"Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe."
The whole universe is made up of atoms but the exact composition of the black matter (blackHole) is not known
Because hydrogen is the most abundant element in our universe.
There are various concepts and theories about the universe, including the Big Bang theory, multiverse theory, inflation theory, and the cosmic microwave background radiation. These concepts seek to explain the origins, expansion, and composition of the universe.
Lithium is one of the three elements (along with hydrogen and helium) created in the Big Bang, so it is abundant in the universe. It is estimated that lithium makes up about 0.0007% of the universe's elemental composition.
Subatomic particles are responsible for the composition of matter. They allow our universe to be recognizable as we see it today.
A hollow universe would challenge our current understanding of the cosmos by suggesting that there may be empty spaces or voids within the universe. This could impact our theories about the structure and composition of the universe, as well as our understanding of how matter and energy are distributed throughout space. It would require us to reconsider our models of the universe and how it functions.
Stars are important in the study of astronomy and understanding the universe because they are the building blocks of galaxies, they help us understand the life cycle of celestial objects, and they provide valuable information about the composition and evolution of the universe.
Atoms make up most matter around us. In the Universe in general, it seems that atoms make up about 4% of the mass of the Universe. The remainder of the Universe mass is dark matter and dark energy - both of unknown composition.
Each chemical element has a specific emission or absorption spectrum.
Measuring the current density of the universe is important because it helps us understand the distribution and composition of matter in the universe. By studying current density, we can learn about the evolution and structure of the universe, including the role of dark matter and dark energy in shaping its properties. This information is critical for developing accurate models of the universe's past, present, and future behavior.
Chemists study the universe by analyzing the composition of extraterrestrial objects like meteorites and comets. They also use spectroscopy to analyze light from stars and planets to determine their chemical makeup.
