How does science work? And what's all this about quantum mechanics?

The speed of light

Post by bahman » Thu Jan 31, 2019 10:05 pm

The speed of light is a speed at which all events are observed simultaneously. I am wondering why this speed is finite.

"simultaneously"???????

speed of light - in a vacuum is 186k per second.

no matter - nor energy can move faster than that in a vacuum.

space expansion can (and all matter/energy in that space will move (sitting on the space) faster than 186k/sec) - at Event horizon's and edge of visible (WRT- us) universe (sphere edge of Observable Universe (Universe's event Horizon (WRT- us).

Yes. Time stops in a reference frame which moves with speed of light so all events are seen simultaneously.

Basically the speed at which everything is seen simultaneously should be infinite.

yes and how we learned that that that neutrons have mass - back in the 70's.

your point?

Neutron? What you are talking about?

Because that is the speed that is constant in all frame of references.

Possibly it's a typo and gaffo meant to say neutrinos?

Yeah, light forms the reference frame with the reference frame being determined by other frames as a frame in and of itself.

Light must be both simultaneous and have relatively different speeds.

For quantum particle with constant speed of light the time is ''frozen'' / stopped
But quantum particle needs time when it takes part in interaction with matter
( photosynthesis, photogenesis . . . . etc)
It can mean that quantum particle can have another speed ( relative ) and
another time ( relative )

The speed of light is probably somewhat related to the speed of Universe (History) growth, with the speed of time. mc^2 thus can be considered analogous to the universal kinetic energy of mass m.

no, no relation, the "speed" of the universe is due to the expansion of space, 97 precent of the universe is "Speeding" out faster than light.

light is without mass, only mass provides kinetic energy.
