Does Gravity Affect Light? What Are Black Holes?

Improved Essays
In order to find the answer to this question, it must be broken down. What are photons? How does gravity affect light? What is a black hole?

A photon is typically seen as a particle or wave representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. Photons are currently best explained by quantum mechanics. However, it is important to know that photons have both the qualities of waves and particles which is known as wave-particle duality. As Einstein once said in attempt to explain wave-particle duality, "It seems as though we must use sometimes the one theory and sometimes the other, while at times we may use either. We are faced with a new kind

He managed to show that the speed of light within a vacuum is the same no matter the speed at which an observer travels. As a result of his research efforts, he found that space and time were interconnected into a single continuum known as space-time. As he continued to work out this theory, Einstein found that massive objects could cause distortion in space-time. Such objects would be planets, stars, or even black holes. General Relativity also states that it is not mass so much as energy that gravitates. This is why a massless thing such as a photon is affected by …show more content…
This strong gravitational pull occurs because matter has been compressed into into a tiny space. This kind of compression can take place at the end of a star's life. Black holes are invisible, however there are ways that scientists can detect them with specially designed instruments and telescopes. Because black holes pull surrounding light inwards due to their strong gravitational force, scientists cannot actually see black holes, but they can observe the effects of black holes on surrounding stars and gasses using equipment like the Fermi Gamma-ray Space Telescope (NASA 2014). Black holes have something called the event horizon which is the point inside the black hole where the gravitational pull becomes so strong that the escape velocity (the speed at which something would have to go to escape the gravitational field caused by the black hole) is equal to the speed of light. Einstein's Theory of Relativity states that no object can exceed the speed of light, thus, absolutely nothing can escape black holes once it is inside this distance from the center of the black hole. The light moving toward the event horizon “...becomes dimmer millisecond by millisecond, and in less than a second is too dark to see . . . [The light,] like the Cheshire cat, fades from view. One leaves behind only its grin, the other, only its gravitational attraction. Gravitational

    The black hole paradox is an observational phenomenon that results from the combination of quantum mechanics and general relativity which suggests that physical information could permanently disappear in a black hole, allowing many physical states to devolve into the same state. Albert Einstein first predicted black holes in 1916 with the theory of relativity. The term “black hole” was coined in 1967 by John Wheeler and the first black hole was discovered in 1971. There are 3 types of black holes which are stellar black holes, supermassive black holes, and intermediate black holes. Black holes are some of the strangest and most fascinating objects found in outer space.…

    The decades surrounding the quantum revolution in science have been chronicled countless times. Among the ranks of noted histories, Uncertainty by David Lindley brings a unique perspective of a classic tale. The turbulent period in science marked the evolution from absolute determinism to probabilistic interactions. After this era, entropy did not always increase, only sometimes. By following the introduction of Heisenberg’s famous uncertainty principle, Lindley represents the giants of physics as personable characters, each with their own virtues and misgivings; as human as the rest of us.…

    The Decline of Deutsche Physik Contextual Analysis of the Exodus of German Physicists in the Early Twentieth Century “So we see that we cannot attach any absolute signification to the concept of simultaneity, but that two events which, viewed from a system of co-ordinates, are simultaneous, can no longer be looked upon as simultaneous events when envisaged from a system which is in motion relatively to that system” In 1905 German physicist Albert Einstein published the first paper of a new age of Physics. His theory of special relativity, followed by general relativity and the Einstein Field Equations in 1915, and the Copenhagen interpretation of quantum mechanics in 1925 combined to form a more significant shift in natural philosophy…

Not only does my fear of what I don't know going on below my feet in the ocean scare the crap out of me, but that big star filled sky does as well. It doesn't just scare me, but it probably scares and excites scientists studying it all over the world.

    In order to understand and visualise the effect of gravity on time predicted by Einstein's Theory of General Relativity, imagine a large piece of fabric suspended at each end and raised. This represents an area of Einstein's idea of space-time. Now place a spherical object on the fabric; this represents a planet. See how the fabric dips into the ball. You could roll a marble around the edge of the fabric and see that it spirals inwards towards the larger mass; in a way very similar to how a planet pulls at rocks in outer space.…

    It was discovered in 1916 that the general theory of relativity predicts the existence of gravitational waves. “Gravitational waves are perturbations in the curvature of spacetime propagating with the velocity of light. They are caused by accelerating masses. ”2 In order to understand the concept of a gravitational wave it is helpful to understand gravity as explained by the general theory of relativity.…

    A wave is a disturbance of energy. Sound and light are both disturbances in energy, and they both travel in the forms of waves. While sound travels in a longitudinal wave, light travels through a transverse wave. From a perspective of a human, sound and light on earth is very different compared to sound and light in space. These waves have differences in speed, form, shape, and other properties.…

    New possibilities opened up in 1915, when Einstein formulated his famous theory that describes the nature of space, time, and gravity. This theory allows for expansion the fabric of space. In 1917, astronomer Willem De Sitter applied this theory and showed that the universe could be expanding. This was revolutionary because accepted view at the time was that the universe was static in size. Also the universe was considered infinite at one point in time but the Big Bang proved that the universe had to have a history and a beginning.…
