This is disappointing:
“University of Chicago astronomers found no evidence for extra spatial dimensions to the universe based on the gravitational wave data. Their research, published in the Journal of Cosmology and Astroparticle Physics, is one of many papers in the wake of the extraordinary announcement last year that LIGO had detected a neutron star collision”

Einstein is back to stay!
Click here for today’s report from Britain’s Guardian newspaper.
I expect that sooner or later our exploration of Einstein’s Theories of Relativity will take in the work of the Large Hadron Collider in Switzerland. That has something to do with dark matter particles and how gravity is caused.
I confess its work is a little nebulous to me on my current level of understanding (!) but I’m determined that we will get there when the time is right.
But the Collider has had some rather unexpected problems to cope with lately. It may have truly great aims on a galactic scale – but it’s still vulnerable to weasels chewing through the cables! Read how the Guardian reported the incident here.
Well, there are worse ways to spend your Saturday, I suppose! Coming up soon is a link to an example site for – of all things – a fish and chip shop.
Now there’s a trailer to rival Star Wars The Force Awakens …
Just as I am starting my Relativity blog, suddenly doubt is cast on the Theory / Theories! Yesterday the Huffington Post published a super short article by George Musser entitled Why Space and Time Might Be An Illusion. It is well worth a read.
Einstein has been all over the news recently because of the anniversary of his work and because of the discovery a couple of months ago that the gravitational waves he predicted do actually exist. But in fact any scientific theory only lasts as long as it takes someone else to disprove or modify it. Whilst that’s not happened yet, there continues to exist a tension between Relativity, on the one hand, and quantum theory on the other. For reasons which this blog will hopefully lead me to discover (er.. let’s hope) physicists dispute that both theories can live the same world, or universe.
So it makes no sense for people to say that they are “supporters” of one theory over another. You have to go with an open mind to wherever the evidence takes you. Or in my case, with an empty mind …
