Interesting Scientific Discoveries You Should Know About
Today, we have science to thank for the incredible technologies that we usually take for granted. And we can almost explain any phenomenon around us – for instance, we have many theories that can explain light, such as James Clark Maxwell’s Electromagnetic Theory of Light to Heinrich Rudolf Hertz’s Photoelectric Effect. Furthermore, we have many inventions that make our lives easier such as various modes of transportation, alternate sources of energy and other conveniences. Here are a few scientific discoveries of the 20th century that you need to be aware of.
Gamma Ray Burst (1960s)
It is an extremely powerful electromagnetic radiation and is the brightest ever in the known universe. It believed to be caused when two neutron stars collide, or when a black hole forms from an immensely powerful supernova. It was discovered in the 1960s by satellites orbiting the earth, which are specially designed to pick up signs of any nuclear bomb detonations in space. Gamma Ray Bursts are so powerful that if one were to hit the earth, the ozone layer would be destroyed and earth would be exposed to intense UV radiation from the sun.
The Theory of Relativity (1905)
This theory was proposed by Albert Einstein and it tells us how the universe worked. Previously, Newton’s laws were unable to explain some of the phenomenon and problems that plagued scientists. In other words, the Theory of Relativity effectively replaced Newtonian mechanics. One of the highlights of Albert Einstein’s theory states that time was relative. It told us that very big objects like stars could “bend” space and time around it. An effective analogy is to imagine a heavy ball moving across a trampoline and the depression caused around the ball is the distorted space and time.
