It’s a busy time here in Cambridge, Massachusetts, as the US’s oldest urban Science Festival opens tomorrow for its 2015 edition. It has been 100 years since Einstein wrote his equations for gravity, known as his Theory of General Relativity, and so this year a significant part of the festival involves Celebrating Einstein. The festival kicks off tomorrow with a panel discussion of Einstein and his legacy near Harvard University — and I hope some of you can go! Here are more details:
First Parish in Cambridge, 1446 Massachusetts Avenue, Harvard Square, Cambridge
Friday, April 17; 7:30pm-9:30pm
Officially kicking off the Cambridge Science Festival, four influential physicists will sit down to discuss how Einstein’s work shaped the world we live in today and where his influence will continue to push the frontiers of science in the future!
Our esteemed panelists include:
Lisa Randall | Professor of Physics, Harvard University
Priyamvada Natarajan | Professor of Astronomy & Physics, Yale University
Clifford Will | Professor of Physics, University of Florida
Peter Galison | Professor of History of Science, Harvard University
David Kaiser | Professor of the History of Science, MIT
Cost: $10 per person, $5 per student, Tickets available now at https://speakingofeinstein.eventbrite.com

How long is it going to be before mainstream realizes ’empty’ space has mass?
How long before mainstream physics realizes spacetime has mass?
Spacetime has mass = dark matter
Matter curves spacetime
Matter displaces dark matter
Curved spacetime = Displaced dark matter
‘Empty’ space has mass. Spacetime has mass.
The Milky Way moves through and curves spacetime.
The Milky Way moves through and displaces the dark matter.
The Milky Way’s halo is the state of displacement of the dark matter.
The Milky Way’s halo *is* curved spacetime.
I’m not sure about ‘mass’ as such but mainstream physics accepts that space has energy, which is just another form of mass.
Curious. But then shouldn’t any type of matter moving likewise displace DM and thus get a ‘dark matter halo’? Why does ordinary matter appear to work fine by itself, even whole moving planets but not at the galactic scale?
“another form of mass” — Not on this website, Kudzu. Be very cautious — your explanations are cavalier, here, and working against my efforts. Please try not to confuse my readers by contradicting the conventions adopted on this website. http://profmattstrassler.com/articles-and-posts/particle-physics-basics/mass-energy-matter-etc/more-on-mass/the-two-definitions-of-mass-and-why-i-use-only-one/ http://profmattstrassler.com/2012/10/15/why-the-higgs-and-gravity-are-unrelated/
Thank you for the articles Dr.
