Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction. No signal can travel faster than light, hence there is a maximum distance (called the particle horizon) beyond which nothing can be detected, as the signals could not have reached us yet.
Can we ever see past the observable universe?
Although we cannot observe farther than this cosmic horizon which is presently a distance of 46.1 billion light-years away, there will be more Universe to reveal itself to us in the future. The observable Universe contains 2 trillion galaxies today, but as time goes on, more Universe will become observable to us.
What does beyond the observable universe?
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.
Why is there no edge of the universe?
Since the part of the universe that we can see is flat and uniform, and since our corner of the universe is not special, all parts of the universe must be flat and uniform. The only way for the universe to be flat and uniform literally everywhere is for the universe to be infinite and have no edge.
Why can’t we see beyond the observable universe Reddit?
The truth is that we can’t actually observe what we call the observable universe in the usual sense, i.e. we can’t watch it in real time The reason is that it takes light from a distant object at least about as long to reach us as the distance from that object divided by the speed of light.
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 the biggest thing in the universe?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!.
What is beyond the universe?
The universe, being all there is, is infinitely big and has no edge, so there’s no outside to even talk about. The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there’s a bunch of other random stars and galaxies.
Who created the universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
What’s on the other side of space?
If space is infinite, there is nothing on the other side. If space is finite because it has been bent around upon itself because of gravity, then again there is nothing on the other side of it because there is no seam. It looks like the surface of a smooth ball which represents a piece of flat paper bent upon itself.
Can you reach the edge of the universe?
This distance is farther than 13.8 billion light-years because of the Universe’s expansion, but it’s still finite. However, we cannot reach all of it. The size of our visible Universe (yellow), along with the amount we can reach (magenta).
How many universes are there?
There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is one, only one universe.
How long would it take to reach the edge of the universe?
It’s Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that’s 749 million) years. The end of the known universe: 225,000,000,000,000 years (that’s 225 trillion) years.
How big is the observable universe Reddit?
Background: The farthest we can see is about 45-46 billion light-years away from us and this defines the edge of the observable universe. The universe is only ~13.7 billion years old but we can see things so far away because the space in between them and us has expanded.
Is there an edge to the universe Reddit?
There is an edge to the observable universe that is ~13.8 billion light years away (46 billion light years away with the expansion of the universe), which is a sphere centered around our observation device. This ‘edge’ is just a region for which no photons beyond that edge have reached our detector yet.
What happens when you reach the end of space?
It will expand forever; the galaxies within groups and clusters will merge together to form a giant super-galaxy; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes May 6, 2020.
Is time Travelling possible?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
What is inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don’t produce light, a black hole is not empty, It’s actually a lot of matter condensed into a single point. This point is known as a singularity.
What is the most expensive thing in the universe?
An astroid named 16 Psyche, after Cupid’s wife, was found to be made almost entirely of iron and nickel. That means, in current US markets, 16 Psyche is worth somewhere around $10,000 quadrillion (the world’s economy is around $74 trillion).
What is the smallest thing in the universe?
Quarks are among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can’t be observed outside of their respective hadrons.
What is the smallest thing on Earth?
Quarks are the smallest particles we have come across in our scientific endeavor. The Discovery of quarks meant that protons and neutrons weren’t fundamental anymore.
