Time Machine Possible in New Particle Accelerator

In recent years, time traveling has been not only a scenario in science fictions and Hollywood blockbusters, but also a scientific possibility due to the rapid developments of quantum theory. Tidbits on the possibility of achieving time traveling has sprouted up in news in the past couple of weeks.

The soon to be available Large Hadron Collider (LHC, pictured above) of CERN utilizes several superconducting magnets (kept at just 1.9 K) to guide charged particles to a desired projectile. Scheduled to be in operation by May of this year, it is the largest and highest energy particle accelerator in the world.[1] Using the LHC, a special run is scheduled for April 2008 in attempt to recreate the Big Bang.

By colliding charged particles at high velocity, researchers hope to reproduce the first billionth second after the Big Bang. By successfully doing so, this exercise would further validate the theory–some claim as the origin of life–since the Nobel win of Professor George Smoot in 2007.

However, the public hype of the launch of LHC isn’t all for the recreation of the mysterious Big Bang. Much of its attention is the possibility of creating a time machine as a side product of this exercise. As mathematicians Irina Aref’eva and Igor Volovich of Moscow’s Steklov Mathematical Institute pointed out, Einstein’s theory of general relativity suggests that particle collisions at such high energy level would distort the space-time fabric surrounding it. This distortion can create a wormhole, or “time tunnel,” allowing time traveling.[2] A related interview with Irina Aref’eva is available on YouTube.

Such claim sounds little more than a scene out of some scifi movie; and many in the scientific community agrees. Most remains skeptical of the production and application of the man-made wormhole. Surely, arguments like the lack of “time travelers” from the future still echo every time machine idea is brought up. Since what will happen inside the particle accelerator is still largely unknown, its secondary consequences also remain unpredictable.

Explosion: Grad student looses both hands, face burned

Sad news coming out of Warsaw today. A 27-year old graduate student at Wojskowa Akademia Techniczna (Military University of Technology) suffered severe injuries while performing experiments towards his thesis. He lost both hands and received severe burns on his face. The explosion did not cause a fire. Apparently, his research was on explosive materials. Link to article: here (Sorry, Polish only)

If I had to guess, I would point my finger at a shock sensitive material (peroxides?). Hopefully, the mainstream press will pick-up and follow-through with the story so we can learn from this incident.

Note 1: Thanks to Borek, the ChemBuddy guy, for the tip.

IG Nobel Prizes

So after the Physics Nobel Prize Post, I felt it would be necessary to point these out as well. For those of you who don’t know what the IG Nobel Prizes are…well, I think you’ll figure it out.

Oh, one last thing. These are all awarded by The Annals of Improbable Research, which is an institution like (heh, sort-of) The Royal Swedish Academy of Sciences which awards the Chemistry and Physics Nobels, or the The Norwegian Nobel Institute which awards the Peace Nobel.

Here we go:

If that crap can get patented…Mitch, I think we need to revist that patent.

So take off your hats and raise your glasses to these brave and ignobel scientists, wasting our hard won funding, and pushing the very edge of our understanding of useless crap. Cheers.

Caffeine in Soda

This was originally covered by Bethany Halford in C&EN. But there is a paper in The Journal of Food Science (J. Food Sci. 2007, 72, C337) that lists caffeine content in all the major/minor soda manufacturers. A table of their data is shown below for your viewing pleasure. Go Vault Zero!

Article DOI: 10.1111/j.1750-3841.2007.00414.x
