Does this explain what generates gravity?

What happens to mass of both you, the water and the glass?

In order to travel at the speed of light, both the observer and the glass of water would have to be massless, otherwise they would carry an infinite amount of energy.

However, for anyone travelling with the glass of hot water at c, time would pass by quite normally.

I thought we had established that if you travelled at the speed of light you would not experience the passage of time at all.
 
SH on entropy here (seems it’s another subject in physics in which a lot of professional academics have differing views)

It was German physicist Rudolph Clausius who, in 1865, gave the first mathematical version of the concept of entropy, and also gave it its name.

It has been said that Clausius succeeded in coining a word that meant the same thing to everybody - nothing!

So that they can get notified immediately the next rubbish video from that YouTube channel comes along?

However, there may be some special interest YouTube channels for which subscriber support is essential to ensure they can keep running.
 
All thought experiments of course.

If only we could harness those thoughts! :cheerful:

Steve's been on the forum today, Bonsai. He may be in the huff with me, but he liked your your post 'SH on QM' yesterday.

Regarding the doyen of thought experiments, here's what he had to say:

“…Words or the language, as they are written or spoken, do not seem to play any role in my mechanism of thought." - Albert Einstein

And regarding your "24 V between the left and right ears", perhaps I should employ a dim bulb tester!

The Extremely Large Telescope (ELT), due for completion in 2028, has now passed the halfway point in its construction.

The ELT, located in Chile's Atacama Desert, will house a 39 m primary mirror and will be the largest optical and infrared telescope in the world.
