Good informative discussion!

Thank you very much anorlunda for valuable article. Will study it with care.

Electromagnetic or gravitational wave carries energy and momentum from place to place as,I understand.Does it imply that such waves only can carry information and if their energy gets dissipated as heat, the information contained is lost. Is this information content is to be decoded by human...

Sorry for hurridly writing the question .Here , w is angular acceleration of taurus w.r.t a perpendicular axis to plane of taurus through centre. Ignore viscus drag. I need to calculate change in internal energy per second in both cases. Not getting idea to start. My basis of thinking is an...

Summary:: How internal energy changes in a acclerated cabin. There are two tourus shaped insulated closed pipes containing equal amounts of ideal gas under same conditions. B has a adiabatic partion wall. If both are to change angular velocity by w radians per second. How internal energies...

Let M is original supercooled water and m is mass of lump formed. Heat lost 80 m Heat gained(M-m)(0-(-10)) So m/M=1/9

This temperature cannot be found here. If I assume this temperature 0 degree,I get answer as 1/9 .But,I am doubtful.

My argument is that heat lost by lump of mass converted to ice will be gained by remaining water. But how do I find heat gained ?

Can we say Pauli exclusion principle is evident in electron degeneracy pressure. Also at neutron star stage ,is there too some principle like Pauli exclusion principle at work?

Is degeneracy pressure created due to Pauli exclusion principle able to create some waves? Also at neutron star stage similarly are there waves created may be of higher energy? Can we talk of some harmonic motions in these stages?

If after a vaccine of suppose 70% efficacy is given to a person ,he will develop antibodies . Now after a month new vaccine comes with 95% efficacy. Can he be injected new vaccine ? What about antibodies already in him? Can many types of antibodies remain and have no adverse effect and do not...

A cabin is accelerating with acceleration a .To apply Newtons laws inside it ,we need to include an acceleration -a. Now if this cabin is rotating about a point in a plane,can we apply Newtons laws in it? How?

Thanks!

Had read in Carlo Rovelli's book.

As I understand space time fabric is exclusively the Gravitational field according to Einstein.So every field wave or interaction is contained in the Gravitational Field.This fabric of spacetime(gravitational field) is having properties of inertia and elasticity that is why gravitational waves...
