What happens when the gravity of a massive star is able to overcome neutron degeneracy pressure? The star explodes violently, leaving nothing behind. The core contracts and becomes a white dwarf. The core contracts and becomes a black hole.

Over its lifetime, a low mass star consumes its core hydrogen and converts it into helium. The core shrinks and heats up gradually and the star gradually becomes more luminous. Eventually nuclear fusion exhausts all the hydrogen in the star’s core.

Formation and evolution During the initial collapse, this pre-main-sequence star generates energy through gravitational contraction. Once sufficiently dense, stars begin converting hydrogen into helium and giving off energy through an exothermic nuclear fusion process.

E) As gravity overwhelms the electron degeneracy pressure, it will explode as a supernova. It will cool down and become a cold black dwarf.

25) How does the gravity of an object affect light? A) Light doesn’t have mass; therefore, it is not affected by gravity. Light coming from a compact massive object, such as a neutron star, will be redshifted. C) Light coming from a compact massive object, such as a neutron star, will be blueshifted.

Although the constants of electromagnetism never appear in the equations for Einstein’s General Relativity, the speed of gravity undoubtedly equals the speed of light.

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

In quantum mechanics, fields are discontinuous and are defined by ‘quanta’. Quantum mechanics is incompatible with general relativity because in quantum field theory, forces act locally through the exchange of well-defined quanta.

This equivalence between floating and falling is what Einstein used to develop his theory. In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line.
