  • Are Artifacts of CMB Right Next to Me?

     Looking back seems strange to me and that if one is to take such a position then evidence must exist in this very moment? Models of Earlier Events This may seem like a stupid question to some, but for me it is really about looking at where I exist in the universe and what exists…

  • Lawrence Krauss – Debate in Stockholm, 2013

    A discussion about the definition of nothing. And the relation of philosophy and theology to science. Attendees are Lawrence M Krauss, Bengt Gustafsson, Åsa Wikforss, Stefan Gustavsson and Ulrika Engström. Moderator: Christer SturmarkLawrence Krauss – Debate in Stockholm, 2013 See: Quantum Gravity in the Cosmic Microwave Background?  Using Cosmology to Establish the Quantization of Gravity…

  • All-sky map

    All-sky map of the CMB, created from 9 years of WMAP data Comparison of CMB results from COBE, WMAP and Planck – March 21, 2013. Working out what happened in the moments after the Big Bang is difficult. Scientists can come up with theories, but in the end they are useful only if they can…

  • Holometer

    Holometer Revised This plot shows the sensitivity of various experiments to fluctuations in space and time. Horizontal axis is the log of apparatus size (or duration time the speed of light), in meters; vertical axis is the log of the rms fluctuation amplitude in the same units. The lower left corner represents the Planck length…

  • Probing the early and present Universe with Planck

    Date: 05 Jul 2010Satellite: PlanckCopyright: ESA, HFI and LFI consortia  This multi-colour all-sky image of the microwave sky has been synthesized using data spanning the full frequency range of Planck, which covers the electromagnetic spectrum from 30 to 857 GHz. The grainy structure of the CMB, with its tiny temperature fluctuations reflecting the primordial density…

  • The Cosmic Landscape

    I noticed a few blogs mentioning the landscape. Asymptotia(Clifford Johnson), The Reference Frame(Lubos Motl), and Not Even Wrong (Peter Woit’s) blog. The Cosmic Landscape:String Theory and the Illusion of Intelligent Design by Leonard Susskind After reading Susskind’s book in regards to the landscape issue, I was intrigued by the First Three Microseconds previous as it…

  • Great Pyramid was built inside out, Frenchman says

    Man ponders shadow, or shadow ponders itself? Great Pyramid of Giza was the world’s tallest building from c. 2570 BC to c. 1300 AD.† For me, this has always been somewhat of an interest of mine. I’ll tell a little bit of why this is so as well. Give you some ideas about what the…

  • The Physics of Mind

    It might be that the laws change absolutely with time; that gravity for instance varies with time and that this inverse square law has a strength which depends on how long it is since the beginning of time. In other words, it’s possible that in the future we’ll have more understanding of everything and physics…

  • The Multiverse is like a….Flower?

    Alexander Vilenkin The implications of inflation are particularly important in the context of the landscape of string theory. One of the leading researchers studying how inflationary cosmology evolves through the landscape is Alex Vilenkin, a theoretical physicist at Tufts who has been working in the field of cosmology for 25 years and is a pioneer…

  • First Stars Behind the Scene

    There are several recognized processes from the early universe that leave relic effects setting the stage for galaxy formation and evolution. We deal here with the first generarion of stars, primordial nucleosynthesis, the epoch of recombination, and the thermal history of various cosmic backgrounds. Part of understanding the time line is first knowing where the…

  • Box Counting or "Points" on the Strings Length?

    The jump from conventional field theories of point-like objects to a theory of one-dimensional objects has striking implications. The vibration spectrum of the string contains a massless spin-2 particle: the graviton. Its long wavelength interactions are described by Einstein’s theory of General Relativity. Thus General Relativity may be viewed as a prediction of string theory!…
