8 Lesser Known Science Facts That Will Make You Say "What"

Why don't more people really appreciate science? Personally, I believe that this has something to do with science communication and the way we teach science in our schools. With this in mind, here are some wonderful scientific facts that I hope will inspire you to learn something new every day. 

1. If two pieces of the same type of metal touch in space are bound together and permanently stuck together; this amazing effect is known as cold welding. It happens because the atoms of each piece of metal have no way of knowing that they're different pieces of metal, so the lumps come together.

2. Since Mars has less mass than Earth, the surface gravity of Mars is less than the surface gravity of Earth. The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you weigh only 38 pounds on Mars. And also Mars has about one-third the gravity of the earth; so the rock that fell on the mars would fall more slowly than the rock that fell on the earth.

3. A sound of 1,100 decibels would create so much energy that it would act as an immensely high quantity of mass. This would, in turn, create enough gravity to make an extremely large black hole. More than our observable universe.

4. If the Earth suddenly stopped spinning, the atmosphere would still be in motion with the Earth's original rotation speed of 1100 miles per hour at the equator. This means that rocks, topsoil, trees, buildings, animals, and so on, would be swept away into the atmosphere.

5. The hardest substance ever discovered in nature is a limpet (sea snail) tooth. They have a tensile strength between 3 and 6.5 gigapascals, breaking the previous 1.3 GPa spider silk record. And snails' teeth can also withstand the amount of pressure that can turn carbon into diamonds.

6. Cockroaches have a higher radiation tolerance than other animals (especially compared to humans), although this would only help them survive the long-term radioactive contamination that could be caused by a nuclear explosion. Even, They can survive radiation levels up to 15 times higher than humans, which means that they are more than likely to withstand the after-effects of a nuclear bomb explosion.

7. For decades, physicists thought that there was no limit to how fast an object could travel. But Einstein has shown that the universe actually has a speed limit: the speed of light in the vacuum (that is, empty space). Nothing can travel more quickly than 300,000 kilometers per second (186,000 miles per second).

8. A non-Newtonian fluid that has both liquid and solid properties. In short, if you apply sudden force (like stomping on or running across it) it's acting like a solid. This means that you can run on their surface without sinking or drowning.

Hope you liked it.
