Q: What is the definition of the universe?
A: The universe is everything that exists including all physical matter and energy, the planets, stars, galaxies, and all the contents of intergalactic space, encompassing the entirety of space and time.
Q: What does the universe contain?
A: The universe contains billions of galaxies, each filled with stars and their orbiting planets, gas, dust, and dark matter. It also holds the milky way galaxy as part of the content of the universe.
Q: Is the universe expanding or shrinking?
A: Scientific findings suggest that the universe is expanding at an accelerating rate, not shrinking. This is based on many observed phenomena and the theory of general relativity.
Q: What is the size of the universe?
A: Determining the exact size of the universe is challenging due to its constant expansion. However, the observable universe is estimated to be around 93 billion light-years in diameter.
Q: How old is the universe?
A: The age of the universe is estimated to be approximately 13.8 billion years old, given current measurements of the rate of its expansion and model of the universe.
Q: What is the part of the universe that we are in?
A: We are in the Milky Way Galaxy, located in a galaxy cluster. It is a tiny fraction of the entire universe.
Q: How did the universe form?
A: Most scientists believe that the universe was born from the ‘big bang’, an incomprehensibly hot and dense point nearly 13.8 billion years ago. This event caused the universe to start expanding.
Q: Is there a center of the Universe?
A: According to the standard theories of cosmology, the universe started with a “Big Bang” about 14 billion years ago and has been expanding ever since. Yet there is no centre to the expansion; it is the same everywhere. The Big Bang should not be visualized as an ordinary explosion. The universe is not expanding out from a centre into space; rather, the whole universe is expanding and it is doing so equally at all places, as far as we can tell.
Q: What will happen to the universe in the future?
A: Scientists speculate different scenarios for the universe’s future depending on its continued expansion. Many possible futures are based on the present measurable rate at which the universe is expanding.
Q: Are there multiple universes?
A: The concept of multiple universes, or a multiverse, is a speculative theory suggesting the existence of numerous universes in addition to our own. However, empirical evidence to support this theory is currently lacking.
