Chiara's latest activity

You need your ear to compare the tuning fork and the piano - or some other sense. That uses electromagnetism. Reading signs in Braille...

Measuring weight uses a scale. Even reading a hand on a watch uses photons to determine if the hand went over a line.on the scale. I...

Indeed. But is there a really precise measurement device that does not count photons?

A text I read some weeks ago claimed that all measurements count photons. Indeed, even a thermometer requires light to be read off, and...

"Black" means: "It does not shine". This is the prediction of general relativity. A non-zero BH temperature means: it does shine, it...

Jacobson gave a purely mathematical proof: the entropy of black holes, their temperature, and their mass/energy, taken together, imply...

He showed in his paper that the entropy of black holes, their temperature, and their mass/energy, taken together, imply the field...

The abstract starts with "It was conjectured 30 years ago that gravity could arise from the entropic rearrangement of information." It...

:welcome:

Jacobson’s work (1995) [1] demonstrated that Einstein’s equations can be derived from thermodynamic principles, suggesting gravity might...

I am new here. Above all, I am passionately curious about fundamental physics.
