There Be Dragons on the Dark Matter Issue?
I have been intrigued by the comparison of the latest reporting by Bee of Backreaction at a workshop at Perimeter Institute about the Laws of Nature: Their Nature and Knowability. Bee writes, “Yesterday, we had a talk by Marcelo Gleiser titled “What can we know of the world?”.” I look at this from a historical…

SuperCDMS An Improvement on Detection
So far no WIMP interaction has been observed, so the sensitivity needs to be improved further. This will be achieved by increasing the total detector mass (and with this the probability that a WIMP interacts in the detector) and at the same time reducing the background and improving the discrimination power. This effort started in…

Sounding Off on the Dark Matter Issue
Fermilab If dark matter can pull gravitationally, it has mass So here is an article of 2006 with some interesting information. Now these experimental procedures are always interesting to me because of the type of detectors that were dreamt up in which to measure some aspect of the reality supposed, and realized, by noise in…

One Small step…….for Mankind
It should read…Humankind. Lee Smolin: “Here is a metaphor due to Eric Weinstein that I would have put in the book had I heard it before. Let us take a different twist on the landscape of theories and consider the landscape of possible ideas about post standard model or quantum gravity physics that have been…

Acrobate Within every Point of Space
Cold Spots One would have to know that “expansionist values” for the blackholes temperature, to know, that in a “gravitational collapse” heat is generated, and thusly, the geometrical propensity to certain K values would be “indicative” on a classical level? One might never know of the relation I have with Koan’s as mentioned in my…

Our Consciousness can "Contain the Future?"
I just happen to visit Cosmic Variance yesterday after not visiting for some time. The timing seemed appropriate to my questions about our histories, not only from a detailed research perspective, but from a personal one as well in terms of our memories. I do not care who is an atheist or not. Why should…

Dark Energy: Beyond Einstein Missions
Adept Charles L. Bennett “ADEPT will measure these supernovae, but its real advance lies in a new, more powerful technique. Patterns in temperature of the very young universe provide a ‘standard ruler’ that is imprinted on the pattern of galaxies across the sky. ADEPT aims to map these through space and time,” according to Bennett…

"Lego Block" Galaxies in Early Universe
Witten: One thing I can tell you, though, is that most string theorist’s suspect that spacetime is a emergent Phenomena in the language of condensed matter physics. n this image of the Hubble Ultra Deep Field, several objects are identified as the faintest, most compact galaxies ever observed in the distant universe. They are so…

Dark Matter Issue
We’re faced with the same choices today, with galaxies and clusters playing the role of the Solar System. Except that the question has basically been answered, by observations such as the Bullet Cluster. If you modify gravity, it’s fairly straightforward (although harder than you might guess, if you’re careful about it) to change the strength…

Hubble Maps the Cosmic Web of "Clumpy" Dark Matter in 3-D
Three-Dimensional Distribution of Dark Matter in the Universe This three-dimensional map offers a first look at the web-like large-scale distribution of dark matter, an invisible form of matter that accounts for most of the universe’s mass. This milestone takes astronomers from inference to direct observation of dark matter’s influence in the universe. Because of the…

Wolf-Rayet star
While I have started off with the definition of the Wolf-Rayet star, the post ends in understanding the aspects of gravity and it’s affects, as we look at what has become of these Wolf-Rayet stars in their desimination of it’s constituent properties. Similar, “in my thinking” to the expansion of our universe? Artist’s impression of…
