Does the universe have an end?
As the energy density, scale factor and expansion rate become infinite the universe ends as what is effectively a singularity..
Where is the real center of the universe?
There is no centre of the universe! According to the standard theories of cosmology, the universe started with a “Big Bang” about 14 thousand million years ago and has been expanding ever since. Yet there is no centre to the expansion; it is the same everywhere.
What lies at the center of the Milky Way galaxy?
At its center, surrounded by 200-400 billion stars and undetectable to the human eye and by direct measurements, lies a supermassive black hole called Sagittarius A*, or Sgr A* for short. The Milky Way has the shape of a spiral and rotates around its center, with long curling arms surrounding a slightly bulging disk.
How many Milky Ways are in the universe?
It is estimated to contain 100–400 billion stars and at least that number of planets.

How many planets are there in the Universe 2020?
As of 1 August 2020, 4,301 known extrasolar planets in 3,176 planetary systems (including 703 multiple planetary systems), ranging in size from just above the size of the Moon to gas giants about twice as large as Jupiter have been discovered, out of which more than 100 planets are the same size as Earth, nine of which …
Is there a center of universe?
Space itself is curved, so as the universe expands from the Big Bang, it is somewhat like the two-dimensional space on a balloon. But just like the surface of that balloon, there is no center in the universe.
How close is the Milky Way to the Center of the Universe?
The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.
Where is the Milky Way in the universe?
The Milky Way is a spiral galaxy comprised of a bar-shaped core region surrounded by a flat disk of gas, dust and stars about 120,000 light-years wide. Our solar system is located about 27,000 light-years from the galactic center within one of the disk’s four spiral arms.
What part of the Milky Way can we see?
Late on a summer night, the part of the Milky Way Galaxy we can see from Earth stretches high across the sky. The center of our galaxy lies in the direction of the constellation Sagittarius (near the trees, left).
What lies at the center of the universe?
In the 4th century BCE Greece, philosophers developed the geocentric model, based on astronomical observation; this model proposed that the center of the Universe lies at the center of a spherical, stationary Earth, around which the Sun, Moon, planets, and stars rotate.
Is Tulsa really the center of the universe?
TULSA – It is one of Tulsa’s most fascinating and well-known phenomenon: The Center of the Universe. The Center of The Universe is tucked away in downtown Tulsa, and it is a landmark that attracts nearly 10 thousand visitors from across the country throughout the year.
What is outside the universe?
Encountering the Unknown Despite its strangeness, this first idea is one of the easiest to digest. Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.
