## The Chandra Angle !!

But the neutron stars are still quite large. This is because the electrons are about 1000 times as longer in how much space they require to sit in that system, than the neutrons. the neutrons are heavy hard attitude guys, they will go no where. But the electrons while occupy such a large couch are far far less heavier than are neutron. So they are basically whats called “soft”. They are long legged and eat less energy and when vanish the neutron stars have collapsed into an adjacent mass state but quite so very smaller in volume, a 1000 times, smaller.

So two things happened that are called supernovae (that is super star phenomena).

1. (Type Ia supernovae) White dwarf > induced by atomic disintegration due to gravity pressure > Core of the star

2. (Core collapse supernovae) Core of the star > induced further by emission of electrons > neutron star

## What are Gauge Potential, Whats a “Theory” in Physics?

Potential was, as said above, is, energy per unit mass or charge. So, we see that, in defining the higher quantity energy or potential (higher therefore closer to action, hence more fundamental or unified) we have to INTEGRATE the lower variable, here, Force, Field or (Any ) 3-vector. This entails therefore arbitrariness into the Physical solution when we solve for these quantities. These physical problems, as they involve differentials or integration, leads to a differential equation. Under further suitable physical conditions called eg laws of nature or physics, become whats called a wave-equation or for particles, equation of motion. We can say equation of motion for particles or equation of motion for waves if they are separate.

Now that we understand what are potential, field, vector and gradient and integral in relation to each other, comes requirements called as symmetry or laws of nature or laws of physics or in simple, boundary conditions to these differential equations known as, wave equation or equation of motion of particles OR waves. ( — which are separate so far )

These equations constrained by the conditions or restrictions which are attributes of physical observation, must therefore unite these variables (potential, field) into one entity which would satisfy the wave or particle equations of motion, the differential equations of motion in PARTICULAR ways only, known as Laws of Nature or Physics. So they become, from their 3-vector or scalar attributes, 4-vectors (or still higher, Tensors).

## Does Quantum Mechanics Apply to our life’s tiniest moorings?

The correspondence Principle. This guy which gets talked a lot has a simpler form at times. Again this principle is a specific or corollary of O = A*B with the understanding that even if one of the variable say A can be insignificant it still depends on the sequence of other variables which decides how significant the total outcome would be. Therefore given that B can be significant enough to over ride A’s insignificance the outcome O can be significant. In other words an event might correspond from a scale of insignificance to a scale of significance. Often a scale of insignificance can be the micro or nano scale and the scale of significance is reached because it is not insignificant. So there is a bridge between two scales, one of insignificance and one of significance. One of micro and one that is not micro but lies close. In all totality this is the reason why Quantum Mechanical effects can be carried to the Classical scale and this is known as correspondence Principle.

## Still some gravity !!

So talking about gravity fondly I have made a remark “Its not gravity that makes you fall”. You would be shocked as if you fell down but its not due to gravity but something else is at work, Am I a Physicist propounding a phantom theory? The actual statement I made is “Its not gravity that makes you fall, it only makes you fall FASTER”. That was known to Galileo, which we often very conveniently forget and make an erroneous statement that things fall because of Gravity. So it caters to the law of inertia also. So satellites would still fall irrespective of the absence or presence of Gravity. (although the inertia would mean they would be at absolute rest if we do not take into account enough of its past when something had hit it harder to slow it down or sped it up, in any case when enough history has been allowed to see that no forces or extra actions were disturbing its inertia, IT MUST BE MOVING AT UNIFORM MOTION without any debt to a force-bank called Gravity. If Gravity isn’t there the inertia is still the same and it would continue to be moving at the same speed, which as a specific possibility be ZERO)

So apart from the fact that Gravity only causes us to fall faster its also an erroneous fact to say: Gravity is caused by Masses. Or its innocuous looking twin-statement masses attract masses and thats called Gravity. It has two basic history why its often thought or said so. 1. History of how theory of Gravity developed. 2. History of how Gravity was taught.

## Did Newton know Quantum Mechanics?

My insight of the day. Quantum Mechanics makes Newton’s Law consistent in its two forms. Otherwise they would be inconsistent. So Newton knew some QMech. He knew 1. F=ma=mdv/dt and 2. F=dp/dt. These two are consistent in a framework where wave-particles are central. Because F=ma corresponds to particles and F=dp/dt corresponds to waves.

I will explain this later.
