These silly myths we still believe
When you call someone, the signal bounces off a satellite Every Time you Make a call
This is True for satellite phones which used by military, not our normal phones our phones works in much different way.
When you make a call, the nearest tower connects you to another phone via a vast network of tower-to-tower connections and buried cables.
99% of communication done by under ground cables.
The Great Wall of China is the only man-made structure visible from space.
The Great Wall of China isn’t the only man-made structure visible from space.
It all depends on where you believe space begins above Earth.
From the International Space Station, 250 miles up, you can see the wall and many other man-made structures. From the moon, you can’t see any structures at all — only a dim glow of city lights.
Lightning never strikes the same place twice.
Some places, like the Empire State Building, get struck up to 100 times a year.
Water conducts electricity.
Pure or distilled water doesn’t conduct electricity well at all.
The reason we get shocked when standing in electrified water is because water we come across will be contaminated by minerals, dirt, and other things that will conduct electricity.
The Sahara is the biggest desert on Earth.
Not all deserts are hot and full of sand. They need only be dry and inhospitable.
Antarctica fits the bill, since it receives only two inches of precipitation a year and has few land animals.
At 5.4 million square miles compared to the Sahara’s 3.6 million square miles, the Bottom of the World is a vastly larger desert.
Diamonds come from coal.
Most diamonds aren’t formed from compressed coal.
Instead, they’re carbon that is compressed and heated 90 miles below the surface of the Earth. Coal is found about 2 miles down.
Summer is warm because the Earth is closer to the sun.
The Earth is not closer to the sun when it is summer in the Northern Hemisphere — quite the opposite: The planet is actually at it’s farthest point from the sun during the summer.
It is always warmer during the summer because Earth is tilted. During its orbit, our home planet’s tilt allows the sun’s energy to hit us more directly.
Lightning causes thunder.
A scientific and philosophical nitpick here, but lightning is just a stream of electrons zapping from cloud to cloud or ground to cloud. This in turn heats air into a tube of plasma that’s three times hotter than the surface of our sun.
That tube violently expands and contracts nearby air, creating an unmistakable crack and rumble — not the flow of electrons itself.
