  • Why Sun is circular but star twinkles?

    The frequency of light is small because the energy or intensity is low. So you see twinkles. But light is still moving at the same speed towards us. It takes 4.5 years from some stars while taking 8 minutes from sun, both at the same speed. But with sun, the face of the sun or…

  • Triangles and Particle Physics !

    Phase Space. When we deal with what we call particle physics, we always have to bring into discussion; whats a phase space. Its the most basic thing to do, in that involvement. Its like each time we make pizza we have to think of whats the dough and whats the topping. At-least the theoretical and…

  • How simple is Relativity?

    On the top line is given what people like Galileo knew. Its called Gravity. It says as you go away from center of gravity your energy increases as the force of attraction you experience goes on decreasing with the increase in square of r, r is separation of you from the center of the gravity…

  • The photon saga.

    5. Photon is a zero mass particle (not a zero rest mass particle) and its deflection in gravitational field, called gravitational lensing is due to two reasons; i. single photon effective mass is due to the definite energy and momentum of the same. ii. multiple photons have non-zero invariant mass, hence they behave like any…
