black hole. His equations suggest such wormholes are viable alternatives to the "space-time singularities" that Albert Einstein predicted to be at the centre of black holes. DIFFERENT THEORIES PROPOSED: According to Einstein’s equations for general relativity‚ singularities are created whenever matter in a given region gets too dense‚ as would happen at the ultra dense heart of a black hole. Einstein’s theory suggests singularities take up no space‚ are infinitely dense‚ and are infinitely hot—a

Newton’s Law of Universal Gravitation Apples had a significant contribution to the discovery of gravitation. The English physicist Isaac Newton (1642-1727) introduced the term "gravity" after he saw an apple falling onto the ground in his garden. "Gravity" is the force of attraction exerted by the earth on an object. The moon orbits around the earth because of gravity too. Newton later proposed that gravity was just a particular case of gravitation. Every mass in the universe attracts every other

The Big Bang theory is the prevailing cosmological model for the early development of the universe.[1] The key idea is that the universe is expanding. Consequently‚ the universe was denser and hotter in the past. Moreover‚ the Big Bang model suggests that at some moment all matter in the universe was contained in a single point‚ which is considered the beginning of the universe. Modern measurements place this moment at approximately 13.8 billion years ago‚ which is thus considered the age of the

Black holes When the word black hole pops to mind our initiative thought is literally a black hole with no end. What is really the definition of a black hole? A black hole is a point in space in which gravity pulls in a drastic matter that not even light can exit. Not even human’s vision is capable of viewing these holes. We only take notice as stars around black holes act differently than other stars in space. We can only ask questions such like; when they were theorized? How big

Albert Einstein was a German-born theoretical physicist. He developed the general theory of relativity‚ one of the two pillars of modern physics. He is best known for his mass–energy equivalence formula E = mc². ACCOMPLISHMENT: Einstein gave the explanation for calculation of Avogadro’s number and the size of molecules. Einstein was

Dark matter is a hypothetical substance that is invisible to the eye and accounts for much of the universe. In fact‚ dark matter makes up 27% of the universe. There is not much information that says directly what dark matter is‚ but instead what dark matter is not. Scientists know that it is not a form of antimatter or normal matter. This is proven by the fact that dark matter does not have interactions with the electromagnetic force like normal matter does. If the dark matter did interact with

standard cosmological model). In steady state views‚ new matter is continuously created as the universe expands‚ so that the perfect cosmological principle is adhered to.Theoretical calculations showed that a static universe was impossible under general relativity‚ and observations by Edwin Hubble had shown that the universe was expanding. The steady state theory asserts that although the universe is expanding‚ it nevertheless does not change its appearance over time (the perfect cosmological principle);

This is in contrast to ordinary quantum field theory‚ which predicts point particles that emit and absorb each other. String theory is a candidate for a Theory of Everything." String theory would solve the long fight between Einstein’s theory of relativity and Quantum Physics. String theory proclaims that everything in our universe‚ from stars and suns to apples and atoms‚ is made up of incredibly small particles called strings. Strings are so small‚ that if an atom were the size of our solar system
