Top Quark

About: top quark: mass of world's heaviest elementary particle found | fox news

It is interesting the definition of mass in the article
source: ... Four separate experiments found a joint value for the top quark of 173.34 (+/- 0.76) gigaelectronvolts divided by the speed of light squared, scientists announced Wednesday (March 19) at a physics conference in Italy.
...
i.e. a voltage (potential energy) divided by the speed of light.  It is counter-intuitive even though it is Einstein's usual equation written from the mass perspective:
M=E/C^^2
Someday I will go further past Einstein's relativity to understand how the speed of light got in there. Don't send links to me I already have some. I tend to think the speed of light is infinite with context showing up as some particular harmonic of the light wave being measured demonstrating a particular speed. Most of quantum physics is counter-intuitive anyway. See this article on quantum entanglement.

Here is Wikipedia on weight vs mass.
source: ... In everyday usage, the mass of an object is often referred to as its weight though these are in fact different concepts and quantities. In scientific contexts, mass refers loosely to the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight refers to the force experienced by an object due to gravity.[1]
...

Therefore in empty space I guess I could beget a massive turd that weighs absolutely nothing.

well that "within a universe which is being cranked at a specific rate, you cannot possibly change any faster", was just the assumption which made the equations work.
quote refers to what?
it answers, me thinks, your inquiry  "to understand how the speed of light got in" Einstein's equations.  i was, speaking for myself , not quoting,  but had only bolded the word "assumption".  In other words, if you make that assumption and describe the rest of the known ways relative motion happens, you get those equations.

... or said differently.  don't look for the speed of light in the equations being implied by other elements, rather recognize that the speed of light being a limit was assumed.  how Einstein had the gall to assume that limit is something that you would need to ask him.
... strange that nobody else seemed to have that much gall.

Yeah - still not intuitive.
What's not intuitive?  Specifically.
Why not the length of the king's dick or foot?
    The equation purports to relate three items:
speed - something moving over a distance
mass - quantity of some substance (something)
energy - the capacity to do work/activity - normally moving an object (something) over a distance
this would seem to hold all masses of substance the same & even hold light as a mass thingy.
Energy seems to be a munge-up in Wikipedia - I don't want to go there. This item was basically a bookmark on the units of mass of a very small thingy for further research laste.
