Does the universe have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity)..
What is beyond the end of 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.
What is more powerful than a black hole?
A neutron star can be at most about three times the mass of the sun, black holes are nearly all larger than that, so the gravitational pull of the black-hole is greater.
Where does space 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.
Where does space end and heaven begin?
Karman lineSo where does Earth stop and the heavens start? According to a paper that was published in the Journal of Geophysical Research-Space Physics, the border between the two—the so-called Karman line—sits 73.2 miles (188 kilometers) above Earth’s surface.
What is the farthest thing in the universe?
The most distant galaxy ever discovered in the known Universe, GN-z11, has its light come to us from… [+] The distance from this galaxy to us, taking the expanding Universe into account, is an incredible 32.1 billion light-years. The most distant galaxy of all is GN-z11, located 32.1 Gly away.
What is the most powerful thing in the universe?
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
Will a black hole eventually swallow the universe?
9. If nothing can escape from a black hole, then won’t the whole universe eventually be swallowed up? The universe is a big place. … But collisions won’t happen indefinitely because the universe is big and because it’s expanding, and so it’s very unlikely that any sort of black hole runaway effect will occur.
How long will universe last?
Assuming that dark energy continues to make the universe expand at an accelerating rate, in about 150 billion years all galaxies outside the Local Supercluster will pass behind the cosmological horizon.
Do things exist when not observed?
An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.
What is on the other side of a black hole?
The event horizon is a proposed boundary around a black hole. On the other side of it, the gravitational pull of the black hole is so strong that, in order to escape it, an object would have to be moving faster than the speed of light, a feat that almost all physicists agree is impossible.
Are there other universes?
Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.
What is beyond the known universe?
Beyond our observable Universe lies the unobservable Universe, which ought to look just like the part we can see. The way we know that is through observations of the cosmic microwave background and the large-scale structure of the Universe.
