13 Life Mysteries That Science Can't Explain

The placebo effect and why cats purr are still questions we need answers to, watch to find out more things science can't explain.

Subscribe to ScienceN60 for more fun facts and information on why, how, and what to all of life's questions.

8. The Placebo Effect
The Placebo effect has been something that’s puzzled medical scientists for years and it’s because some people don’t actually believe in it while others swear by it. As long as you believe a pill will have the desired effect, it will. This has been shown to work in studies where a group was given the actual medication and the other group was given the placebo, which is just a sugar pill, and the placebo group claims their pill worked. No one knows why this works, but it could possibly be mind over matter.

7. Tomatoes
So did you guys know that a tomato is actually a fruit? Well did you know that this fruit is more complex than us humans? Yeah, a fruit. Apparently, a tomato has 7,000 more genes than a human has, 31,760 to be precise and we only have around 2,000 to 3,000 genes. Scientists aren’t really sure why and they haven’t been able to offer an answer either, instead, they’ve downgraded the C-value paradox into an enigma.

6. Left-Handedness
The vast majority of the human population is right-handed, more specifically around nine in 10 people and no one really knows why. Scientists know that the preference develops in the womb and that each side of the brain dominates certain functions in the body. This is what allows the two sides to carry out different tasks simultaneously. Scientists believe we began to prefer our right hands around 600,000 years ago when humans began using tools. Science hasn’t proven why left-handedness is a thing but some scientists just chalk it up to evolution.

5. A Blank Spot In The Universe
Do you ever look up at the sky and wonder what’s out there? Well, a group of astronomers at the University of Minnesota discovered a huge empty space in space. They happened to be taking surveys of the night sky when they found a giant area that was actually filled with nothing. No galaxies, planets, or anything. At first, they thought it could be a rather large black hole, but after some research, they quickly ruled that out. This spot is around 1 billion light years across, making the entire area about 6 billion light years of just nothing.

4. No Oxygen
I’m sure you all remember Jordin Sparks’ 2007 classic hit “No Air” right? Well, those catchy lyrics don’t apply to these animals. Found in the deep of the Mediterranean Sea, is a bacteria that has evolved and no longer requires oxygen to breathe. Instead, they require salt due to the oxygen levels being replaced by them. The discovered creatures are from the Loricifera phylum and are the first complex organisms that don’t require air whatsoever. When I read this, it honestly took my breath away.

3. A Cat’s Purring
Scientists today can’t quite figure out how cats create their purring, but the top theory seems to be that cats use the vocal folds in their larynx in order to produce the vibrations that help create the sound. The other puzzling question happens to be, “why do cats purr?” and no one has really found an answer. Cats actually purr in various situations such as when they’re being petted or even when they’re giving birth so I guess it’s kind of difficult to pinpoint, but her, I’m not a scientist.

2. The Voynich Manuscript
Throughout history, there have been multiple finds that come up indecipherable and we’re unable to truly discover anything about those finds.The Voynich Manuscript is a book that is stocked with images of botanical illustrations and written inscriptions that scientists have been unable to solve, however, they describe it as a type of medical reference. Carbon dating places the book near the 1400s, but since the text can’t be translated it’s almost impossible to figure out which civilization it belongs too.

1. Near Death Experiences(Life After Death)
Many people who have a sudden brush with death all claim to have similar experiences such as a feeling of warmth or peace, reuniting with deceased loved ones, and the ever popular seeing a light at the end of a tunnel. Scientists conducted a study back in 2015 that showed when a person’s heart is dying their brain is “peppered” with signals from the brain because it’s trying to stay active and that this induces hallucinations that cause a person to “see the light”. However, there is no solid answer to this mystery and we might never know
