#### Matrix Elements of Lorentzian Hamiltonian Constraint in LQG by Alesci,Liegener and Zipfel

This week I have been studying a number of papers about the Hamiltonian constraint operator in Loop Quantum Gravity. I’ll be reviewing these papers over the next few posts. 2,080 more words

#### QUOTE (Albert Einstein) - April 2

“The human mind is not capable of grasping the Universe. We are like a little child entering a huge library. The walls are covered to the ceilings with books in many different tongues. 116 more words

#### Homogeneous cosmological model from a discrete matter distribution

How does a homogeneous FLRW metric arise from a cosmological model with black holes as the only source of gravitational field?

In astrophysical applications of general relativity we often need to apply the Einstein’s field equations to situations where the matter distribution, and consequently also the metric tensor, has a complicated form with relatively smooth large scale behavior and a complicated structure on smaller scales. 972 more words

#### I've Been Wondering.

I have, for some reason, been pondering the size and breadth of the universe lately. By my thinking, that seems an odd proposition. I grew up with the word universe meaning essentially everything. 611 more words

#### Physicists Discover Evidence of Early Gravitational Waves

Scientists working at Harvard University’s BICEP2 project at the South Pole announced this week that they have detected evidence of gravitational waves shortly after the Big Bang. 213 more words
