From the discovery of steam engines to crusading in space with rocket engines. Humankind has come a long way and embraced civilization. By nature, humans are curious, which has landed us in trouble sometimes, but for most parts, it encourages advancement.
Scientific discoveries (yeah, cool scientific discoveries we mean) are inevitable and perpetual. Every time you think you have found the answer to something, you will be met with ten more questions. It fuels our desire to live and improves our quality of life.
Let’s take a look at a few cool scientific discoveries in the past decade.
You might have stumbled across the term theory of relativity. It is the backbone of every movie that is based on time travel. Albert Einstein hypothesized that if an object with mass accelerates fast enough (assumed speed of light), it can tear through the fabric of time and create ripples in the space-time continuum.
To prove this theory, the concept of gravitational waves was paramount. Einstein retired believing gravitational waves did not exist, but researchers and scientists since then have been looking for this space-time unicorn.
The quest saw results in 2015 when the U.S.-based observatory LIGO felt the aftershock of a distant collision between two black holes. In 2017, LIGO and the European observatory Virgo felt another set of tremors. The collision of neutron stars caused this shock. Telescopes captured this moment, and humanity saw the physical representation of light and gravitational waves.
Water on Mars
We are enamoured by space and the idea of living on another planet. Billionaire geniuses like Elon Musk believe that humans need to be multi-planetary species to survive. Mars has always been the ideal destination among all the planets in the solar system.
According to Elon Musk, Mars is the most suitable planet to inhabit. Planets like Saturn and Jupiter are essentially huge masses of toxic gasses. Mercury and Pluto have extreme climates, with sub-zero and boiling temperatures lasting for weeks. Mars is the most balanced out of all the planet.
In 2015 NASA made Mars the ultimate contender for the race to a second home. The National Aeronautics and Space Administration confirmed that there is evidence proving the existence of liquid water on Mars. NASA’s Mars Reconnaissance Orbiter (MRO) detected hydrated salts.
Launching a rocket into orbit is a tremendously complicated and expensive journey. Just the rocket alone costs millions, and with the added infrastructure and technology needed, the entire operation costs billions.
In an ideal rocket launch, the astronauts would break the atmospheric barrier and return to earth safely, destroying the rocket in the process. The only solution was to create reusable rockets, but that is easier said than done.
Visionary entrepreneurs like Elon Musk dedicated most of SpaceX’s resources to designing and building reusable rockets. After years of failure and millions lost, on April 8 2016, SpaceX made history. They successfully launched Falcon 9 and made a round trip back to the base, safely landing. SpaceX has set the trend for reusable rockets leaving the rest of the world catching up to their engineering marvel.
Only time will tell what else we will uncover. Survival is not just for the fittest anymore; it is for the smartest, and pushing the envelope is the only way forward. But these cool scientific discoveries are surely mind-numbing!
