This just goes to show how much we do not know about our universe and how things really behave and move about over the years even with the advancement of the human mind and technology. Prepare for a long read because recently, scientists have been busy debunking and questioning nature's fundamental laws and they have found discreprancies that will show that the value of certain fundamental parameters, such as the speed of light or the invisible glue that holds nuclei together, may have been different in the past. So constants, seems to not be real constants.

The said differences are small, a few ppms, but even the smallest of changes would mean that the laws of physics would have to be revised--if not completely rewritten. Plus aside from the three spatial dimensions that we have grown accustomed to (length, width, and height), it seems that we might need to make room for six more spatial dimensions.

The evidence for varying constants that scientists rely on comes primarily from quasar studies. A quasar is an astronomical source of electromagnetic energy, including light, that dwarfs the energy output of the brightest stars. This one is bright and usually powered by black holes. It may readily release energy in levels equal to the output of hundreds of average galaxies combined.

Astronomer Michael Murphy heads the team that has been studying the spectra of this ancient light to determine if the early universe was different than now. Specifically, they look at absorption lines, which are due to gas clouds between us and the quasars. These lines are like fingerprints and DNA, it reveals what's in the clouds. All seems well until in 1999, the team found out that these fingerprints and DNA change in time.

How? By using the Keck Observatory in Hawaii, they detected a frequency difference between billion-year-old quasar lines and the corresponding lines measured on Earth. Also they  recently performed careful lab experiments to confirm that there is indeed a shift in the quasar spectra, since some of those Earth-bound lines are not well characterized.

So, what does this mean? Because of the difference between quasars of today and those of billion years ago, this was interpreted as indicating that light was faster in the past, or that the electron had a weaker charge. Thus grilling the Fundamental Law of the Speed of Light and that electrons had a weaker charge.

Another finding from the team of Patrick Petitjean in the Astrophysical Institute of Paris revealed that a change in the proton to electron mass ratio from molecular absorption lines in quasar spectra. Which coincides with the observed electrron charge change in the Murphy study.

And talk about rewriting the Laws of Physics. If this is proven to be accurate and true, this would be a deviance in Albert Einstein's Theories-- the Equivalence Theory which basically says that  any experiment testing nuclear or electromagnetic forces should give the same result no matter where or when it is performed; and the Gravitational Theory or general relativity.
