Fusion is the process in which several hydrogen nuclei, with a single proton each, combine into a single helium nucleus with two protons and two neutrons. During this process, a tiny bit of the mass is "destroyed" and converted into energy, in accordance with Einstein's famous "e=mc^2" equation. Energy released is equivalent to the mass destroyed, times the speed of light squared. The amount of mass is VERY tiny - but the speed of light is a very large number, and multiplied by itself is an ENORMOUS number. So, a very small amount of mass is converted into a very large amount of energy.
That energy of fusion, expressed as heat, is the process that powers nuclear bombs, and the Sun's fusion is equivalent to millions of nuclear bombs going off all at once, every second. That much explosive power would certainly tend to blow anything apart!
Except, it DOES NOT, generally, blow stars apart, because the power of the nuclear fusion is balanced by the force of gravity; the mass of the star generates gravity, which tries to crush everything in the star down to a tiny point. And so a star is in balance; the power of fusion, contained by the power of gravity.
In some cases, when the large star's energy is boosted suddenly, a star CAN blow itself apart. We all this a "nova", and if it's powerful enough, a "super-nova", and it normally happens to very large stars (more than about 3 times the mass of our Sun) at the ends of their lives.
What else can I help you with?
How do gravity and fusion have opposite effects on a star?
Gravity acts to pull matter inward, causing a star to contract and increase density. Fusion, on the other hand, generates energy by fusing hydrogen nuclei to form helium, resulting in outward pressure that counteracts gravity and maintains the star's stability.
How do gravity and fusion of have opposite effect on a star?
Gravity and fusion have opposing effects on a star by influencing its stability and lifecycle. Gravity pulls matter inward, creating pressure and heat at the core, while fusion generates energy that exerts an outward pressure due to the release of radiation. In a stable star, these forces are balanced; however, if fusion slows, gravity can cause the star to collapse, leading to potential changes in its structure or even a supernova. Conversely, if fusion increases, it can counteract gravitational forces, allowing the star to expand and evolve into different stages of stellar life.
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
How does gravity affect our lives?
Without gravity we would HAVE NO LIVES. For instance, gravity keeps our Earth together; and gravity is an important component in making the Sun produce energy via nuclear fusion.
What effect does gravity have on the core of the star?
Gravity plays a crucial role in the core of a star by compressing its material, which leads to high temperatures and pressures necessary for nuclear fusion. This gravitational force counterbalances the outward pressure generated by the energy produced during fusion reactions. As a result, gravity helps maintain the star's stability and structure throughout its lifecycle. Without gravity, the core would not be able to sustain the fusion processes that power the star.

What is the force opisit of gravity?
The opposite force of gravity is the electromagnetic force. This force is responsible for interactions between charged particles such as electrons and protons, and it can either attract or repel these particles depending on their charges.
How do fusion and gravity maintain stars in their current form?
Fusion pushes out, Gravity pulls in.
Can you explain the differences between nuclear fusion and gravity in terms of their roles in the formation and behavior of celestial bodies?
Nuclear fusion and gravity are two key forces in the formation and behavior of celestial bodies. Nuclear fusion is the process where atomic nuclei combine to release energy, which powers stars like the Sun. Gravity, on the other hand, is the force that pulls matter together, causing it to clump and form celestial bodies like planets and stars. While nuclear fusion powers the energy output of stars, gravity is responsible for holding these celestial bodies together and shaping their orbits and interactions. In summary, nuclear fusion fuels the energy of stars, while gravity shapes the structure and behavior of celestial bodies.
What is the opposite reaction to fusion?
fission

Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
What force opposes nuclear fusion in the sun?
The force that opposes nuclear fusion in the sun is gravity. Gravity is constantly pulling inward, trying to compress the sun's material into a smaller space. The outward pressure from nuclear fusion counteracts this force, creating a delicate balance that maintains the sun's stability.
Why am I so bruised after spinal fusion?
Bruises are one of the after effects of spinal fusion.
Can you use De-Fusion on card effects?
"De-Fusion" can only be used on Fusion-type Monsters. No exceptions.
Why does the core collapse once fusion stops?
The energy released by fusion in the core of a star produces an outward pressured force that counteracts gravity. When fusion stops, that force goes away and gravity takes hold, causing the core to collapse.
What process release the most energy from nuclear fusion burning or shrinking due to gravity?
In a star a balance exist between gravity shrinking and expansion due to fusion energy released.
