Can the Laws of Physics Vary Throughout the Universe? Maybe, According to this Latest Research

Scientists in Australia are claiming that the laws of physics might be like local by laws which vary from one location to the next and that if this is true then Einstein’s relativity may also be wrong, the universe might be infinite, as I personally have ...

A Bound On Neutrino Speeds From Nomad

The Arxiv today features a quick-and-dirty study of the occurrence of electron-positron pair signal in the NOMAD detector, which obtains very strong bounds on the superluminal behaviour of energetic muon neutrinos like the ones whose speed has been recentl ...

Quantum Cloning?

Chinese researchers have created a hypothesis for a quantum cloning machine able to produce several copies of the state of a particle at atomic or sub-atomic scale, or quantum state, which if produced could have implications for quantum information proces ...

As Is Well Known About Lissajous Curves And Ellipses

This is a continuation of " As is well known about elliptic trajectories " where I have put it as a sort of homework to find out which force fields support elliptic trajectories. The "problem" has been solved in a response to my first p ...

Faster Than Light Neutrinos And Relativity II- A Million Dollar Bet

My recent article   on the relationship between Einstein's Theory of Relativity and superluminal neutrinos has triggered a series of comments. Some of them were reasonable, some others not. Among the reasonable doubts on this topic, there is a possibl ...

Free Quarks? Don't Be Fooled!

These days I am preparing a three-hour course of statistics for particle physicists which I will give at a winter school in a couple of months. This stimulating task forces me to find nice and simple examples of good and bad applications of basic statistic ...

The Irony of Looking for Neutrinos on Earth

Neutrinos were first postulated in 1930 by Wolfgang Pauli, who won the 1945 Nobel Prize in Physics. “I have done something very bad today by proposing a particle that cannot be detected,” Pauli wrote in his journal. “It is something no theorist should ever ...

Blog and peer reviewing- a little confusion

I would like to signal an interesting article I have found on the web: Brian Cox is wrong: blogging your research is not a recipe for disaster- by Sarah Kendrew I tend to agree with Sarah, but I also think some confusion might arise in comparing blogs with ...

Can't Buy a Gauge Symmetry

Gauge symmetry is a clear, direct idea in EM, as I will detail. This property is essential, [correction: due to redundancy found in the 4-potential description of light and not any issue of the speed of travel for the wave]. Any proposal for gravity must a ...

ELI Super Laser To Tear Space Time Apart So Ghost Particles Can Enter From Other Dimensions?

UHFF stands for Ultra-High Field Facility. The project is at times confused with the Extreme Light Infrastructure (ELI), which includes three other experiments apart from UHFF. The total bill is $1.6 billion Euros (as of now). ELI Hungary – one of four lo ...
