Kitty could not have digested glass milk. Worse, if it had contained bacteria with the opposite hand, its immune system and its antibiotics would have to fight. A group of eminent scientists recently Warning against the synthesis of mirror image life forms For this reason – if all had to escape from the laboratory, they cover the mechanisms for the defense of regular life forms.

Continuing in the burrow of the rabbit, we see traces of chirality to the elementary particles.
Pastor’s work on the molecules was put back on a previous discovery by Augustin-Jean Fresnel, which in 1822 realized that different prisms of quartz cound sent the electric field of Light to one of the two directions-in the acute or counter-reception. If each particle of light could leave a smoke path in its wake, a smoke screw on the right would emerge from a prism and a left screw from another.
Nowadays, physicists consider chirality in the fundamental property of all elementary particles, just like the load or the mass. The particles that have no mass always move at the speed of light, and they all wear an intrinsic angular moment as if they were running like a high. If the particles fly in the direction of your thumb, their rotation follows the direction that your fingers curls up – on your right hand or your left.
The situation is a little more complicated for massive particles, such as electrons and quarks. Because a massive particles moves more slowly, a rapid observer could exceed it and effectively reverse its movement management, thus reversing its apprentice restraint. For this reason, when they describe the chirality of massive particles, physicists often refer to the mathematical description of the quantum properties of the particle. When you turn into particles, its quantum wave function moves to the left or the right depending on its chirality.
Almost all elementary particles have a twin through the glass. An electron with a negative loaded left is reflected by the anti-postron, a negative loaded right-handed particle.
In the glass world, Alice finds that all logic has turned her head: people run to stay in place, and they celebrate the “old” every day when they were not born. Likewise, our universe differs from its mirror image. The weak strength – the responsible force of radioactive decay – is only felt by the left -wing particles. This means that certain particles will decompose in the normal world while their counterparts in the mirror would not.
In addition, there is a particles that do not seem to appear in the mirror at all. Neutrino has never been observed only in its left form. Particulates physicists study when right -handed neutrinos exist or if the mirror images of neutrinos are simply identical, which Couun helps why the universe contains Something rather than nothing.
We can learn a lot about our own world by looking through the glass. Just be careful not to drink the milk.
