Science and Technology Trivia
A car traveling at a constant speed of 60 miles per hour would take over 48 million years to reach the nearest star (other than our sun), Proxima Centauri. This is about 685,000 average human lifetimes.
Scientists recently announced the discovery of a new planet orbiting a star that's practically next door - relatively speaking. There's also the possibility that the system might contain a second planet. The star, Epsilon Eridani, is only 10.5 light years away — which is just down the block in astronomical terms — making it the nearest star known to have such a planet. The new planet appears similar to Jupiter, but half again as big. The discovery was made by a team of researchers led by scientists at the McDonald Observatory at the University of Texas at Austin.
A cosmic year is the length of time it takes the sun to complete one revolution around the center of the Milky Way galaxy. That's approximately 225 million earth years.
The sun is estimated to be between 20 and 21 cosmic years old.
It takes a plastic container 50000 years to start decomposing.
Lab tests can detect traces of alcohol in urine six to 12 hours after a person has stopped drinking.
Sound at the right vibration can bore holes through a solid object.
The color black is produced by the complete absorption of light rays.
There are 3 golf balls sitting on the moon.
The Sun has a diameter of 864,000 miles.
Air is denser in cold weather. A wind of the same speed can exert 25 percent more force during the winter as compared to the summer.
An iceberg contains more heat than a match.
Every cubic mile of seawater holds over 150 million tons of minerals.
A temperature of 70 million degrees Celsius was generated at Princeton University in 1978. This was during a fusionism experiment and is the highest man-made temperature ever.
Bacteria can reproduce sexually.
The pressure at the center of the Earth is 27,000 tons per square inch.
There are five tillion trillion atoms in one pound of iron.
German chemist Hennig Brand discovered phosphorus while he was examining urine.
The densest substance on Earth is the metal "osmium."
The clock at the National Bureau of Standards in Washington, D.C., will gain or lose only one second in 300 years because it uses cesium atoms.
