The Sound of Two Black Holes Colliding
Audio Credit: Caltech/MIT/LIGO Lab As the black holes spiral closer and closer in together, the frequency of the gravitational waves increases. Scientists call these sounds “chirps,” because some events that generate gravitation waves would sound like a bird’s chirp. See: The Sound of Two Black Holes Colliding This is an Audio Animation above. *** The…

The Map of B Mode Imprints
Figure 3: Left: BICEP2 apodized E-mode and B-mode maps filtered to 50 < ℓ < 120. Right: The equivalent maps for the first of the lensed-ΛCDM+noise simulations. The color scale displays the E-mode scalar and B-mode pseudoscalar patterns while the lines display the equivalent magnitude and orientation of the linear polarization. Note that excess B-mode is detected over lensing+noise…

Weber Bars Ring True?
Gravitational Radiation Gravitational waves have a polarization pattern that causes objects to expand in one direction, while contracting in the perpendicular direction. That is, they have spin two. This is because gravity waves are fluctuations in the tensorial metric of space-time. How would you map this above? WMAP image of the Cosmic Microwave Background Radiation…

Weber Bars
The following detectors participate into the IGEC. Click on a name to connect to the experiment web site. In the picture below the detectors locations on earth are represented. It happens that there is a great circle passing near each site (red line on the picture below) This allows for parallel orientation of the bars.…

Observational Gravitational-Wave Astronomy.
Figure 1: Gravitational wave strain and strain sensitivity for a 5 year observation with PTAs.The red dashed line is the approximate strain sensitivity for current PTAs (11), and the greendashed line shows the previous estimate for the stochastic signal strength that is currently instandard use for PTA analyses (13, 14). The dark blue solid line…

New Synesthete Character on Heroes
For example, in 1704 Sir Isaac Newton struggled to devise mathematical formulas to equate the vibrational frequency of sound waves with a corresponding wavelength of light. He failed to find his hoped-for translation algorithm, but the idea of correspondence took root, and the first practical application of it appears to be the clavecin oculaire, an…

Loosing Sight of Discrete Geometry
Discrete mathematics, also called finite mathematics or decision mathematics, is the study of mathematical structures that are fundamentally discrete in the sense of not supporting or requiring the notion of continuity. Objects studied in finite mathematics are largely countable sets such as integers, finite graphs, and formal languages. Discrete mathematics has become popular in recent…

Kip Thorne on Space Place Live and Cosmc Colors
The most important thing is to be motivated by your own intellectual curiosity. KIP THORNE Click here to watch Kip Thorne on Space Place Live. The “Color of Gravity to Sound” forces perspective. What can I say? It becomes an exercise into an artistic adventure. So there has to be a historical development in any…

The Ring of Truth
Savas Dimopoulos:Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across the surface. But we also hear the click of sound as they impact: that’s collision…
