Science is always been a fascinating subject. We collect some science facts you would like to read.
1.Due to Heisenberg’s uncertainty principle (which basically states that precise location and momentum of any object in the universe cannot be defined simultaneously), even if we are able to achieve an absolute zero temperature (-273.15 deg C), atoms will have an inherent vibration associated with them. This goes against the common conception that atoms will come to an absolute rest at an absolute zero temperature.
2.The speed of light is an upper limit of the speed of an object having mass in the universe. Only photons (zero mass) can travel with the speed of light. In-fact as photons have zero mass, they can not travel at any other speed but the speed of light.
3.The speed of light remains the same in any non-accelerating frame of reference. In other words, if an observer is stationary or even if is traveling with a constant speed of speed of light, he/she will always record the same value of the speed of light (2,99,792.458 km/s).
4.With an increase in the speed of travel, space-time starts to shrink in the direction of travel. Although this effect is irrelevant at lower speeds, it starts to amplify as the traveling speed approaches the speed of light. It is the fundamental phenomena which are responsible for keeping the speed of light a constant in any non-accelerating frame of reference. It is also responsible for the production of a magnetic field around an electric current.
5.Just like an external disturbance creates ripples on the surface of a fluid (stone is thrown in the pond), heavy objects (rotating black hole, dancing-spiraling black hole pair/ neutron star pair) or high energy events (explosion of star-supernova) create ripples in the fabric of space-time itself. These ripples, also known as gravitational waves, travel outwards from their source at the speed of light and literally expand and shrink whatever that comes in their way (you, me, Mother Earth too). Please click on the link to listen to these gravitational waves as recorded by LIGO (Laser Interferometer Gravitational-wave Observatory).
6. A single solar flare can release the equivalent energy of millions of 100-megaton atomic bombs. A solar flare is a sudden flash of increased Sun’s brightness, regularly observed near its surface.
7. If you spin a ball as you drop it, it flies.
The Magnus effect, which occurs when the air on the front side of a spinning object is going the same direction as its spin, which means it gets dragged along with the object and deflected back.
Meanwhile, the air on the other side of the ball is moving in the opposite direction, so the airflow separates.
8. Polar Bears are nearly undetectable by thermographic cameras, due to their transparent fur.
9. Butterflies taste with their hind feet, and their taste sensation works on touch – this allows them to decide whether a leaf is edible or not.
10. There’s a migraine medication (Sumatriptan) that can actually cause some people’s blood to turn dark green when taken in a large dose. It causes something called sulfhaemoglobinaemia which basically means there’s sulfur in your hemoglobin. That’s not exactly a good thing. Don’t bleed green folks.
11.People actually avoid information that threatens their happiness and worldview. They will enclose themselves with things they agree with, basically creating their own reality. According to researchers at Carnegie Mellon University, “People often avoid information that could help them to make better decisions if they think the information might be painful to receive.” It’s not, “THOSE ignorant people!” It’s actually all of us to one degree or another.
12. Coffee is the most universally used recreational drugs as we considered. It’s also one of the most addictive. It’s an energizer, like cocaine. When someone says they need a cup of coffee or that they are irritable before coffee in the morning, they aren’t pretending. They may be having to withdraw symptoms.
13. Honey, when sealed, does not spoil or rot. It’s literally edible thousands of years later. Egyptian tombs have been found with jars of still edible honey inside.
14. The weight of the average fluffy, cumulus cloud is a little over a million pounds. Clouds are made up of tiny drops of water dispersed over a large area (much larger than it seems from the ground) and water is very heavy. They are ethereal in looks only.
