Physics of the Universe: Difficult Topics Made Understandable
Physics of the Universe: Difficult Topics Made Understandable. The answer to the Ultimate Question of Life, the Universe, and Everything, according to Douglas Adams’ excellent book, is 42. The reality, it turns out, is not quite so simple. Questions about what the universe is, how it began, how it works, and where it is going have exercised ...
Physics Terms
There are four basic forces of physics that are believed to underlie all phenomena in the universe. Listed in order of strength they are: the strong nuclear force , the electromagnetic force , the weak nuclear force and the gravitational force (or gravity ).
Main Topics - Physics of the Universe
I have presented the Main Topics under the following general headings: The Big Bang and the Big Crunch. Special and General Relativity. Black Holes and Wormholes. Quantum Theory and the Uncertainty Principle. The Beginnings of Life.
Quantum Theory and the Uncertainty Principle - Physics of the …
Quantum theory (otherwise known as quantum physics or quantum mechanics) is one of the two main planks of modern physics, along with general relativity, and between them the two theories claim to explain virtually everything about the universe.
Cosmological Theories Through History - Physics of the Universe
Inflationary (or Inflating) Universe - In 1980, the American physicist Alan Guth proposed a model of the universe based on the Big Bang, but incorporating a short, early period of exponential cosmic inflation in order to solve the horizon and flatness problems of …
Big Bang Timeline - Physics of the Universe
Big Bang Timeline. Since the Big Bang, 13.7 billion years ago, the universe has passed through many different phases or epochs. Due to the extreme conditions and the violence of its very early stages, it arguably saw more activity and change during the first second than in …
The Expanding Universe and Hubble's Law - Physics of the Universe
Hubble showed that, in our expanding universe, every galaxy is rushing away from us with a speed which is in direct proportion to its distance, known as Hubble’s Law, so that a galaxy that is twice as far away as another is receding twice as fast, one ten times as far away if receding ten times as fast, etc.
Important Dates and Discoveries - Physics of the Universe
A brief chronological listing of some of the most important discoveries in cosmology, astronomy, and physics, from ancient Babylon, India and Greece, right up to the 20th Century.
Black Holes and Wormholes - Physics of the Universe
Wormholes. Like black holes, wormholes arise as valid solutions to the equations of Albert Einstein 's General Theory of Relativity, and, like black holes, the phrase was coined (in 1957) by the American physicist John Wheeler.
Albert Einstein - Important Scientists - Physics of the Universe
Albert Einstein was a German-born theoretical physicist, best known for his Special and General Theory of Relativity and the concept of mass-energy equivalence expressed by the famous equation, E = mc2. He received the Nobel Prize in Physics in 1921 “for his services to theoretical physics, and especially for his discovery of the law of the ...
