Having hard time finding Dark matter]]>

But what about spacetime diagrams, like these two equivalent diagrams that "explain" the twin paradox.

I claim they support what I said: the lengths of timelines depend on which

Points for discussion:

1. Is this phenomenon causal?

2. Is it simply Heisenberg Uncertainty principle on Energy/Time, then should it not be prevalent everywhere?

3. What is the minimum and maximum possible energy of such particles? If there is any limit.

3. Are we looking for some cause behind or the concept is fully consistent requiring no further research on basic aspects?

4. Will the Quantum Gravity, throw some further light on this? Point is,...

Quantum Fluctuation : Causal]]>

For HR.

1. The associated fluctuation is required to take place at just this side of Event Horizon.

A. What is so special about EH or just near EH that such fluctuation to take place? For a very massive BH, the EH is as tidal free as any other region of space, no big deal curved space time at...

The above equation stands as physical knowledge. It is taught in physics and stands to reason. However my question is this: does this equation put to use produce EVERYTHING?

1/1*100

1/2*100

1/2*100

3/1*100

3/2*100

3/3*100

...and so on, to one hundred. It is quite possible to imagine the graph produced from such a formula: it is a little like a finger print (very pretty.) But does it involve EVERYTHING?]]>

The answer is two!

Put simply: (x+1)-(x-1)

...it is the question that drives us. ]]>

Two points for discussions..

1. Are we done with know all of science, is there any field where we know very little and much more work need to be done? Similarly what are the areas where we can safely say that we have mastered?

2. Is there any need for alternative theory in any field of science. Any theory which requires overhauling but not happening due to various reasons?]]>

Now take 2 white Knights at their original positions on a blank board. They are on a journey to cover all the 64 squares without repeating any square. They move in sequence in such a manner that they are never in attacking position. What is the maximum number of moves till then they avoid the attacking position?

Can it be solved...

Chess Problem]]>

It sounds a bit strange to me.]]>

Spin of earth or macroscopic object appears well understood classically. But what about spin of fundamental particles. Like that of electrons, protons, neutrons and quarks?

How do these particles attain spin? Is the spin of all electrons (any particle) same in unforced condition? Why only 2 states of spin (Pauli), ideally there could be infinite spinning orientations.]]>

The vertical line: \(x = 1\)

The unit hyperbola: \(x^2 - y^2 = 1\)

The unit circle. \(x^2 + y^2 = 1\)

If we ignore parts left of the y-axis for now, we can describe each of these curve's x-values as functions of y.

The vertical line: \(X_{0}(y) = \sqrt{1}\)

The unit hyperbola: \(X_{-1}(y) = \sqrt{1 + y^2} \)

The unit circle....
