Physics Galaxy was founded as an online learning portal by Ashish Arora. [2] It was founded as an initiative to coach students for free especially for those in rural areas, who cannot afford expensive coaching facilities. Later in 2011, a YouTube channel of the same name was founded. [3] [4]
An N-body simulation of the cosmological formation of a cluster of galaxies in an expanding universe. In physics and astronomy, an N-body simulation is a simulation of a dynamical system of particles, usually under the influence of physical forces, such as gravity (see n-body problem for other applications).
In physics, specifically classical mechanics, the three-body problem is to take the initial positions and velocities (or momenta) of three point masses that orbit each other in space and calculate their subsequent trajectories using Newton's laws of motion and Newton's law of universal gravitation.

NGC 2207 (the bigger galaxy to the left) and IC 2163 (the smaller galaxy to the right) as seen by the Hubble Space Telescope. Galaxies form in various ways. In most Cosmological ''N''-body simulations, the earliest galaxies in the cosmos formed in the first hundreds of millions of years. [7]
If the autocorrelation function describes the probability of a galaxy at a distance from another galaxy, the matter power spectrum decomposes this probability into characteristic lengths, /, and its amplitude describes the degree to which each characteristic length contributes to the total over-probability.
Modified Newtonian dynamics (MOND) is a theory that proposes a modification of Newton's second law to account for observed properties of galaxies.Its primary motivation is to explain galaxy rotation curves without invoking dark matter, and is one of the most well-known theories of this class.
Published by Hudson Soft, Crayon Physics Deluxe was released for the iOS on January 1, 2009 and in Spring 2010 for the iPhone via Apple's App Store. [7] A version for the PC was released six days later. [8] An unofficial clone was made for the DS, but only in free play mode and under the title of Pocket Physics. [9]
