A galaxy contains billions of stars. A universe contains billions of galaxies.
simply,the difference is that earth is a planet in the solar system and the universe is the entire infinite space containing the solar system,stars, asteroids ,black holes and all that space has to offer.
there is no difference. they are both 42.
The Universe is everything, as far as we know. A galaxy is just a collection of stars. A galaxy is huge - typically about 100,000 light-years across - but the visible Universe contains hundreds of billions of galaxies.
Like our galaxy contains billions of stars, the universe contains billions of galaxies.
Without the difference between scalars and vectors the Universe doesn't work !
The Universe is much larger, and contains many solar systems.
The collection of all galaxies and the space between them is known as the universe. The universe is vast and contains everything that exists, including stars, planets, and dark matter.
Gravity is the force that is present between all objects in the universe. It is responsible for the attraction between objects with mass, such as planets, stars, and galaxies.
There is no difference. It is just different names.
The sky refers to the atmosphere above the Earth where clouds, the sun, moon, stars, and other celestial objects are visible. The universe, on the other hand, encompasses all matter, energy, space, and time, including galaxies, stars, planets, and all cosmic structures. The sky is a small part of the universe that we can observe from Earth.
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
The universe is not black. The universe as a whole is microwave, at a cavity radiation temperature of about 3 K. The space between stars just looks black because you can't see microwave.
