Problems with mass?

There are "problems with mass" m.

 

Einstein said it is "not good"

to use "relativistic mass"..

 

(If it is not good,

then it must be bad.)

 

Is the cloth (of Swansont's physics) so whole?

Einstein does NOT support (all) his own stuff.

 

Is there a reason for that (lack of support)?

 

He (=Einstein) did NOT say "difficulty (with mass)";

he said "problems" (!, i.e. plural) instead.

 

Was he (=Einstein) hinting also at the problem

we now call "dark(=unknown) matter"?

(That's) Something just as difficult,

with no (satisfactory) explaination.

I.e. (The) nonsense does not fit (together

so well).

 

[instead Einstein recommended using rest mass,

prefering momentum

& energy

for moving bodies.]

 

I can accept rest mass,

& momentum;

but I can NOT accept energy E (conservation)

because we have "dark (=unknown) energy", too.

 

But I can accept 2*m*E, instead.

Why have you posted this in "Suggestions"?

Yes, many people think that "relativistic mass" is a confusing and unnecessary concept.

I doubt it. That is just mass. Nothing relativistic about it.

Indeed. Much clearer.

Why is dark energy relevant to conservation?

 

 

 

But I can accept 2*m*E, instead.

 

What is that supposed to mean?

 

You seem to have trouble with well established science but happy to make up nonsense.

Moderator Note

I have no idea why this is in support.

Telling others what you can and can't accept is not really a topic of discussion. If you have a model and/or evidence of some alternative physics, then post it already. In the appropriate section
