25 Scientific Discoveries of the 21st century that Changed The World

Water has been detected on the surface of Mars by various spacecraft over the years.

The first definitive detection of water on Mars was made by the Mars Odyssey spacecraft, which arrived on the planet in 2001.

Since then, other spacecraft and rovers have also found evidence of water on Mars, including the Mars Reconnaissance Orbiter and the Mars Curiosity rover.

Most of the water on Mars is found in the form of ice, either as ice caps at the poles or as underground ice deposits.

There is also evidence that liquid water may exist below the surface of Mars in some areas, but this has not been confirmed.

The identification of several new species of animals and plants, including the world’s smallest vertebrate (the Paedophryne amauensis frog) and the world’s largest dinosaur (the Argentinosaurus).

The first gravitational waves were detected by the LIGO experiment in 2015.

The discovery of gravitational waves has confirmed a key prediction of Einstein’s theory of general relativity.

The Kepler Space Telescope was launched in 2009, discovering thousands of exoplanets and helping to understand the prevalence of habitable worlds in the universe.

Exoplanets are planets outside of our solar system.

In 2008, the Fermi Gamma-ray Space Telescope was launched, giving scientists a new window into the universe at high energies.

The Fermi Gamma-ray Space Telescope (FGST), formerly known as the Gamma-ray Large Area Space Telescope (GLAST), is a space telescope designed to study gamma-ray emissions from celestial sources, including pulsars, black holes, and supernovae.

It was launched into orbit in 2008 and is still operational today. The telescope is named after the Italian physicist Enrico Fermi.

In 2003, the first human case of H5N1 avian influenza, or bird flu, was reported.

This highlighted the need for continued vigilance against emerging infectious diseases.

Bird flu is a viral infection that can affect birds and, in rare cases, also infect humans.

The most common strain of bird flu is H5N1, which is highly contagious among birds and can be deadly. 

Symptoms in birds include fever, respiratory distress, and decreased appetite.

Symptoms in humans can include fever, cough, and difficulty breathing.

It is important to practice good hygiene and avoid contact with infected birds to prevent the spread of bird flu.

The first quantum computer was built in the early 21st century, paving the way for new advances in computing.

The development of quantum computers has the potential to revolutionize computing and information processing.

New technologies for storing and transmitting information, such as quantum computing and optical fibers, have advanced computing in the 21st century.

In 2018, the first image of a black hole was captured using the Event Horizon Telescope.

A black hole is a region of spacetime from which nothing, not even light, can escape.

It is the result of the warping of spacetime caused by a very massive object, such as a star.

The boundary of the region from which no escape is possible is called the event horizon.

When an object gets too close to a black hole, it gets pulled in by the black hole’s immense gravity and can’t escape.

Dark matter is a hypothetical type of matter.

It is called “dark” because it does not interact with light in any noticeable way, making it difficult to detect.

Scientists believe that dark matter exists because of the gravitational effects it has on visible matter, but the exact nature of dark matter remains a mystery.

In 2009, the first confirmed detection of dark matter was made using the Bullet Cluster.

The discovery of dark energy and dark matter has added to our understanding of the composition and evolution of the universe.

With the identification of the first direct evidence of dark matter in 2016, scientists can now confirm that dark matter makes up about 85% of the matter in the universe.

In 2006, the dwarf planet Eris was discovered, leading to the reclassification of Pluto as a dwarf planet.

Eris is a dwarf planet that is in the outer reaches of the solar system.

It was discovered in 2005 and is named after the Greek goddess of discord and strife. Eris is about the same size as Pluto and is one of the largest known dwarf planets in the solar system. 

It is known for its highly elongated orbit, which takes it much farther from the Sun than any other known dwarf planet.

The Rosetta mission was a space mission launched by the European Space Agency (ESA) in 2004 to study the comet 67P/Churyumov-Gerasimenko.

The mission’s goal was to gain a better understanding of comets, which are considered to be some of the oldest and most primitive objects in the solar system.

The mission ended in 2016 when the Rosetta spacecraft was intentionally made to crash into the comet’s surface.

The discovery of new forms of matter, such as Bose-Einstein condensates (ultracold clouds of atoms that behave like a single entity) and time crystals (structures that have periodic motion even at absolute zero temperature).

Bose-Einstein condensates (BECs) are a state of matter.

This wave function can be used to predict the behavior of the bosons, much like how the wave function of an electron can be used to predict the behavior of an atom.

The identification of new mechanisms for controlling and manipulating the behavior of individual atoms and molecules, including the use of lasers to cool and trap atoms.

The exoplanet Kepler-186f was discovered in 2014, and it is the first earth-sized planet found in the habitable zone of its star.

Liquid water could potentially exist on Kepler-186f.

The Earth-like exoplanet Proxima b was discovered in 2016. 

The discovery of exoplanets has expanded our understanding of the diversity of planetary systems in the universe.

The development of new materials with unique properties, such as graphene.

It’s a two-dimensional form of carbon with incredibly strong and conductive properties and metamaterials. 

Metamaterials are artificial materials with properties not found in nature.

Graphene is a material made of a single layer of carbon atoms that has many unique properties, such as high electrical conductivity and strength.

The development of new cancer treatments, such as immunotherapy.

These incredible discoveries have improved survival rates and quality of life for cancer patients.

Also, the identification of new antibiotics and other drugs to treat diseases.

This includes the development of drugs that target specific genes and proteins in cancer cells.

In the past 100 years, we’ve made incredible strides in unlocking the mysteries of consciousness.

We now have a deeper understanding of how our brain creates an incredibly unique and powerful experience – one that can still surprise us!

The identification of the cause of the 1918 influenza pandemic has improved our ability to prevent and control future pandemics.

The 1918 flu, also known as the 1918 influenza pandemic, was a global pandemic of influenza that caused a high number of deaths.

It is believed to have been caused by an H1N1 virus, and it is estimated to have killed tens of millions of people worldwide. 

The flu spread rapidly, and it is thought to have been especially deadly because many people were weakened by World War I.

The harsh conditions of the time did not help. The pandemic ultimately ended in 1919, but its effects were felt for many years afterward.

In the 21st century, we’ve seen sustainable energy take off like never before.

Exciting advancements in renewable tech have opened up a world of possibilities – from innovative solar panels to modern wind turbines and much more!

The development of new surgical techniques, such as minimally invasive surgeries and robotic surgeries, has improved patient outcomes and reduced recovery times.

There are several treatments available for HIV that can suppress the virus and help prevent it from progressing to AIDS.

These treatments are highly effective, and they have helped many people with HIV live long and healthy lives. 

However, there is currently no cure for HIV, and people with the virus will need to continue with their treatment for life.
