Where are we in the universe?
Well, Earth is located in the universe in the Virgo Supercluster of galaxies.
A supercluster is a group of galaxies held together by gravity.
Within this supercluster we are in a smaller group of galaxies called the Local Group.
Earth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way.
What is in the universe?
The Universe is everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty.
How was the universe created?
Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
What is beyond the universe?
So, in some ways, infinity makes sense. But “infinity” means that, beyond the observable universe, you won’t just find more planets and stars and other forms of material…you will eventually find every possible thing.
Is the universe infinite?
Because we cannot observe space beyond the edge of the observable universe, it is unknown whether the size of the Universe in its totality is finite or infinite.
How many Earths are there in the universe?
On November 4, 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarf stars within the Milky Way galaxy.
Who is the creator of universe?
Vishnu is the primary creator.
Is the universe flat?
The global shape of the universe can be described with three attributes: Finite or infinite. Flat (no curvature), open (negative curvature), or closed (positive curvature) Connectivity, how the universe is put together, i.e., simply connected space or multiply connected.
Will the universe end?
Theories about the end of the universe. The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.
What planets are in the Milky Way?
How fast is the universe expanding?
Wendy Freedman determined space to expand at 72 kilometers per second per megaparsec – roughly 3.3 million light years – meaning that for every 3.3 million light years further away from the earth you are, the matter where you are, is moving away from earth 72 kilometers a second faster.
Is dark matter matter?
Dark matter is a form of matter thought to account for approximately 85% of the matter in the universe and about a quarter of its total energy density. Most dark matter is thought to be non-baryonic in nature, possibly being composed of some as-yet undiscovered subatomic particles.
Is there a center of the universe?
The center of the Universe is a concept that lacks a coherent definition in modern astronomy; according to standard cosmological theories on the shape of the universe, it has no center. Historically, different people have suggested various locations as the center of the Universe.
Why we Cannot see beyond the observable universe?
Assuming dark energy remains constant (an unchanging cosmological constant), so that the expansion rate of the universe continues to accelerate, there is a “future visibility limit” beyond which objects will never enter our observable universe at any time in the infinite future, because light emitted by objects outside
What is big crunch theory?
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach zero, an event potentially followed by a reformation of the universe starting with another Big
