To possibly destroy the Earth with a black hole, or not to possibly destroy the Earth…. that is the question?

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:]

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.

Let’s clear a few things up…

In my last blog entry, I stated that when the LHC reaches the speed of light, time will stop. What I meant is that the time around the LHC will stop, not the entire time of the planet Earth. Dr. Eric Christian says “The standard equation for “time dilation” is that the time passing on Earth will equal the time on the object * 1/sqrt(1-((v*v)/(c*c))), where v is the velocity of the object and c is the speed of light. At v=c this goes to infinity, or in other words, time would stop for an object moving at the speed of light. This is not a problem because objects can’t go at the speed of light — it would take an infinite amount of energy (and their mass would also become infinite).” This can also relate to the twin paradox, an example of relativity at work.

In short, the atoms inside the particle accelerator will be going so fast and will be so close to the speed of light, that they will age extremely slowly because the time around them will have slowed down drastically. Only the objects going near the speed of light will experience this phenomena. Time does some strange things at high speeds which The Hafele-Keating Experiment, for example, illustrates. In 1971,  J.C. Hafele and Richard E. Keating created an experiment in which they brought atomic clocks onto an airplane, which reach speeds of 600 mph or so, and placed atomic clocks on the ground as well. These men simultaneously started the clocks on the ground and the clocks on the airplane then proceeded to fly around the world twice, once going eastward and once going westward to test Einsteins theory of relativity. In conclusion, the atomic clocks on the airplane, because they were extremely fast, were actually BEHIND, or SLOWER than the atomic clocks on the ground. This proves relativity because time slowed down as the clocks went somewhat near the speed of light! Hopefully that will help one understand the magnitude of the LHC traveling up to 99.99% the speed of light!

Here is a video of Dr. Walter L Wagner discussing the potential dangers of the LHC on Earth.

Snow day

Snowed in today so maybe I should do something somewhat productive. Why not update the good ole Senior Exit Project blog?

So far, I’ve decided to do my Senior Exit Project on CERN’s gigantic particle accelerator, also known as the LHC (large hadron collider). Turns out, my brother’s friend’s roommate interned at CERN last summer. My brother also told me  he can possibly get an interview which would completely validate my project. Here’s a picture of this intern at another day of work:

Although that isn’t the LHC located under Switzerland and France, it’s one of the many experiments conducted by CERN.

CERN has planned to start up the LHC again on February 15th, 2010 after many failed previous attempts. In September of 2008 the LHC had to be shut down after a few days because of major repairs needing to be done. The following year in November, the LHC was shut down due to the upcoming winter, but scientists recorded the highest collisions ever produced by humans. On February 15th, scientists want the LHC to run at full power, meaning near (99.9%) the speed of light in the year 2011. If CERN is able to reach the speed of light, time will actually stop. As the LHC nears the speed of light, time will significantly slow down.

Many critics believe this restarting of the LHC will cause great harm to the world, even resulting in a black hole. CERN believes that such a situation is very unlikely, but will not testify that it is impossible. Walter L. Wagner and Luis Sancho have concluded the LHC could not only produce a black hole, but a “strangelet,” which would change Earth into a “shrunken dense dead lump of something called ‘strange matter.’” They also are pinning down CERN for disobeying the National Environmental Policy Act by not providing an environmental impact statement.

What does all this mean? Basically, CERN is either fighting propaganda created by the scared population, or creating the propaganda just to progress science, even at the risk of the planet. So far, no harm has been done by the LHC (aside from needing $8 billion for it’s construction/repairs), but CERN has barely scratched the surface with the massive machine and there is still expansive room for error.
