Finding the Mass of a Particle

04-09-2015

Two points which contain a charge of 50 nC and -90 nC are fixed on an x-axis. The first point is located at the origin and the second point is located at x = 87cm, respectively. 93 more words

Trying to understand dark matter [CL]

http://arxiv.org/abs/1502.07375

We present some “back-of-the-envelope” calculations to try to understand cold dark matter, its searches, and extensions of the Standard Model. Some of the insights obtained from this exercise may be useful. 12 more words

Dark Energy, Inflation, CMB Anisotropy and Polarization from Quantum Metric Fluctuations [CL]

http://arxiv.org/abs/1410.1416

We propose a model of cosmological evolution of the early and late Universe which is consistent with observational data and naturally explains the origin of inflation and dark energy (DE). 277 more words

Constraining Parameters of Generalized Cosmic Chaplygin Gas in Loop Quantum Cosmology [CL]

http://arxiv.org/abs/1409.7057

We have assumed the FRW universe in loop quantum cosmology (LQC) model filled with the dark matter and the Generalized Cosmic Chaplygin gas (GCCG) type dark energy where dark matter follows the linear equation of state. 237 more words
