Do Parallel Universes exist?
The term ‘multiverse’ was coined in 1895 by the American philosopher William James. It refers to the idea that the universe is just one of many. Numerous prominent scientists believe that parallel universes exist, including Stephen Hawking. Some scientists have suggested that the ‘Mandela Effect’ is also due to the existence of such parallel universes. However, there is no way to prove their existence, with many scientists arguing that alternate realities are merely speculation. Without any possibility of being able to travel to these potential parallel universes, it is highly unlike that we will find the answer to this question.
What causes Gamma Ray Bursts?
Gamma ray bursts have a reputation as the brightest events in the universe. They release more energy in a matter of seconds than the average star will do during its entire lifetime. These bursts were first recorded in 1967 but, despite thousands being observed since then, no one has ever been able to conclusively verify their source. One of the biggest complications for the study of gamma ray bursts is that they have only ever been recorded in distant galaxies, about which we know very little. Some suggest that they’re caused by gigantic collisions between black holes and neutron stars, but current technology is insufficient to confirm this.
What is Dark Matter?
Approximately 27% of the universe is made of dark matter, yet scientists don’t actually know what it is. This is because dark matter is not directly observable with current instruments as it is completely invisible. However, scientists are certain of its existence because they have observed its gravitational effects on galaxies and galaxy clusters. Scientists are currently conducting experiments hoping to generate and study dark matter particles that could potentially provide the key to this puzzling mystery.
Could Other Planets support life?
With at least 100 to 200 billion planets in the Milky Way alone, there is a strong likelihood that the universe could be home to other planets capable of supporting life. Physicists have already discovered a number of Earth like planets that show potential such as Gliese 581 d. Gliese 581 d is around 204 light years away from Earth in the constellation of Libra and is believed to have liquid water on its surface. With 6.98 times the mass of Earth, it has been classed a ‘Super-Earth’. Since its discovery in 2007, observatories have been unable to conclude whether its composition is suitable to support life.
