5 FACTS
- It can take a photon 40,000 years to travel from the core
of the sun to its surface, but only 8 minutes to travel the
rest of the way to earth.
The sunlight goes to the surface of the earth in the speed of light, while photons have to travel through
many masses of gases and vacuum spaces to reach the earth. Sunlight takes around 8 minutes to reach
the earth because Earth orbit the Sun at a gap of roughly 150 million km. The light travels at a speed of
300,000 km/s. The answer by dividing the digits comes to 500 seconds which is 8 minutes and 20 seconds. The photons are the
large particles of electromagnetic emission that define the atom properties of an electromagnetic movement. A photon is formed by
synthesis responses inside the Sun’s center part. Sun’s center is very dense, so the photons have to travel through huge hydrogen masses
and other particles. When a photon runs into the fragments like hydrogen it gets enthralled, the electrons in the atom get agitated, and then
it gets fired back out. As soon as these photons are away from sun’s atmosphere, they travel at a great speed to reach the earth. - Polar bears can’t be detected by
infrared cameras.
Polar bears are heated
perfectly due to a thick layer
of blubber under their skin
and a dense fur coat covering
their body. But their outer layer
stays the same temperature as the snow around them,
that’s why they are invisible in infrared cameras that are
aimed to detect the heat lost by a living subject.- It can rain diamonds on other planets.
Extra-terrestrial diamonds are very common. Microscopic diamonds not much larger
than molecules are abundant in meteorites and some of them retain a record of their
formation in stars before the Solar System existed. High pressure experiments suggest
large quantities of diamonds are formed from methane on the ice giant planets Uranus
and Neptune, while some extrasolar planets may be composed almost entirely of
diamond. Diamonds are also found in stars and may have been the first mineral
ever to have formed. The atmospheres of some planets have such high pressure
that they can crystalize carbon atoms and turn them into diamonds. - Superfluid Helium
Can Climb Walls
Researchers have known for decades
that if you cool liquid helium few
degrees below its boiling point of
- 452 degrees Fahrenheit (– 269
degrees Celsius) it will suddenly be able to do things that
other fluids can't, like dribble through molecule-thin
cracks, climb up and over the sides of a dish, and remain
motionless when its container is spun.
- The largest asteroid ever
recorded is a mammoth piece
of space rock named Ceres.
The asteroid is almost 600 miles in diameter. It's by
far the largest in the asteroid belt and accounts for
a whole third of the belt's mass. The surface area is approximately equal to the
land area of India. There is actually some debate over whether to refer to it as a
dwarf planet instead of an asteroid, even if it has mostly asteroid-like qualities.
