TOI-700 D: An Earth-Size Exoplanet In Its Star’s “Goldilocks” Zone
In January 2020 the first planet to be found by NASA’s Transiting Exoplanet Survey Satellite (TESS) was a distant Earth-size planet, comfortably located in its star’s habitable zone The habitable zone of a star is that “Goldilocks” range of distances where conditions are not too hot, not too cold, but “just right” for liquid water to pool on the surface. Where liquid water exists, life as we know it may also exist.
Infinite Space As an Alternative to the Singularity
Is the Big Bang correct? What is the early universe could have been comprised of nothing but dark matter? There was no free energy, no nothing, not even gravity because, since nothing existed there was nothing to experience gravity.
Uranus And Neptune: Two Different Worlds
Although the two planets should be almost identical twins, they are not. In February 2020, a team of planetary scientists from the University of Zurich in Bern, Switzerland, told the press that they believe they have discovered why.
A Cheat Sheet In The Search For Exoplanet Life
Are we alone? The elusive answer to that profound question may be coming soon as astronomers search for the holy grail of signs of life on worlds that circle stars beyond our Sun.
The Mysterious Moons Of Mars
Mars is a true Wonderland world that has sung its enticing Sirens’ song for centuries to those who seek to solve its many mysteries. Indeed, the two moons of Mars, named Phobos and Deimos, present some mesmerizing mysteries all their own. Where did the two moons of Mars come from?
The Mystery Of The Missing Magnetic Monopoles
One of the best-kept secrets of the Cosmos involves a weird hypothetical elementary particle called a magnetic monopole. According to theory, these exotic magnetic monopoles should exist somewhere in the Universe–and yet not one solitary magnetic monopole has ever been found.
What Is Randomness?
What is meant by randomness? Random processes are very important in lots of areas of maths, science and life in general, but truly random processes are remarkably difficult to achieve.
Much More is Unknown About our Universe than What is Known
We live in a mysterious Universe – most of which we are unable to see – and its current rate of expansion is believed to be caused by a bizarre substance called Dark Energy. Dark Energy is generally considered to be a property of Space itself, and it first emerged in Albert Einstein’s calculations that formed his Theory of General Relativity.
The Simulation Hypothesis: More Evidence From Physics And Astronomy
The Simulation Hypothesis states that there is a high probability that what we call life, the Universe and everything exists as a state of virtual reality within a higher realm of really real reality. We are a computer simulation ‘living’ in a virtual landscape. There are various observations in the physical sciences that are suggestive that this hypothesis is true
