Kitty could not have digested glass milk. Worse, if it contained bacteria with the opposite hand, its immune system and antibiotics would have been poorly suited 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 the laboratory, they could escape the mechanisms of defense of regular life forms.
Narrowing
Continuing in the burrow of the rabbit, we see traces of chirality to the elementary particles.
Pastor’s work on the molecules were based on a previous discovery by Augustin-Jean Fresnel, which in 1822 realized that different firm quartz prisms could send the Light electric field turning into one of the two directions-in the opposite direction or counter-class. 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 as a 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 also have 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 particle moves more slowly, a rapid observer could exceed it and effectively reverse its direction of movement, thus reversing its apparent reservoir. 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 a particle, its quantum wave function moves to the left or the right depending on its chirality.
Almost every elementary particle has a twin through the glass. An electron on the left negatively loaded is reflected by the anti-positron, a right-handed particle charged negatively.
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 particle that does not seem to appear in the mirror at all. Neutrino has never been observed only in its left form. Particle physicists study if the right -of -right neutrino exists or if the mirror images of neutrinos are simply identical, which could help to explain 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.
