it's a valid concern, but then you have to be in the same dimension as something to fuck it

don't ask me how i learned this
How did you learn this?

Okay so I don't understand that physics paper. I can't even figure out which terms he supports using.
He argues that the correct way is to use E0=mc2, where m is the invariant mass - aka rest mass, and the only kind of mass that should be used. The subscript 0 for mass is then not only unnecessary, as there's no need to indicate this being a different kind of mass if there's just one kind to choose from, but also conflicts with Newtonian notation where it's not used (it's just m) despite being the same thing.

The above equation describes the energy content in the rest frame of the system with mass m.

This means, among other things, that you can't use it to get the 'mass' of a photon, since there is no such thing as a rest frame of a photon.

As follows, to describe the energy content of a moving body, you need to use the full equation E2=p2c2+m2c4.

The author argues that using the relativistic mass leads to misconceptions, such as mistaking the relativistic mass for the source of gravity in GR (which it is not - it's energy and momentum).

Dan and Arin of the Game Grumps actually looked at Rosalina porn on the rule 34 site during an episode and talked about the contents of said porn extremely vaguely (I quote: "I am learning things about the human body.") during that episode

You can't fuck a cartoon because cartoons are in two dimensions and you'd slice your dick off due to having touched the incredibly slight area of contact with any amount of force.

Relativistic mass isn't even useful as a coefficient between force and acceleration in relativity, because said relativistic mass changes depending on direction you accelerate in. "Relativistic mass" concept is just completely absurd and there's no way around it.

Sure?
wow

EDIT: Is this what e-fame feels like?
The first hit's free, friendo.
Now get shit posting (or create content hahaha who does that)
Also aaah timezones, what is happen, whenwhere
I have an unexpected free hour, I want to fly west forever

An international date doesn't sound so bad...
Also wow this rp has been hiatused for 2 weeks and launched the same hour I did. Been looking forward to it, will be tough to be active :/

Sounds hilarious. Not too surprising, this is the internet, internet shows are bound to toe the line on what's appropriate. The internet is more lenient than TV.

Okay, I think that helped. So objects with high velocity experience increased gravity, but this is not due to increased mass?

On an unrelated RP forum, spam bots have decided to attack my 6 months old birthday thread.
But non-spam bot people are now posting me a happy-bday posts, like WTF no one reads date of post anymore?
