Light That Is Not Light Interacts With Light That Is

Some of the strangest truths are found in physics. One of the rarest events humans have detected is the spontaneous turning of a photon of light into a virtual pair, an electron and a positron. Scientists working at the Large Hadron Collider beneath the French-Swiss border recently detected, after recording trillions upon trillions of events … Continue reading

Videos: The Simplest Motors

They look so simple that they should not work, yet homopolar motors do. A homopolar motor is a direct current (DC) electric motor which produces constant circular motion due to this fact: an electric current flowing through a wire that is in a magnetic field feels a force pushing it. The same force can be … Continue reading

Video: Copper’s Surprising Reaction to Strong Magnets

This video is fascinating to me, the best strange thing for today. It shows magnetic breaking using a large copper plate and a strong neodymium magnet. The slowing of momentum looks almost supernatural, like something in the Matrix. The large copper plate is not magnetic, but it slows a strong magnet’s movement due to rapidly … Continue reading

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. … Continue reading

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 … Continue reading

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, … Continue reading

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 … Continue reading

A Rock is a Clock: Physicist Uses Matter to Tell Time

What is stranger than time itself? Have you thought about what time is? Wondering about that since he was a kid growing up in Germany lead Holger Müller to come up with a fundamentally new way to measure time as assistant professor of physics at the University of California, Berkeley. To accomplish this, he used … Continue reading

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, … Continue reading
