The Upcoming 2017 Solar Eclipse, Sweeping America on its Totality

The simple mechanics of total solar eclipse exposes deep-seated fundamentals of spacetime. Total solar eclipse occurs in an event of earth, moon, and sun alignment such that moon fully blocks out the sun, casting its shadow on earth on the zone of totality. What remains on sky is sun’s corona shimmering behind the bulbous moon: Includes a rendering imaginatively known as diamond ring. On August 21, 2017 we will transit such a mesmerizing and momentous (literally!) event, and the eclipse experts, chasers and broadcasters have their bits and takes on this. Here are some genuine picks  (1, 2) for those interested in details, and here is an interactive map of the upcoming totality. This year the ASP (Astronomical Society of the Pacific) is holding its annual meeting just for the purpose of convening the ideas and topics around the wonder of total solar eclipse, particularly toward preparing the upcoming 2017 one. Those interested in cosmic magnificence, and like to partake in grasping the nature of reality, would truly benefit from the event.

As profound as the cosmic phenomenon itself is, total solar eclipse has been pivotal in our understanding of the way universe shapes and continues, and a linchpin in rubber stamping a revolutionary theory to be a truly authentic reality. On the May 29 of 1919, an English astronomer, physicist, and mathematician, Arthur Eddington, captured total solar eclipse on the island of Principe to validate Albert Einstein’s theory of general relativity. General relativity offered to blend gravity in the earlier picture of Einstein’s own special relativity, showing that gravity is the geometry of spacetime itself. The endeavor set out by Eddington and his team pinned the precise bending of light that occurs due to the presence of a massive body, in accordance with the principle of general relativity, thus fully endorsing Einstein’s Magnum Opus. Sun as a massive body too bends light that travel from distant stars, but we cannot verify such bending simply because sun’s intense glare blocks out the positions of distant stars. The shade of a total solar eclipse enables us to measure such deflections in the position of stars, as the sun observes its gravity.

The ramifications of general relativity are wide and far reaching, many we are still trying to fathom: From the origin of the universe to the existence of black holes (remember the fascinating Interstellar Gargantua), the phenomenon of wormhole, the prodigiously expanding universe to speculations of dark matter and dark energy to the recent detection of gravitational waves that employed state of the art technological sensitivity (10-16 cm in 4 km). General relativity has stood a century of experimental verifications, one recent with the validation of gravitational waves by LIGO (Laser Interferometer Gravitational-Wave Observatory), and some tests are still brewing that involve extraordinary precisions to further endorse general relativity, like appraising the contortions due to the black hole at the center of our galaxy or seeing the free fall of different materials in space missions.

The theory has shown the way universe propels, but also made our lives efficient on a daily basis. General relativity is a part of GPS navigation that we employ every day. Two well crafted titles that shed light on this deeply enriching theory are 1) The Perfect Theory by Pedro Ferreira, and 2) Big Bang by Simon Singh.

The first real validation of general relativity was ticked by the 1919 total solar eclipse. I will be attending the ASP meeting, and in the context of total solar eclipse, I will be speaking on the fundamental architecture of spacetime that the general relativity imparted.

For those interested in cosmic mechanics, deeper universal structure, or just scientific outreach to a wider community, it will be a good venue to participate and connect.

See you soon,

Proving it or Making Sense, Part II

Scientific Argumentation and Universal Logic in understanding the Universe

Part II

We were talking about how the alignment of “proving it” and “making sense” goes haywire with descriptions of deeper orders of reality, at times so much so that only the scientist in us happens to stomach them, and part of us still crave for an overarching clearer picture—causing an ever greater rift between the scientific endeavors and seeing the all-encompassing picture of reality, where we also reside. The reality is one, scientifically or otherwise. Science in no way takes us to a hazy confounding zone, but to see a true order we have to look at the scientific data with a broader, overarching perspective.

It’s just that with prodigious scientific advancements intricate details seep in, and “making sense” starts to fall outside the boundaries of scientific endeavor: because now it involves “us” seeing it differently. Like the tangled issue of the beginning of time that I brought up in the last post. No matter what rationality, the beginning of the universe via black hole, or the time having no beginning or end, as we are now learning, glaring quandaries nudge us for clarity—like what banged in the big-bang, or what’s the true nature of this timeless space-time.

As quirky as it gets, the beginning of time, whether through black hole or big bang (the linked article in the previous post argues for black hole as an alternative scenario of big bang), in the end could only be as mysterious as a colorblind entity chewing over the beauty of a rainbow. In seeing the reality, the time having a beginning seems a graver scenario than the case of an overarching continuum that flows eternally—simply because the earlier case incites further perplexities. The obvious one is how the time itself emerges out of nowhere. Some other blatant questions.

Arriving at the reality might take boxing of all the inputs and thinking outside the box. I would again have to pass on saying more on this here for the sake of space and post, and for the sake of you reading the book Physical Laws of the Mathematical Universe: Who Are We? instead.

In the earlier post I brought up the other mystifying subject that is infiltrating the bounds of scientific understanding—the emergence of consciousness in the continuum of space-time. An indispensible description, if we are to see a full meaning in the picture that has sprung from centuries of research and contemplation. Here again though we are struck with the oddity of joining a clear empirical deduction, from cosmological and quantum physics, to an order that appears to be abstractly—the nature of consciousness. We are puzzled over sewing part-science part I-don’t-know-what together.

I was looking forward to a recently held debate on the topic of Death contested between two teams of scientists, one arguing for the existence of life beyond death, and the other against. I happened not to watch the debate, but after finding out that the team against the idea won, I out of curiosity glanced bits of the video. You can watch it in Sean Carroll’s blog under the post Afterlife Aftermath. The neuroscientist who was trying to make his argument—upholding the existence of life beyond death—based on personal experience and neurological understanding belonged to the loser team [no pun intended]. The forlorn look of the neuroscientist was pitiful [not taking sides]. His struggle might have to do with our lack of scientific vocabulary to illustrate the subtleties of defining consciousness or our experiences, which could, in the end, provide a full picture of reality. The reality that science proves and we feel confounded about.

But in the end, in understanding the uttermost reality, the question of us or consciousness undeniably leads to the query of the truest nature of self. Read on Physical Laws of the Mathematical Universe: Who Are we?

Ultimately “making-sense” becomes foundational after certain threshold of “proving” is attained, for us to move forward, on scientific ground or otherwise. And basically it is “making sense,” at a common level, that not only authenticates but also translates the empirical doctrines.

All reasoning welcome,

Neeti.
