The answer is that the expansion of the universe is only noticeable over distances of hundreds of millions of light years or more. Over the much smaller distances found within galaxies and planetary systems its effects are negligible.
The universe is so big and it will never be completely populated because it includes areas that are unlivable. The Earth is part of the whole universe.
The nucleus contains the mass.
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
The part of the universe on which attention is being focused is typically referred to as the "region of interest." This could be a specific area of the sky for astronomers, a particular galaxy cluster, or even a specific object like a black hole or supernova. By focusing on a region of interest, scientists can gather detailed data and insights about that particular part of the universe.
"Does everyone exist or are they just part of the universe that I am creating?" is a question that has been asked in philosophy many times. This varies depending on what you believe. Most people believe that everyone does actually exist.
The answer is that the expansion of the universe is only noticeable over distances of hundreds of millions of light years or more. Over the much smaller distances found within galaxies and planetary systems its effects are negligible.
what are the four part of the universe
Without a Universe, there would be no world, either. "World" can refer to:* The Universe itself * Planet Earth, which is part of the Universe
It is believed that in the far, far future, a large part of the mass that is currently concentrated in galaxies will accumulate in the central black hole.
A galaxy is a tine part of the universe.
they are not part of mass... they are the reason there's mass
There really isn't much to "study" there - there is simply a law that states that mass can't be created or destroyed. As to the "why we need to study...", well, it's a fairly fundamental part of how our Universe works.
Gravity regulates and repairs the universe.
The Universe is everything . So, Aluminium makes up part of the universe: a tiny fraction of it.
Everything in space is part of the universe or cosmos.the universe
Pluto is part of the universe, and so must be smaller.
