Cheesy title, I know… (First off, I added another paragraph to my previous entry because I somewhat shorted my explanation of Einstein’s Theory of Relativity. Hopefully the Hafele-Keating experiment will answer any questions about time and the speed of light. Please let me know if you need even more clarification)
In recent news, a particle accelerator (Relativistic Heavy Ion Collider), smaller than the LHC, at the National Energy Laboratory of Brookhaven, achieved a temperature of four trillion degrees centigrade (250,000 times higher than the center of the sun). This particle accelerator has a circumference of 2.4 miles, while the LHC has a 16.8 mile circumference. [Source: Scienceray.com]
Anyways, back to the LHC. The question at hand is seriously whether or not the Large Hadron Collider (LHC) is worth the possible detriments and world-ending consequences for the possible HOPE to find out how the world began. It’s ironic almost, in the conquest to find how/what created the Earth, Scientists might put an end to it. As stated in past blog entries, there are many people, such as Wagner, who are convinced and supposedly have “evidence” that the LHC will create black holes and have other drastic consequences on the Earth which may not appear or affect the planet for many years.
Perhaps, I should examine and explain what exactly a black hole is, how one forms, and why we should be so afraid of one forming here on Earth. The general consensus seems to be that a black hole is the equivalent of a bottomless pit in space. Not true. A black hole is actually space that has been warped by a massive star (at least 6x the size of our sun) which has died. The star once it has run out of fuel, will implode and it’s own gravity will push it together until it’s a tiny speck of an object with such an immense mass, that it warps the space around it. Imagine the dead star being a 50 lb weight, and space being a mattress that the weight (star) is on. The weight will depress the mattress (warping it) and leave a ring of depression as well, which pull other things into the dark center, hence the name ‘black hole.’ Contrary to popular belief, one cannot go through a black hole and come out into a parallel universe because at the very bottom of a black hole, is the mass of the dead star. So, for a black hole to appear on Earth and be able to sustain itself, a particle accelerator would have to be the size of our solar system to create such an expansive star to die. Here is a video of the infamous Carl Sagan on the topic of black holes… watch from 1:45-4:00. (This video was part of a segment made in 1980, so there are a few discrepancies between what Sagan says, and what scientists believe now)
According to predictions, CERN scientists of the LHC state that there are chances that a “baby black hole,” smaller than an atom is possible to be created during experiments, yet it would “radiate itself away in less than 0.00000000000000000000000001 seconds” because black holes are extremely radioactive. The laws of physics state that a lab created black hole just would not be stable, although calculations have stated that a “baby black hole” could be created every second.
So why is there still hubbub and lawsuits about the LHC? In short, the predictions and calculations could always be incorrect since the LHC is still experimental, meaning physicists are still not sure what the machine is capable of.
