Einstein’s geometrodynamics considers 4-D spacetime geometry whose curvature is governed by mass. But the FLRW universe considers a 3-D space of curvature k (+ve, zero, or –ve) with time as an...

We had an inconclusive debate today in class on whether mass is a scalar quantity or not. On checking the Internet I found that by using mass- energy equivalence, relativistic mass is found to be...

The Lagrangian of a tachyonic scalar field T can be expressed as LT = - V(T)( 1 - du T du T)1/2 When T only varies with the cosmological time t, the energy of density is rhoT = V(T)( 1 - dtT...

Consider the Goldstone model of a complex scalar field ΦΦ. It has U(1)U(1) global symmetry, so if we apply the transformation Φ→eiαΦΦ→eiαΦ the Lagrangian is left invariant
