On the Ineffable

This 18th century depiction of Yamantaka, a violent expression of the Bodhisattva Manjushri, defeats Yama, god of death, and demolishes the cycle of samsara on the path to enlightenment. This painting, in the collection of the Metropolitan Museum of Art, was purchased in 1969 courtesy of a bequest by Florence Waterbury. Its Accession Number is 69.71. This is a faithful photographic reproduction of a two-dimensional public domain work of art. This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author’s life plus 100 years.

This is my review of Nick Stockton’s “Time Might Only Exist in Your Head. And Everyone Else’s.” From Wired, 26 September, 2016. Published at 0600 hrs. I later modified this piece on 17 October, 2016. It keeps bothering me like a splinter in my mind. In its current revision, it comprises 2,537 words.

“Some physicists blame gravity for time. Others blame observers. Time, the arrow of time, the linearity of time flowing from the infinite past through the present into the indefinite future, cannot exist unless an intelligence, something sentient, exists to observe it, they say.

The moment when particle physics and classical mechanics merge is called “decoherence,” and it also happens to be the moment when time’s direction becomes mathematically important.

Mr. Stockton’s article points out that superposition in quantum mechanics means that an electron can exist in either of two places, a property called probability, but it is impossible to say where an electron is until that electron is actually observed.

Some physicists also say that what matters is not whether time exists, but what direction that time flows. (Claus Kiefer, “Can the Arrow of Time Be Understood From Quantum Cosmology?” in L. Mersini-Houghton and R. Vaas, The Arrow of Time, Springer, Berlin, 2010.) Read the rest of this entry »

Is the Universe Infinite?

“…one of the continuing debates among astrophysicists regards whether or not the universe is closed i.e. will not expand forever.

On the one hand, the model of a closed universe holds that there is sufficient mass in the universe so that the Big Bang explosion will gradually slow down and reverse due to the pull of gravity. In this model, all the mass of the universe involutes back into its unimaginably small and dense original condition until another quantum shift precipitates another explosion.

On the other hand, there are those who contend that the supernova data on distant galaxies confirms that there is insufficient mass for the reversal to occur, and that the negative expansion energy of space is causing our universe to expand forever.”
