Is the universe a closed system?

In summary, A closed system is one that does not exchange matter or energy with its surroundings, while an open system does. The question of whether the universe is a closed or open system is still debated, with evidence supporting both ideas. This debate is important for our understanding of the laws of physics and the future of the universe.

Would the conservation of mass apply to the universe? Sorry I looked for awhile for the answer to this question but I couldn't really find anything.

Conservation of "mass" isn't a law. Conservation of energy is, and mass is a type of energy that is often (but not always conserved).

Conservation of energy does apply to the whole universe.

It appears you are asking if the universe is a closed system. That is uncertain. It appears, however, that mass/energy is conserved in either case.
 

What is a closed system?

A closed system is a physical system that does not exchange matter or energy with its surroundings. This means that the total amount of matter and energy within the system remains constant.

Is the universe considered a closed system?

The question of whether the universe is a closed system is still a subject of debate among scientists. Some theories suggest that the universe is a closed system, while others propose that it is an open system that is constantly expanding and exchanging energy with its surroundings.

What evidence supports the idea that the universe is a closed system?

One of the main pieces of evidence for a closed universe is the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed. This suggests that the total amount of energy in the universe must remain constant, supporting the idea of a closed system.

What evidence supports the idea that the universe is an open system?

The expansion of the universe is one of the main pieces of evidence for an open system. The theory of the Big Bang suggests that the universe began as a singularity and has been expanding ever since, which would require the universe to be an open system that is constantly exchanging energy with its surroundings.

Why is the debate about the universe being a closed or open system important?

The debate about the nature of the universe has important implications for our understanding of the laws of physics and the future of the universe. If the universe is a closed system, it means that the laws of physics will remain constant and the universe will eventually reach a state of equilibrium. If it is an open system, it suggests that the universe will continue to expand and change in unpredictable ways.
