4094 divided by 2 is 2047 male anscestors. The average volume of semen per ejaculation is roughly 3 mL on average.

2047 x 3 is 6141 mL of cum or 6.14 L of cum or about a gallon and a half.

The average fuel efficiency for cars in the US (sorry Europeans) is 25 mpg. This means if cum had the same energy density as gasoline you could travel roughly 37.5 miles on all the cum your male anscestors produced in the last 400 years.

That's only one ejaculation per male ancestor. You can safely assume that the average male ancestor ejaculated more than once. This would increase the distance traveled using the cum energy.

[-] PlaidBaron@lemmy.world 24 points 1 year ago

True. But Im only factoring loads splurted resulting in reproductive success leading to you.

[-] xantoxis@lemmy.one 12 points 1 year ago* (last edited 1 year ago)

I think it's fair to include jizz blown into your 12 generations of grandmas prior to your conception, though, because that cum was necessary to eventually lead to you being born. Scientifically speaking I think we're talking about all the man mayo that went into your grandma's hoochie coochie prior to your conception, but excluding any baby batter that went into the making of your previous older sibling. So we're only counting the clam sauce that led directly to you, not any of your siblings or any other combination of parents.

Cum mathematics is still a developing field.

[-] Tofubeef@lemm.ee 6 points 1 year ago* (last edited 1 year ago)

According to Leitzmann et al 2004 the average number of male ejaculations in lifetime is approximately 8700 times. That would be 26,1 litres of cum per male.

Edit: 2047 male ancestors would have produced roughly 53 427 litres of cum. Do we have data on energy density of cum?

[-] FattestMattest@lemmy.world 1 points 1 year ago

He's right, that would change everything

l/foundthemobileuser teehee

[-] ickplant@lemmy.world 6 points 1 year ago

I just KNEW someone would do the math. Thank you for your contribution to humanity.

[-] Burninator05@lemmy.world 4 points 1 year ago

This kind of insight is why I'm here. The next question is, "What is the energy density of jizz?"

[-] SJ_Zero@lemmy.fbxl.net 2 points 1 year ago

You think that's all they produced?

[-] PlaidBaron@lemmy.world 8 points 1 year ago* (last edited 1 year ago)

I dont have a degree in advanced theoretical cumonomics so I have to make some base assumptions.

[-] Psionicsickness@reddthat.com 2 points 1 year ago

Yeah but the base assumption is that all those ancestors only ever came once.

[-] xsh@lemmy.world 44 points 1 year ago

In Alabama you would need less than that though.

[-] FreeFacts@sopuli.xyz 26 points 1 year ago

With 12 generations, that would apply to pretty much everyone. It would be a statistical anomaly for anyone living today to have the full set of 4094 individual ancestors.

[-] gedaliyah@lemmy.world 42 points 1 year ago

I hate to break it to you but a lot of those are the same people.

[-] eestileib@sh.itjust.works 1 points 1 year ago

I was gonna say "I went to high school in Alabama and the math just doesn't work out that way"

[-] corvett@lemmy.world 22 points 1 year ago

There's gonna start being some overlap somewhere down the line

[-] ickplant@lemmy.world 7 points 1 year ago
[-] PlaidBaron@lemmy.world 4 points 1 year ago
[-] simplecyphers@lemmy.world 8 points 1 year ago

They just overlap much more recently

[-] Th4tGuyII@kbin.social 10 points 1 year ago

Good to know there's a long line of people already disappointed in me

[-] FinallyDebunked@slrpnk.net 5 points 1 year ago

this is fucked up calculations, for 100th generation we would need more humans than have ever lived

[-] TempleSquare@lemmy.world 22 points 1 year ago

Your flaw is assuming that a couple only produces one child. Many humans can share the same ancestor.

[-] Igotz80HDnImWinning@kbin.social 8 points 1 year ago

Don’t forget the recurrent loops of inbreeding. Reality is definitely less than 2^generation

[-] xantoxis@lemmy.one 6 points 1 year ago

Not even inbreeding, strictly speaking, when you go back that far. At 12 generations back you've got lots of ancestors with common ancestors, but they aren't so closely related that conceiving a child between them would be incest. Doesn't have to be siblings; very distant cousins would also reduce the number of total ancestors. They need not even have known their relation to one another.

[-] Tavarin@lemmy.world 4 points 1 year ago

By second cousins the rate of genetic abnormalities is the same as for distant strangers. You really don't have to go very far back for it to not cause issues.

[-] MxM111@kbin.social 2 points 1 year ago* (last edited 1 year ago)

That’s not his flaw, but OP’s.

[-] TheRealLinga@sh.itjust.works 4 points 1 year ago

I'm having trouble understanding this. Why would I need 4 grandparents?... oh... because 2 had a kid and 2 had a kid... then the 2 kids were my parents... so double that for great grandparents....

Damn I just answered it to myself. Guess I shouldn't ask questions while half awake

[-] Cqrd@lemmy.dbzer0.com 2 points 1 year ago

You do highlight that this ignores incest

[-] joneskind@lemmy.world 2 points 1 year ago

I don't get how the 400 years have been calculated here. 12 generations should be about 250-300 years maybe?

Anyway, that's of lot of cum indeed.
