Is gravity stronger than entropy?
Gravity tries to keep things together through attraction and thus tends to lower statistical entropy.
What is gravitational theory?
A theory of gravitation is a description of the long range forces that electrically neutral bodies exert on one another because of their matter content. Best known of these is Albert Einstein’s general theory of relativity, which reduces to Newton’s theory in a certain limit. …
What was Einstein’s idea of gravity?
Einstein argued that gravity isn’t a force at all. He described it as a curvature of time and space caused by mass and energy. Confused? The German physicist was, too, and he struggled with the theory for nearly a decade.
How was gravitational force discovered?
Legend has it that Isaac Newton came up with gravitational theory in 1665, or 1666, after watching an apple fall. “He showed that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits,” Martin Rees says.
What is Erik Verlinde’s theory of gravity?
Erik Verlinde’s theory. In 2009, Erik Verlinde proposed a conceptual model that describes gravity as an entropic force. He argues (similar to Jacobson’s result) that gravity is a consequence of the “information associated with the positions of material bodies”. This model combines the thermodynamic approach to gravity with Gerard ‘t Hooft ‘s…
Is the lensing effect of gravitational fields consistent with Verlinde’s theory?
A team from Leiden Observatory statistically observing the lensing effect of gravitational fields at large distances from the centers of more than 33,000 galaxies, found that those gravitational fields were consistent with Verlinde’s theory.
Can a new gravitational theory just do away with dark matter?
A new gravitational theory formulated by Erik Verlinde, renowned string theory expert at the University of Amsterdam and the Delta Institute for Theoretical Physics, might just do away with the roles of dark matter and dark energy in explaining the physics of the universe.
Does our theory of gravity need to be updated?
While that theory can explain a lot of the behavior of our universe, it doesn’t hold up when applied to quantum physics, which becomes evident in extreme situations like near a black hole or during the Big Bang. Therefore, Verlinde and many other physicists think that our theory of gravity needs to be updated.
