48 Scary Facts You Wish You Didn't Know: Can Our Brains Delete Memory?

They say ignorance is bliss, and sometimes, that couldn't be closer to the truth. Bored Panda recently compiled a list of spine-chilling facts that make us question everything from our own biology to the vastness of the universe. Whether it's the realization that your brain named itself or the haunting thought that you've already taken the photo that'll be used at your funeral, some truths are just hard to stomach.

The Neural Mechanism of Forgetting Unwanted Data

If these facts are too much to handle, science might have a solution. Researchers Jiangang Shan and Bradley Postle from the University of Wisconsin-Madison discovered that humans can consciously remove information from their memories. By dampening specific neural circuits, the brain can effectively 'edit out' unwanted content. However, some biological glitches remain terrifyingly involuntary.

• Your brain edits reality with a delay of 80–100 milliseconds. You're literally living in the past just to survive.
• Negative comments stick for 20 years, while compliments start to fade after just 6 weeks.
• Humans only see about 1% of the light spectrum. We're effectively blind to the majority of existence.

Cosmic Horrors and Biological Time Bombs

Beyond our minds, the physical world is just as unsettling. If the sun exploded right now, you wouldn't know for another 8 minutes. In the deep reaches of space, 85% of the universe's mass is dark matter, an invisible substance we still don't understand.

Closer to home, Prion diseases can lie dormant for over 10 years before becoming 100% fatal. Meanwhile, trillions of neutrinos pass through your body every second, and your skin is constantly shedding, turning you into the very dust that settles on your shelves.
