When does a star's size abuse the laws of physics?

 The size of a star is a characteristic result of the harmony between the internal draw of gravity and the outward weight of radiation delivered inside the star. At the point when these two powers are adjusted, the external layers of the star are steady and supposed to be in hydrostatic balance. All in all, both the gravitational power and the energy age rate are dictated by the mass of a star. During the greater part of their lives, stars consume hydrogen in their centers, and their structures are totally dictated by their masses. Later in the course of their lives, energy is produced in a shell encompassing their centers, and the external layers grow, for example, in the red supergiant (for higher-mass stars) and red goliath (for lower-mass stars) stages. 


Despite the fact that stars don't have surfaces, the most well-known definition for the external limit of a star is the photosphere, or the area where light leaves the star. The greatest stars are red supergiants, and the greatest has a span that is roughly multiple times the range of the Sun (432,300 miles [695,700 km]). The purpose behind this most extreme noticed size not surely knew. 


One may figure that a more monstrous star would develop to be greater in its red supergiant stage, yet more gigantic stars don't advance through a red supergiant stage, and they thus don't develop as huge. Maybe one could envision a star with self-assertively enormous mass and in this way self-assertively huge size, however no stars have been found with masses past roughly 200 to 300 sun oriented masses — even at that mass, they are more modest than the greatest red supergiants. One of the biggest realized stars is the red supergiant VY Canis Majoris, which would wrap Jupiter in the event that it were set at the Sun's area.
