🚀The universe began with the Big Bang, a massive explosion that created all matter and energy.
⏰Time is not constant throughout the universe and can be affected by gravity and velocity.
⭐️Stars are born from gas and dust clouds, and their life cycle includes the formation of planets.
🌌Galaxies are vast collections of stars, gas, and dust, held together by gravity.
⚫️Black holes are regions of extremely strong gravity where nothing can escape, not even light.
What caused the Big Bang?
—The cause of the Big Bang is still unknown, but scientists believe it was a singularity, a point of infinite density and temperature.
Can anything escape from a black hole?
—Nothing can escape from a black hole, not even light, due to the extremely strong gravity.
How do stars form?
—Stars form from dense clouds of gas and dust called nebulae. Gravity causes these clouds to collapse and form a protostar, which eventually becomes a star.
What happens at the end of a star's life?
—Depending on its mass, a star can end its life as a white dwarf, neutron star, or a black hole.
What is dark matter?
—Dark matter is a mysterious substance that does not interact with light, but its gravity affects the motion of stars and galaxies.
