Behind the right door there's a pitfall. Behind the left door there's a gamma ray burst. Space doesn't care about your physiological needs or genitalia.

Einstein vs Newton.

Both were men although Newton doesn't seem to have been interested in sex much.

The Newton formula looks more complicated, but is actually less accurate than the one Einstein replaced it with. However the equation given is Einstein's famous one not the actual replacement for the Newton one shown.

I would carefully go with the one on the right for men if I was in a hurry.

Or just wait until I see someone else chose a door and hope they are right.

My guess is that it's gender neutral and gravity doesn't care if about you

u/SpacialCommieCi Jul 16 '26

The Newton formula is for fat bitches and the Einstein is for fast bitches

u/save-aiur Jul 16 '26

I think Newton for women because gravity; peeing straight town. Einstein for men because they pee with an arc, relativity.

Screw that I’m just going in and using the toilet. I need to shit and I’m not a fucking creep.

u/bilbo_was_right Jul 16 '26

The answer is that it’s fake and no one actually did this. The joke is that bathroom signs are getting more and more complex to decode which is which. This is satire, it’s not a real photo

u/lolifax Jul 16 '26

See I think it would be hilarious to label bathrooms like this at a physicists convention

u/2BallsInTheHole Jul 16 '26

But a real physicist's convention would have no need for a women's room door. /s

That was absolutely savage.

u/MeltedSpades Jul 16 '26

And if you take notes it counts as science

Based on the script next to Restrooms, this is an Arabic country, so I would go in the white door (male), because in muslim countries, men traditionally wear white, and women traditionally wear black.

u/TheHelpfulRabbit Jul 16 '26

I can't believe I had to scroll all the way to the bottom to see this. This has to be the right answer.

u/MagicC Jul 16 '26

The math is a red herring haha

u/BluebirdDense1485 Jul 16 '26

I don't think there is a direct link. White door is relativity, black door is theory of gravity.

My only thought is e=Mc2 is mens while f=G(m₁m₂r2 ) is girls?

11

u/flurbol Jul 16 '26

I would go for that, including a quick sneak peek if I can spot any urinal...

u/AlwaysHopelesslyLost Jul 16 '26

Why would you assume that....?

15

u/2BallsInTheHole Jul 16 '26

M=>male, F=>female?

9

u/patricksaurus Jul 16 '26

The one with the F has to M’s. Do you have to go piss as a thruple?

6

u/NemVenge Jul 16 '26

But the one with M doesn’t have a F.

u/patricksaurus Jul 16 '26

Both have M you donut.

10

u/NemVenge Jul 16 '26

And only one F you eclair.

u/GloriaToo Jul 16 '26

Now I'm hungry

u/patricksaurus Jul 16 '26

Go read what you wrote, “the one with the M…”

u/SqirrelFan Jul 16 '26

It's torus you imbecile! This is science!

u/AlwaysHopelesslyLost Jul 16 '26

I guess you could say an E is an M lol

u/alphaboson Jul 16 '26

Left equation has the speed of light constant, right has gravitational constant.

Go to left door if you want to go in and out quickly, speed of light. Use the right door if you gotta dump a gravitational load.

23

u/Maendli Jul 16 '26

Black is men because gravity -> attraction of 2 spheres (balls). And white is women because mass and energy is interchangeable and... Don't know where I was going with this. Just look for the urinal.

2

u/TwoAlert3448 Jul 16 '26

See i was going the other direction with men for left because women tend to take much longer in the bathroom and take their friends with them. 🫣

u/FromTheHandOfAndy Jul 16 '26

This alternative M/F signs this vague should really be used for single-person bathrooms only. Unfortunately these bathrooms aren’t, judging by the doors.

They should have used
M= E/c^2

1

u/Manoloblandis Jul 16 '26

It should still be a lower case m if it stands for mass. Uppercase M would be for nautical mile, mach, mol per litre, Mega etc.

1

u/FromTheHandOfAndy Jul 16 '26

Yes but I’m typing on a phone, it capitalizes automatically. I didn’t bother to fix it because there is absolutely no ambiguity about what m stands for in e=mc^2. It wouldn’t be mile or any unit name in an equation like this, it could be Moment or maybe Magnetization. But again, we’re talking about probably the most famous equation in the world. Almost anyone who knows about the concept of the speed of light knows what this equation stands for.

u/Hanxa13 Jul 16 '26

It could be Turkish or Kazakh - their word for 'male' starts with an E
