Saadaanko säieteorialle havaintotukea?

En nyt ehdi oikein mitään taustatietoja kirjoittaa säieteorioista, mutta niihin voi tutustua vaikka täällä: http://en.wikipedia.org/wiki/String_theory . Tähän asti säieteoria on ollut lähinnä matemaattista spekulaatiota aineen rakenteesta, mutta nyt tutkijat ovat mahdollisesti keksineet tavan saada sille havaintotukea.

"Yet inspired by Galileo Galilei and Isaac Newton, Towson University scientists say that precise measurements of the positions of solar-system bodies could reveal very slight discrepancies in what is predicted by the theory of general relativity and the equivalence principle, or establish new upper limits for measuring the effects of string theory."

"To date, there is no evidence for any of these effects. Indeed, the standard astronomical ephemeris assumes the validity of Kepler's Third Law in deriving such fundamental quantities as the length of the Astronomical Unit. But all observations in science involve some degree of experimental uncertainty. The approach of Overduin's team is to use these experimental uncertainties themselves to obtain upper limits on possible violations of the equivalence principle by the planets, moons and Trojan asteroids in the solar system."

"The limits obtained in this way are not as sensitive as those from dedicated torsion-balance or laser-ranging tests," said Mitcham. "But they are uniquely valuable as potential tests of string theory nonetheless because they cover a much wider range of test-body materials."

En ota itse vielä mitään kantaa tuohon. Aika näyttää syntyykö tästä mitään todellisia läpimurtoja uudenlaiselle fysiikalle.
