Hubble Finds Evidence for Dark Energy in the Young Universe
I had to go back to the article for some further reading. These snapshots, taken by NASA’s Hubble Space Telescope, reveal five supernovae, or exploding stars, and their host galaxies. The arrows in the top row of images point to the supernovae. The bottom row shows the host galaxies before or after the stars exploded.…

Cosmic ray spallation
As this NASA chart indicates, 70 percent or more of the universe consists of dark energy, about which we know next to nothing Other explanations of dark energy, called “quintessence,” originate from theoretical high-energy physics. In addition to baryons, photons, neutrinos, and cold dark matter, quintessence posits a fifth kind of matter (hence the name),…

Tunnelling in Faster then Light
Underneath this speculation of mine is the geometrical inclination of the universe in expression. If it’s “dynamical nature is revealed” what allows us to think of why this universe at this time and junction, should be flat(?) according to the time of this universe in expression? Omega=the actual density to the critical density If we…

Three Ring Circus: Dark Energy
“Observations always involve theory.”Edwin Hubble Hopefully some day, I will be accepted as a student of this universe, and it’s intrigue? Sometimes it is necessary to understand that having come to different consclusion about the geometry of this universe that underneath the complexity of these equations a schematic drawing of reality is unfolding? I think…

Lisa Randall on Xtra Dimensions
In physics, Randall-Sundrum models imagine that the real world is a higher-dimensional Universe described by warped geometry. More concretely, our Universe is a five-dimensional anti de Sitter space and the elementary particles except for the graviton are localized on a (3 + 1)-dimensional brane or branes. The models were proposed in 1999 by Lisa Randall…

Back to the Beginning of Time
While some of us who had been engaged in a little prehistory examination of earliest QGP states as glast determination of high energy photons, the question, “to Be or not to be,” how could we not ask what Professor Susskind offered up for examination under the title, “the elephant and the event horizon?” What happens…

Understanding the Tonal
Sir Isaac Newton So, you have your units, and the powers of ten? Distances shorter than 1 µm 1 micrometre (micron)Items with lengths between 1-10 µm (microns)1.55 µm — wavelength of light used in optical fibre6 µm — anthrax spore6-8 µm — diameter of a human red blood cell7 µm — diameter of the nucleus…

Central Theme is the Sun
A lot of times people do not understand the effects something can have and after we see these effects, we wonder how did we ever miss the importance of what layed underneath this process in Physics. Richard Feynman-Dancing With Neutrinos-Nova Much as we looked at the stars above, the views became much clearer with hubble…

Why do physicists want to study particles?
A few “cosmic rays” pass through our body every second of every day, regardless of where we are. They consist of particles created when high energy atomic nuclei (mainly protons) coming from outer space collide with the atoms at the top of the earth’s atmosphere. Such particles are not just electrons, protons and neutrons, but…
