A photo open source British physicist Lord Kelvin in 1900 argued that all the important discoveries of science have already been made. However quantum mechanics and relativity Einstein produced a real revolution, and today no physicist dares to say that our physical knowledge of the universe is nearing completion. On the contrary, each new discovery automatically gives birth to more and more questions …
How to measure the collapse of quantum wave functions?
In the realm of photons, electrons and other elementary particles quantum mechanics is law. Particles behave like waves which spread over a vast area. Every particle described by a “wave function” that speaks of its possible location, speed and other properties. Actually a particle has a range of values for all properties until its not experimentally measured. At the time of detection, its wave the function is destroyed. But, why and how to measure particles in that the reality that we perceive is crashing for their wave function? A question known as a measurement problem may seem esoteric, but our understanding of what our reality is, and does it exist at all – is also under a large a question. Why are there more substances than antimatter? Actually the main question is why something exists at all. Some scientists suggest that after The big bang matter and antimatter were symmetrical. If it was so, then the world we saw would be immediately destroyed – electrons would react with antielectrons, protons with antiprotons and so on, leaving behind only a sea of “naked” photons. The arrow of time Time moves forward because a property of the universe called “entropy” is roughly determined like the level of increasing confusion and therefore there is no ways to reverse the growth of entropy after it already happened. But the main question is: why is entropy was at a low level at the time of the birth of the universe, when a relatively small space was overflowing with a colossal energy? What is dark matter? In the Universe more than 80% of matter that does not radiate and does not absorb light. Since dark matter is not visible, its existence, as well as properties are fixed due to its gravitational effect on visible matter, radiation and a change in the structure of the universe. This dark substance penetrates the outskirts of the galaxy and consists of “weakly interacting massive particles. “What is dark energy? It is believed that dark energy is cosmological constant, an integral property of space that has negative pressure. More than space expands, the more space is created, and with him and dark energy. Based on observed expansion rate scientists know that the mass of all dark energy should be about 70% of the total content of the universe. However, scientists are still can’t find a way to look for her. Time Universe
