Sun - Wikipedia - At this time in the Sun's life, ... The hydrogen and most of the helium in the Sun would have been produced by Big Bang nucleosynthesis in the first 20 minutes of the universe, and the heavier elements were produced by previous generations of stars before the Sun was formed, and spread into the interstellar medium during the final stages of stellar life and by events such as supernovae. Since ...
Human evolution - Wikipedia - Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes the great apes. This process involved the gradual development of traits such as human bipedalism and language, as well as interbreeding with other hominins, which indicate that human evolution was not linear but a web.
Cosmology & the Big Bang - Curious About Astronomy? Ask an ... - It is a perfect black body with a temperature of 3 Kelvin. Taken with the expansion of the universe, this radiation says that the universe must have been much hotter in the past and also opaque to radiation. It turns out that the CMB radiation fits in perfectly with being from the first photons to escape after the universe became transparent. The universe became transparent for the first time ...
What Existed Before the Big Bang? | HowStuffWorks - It is difficult enough to imagine a time, roughly 13.7 billion years ago, when the entire universe existed as a ng to the Big Bang theory, one of the main contenders vying to explain how the universe came to be, all the matter in the cosmos -- all of space itself -- existed in a form smaller than a subatomic particle [source: Wall].
General relativity - Wikipedia - General relativity, also known as the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or ...
Understanding gravity—warps and ripples in space and time ... - It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects. Image source: T ...
Black Hole Apocalypse | NOVA | PBS - This black hole rotates rapidly, distorting and dragging the fabric of space-time. Like all black holes, the event horizon is completely featureless. Remember, there's nothing there; it's just a ...
Big Bang - Wikipedia - The Big Bang theory is the prevailing cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from an initial state of high density and temperature, and offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic ...
Einstein's Theory of General Relativity: A ... - Space - Albert Einstein determined that massive objects cause a distortion in space-time, which is felt as gravity. This formed the basis of this theory of general relativity.
Dark matter - Wikipedia - the Big Bang theory. Timeline of cosmological theories Category Astronomy portal; Dark matter is believed to be a form of matter thought to account for approximately 85% of the matter in the universe and about 27% of its total mass–energy density or about 2.241 × 10 −27 kg/m 3. Its presence is implied in a variety of astrophysical observations, including gravitational effects that cannot ...
