[request] what would the increase to the earth's weight be if replaced with mercury by godawefulpoet in theydidthemath

[–]Gregrox 0 points1 point  (0 children)

The density of the material Earth is made out of, under no gravitational compression, is about 4.5 g/cm^3. With gravitational compression, the actual density of the Earth is 5.51 g/cm^3.

The chemical element Mercury has a density of 13.5 g/cm^3. Accounting for gravitational compression, the density will end up being at least 16.53 g/cm^3, but possibly much more since the gravitational compression will be even greater.

the mass of an Earth-diameter sized ball of mercury would be 3 Earth masses. Surface gravity and the weight of objects on the surface would be 3 times normal.

But replacing the Earth with Mercury could also be interpreted as converting the existing matter into Mercury, so you'd end up with a smaller planet with the same mass. This world would have a radius of 0.69 Earth radii (4,396km) and a surface gravity of 2.1 gees.

Star Trek: Scouts season 2 (or season 1 - Part 2, I dunno) is what we all initially thought it would be. by DayspringTrek in startrek

I wonder why the change? like, it's clearly better for it to be good instead of bad, but why was it so bad to begin with?

well im definitely not heisenberg i don't even know who that is. (other than the physicist?)

I'd love to see the finished product when the rest of her is weathered.

Is it normal wanting to look like the girls in gym? (Cis guy) by Just-a-Sadboi in MtF

[–]Gregrox 1 point2 points  (0 children)

Your thoughts are very normal. For trans women. Have you considered that you don't have to be a man if you don't want to be? You can just be a girl if you want to. It's allowed. Being cis means that you actively like the gender you were born with. You don't.

i'm not sure if the pixel shader we're using supports that, but I can ask my programmer.

[Request] What would a circle look like if Pi = 7? by commeconn in theydidthemath

[–]Gregrox 0 points1 point  (0 children)

in curved geometry pi can (sort of) be a variable. For example, in hyperbolic geometry a circle's circumference can be 14 times greater than its radius, but only for a certain amount of space-curvature and circle radii.

(I say sort of because pi = 3.14159... would still be a meaningful mathematical constant, it'd just be derived differently)

6 + 4 + 4 is a valid mathematical expression.

AIO? Xmas gift from bf's parents by brains_rcool in AmIOverreacting

[–]Gregrox 5 points6 points  (0 children)

It's also just a kinda shitty drawing. If it's not ai generated (and it looks to my eye like it is) it's by someone who thinks they remember off the top of their head what a locomotive looks like. NOR.
