Alan Moore on Science, Imagination, Language and Spirits of Place

In an excellent interview with the Daily Grail, author Alan Moore talks about the spirits of a place, time and simultaneity, and how the ephemeral artifacts of the current times are making it harder for the next generation to be… Continue Reading →

GeekDad: Observation of Gravitational Waves from a Binary Black Hole Merger

One Hundred years after Albert Einstein predicted the existence of Gravitational Waves, the announcement that they had been discovered finally came. The two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO)  simultaneously observed a transient gravitational-wave signal last year on September 14th. From the Introduction in the Physical Review Letters paper:
"In 1916, the year after the final formulation of the field equations of general relativity, Albert Einstein predicted the existence of gravitational waves. He found that the linearized weak-field equations had wave solutions: transverse waves of spatial strain that travel at the speed of light, generated by time variations of the mass quadrupole moment of the source. Einstein understood that gravitational-wave amplitudes would be remarkably small; moreover, until the Chapel Hill conference in 1957 there was significant debate about the physical reality of gravitational waves."
 
From the Conclusion:
 
"The LIGO detectors have observed gravitational waves from the merger of two stellar-mass black holes. The detected waveform matches the predictions of general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. These observations demonstrate the existence of binary stellar-mass black hole systems. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger."

Time’s Arrow

Merciless, time watches over our abject forms, And steals lovely night with break of day. It tempts with burned images that swim in brief ecstasy and are lost, Our memory a shoddy palimpsest of battling desires and warring ideas. The… Continue Reading →

Past, Present and Future – Ghosts All

View image | gettyimages.com The concepts of Past, Present and Future are as insubstantial as ghosts. The present is an illusory horizon line between the so-called past and the so-called future. If there is no present, where do the past… Continue Reading →

Proposition (VIII)

All of the energy in the Universe is the product of oppositions – a manifestation of the tension between the ideal states of Something and Nothing. Corollary. – The total amount of energy in the universe is zero, because the… Continue Reading →

There’s no Heaven or Hell – But, Don’t Worry

Imagine standing in the most beautiful garden you’ve ever seen. The sun is shining, the grass is lush. To your left are rolling hills that become the feet of great mountains. To your right just through the foliage the gentle… Continue Reading →

Information Overload: We’ve Had it Since the Beginning of Time

How does a number such as Pi exist in the universe? It’s probably been written down to certain degrees of accuracy many times over – and stored on as many electronic devices. Some people can hold hundreds of digits of… Continue Reading →

Why is There Something Rather Than Nothing?

The raw nature of existence appears to be one of those intractable questions that is problematic for many reasons. Yet again the limitations of language and semantics are complicating the issue. The basic definition of ‘nothing’ is (depending on your… Continue Reading →
