NASA estimates 1 billion 'Earths' in our galaxy alone. There are a billion Earths in this galaxy, roughly speaking.
The intersection of the two axii is where Earth is located. We are at the center of the universe. In 2005, data from the Sloan Digital Sky Survey showed us that galaxies are arranged in concentric spheres with Earth and the Milky Way galaxy at the center. Centrifugal force keeps the sun from crashing into the Earth.

Mexico. Teotihuacan in modern-day Mexico – considered the center of the universe by many Mesoamerican tribes, including the Aztecs, and was a model city for the later indigenous civilizations. It was called the "birthplace of the gods" and heavily influenced the region despite being abandoned for centuries.
We live on a planet called Earth that is part of our solar system. But where is our solar system? It's a small part of the Milky Way Galaxy.
The shape of the entire universe can be described with three attributes: Finite or infinite. Flat (zero curvature), open (negative curvature), or closed (positive curvature) Connectivity, how the universe is put together, i.e., simply connected space or multiply connected.
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.
Scientists have previously conducted many tests of whether the universe is the same in all directions. The results gave the researchers apparent expansion speeds across the whole sky – revealing that the universe appears to be moving away from us faster in some directions than others.
The image, the first-ever of a black hole, is destined for the shortlist of iconic images not only for what it can tell astronomers and physicists about how gravity and general relativity work under the most extreme conditions, but also because it captures what EHT Director Sheperd Doeleman called “a one-way door from
But no object is actually moving through the Universe faster than the speed of light. The Universe is expanding, but the expansion doesn't have a speed; it has a speed-per-unit-distance, which is equivalent to a frequency, or an inverse time. Approximately 13.8 billion years: the age of the Universe.
Every point in the universe is expanding from every other point at a constant rate. There is no expansion from a particular point. We know about this expansion due to the red-shift of galaxies. Since the universe has no edge - it is unbound - it has no centre.
In the fully developed Aristotelian system, the spherical Earth is at the center of the universe, and all other heavenly bodies are attached to 47–55 transparent, rotating spheres surrounding the Earth, all concentric with it. (The number is so high because several spheres are needed for each planet.)
The center of our galaxy lies in the direction of the constellation Sagittarius (near the trees, left). The Milky Way is one of over a hundred billion galaxies in the universe, but it's the only one we can explore from the inside.
