refute the assumptions of researchers. But sometimes in the course of their research they receive unexpected results that do not know how to explain all. < Website tells the story of six such experiments, of which failed to make an unambiguous conclusion.
1. Effect platsebo
We now know that the placebo actually creates a change in the brain. You say that the tablets should help, and you really feel relieved, while in fact, these pills - ordinary candy. But why does it work?
Researchers have long studied the placebo effect by measuring the activity of the patient's brain. They were able to learn that the brain responds to very interesting drugs that do nothing. But why this happens - is unknown
2.. Space zvuki
Every child knows that in the space, the sound may not be distributed. But in 2009, NASA scientists have discovered radio waves emitted by the early stars. It was expected that the "noise" will be negligible. But ARCADE (the device that captured radio waves) was able to capture signals that scientists plunged into a stupor.
Astronomers call these notes "cosmic roar." And although there is a complete theory, telling the origin of the sound, yet there is no concrete evidence to support at least one of them.
3. Effect Mpemby
In other words, the paradox, which states that the hot water (under certain conditions) may freeze faster than cold, although in this case it should pass the temperature of cold water in the freezing process.
Surprisingly, this effect is found student from Tanzania, after whom it is named. Everything else was not found yet no clear explanation for this paradox. Although the embodiments, of course, there are.
4. Quantum zaputannost
It is a crazy thing, which proves the ability to travel at higher speeds than the speed of light. Here's how it works: one particle is divided into two. They are interrelated, that is, no matter how far they are from each other, if something happens to one particle, the other will react the same way. It happens in an instant, that, in essence, is a speed faster than light. We have no idea how science can apply such knowledge in the future.
5. Time probably illyuziya
In accordance with the quantum model of the universe, there is no time at all. This is what we designed it to make your life easier. Some researchers say that such a theory could explain many strange things that we see in the universe. If an observer sitting outside it, he would have seen that nothing is actually it does not change.
6. Past amenable izmeneniyu
According to quantum physics, very small particles, such as atoms, can exist as either waves or particles. When we observe their status, we see that one thing, however, before the change, they are able to both particle and wave. It's easy to remember, if you remember the analogy of Schrödinger cat, probably the most famous thought experiment with the participation of a representative of a dead cat.
Several experiments have shown that all of this is true. Researchers have identified one atom of helium and sent on a journey through the lasers to learn, lead it as a particle or as a wave. As a result, it was found that the atom changes its state depending on whether the intervention occurred.
In other words, when the researchers changed substantially event by entering a second laser, when the atom traveling through the first, changed the past. Atoms behave like a particle, although this was a wave.
