We have no idea what most of the universe looks like

We have no idea what most of the universe looks like

About 96 percent of the universe is made up of dark matter and dark energy, which are undetectable to humans. Scientists believe this is because the particles that make up these substances don’t interact with regular matter or light. Even though scientific discoveries are constantly being made about the stars, planets, and other galaxies we can see, it’s impossible to make conclusions about things that are invisible to our eyes.

A Laser Can Get Trapped In Water

A Laser Can Get Trapped In Water

Yes, really. A cool thing called total internal reflection is applied when pointing a laser beam through a container of water. When light travels through water, it’s slowed by the heavier particles in water,as described here. Thus, the laser beam effectively gets “trapped” in the water.

Bananas Are Radioactive

Bananas Are Radioactive

For one of our strangest science facts, bananas contain potassium, and since potassium decays, that makes them slightly radioactive. But this is one of those fun science facts you don’t need to worry about. You’d need to eat 10,000,000 bananas at once to die of radiation poisoning, Forbes reports...

Men are more likely to be colourblind than women

The genes responsible for the most common type of colourblindness are found on the X chromosome, the National Eye Institute explains. Even if women have the genes on one of their two X chromosomes, a properly functioning gene on the other one makes up for that loss. If men inherit the gene on the...

The human stomach can dissolve razor blades

On the rare occasion that you swallow a razor blade, don’t fret. The human body is more capable than you think. Acids are ranked on a scale from 0 to 14—the lower the pH level, the stronger the acid. Human stomach acid is typically 1.0 to 2.0, meaning that it has an impeccably strong pH. In a stu...

Hot Water Freezes Faster Than Cold Water

This fact seems counterintuitive, but it’s called the Mpemba effect, after a Tanzanian student named Erasto Mpemba who told his teacher than a hot mixture of ice cream froze faster than a cold one. Scientists now believe this is because the velocities of water particles have a specific dispositio...
