Here are some crazy things mirrors can do, including keeping wormholes stable enough to travel through time. Mirrors and phantom limbs can help us learn about the brain, and mirrors can also allow us to measure the distance to the Moon. Here are the craziest things about mirrors. So below there are some facts about mirrors.
Interesting facts about Mirrors
1. Mirrors And Time Travel
- This quantum electrodynamic force produces a mass-negative region of space-time between the mirrors, which could stabilize a wormhole, and allow faster-than-light travel.
- Theoretically, you could travel to the past, but not the future—so you couldn’t get next week’s winning lotto numbers, unfortunately.
- Another fly in the ointment is that the stable wormholes produced by the mirrors are infinitesimally small, so don’t plan a holiday to visit your ancient ancestors just yet.
2. Mirrors, Phantom Limbs, And The Human Brain
- Neuroscientists are a wacky bunch, but, amazingly, experiments using mirrors on patients with phantom limbs have allowed researchers to learn a lot about how the brain works.
- Using a “smoke and mirrors” style optical illusion, researchers placed mirrors vertically on a table and used them to reflected the patient’s intact limb—say a hand.
- This effectively superimposed the reflection of the intact hand onto the side of the phantom limb, so that—to the patient—it looked like they had both hands.
3. Mirrors Cause Hallucinations
- An illusion is conjured up when you stare at your reflection in a mirror. It’s the old Halloween trick that modern science is beginning to investigate.
- Try it for yourself. Sit in a darkened room, about a meter (3 ft) away from a mirror, and gaze at the reflection of your face for about 10 minutes.
- Keep the lighting as dark as you can, while still being able to view your reflection.
4. Mirrors On The Moon
- The Moon is, on average, 384,403 kilometers (238,857 mi) away from us on Earth. We know this so accurately thanks to mirrors.
- The distance to the moon varies, because of its elliptical orbit around the Earth.
- At its closest, known as perigee, it is only 363,104 kilometers (225,622 mi) away.
- At apogee, the most distant, it is 406,696 kilometers (252,277 mils) away from us.
