Rich aliens from strings

Totday, the India Daily Technology Team has informed the large Asian country that

  • The superstring theory in contemporary physics proves the existence of parallel universe with many higher dimensions where advanced alien civilizations prosper.

Actually, this sentence is the title.

Rich aliens seem to be one of the first practical application of string theory; they may live in a new kind of landscape. ;-) Their existence has also been shown by "rich spectroscopy at the Large Hadron Collider", our Indian colleagues argue and demonstrate it by a photograph of a fully operational collider. After the article in India Daily, The Reference Frame is the second source that informs you about the great news - and moreover tells you that you should not accept the news uncritically. ;-)

You should not think that India is the only place where such encouraging news occur. Yesterday, Canada was told that the work of Donald Coxeter from Toronto found applications in the Nobel-prize-winning carbon 60 molecule and string theory. A nice combination.

Also yesterday, another article about the liquid behavior of the "matter produced by Big Bang" appeared and the liquid behavior of the quark-gluon plasma may be "explained by some versions of string theory". Details are not specified.

Here is further reference Lubos for the perfect fluid you refer too.

Since Maldacena's conjecture does not apply to QCD, however, the viscosity of the real quark-gluon plasma cannot be computed via string theory. This makes the RHIC announcement that the viscosity of its plasma is comparable to the values one finds from string-theory calculations even more surprising. If this is true, the quark-gluon plasma created at RHIC could be the most perfect fluid in nature. This in itself is an interesting fact, but it could also indicate that string theory has some relation to real QCD. However, we first need more quantitative evidence from RHIC, such as an upper bound on the viscosity.

Imagine a "supersymmetrical idea" as a natural process. Who would have known?:)

Unrelated but interesting nevertheless.

Lubos remember right before July 13 the original schedule for Shuttle Discovery launch? I said it's troubled by the bad number 13. And indeed it was troubled.

But more trouble lies ahead since NASA re-scheduled it for the July 26th launch. That's double the 13. More bad luck. They could have shifted to a better day.

Now, they planned to bring the Shuttle back exactly on the 13th day of the mission. That's really a bad return schedule.

As we see a huge chunk falls off during launch, and NASA is so nervous that there's a launch feeze now. I can't believe they still allow debris to fall. Maybe just bad luck?

It's superstition, admittedly. Don't take it seriously. Although you never know. The first launch of Columbia in 1981, a couple hundred tiles falled off and it was OK. The last mission, one small hole and it's doomed. Must be bad luck.
