Seconds
(mander.xyz)
Also angles
Would love to hear how mass is measured in seconds though
Set G = 1 and c =1. Then equations like r = 2m make dimensional sense.
My brother, that explanation is not nearly dumbed down enough and as with most math wiki is useless for eli5 stuff.
I think a lot of people understand the concept of light-seconds, which can measure distance in seconds.
Allow me to introduce the gravity-second. 1 gravity-second of mass-energy is enough mass-energy to have a Schwarzchild radius of 2 light-seconds.
I get what you're saying but am still too dumb to understand it lol
Size of a black hole.
Certain mass = certain distance
Distance = seconds
Therefore mass = seconds
Then I don't even want to be in same solar system with millisecond heavy object.
You most certainly don't, that's a radius of about 300km (186 miles) and a mass of 101 suns.
Even if you meant microsecond, that's 1/10 of the sun, and would be very disruptive.

Angle: seconds
Dessert: seconds
Motion: seconded
Rocket scientists be like:
Fuel efficiency: seconds.
Wait, how do you measure mass in seconds?
Time taken for me to eat that mass of hotdogs

Just as particle physicists measure everything in energy (eV to be precise...)
Mass? eV Energy? eV Distance? 1/eV Time? Guess what: 1/eV as well! This also means velocity has unit 1...
And the worst part: it turns out to be extremely useful!
Why is the astrophysicist wearing gloves? Is he trying to dispose of a body?
You don't want to know what an astrophysicist does in their free time.
Well the one I knew spent his free time doing community theater, having many of the women there go crazy over him (he was good-looking and charming), and then not sleeping with any of them because he was a wait-until-marriage religious guy. I don't think he was typical.
I intended to be an astrophysicist before finally settling on IT, and I was doing theater before life did its things and I had to stop. I'm kinda religious but not THAT religious (and my SO is an atheist so, really not THAT much).
Maybe there's kind of a type anyway.
Mass in seconds? How? I get mass in Joules, but seconds?
There are two possibilities I can think of:
- Orbit duration can be used to calculate mass
- The diameter of a star or the parallax distance on the sky (in arcseconds) can also be used to evaluate mass

I measure the mass of my stool by seconds it takes to discharge

Fun fact: Seconds are called seconds because the first breakdown of an hour is the minute, and the second breakdown is the second. Don't ask me the obvious question(s) because I don't know.
If by obvious question you mean “why is it called a minute,” that is because “minute” means “small.” So you have the first minute (small) part and the second minute part of the hour.
Me: not smart enough to understand
Brain: Quick! Say something to sound like you fit in!
Me: uh ... I just did the Kessel Run in under 12 parsecs!
But do you remember the Krebs Cycle?

I'm hungry for more; may I have seconds?
That may be relativists (they would actually measure anything in units of mass, with everything else defined through G = c = 1). Astrophysicists commonly measure mass in solar masses, long distances in parsec (or kiloparsec, megaparsec), short distances in solar radii or AU, and time in whatever is relevant to their problem (could be seconds or gigayears)
short distances in solar radii
I think astrophycisists and I may have a difference of opinion on the meaning of the adjective short
Everything should just be in eV. Particle physics natural units are the best.

angle: seconds
Rads. But radians are fine too.
all the same thing anyway
If you ever find yourself among theoretical physicists and/or astrophysicists and need a conversation starter, just ask about unit systems or unitless/natural measurement systems. There is no other profession that is more obsessed about that topic.
Just to put this here:
ħ=1
Please Sir, can I have some more?
Lash him! Ridicule him! This boy wants seconds!
Don't they measure distance and time by redshift (ie colour)
They normally use parallax-seconds, i.e. parsecs, for long distance objects.

Acceleration….
Sounds like that reduces to hertz, which I'm sure they'll just express in seconds.
They like to set the speed of light to be 1. That is dimensionless 1. It makes their calculations simpler this way instead of dragging some power of c everywhere like a loosely connected trailer on a dirt road.
When i took a particle physics class we measured everything in energy (eV). In this case of measuring everything in seconds, acceration would be measured in units of 1/s
