Physics constants not so constant. Unless you assume so...
Australian astronomers have combined all observations of supernovae ever made to determine that the strength of gravity has remained unchanged over the last nine billion years. (1) But is this really the case? How solid is such a conclusion? Digging a little deeper makes things more clear... The original paper can be found here. The…

Dark matter. Obvious dogmatism.
Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has so far eluded direct observation. At a recent UCLA symposium attended by 190 scientists from around the world, physicists presented several analyses that…

Science, scientific method, knowing...
The closest and brightest supernova in decades, SN 2014, brightens faster than expected for Type Ia supernovae, the exploding stars used to measure cosmic distances, according to astronomers. Another recent supernova also brightened faster than expected, suggesting that there is unsuspected new physics going on inside these exploding stars. (1) We expect things to happen.…

Roads...
A strange ribbon of energy and particles at the edge of the solar system first spotted by a NASA spacecraft appears to serve as a sort of "roadmap in the sky" for the interstellar magnetic field, scientists say. By comparing ground-based studies and in-space observations of solar system's mysterious energy ribbon, which was first discovered…

Stardust...
Water was found in stardust. (1) Life is inherent to all universe? We try to find life but it seems that it is everywhere. We thought we were special but it seems we are not? Or could it be that the whole universe is important? Why should ANYTHING be UNIMPORTANT anyway? Everything IS. What "is…
