In The Name of Science

In the Name of Science

I had been truly excited about the initiative I took up to comprehend and discuss the nature of an overarching reality, of which we are part, by the way of science. And although a credible number of individuals showed a true enthusiasm, I found myself somewhat dumbfounded on the prospect of seeing only a modest chunk of aficionados. I was imagining an abounding passion.

The renderings of science are often seen to be niche based. We are very familiar with reconciling mathematics and physics, although mostly for the dependency of formulating the physicality. Not them as interchangeable truths of an all-encompassing phenomenon, offering discrete ways to see a larger picture of reality. The situation is worse between other academic disciplines, such as physical sciences, biology, medicine, psychology, philosophy, even consciousness. As if they are all discrete independent truths, and not belong to an all-sweeping single phenomenon.

The niche based tightness often run between sub-disciplines of a subject too, where two interpretations from different sub-divisions are seen as independent pieces of information, and not as two aspects of the very same game. A good example to highlight this is the observed of quantum physics and cosmology. Worst still is the belief that the way we perceive the universe directly isn’t a part of the whole game, or that resides beyond the texture of science.

Having a niche appears to be more about marking boundaries rather than gathering their deft pitches toward seeing a bigger picture of an all-encompassing truth. Indeed, specialized scientific branches progress to benefit in health, better life and world order, but in not taking an overarching view, beyond specific boundaries, an along-the-way picture that emerges only from the voice of science as a whole, gets compromised.

Joining methodic alcoves toward grasping the truest tapestry just for the sake of science is slightly different, decisive nonetheless—also leisurely for many of us. So getting back to the original point- why aren’t we seeing a teeming pool of us hungry to sense the deepest order of the universe just as a pure knowledge. Here is what you will find interesting.

A survey shows that the subjects on which the top 100 most cited research papers are perched are biological techniques, bioinformatics, phylogenetics, statistics, density functional theory and crystallography. Not Albert Einstein’s relativity, or big bang, or quantum field, or mathematical symmetry and groups, all of which contributed immensely toward understanding the nature of universe, just as pure information on the fundamentals.

As with any drug, side effects can be a sperm donor? Any healthy male who is middle-aged, or older, your viagra pills without prescription Spam folder is most likely the same.
I felt very sympathetic to what the last paragraph of the survey article conveys. Here it is verbatim:

Still, there is one powerful lesson for researchers, notes Peter Moore, a chemist at Yale University in New Haven, Connecticut. “If citations are what you want,” he says, “devising a method that makes it possible for people to do the experiments they want at all, or more easily, will get you a lot further than, say, discovering the secret of the universe.”      

Practical issues and way to a comfortable life, and ease at work are all great causes. The bare beauty and grandeur the universe would still lure many of us to assimilate and ponder the underlying trueness of the infinite and infinitesimal.

So I am not altogether surprised by a smaller crew on board, who cravingly seek the subtleties of the universe just for the heck of it.

Will be back soon.

Universe Needing to Inflate

Universe Needing to Inflate

In the evolution of the universe there conceivably occurred an instance of prodigious expansion, so rapid that the universe’s once infinitely dense miniscule glob swiftly stretched—light years across in a fraction of a second. The incident is commonly referred to as inflation. As enigmatic as it may sound, the scenario of expeditious growth does have healthy outlooks to support of the way we envisage the universe based on scientific judgments.

Inflation explains why the universe we find ourselves in is flat; it explains away why the observable universe is constitutionally same whichever side we look, or is largely isotropic. First proposed by Alan Guth, the stunt of inflation further goes on to explain the unification of the two grand principles, general relativity and quantum mechanics. That is, the inflation exposes a way to realize that a gravitational wave is just a mere transfiguration of quantum fluctuation. That is why the conclusive detection of gravitational wave by BICEP2 (Background Imaging of Cosmic Extragalactic Polarization 2) was a much celebrated event, especially for scientific community, because it was a firsthand glimpse into the universe undergone inflation. Although several reports following the initial discovery wavered between optimistic and skeptical standpoints on having identified gravitational waves—we very likely saw it; no we didn’t; we probably did; no probably not—over all the observations do seem to provide a rational evidence for the beat of gravitational waves from the dawning cosmos, supporting the occurrence of inflation.

Here is the entertaining part. Methodical measurements suggest that this abrupt unfurling of the cosmos was rapider that the speed of the light itself. Truly intriguing: because the speed of light is the maximum attainable speed as per the well-credited Einstein’s special relativity. As delightful as it is to relish, when comes to explaining such an oddity we are struck with the quandary of seeing the space-time to have momentarily broken the rule by which it itself flows. From special relativity we know that the time dilates to accommodate speed, but in an instance of a speed surpassing the light how do we see the time as a part of space, in the usual texture of space-time?

In justifying a speed faster than that of light, where time still permeates the texture, we probably have just one way of seeing the picture—An order where the space-time doesn’t flow but manifests as discrete units. This is not something entirely new I am referring to here. It is suggested in Einstein’s special relativity that the speed of light is constant for all observers, and this basically means that two objects approaching with different speeds would both be seen at once—not the one with the higher velocity first. Thus, when it comes to the light-speed the space-time arena manifests. For velocities within the light-speed the time shifts—the higher the speed the lower the ticking of the time. In a possible event of surpassing light-speed the flow halts, and the manifestation transpires. In all the scenarios though, the time is indeed valued to be inextricably blended with the space.

Besides figuring out the dilemma of how exactly the inflation came about, the idea of inflation itself is truly insightful, and as stated above it does iron out two of the deepest mysteries of the cosmic plane: one that the universe is flat on all sides we see. But the cosmic structure appearing flat doesn’t necessarily mean it is flat. The geometrical appearance is a matter of perception. Encountering an object is an advent of electromagnetic radiation from that object impinging the eye, which doesn’t impart much information on how the space itself is structured. We can surely assign closeness and farness to an object but cannot refer with certainty whether the space-time is flat or infinitely curved, or even permanently shapeless.

Second is the isotropy. The universe being isotropic is the strongest evidence in the support of inflation. In fact the conception of inflation was contrived by Alan Guth for the need to explain the mystery of cosmic isotropy.

The cosmic isotropy that is supported by inflation, on the other hand, signifies the continuum of a single overarching tapestry from the initiation, billions of years ago, to our vision.

The full-length reality entails that the cosmic plane and quantum décor, Newtonian mechanics, Einstein relativities and particle fields all harmonize to announce a single continuum. And the   inflation once again gives us a way to see the metamorphosis of the minute quantum fluctuation to a gigantic gravitational wave—where seeing the unification of quantum and cosmic planes becomes conceivable.

But in the above schematic there is a slight glitch, which is to justify the continuum of the palpating “multiverse” that we make out from purely quantum studies. To overcome this perplexity it is proposed that different regions of the universe experienced their own separate growth (or inflation)—what we glance at is just one of those regions.

Seeing the cosmic and quantum structures as one field involves the principles of Einstein’s relativities, quantum field and how we perceive the universe directly, but I will end this post here, and leave the matter for the coming ones.

I will be back shortly.
