How can the Universe expand if its infinite?
The other answers simply explain that an infinite universe can continuously expand because the increase in size is filled with space, not new matter..
How long will the universe last?
It is expected that between 1011 (100 billion) and 1012 (1 trillion) years from now, their orbits will decay and the entire Local Group will merge into one large galaxy.
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.
How many universes are there?
The multiverse. If we define “universe” as “all there is” or “all that exists,” then obviously, by definition, there can be only one universe. But if we define “universe” as “all we can ever see” (no matter how large our telescopes) or “space-time regions that expand together,” then many universes may indeed exist.
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.
Who is the creator of universe?
In the new work, The Grand Design, Professor Stephen Hawking argues that the Big Bang, rather than occurring following the intervention of a divine being, was inevitable due to the law of gravity. In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe.
Who created God?
Having established who created God, we would then have to answer the question of who created God’s creator. In The God Book, deist Michael Arnheim writes: The atheist objection is that if God created the universe, who created God?
Does the universe have a center?
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.
Is the universe going to expand forever?
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.
What does it mean for space to expand?
“Space is expanding” means distances are increasing. Suppose two objects are placed in space some known distance from each other, not moving relative to each other. If the space they are in expands, the points will move away from each other.
Can you reach the 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.
Will the Earth die?
By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
What is beyond the universe?
[+] In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
What happens when two galaxies collide?
The Milky Way galaxy and the Andromeda galaxy are moving towards each other on a collision course. … Instead, as galaxies collide, new stars are formed as gasses combine, both galaxies lose their shape, and the two galaxies create a new supergalaxy that is elliptical.
