🌌The universe is made up of billions of galaxies, each containing billions of stars.
⚛️Atoms are the building blocks of all matter, and they contain even smaller particles called subatomic particles.
🔭Telescopes allow us to observe objects in the distant universe and gather information about their composition, movement, and history.
🪐Planets are formed from the dust and gas in a rotating disk around a young star.
🕒The age of the universe is estimated to be approximately 13.8 billion years.
What is dark matter?
—Dark matter is a mysterious substance that makes up about 27% of the universe. It does not emit, absorb, or reflect light, and its presence is inferred through its gravitational effects on visible matter.
What is the Big Bang?
—The Big Bang is a cosmological model that describes the beginning of the universe. It proposes that the universe was initially extremely hot and dense, and has been expanding and cooling since its inception.
Are there other universes?
—The idea of multiple universes, known as the multiverse theory, is a topic of speculation in theoretical physics. While there is no direct evidence for the existence of other universes, some cosmological models suggest that they could exist.
How do black holes form?
—Black holes form when massive stars collapse under their own gravity. The intense gravitational force becomes so strong that nothing, not even light, can escape its gravitational pull.
What is the shape of the universe?
—The shape of the universe is still a topic of debate among scientists. Current observations suggest that the universe is flat, meaning it has no curvature, but further research is needed to confirm this.
