I believe if you gently step over the event horizon of a black hole, the light reflecting off the back of your head will wrap around accretion disk and back into your eyeballs. It requires a bit of setup and is kind of a one-time thing, but you’ll get a much better view than you could get with a mirror!
Small correction: You’ll want to be at the photon sphere, not the event horizon (1.5x the Schwarzschild radius). You can theoretically hover there for an unlimited time, and even escape, as long as you don’t mind the immense acceleration necessary. :)
I tried this. On an unrelated note who’s up for some spaghetti?
This didn’t work for me at first, but I tried it a second time and it actually worked! You weren’t kidding about it being a one-time thing though, because I haven’t been able to do it since.
A friend of mine tried but it showed him with no-hair
I see what you did there… I think… My head hurts…
Two mirrors.
A hand mirror and the bathroom mirror.
Just to add on: face away from the bathroom mirror and look into the hand mirror, angling it until you can see the reflection of the reflection of the back of your head.
(Figured if someone out there actually needed this advice, the actual method might not be totally obvious to them without explanation.)
Easiest way is to stand with your back to a large bathroom mirror or vanity while holding up a hand mirror to your eyes to look back at the big mirror.

- Two mirrors.
- Take a photo or video holding your smartphone behind your head pointed at you.
- I suppose if you needed to see it in roughly realtime, you could figure some way to live-stream your smartphone camera to a screen in front of you.
The only other ideas that are coming to me are joke answers like “bend over backwards and lay the back of your head on the bed of a photocopier” or “visit a hall of mirrors.”
What’s your purpose for doing so?
What’s your purpose for doing so?
Curiosity, of course!
Two mirrors, a camera, moving faster than light so that you can catch the photons coming of the back of your head.
Scalping?
If you have an iPhone and an Apple Watch open the remote camera app and point your phone at the back of you head and stare at you watch. If you have an iPhone and a Mac you could use the remote webcam feature.
I’m sure you can do the same things on android with 3rd party apps.
Portals.
Three mirrors. A tri-fold mirror works great.
I cut my hair with a mirror they sell online. It’s 3 mirrors and it can hang from a door. You adjust the mirrors on the side until you can see most of the back, turn your head and look thru the other mirror to get the rest
Turn your head side to side really really fast.
- Find a hard surface like a concrete wall or metal desk.
- See if you can find someone to explain what a leveraged buyout is to you.
- Proceed to bash your head into the surface until it makes sense that a company could do that to another company.
You can now see the back of your head!
Bonus step four, go into business as a PE firm and help destroy American economy while enriching the wealthy!
how removable are your eyeballs you know what forget I asked just hold your phone pointing into a mirror and look away so the mirror sees your backhead.
if you have two devices you can videochat yourself. or screencast your phone to your tv. be sure to mute first.
- Find yourself a Spacetime Bender guru, preferably with a boomerang shaped birthmark on his scalp
- Become a generational talent
- ???
- Contemplate your inevitable bald spot
