Theory: Before Big Bang, Time Ran Backward in Mirror Universe

Here’s a strange theory: our universe has a mirror image where time runs backwards. If a mirror image of our universe existed before the big bang, it might simplify a lot of things in physics. Like a mountain looming over a calm lake, it seems the universe may once have had a perfect mirror image. That’s the conclusion a team of Canadian scientists reached after extrapolating the laws of the universe both before and after the Big Bang. Physicists have a pretty good idea of the structure of the universe just a couple of seconds after the Big Bang, moving … Continue reading Theory: Before Big Bang, Time Ran Backward in Mirror Universe

Claim: Cooling Without Energy Consumption

These scientists didn’t break a law of physics, but it appeared so at first. The second law of thermodynamics, one of the fundamental rules of this universe, says that heat can flow by itself only from a warmer to a colder object. Now, however, in the strangest claim I’ve found for this Sunday morning, researchers at the physics department in Zurich used a Peltier element to cool a nine-gram piece of copper from over 100°C to significantly below room temperature without an external power supply. Heat will not leave a cold object for a warmer one (to further cool the … Continue reading Claim: Cooling Without Energy Consumption

Space, the Final Illusion?

The most surprising thing I heard recently, which I believe will prove to be true, is that distance is not real, at least not in the way we think of it. Lee Smolin, a professor of physics, has an impressive article at scientificamerican.com which speculates that space and distance are a certain kind of illusion, an average of more fundamental processes. The beauty of this view is that it explains repeated observations that entangled particles influence each other instantly at a distance, faster than the speed of light, which should be, by our current model of space-time, impossible. … the … Continue reading Space, the Final Illusion?

The Largest Known Structure in the Universe

The scale of the universe is mind-boggling. Within that boggle is a strange fact: the largest “structure” we have observed in the universe is so large that it should not exist according to current science. The largest structure (so far as of March 29, 2019) is the “Her-Cr Great Wall”. Why should this sheet-like group of galaxies not exist, though? Well, the universe’s maximum light travel distance is supposed to be only 13 billion years. With the speed of light is a constant and given the known expansion rate of the universe, the Her-Cr Great Wall structure should not have … Continue reading The Largest Known Structure in the Universe

Higgs-like particle suggests end to universe

Did you konw that an expanding bubble of nothingness could make the entire earth wink out of existence in an instant? It could, according to physics, but some have calculated the odds are exceedingly low that this will ever happen. Most certainly, nothingness will not engulf the earth in our time. If that is wrong, you will never know it. This photo of supernova (explosion of a star) SNR 0509-67.5 was recently released by NASA and is a testament to how beautiful even the farthest reaches of the natural (or celestial) world can be. The pink ring is the gas … Continue reading Higgs-like particle suggests end to universe
