Is there an edge of the universe?
As far as we can tell, there is no edge to the universe.
Space spreads out infinitely in all directions.
Furthermore, galaxies fill all of the space through-out the entire infinite universe.
This conclusion is reached by logically combining two observations..
How can the universe be infinite?
If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. … In the infinite case, you wouldn’t have enough curvature for spacetime to form the hypersphere.
Will this 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 is beyond outerspace?
If by outer space you mean all that surrounds the Earth and stretches into all directions as far as people can see, then you’re talking about what astrophysicists call the universe. For there to be anything outside of the universe supposes that it has an edge, which is a problematic supposition for physicists.
What is beyond the end of the universe?
Beyond the Hubble Volume. Astronomers think space might be infinite, with “stuff” (energy, galaxies, etc.) distributed pretty much the same as it is in the observable universe. … Beyond the Hubble Volume you won’t just find more, different planets. You will eventually find every possible thing.
How long will universe last?
The universe will cease to exist around the same time our sun is slated to die, according to new predictions based on the multiverse theory. Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of years more.
Will the Big Rip happen?
The rate of this expansion may eventually tear the Universe apart, forcing it to end in a Big Rip. … Many theoretical physicists believe the Universe will end, and it could happen at any point between 2.8 billion years and 22 billion years from now.
What is beyond the universe for it to expand into?
The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.
What is beyond our galaxy?
Beyond our galaxy itself, which holds our solar system and everything beyond it, are other galaxies. The nearest galaxy is Andromeda, which will collide with the Milky Way galaxy in about 4 billion years. The Milky Way is part of the Local Group, which consists of 30 galaxies.
Does space have an end?
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
Is nothingness possible?
‘Nothing exists’ is simple in the sense of being an easy to remember generalization. … There is no such thing as nothingness, and zero does not exist.
Are we in a void?
The large-scale structure of the universe, illustrated here by the Millennium Simulation. The image shows how matter in the universe is organized into filaments and voids.
What was before the universe?
The initial singularity is a gravitational singularity predicted by general relativity to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Is our universe infinite?
Observations, including the Cosmic Background Explorer (COBE), Wilkinson Microwave Anisotropy Probe (WMAP), and Planck maps of the CMB, suggest that the universe is infinite in extent with a finite age, as described by the Friedmann–Lemaître–Robertson–Walker (FLRW) models.
Can the universe suddenly end?
As long as the amount of stuff doesn’t go over a critical threshold, the universe will continue to expand forever, and eventually suffer heat death, freezing out. But if there’s too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract.
