The Big Bang Theory. In his studies, Hubble concluded that objects were moving away from the Earth – something which today is called the Hubble Constant. Celestial objects are moving away from us, and above this, they are doing so faster than the speed of light, which should be theoretically impossible. This is the basis of the Big Bang ...
Key to the idea of the Big Bang is an understanding that the universe is gradually expanding. In 1912 observations by Vesto M. Slipher indicated redshifting of the light from remote galaxies. This led to the theory that the galaxies may be receding from the earth or basically moving further away. A decade later using Einstein’s field ...
October 17, 2019. Here is a brief outline of the current theory of the events in the early history of the solar system: A cloud of interstellar gas and/or dust (the “solar nebula”) is disturbed and collapses under its own gravity. The disturbance could be, for example, the shock wave from a nearby supernova. As the cloud collapses, it heats ...
Well the Big Bang is a theoretical event that exists in physics which describes a possible version of our universe expanding from an initial state of high density and temperature. The work of mathematicians and astronomers has combined for decades in trying to prove or disprove this theory based on our observable universe. The Outward Expansion ...
But just how big is the Earth? The Earth has a radius of 2.439 kilometers / 1.516 miles and a diameter of only 12.742 km / 7.917 mi. When it comes to weight, the mass of Earth is equivalent to 5.9 quadrillion kg. In the Solar System, our Earth is the fifth largest planet and the largest of the terrestrial planets.

The oldest and farthest galaxy ever discovered is an irregular type of galaxy called GN-z11. It is 32 billion light-years / 9.8 billion parsecs away from us. It is estimated that the galaxy formed just around 400 million years after the Big Bang. Most galaxies are between 1.000 to 100.000 parsecs / 3.000 to 300.000 light-years in diameter.
January 4, 2021. The phrase falling stars, or shooting stars as they are called in different regions, describes meteors or other pieces of matter that burn up and disintegrate as they hit the Earth’s surface and pass through it. It is important to understand the difference between the term meteor and meteorite.
The Earth is estimated to be 4.54 billion years old, so the Universe itself is, on average, around three times older than our Earth but only if the Universe is indeed 13.8 billion years old. Our galaxy, the Milky Way, might be a better comparison, as it is 13.51 billion years old.
