A white dwarf star, as well as any other stable variety of star,
is held together by the pressure popularly known as "gravity".
In the opposite direction, white dwarf stars are kept from collapsing completely by degeneracy pressure. Specifically, for white dwarf stars, it's electron degeneracy pressure, which arises from the fact that electrons are fermions and cannot all occupy the same energy state. For higher mass stars, the force of gravity is able to overcome this and push all the electrons into the ground state, and the star is supported by a different kind of degeneracy ... neutron degeneracy, which is the same thing but with neutrons ... and you get a neutron star. At even higher masses, even that isn't sufficient and the star collapses all the way into a black hole.

What does the equilibruim between the outward pressures of radiaion and the force of gravity do?
While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star.
Are dwarf planets bigger than asteroids?
Yes. The difference is that a dwarf planet must have enough mass to have crushed it into a sphere under the influence of gravity.
What may form as a direct result of the star collapsing?
A direct result of a star collapsing could be the formation of a black hole. This occurs when the core of a massive star collapses under its own gravity, creating a region of space with such strong gravitational pull that not even light can escape.
What shape makes the most stable structure?
Triangles are considered the most stable shape for structures because they distribute weight and forces evenly. The triangular shape is the strongest geometric shape because it has the smallest possibility of warping or collapsing under stress. That's why many buildings and bridges are designed with triangular supports.
What is the average weight of a bunny in kg?
Rabbits come in many different sizes, from dwarf to giant. How much a rabbit weighs depends on its species and breed. A healthy pet rabbit could weigh under 2 kg, or more than 10kg. A vet with experience and knowledge in rabbit care and behaviour could tell you the healthy weight for you rabbit.
What prevents galaxies from collapsing under their own weight?
Their rotation.
What keeps the sun from not falling?
The sun's immense gravitational pull created by its mass keeps it from falling. The gravitational force pulls the sun's gases and radiation inward, creating a balance with the outward pressure caused by nuclear fusion reactions in its core. This balance keeps the sun stable and prevents it from collapsing under its own weight.
What is the purpose of the bridge pillars in supporting the structure of a bridge?
The purpose of bridge pillars is to provide support and distribute the weight of the bridge evenly, helping to prevent the bridge from collapsing under its own weight or the weight of vehicles passing over it.
What does the equilibrium between the outward pressures of radiation and the force of gravity do?
"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."
Why prevents stars collapsing under the force of their own gravity?
The pressure of the fusing gasses
What keeps a star on the main sequence from collapsing?
Nuclear fusion produces heat, and heat creates the pressure which keeps the star from collapsing under its own gravity. The relationship between heat and pressure in a gas is described by the Ideal Gas Laws. It also applies to plasma (which can be described as a super heated gas).
What are the statistics for dwarfism?
A dwarf is a person under 4'10".
How do bridges work to support the weight of vehicles and pedestrians?
Bridges work by distributing the weight of vehicles and pedestrians across their structure, using a combination of materials like steel and concrete to provide strength and support. The design of the bridge, including its arches, beams, and cables, helps to evenly distribute the load and prevent the structure from collapsing under the weight.
How much should a 9 month old dwarf rabbit weigh?
On average, a 9-month-old dwarf rabbit should weigh between 2-4 pounds depending on the specific breed. It's important to monitor their weight regularly to ensure they are healthy and not under or overweight.
What does the equilibruim between the outward pressures of radiaion and the force of gravity do?
While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star.
Is it possible if a 13 year old girl weighs 67 pounds?
yes it is but extremely under weight. really not healthy and if it keeps up might have an eating disease
Why is the trachea so constructed?
It needs to be able to function under the pressure of breathing and head movement without collapsing.
