Particle Physics

Can a black-hole be created on earth by LHC?

This post belongs to the eschaton theme. Which means a small and swift blog post just to do justice to something that can’t be made comprehensively large by any reason, at the moment. 

Read the linked news article which giving excerpts from a book by the famed Martin Rees which I haven’t read, nonetheless which sound very tenuous on the scientific merit its purported to be based on, claims that particle physics experiments can create black-hole catastrophes on earth in the very unfortunate event that something goes wrong.

Here is my initial reaction to the article. 

“apocalypse mongering”

Earth’s Schwarzschild radius is less than 1 cm. What that means is earth needs to be compressed into a sphere of that radius with its current given mass, for it to turn into a black-hole.

There is nothing there.

According to classical mechanics — from 400 year old knowledge of physics, space and time have been considered to be separate entities but not fundamental. Space and time were not considered fundamental quantities as these parameters did not have the mandate to change physical laws of nature. They were merely the tools of the mind or the more aptly the conscious mind. They help us visualize but not dictate what ought to happen.

My PhD Thesis, Preliminary Exam !

But my own PhD thesis is a kind of different tale altogether. For my work there is no CP Violation.

In CP Violation two leptons (electrons and positrons are leptons) are imparted quite good amount of energy and made to collide against each other. Thus just like in CERN lab, there is a much smaller tunnel at the Tsukuba facility, called an accelerator-detector facility. In this facility an electron and positron pairs are given enough energy and made to circle in opposite direction.

When they collide, they are made to do so, right inside the detector. They produce pairs of B-mesons. The B-meson one and two, they are almost at rest when they are produced, in the lab frame of reference. But the matter of fact is the B-mesons are produced from what are called Upsilon (4S) mesons.

These Upsilons are called resonances, and they are highly unstable (all resonances are short lived elementary particles). So they turn into B-mesons as soon as they are created.

Why India can go to Mars and not the atom?

Whats the electron’s electricity bill? Our democracy has made it easier that if every person pays a little particle physics is really not that expensive, even less expensive than Diwali, Diwali comes every year. A lab for example would stay for 3 decades if opened.

I worked for a particle lab whose cms energy for electron’s acceleration was roughly 10.5 GeV. Thats basically the energy if each person in India buys a battery of 1 Volt and gifts it to the lab as each battery would accelerate the electron a level of 1 eV and roughly the population of India would be needed to accelerate the electron to 10.5 GeV, assuming each one’s battery accelerates to 1 eV.

There will be other similar expenditures also, but this is like the electric bill for the electron. Says why particle physics is not really as expensive for the country as are eg riot expenditures or even Diwali crackers.
