The farthest object from Earth ever observed is an infrared source known as GN-z11, located 13. 4 billion light-years (or around 0. 136 gigaparsecs) away from Earth. This means that the light we currently observe from GN-z11 left the source a mere 400 million years after the Big Bang.
GN-z11 is also the oldest and most distant known galaxy in the observable universe. Apart from GN-z11, other objects may exist beyond our observable universe. Some theories even suggest that the universe is infinite, making it impossible to determine the farthest thing from Earth.
Which is the farthest object in the universe?
The farthest object currently known in the universe is the GN-z11 galaxy. This galaxy was discovered in 2016, and is estimated to be approximately 32 billion light-years away from Earth. It is one of the oldest and most distant galaxies ever discovered, and is believed to have formed just 400 million years after the Big Bang.
Studies of the galaxy have revealed that its stars are a whopping 25 times more massive than the sun and are much younger than previously thought. Its distance and age give astronomers an unprecedented glimpse into the early universe and the formation of galaxies.
What is outside the universe?
The answer to this question is not entirely clear, as it is not known whether or not anything exists beyond the universe. Some scientists and philosophers theorize that there may be other universes, a concept known as the multiverse, while others argue that there is only one universe.
There is also some speculation that the universe is finite and has an end, in which case what lies outside of the universe would be unknown. Alternatively, it could be argued that the universe is infinite, meaning that there is no specific “outside” of the universe.
Ultimately, the answer to this question is uncertain, as it is not possible to observe anything beyond the limits of the observable universe.
What’s farther than the Milky Way?
The Milky Way is a large spiral galaxy that is home to our Solar System, and is part of the Local Group of galaxies. As such, it is part of an even larger structure known as the Virgo Supercluster, which is a group of over two thousand galaxies that are all gravitationally bound together.
Beyond the Virgo Supercluster, the closest large structure of galaxies is the Local Void, which is a region of mostly empty space. Then, there is the Shapley Supercluster, a massive concentration of galaxies that stretches across portions of the Virgo and Hydra clusters.
After that, we enter into a region known as the Great Attractor, which is an area that is pulling most galaxies towards it with a gravitational force. Finally, at the very edge of the observable Universe, galaxies become much more sparse as one moves further away from the Earth.
There could be other structures of galaxies out beyond the observable universe, but we have no way to verify that, since we are limited by the speed of light in how far we can observe.
Does space ever end?
No, space does not have an end. Scientists believe that space is infinite and continues forever in all directions. Astronomers consider our universe to be expanding, meaning that it’s getting bigger as time passes.
This means that the space within the universe is also expanding, creating more space and leading to the conclusion that there is no physical end to space. To further support this concept of infinity, consider that if there were an end to space, one would expect to find evidence of what lies beyond it.
However, no such evidence or proof of a definite end has been found, leading scientists to believe that space is without a definitive beginning or end.
How many dimensions exist?
The exact number of dimensions that exist is a topic of great debate amongst scientists and mathematicians. Some argue that there are as many as 11 dimensions while others maintain that the universe is made up of only 3 spatial dimensions.
Many believe that there must be more than three dimensions to explain certain phenomena such as quantum mechanics and string theory. Specifically, string theory proposes that the universe has nine or ten dimensions, with the extra dimensions being too small for humans to observe.
In addition, some argue that time may be considered a fourth dimension, although this is not universally accepted. Ultimately, whether or not dimensions beyond the three that are perceptible to humans exist is a topic of ongoing scientific investigation.
What is at the end of space?
At the end of physical space, there is nothing. Astronomers are unable to see anything beyond what they can observe with telescopes, which suggests that there is no more physical space outside of our observable universe.
However, this does not necessarily mean that nothing exists outside of our physical realm, as some theorists and physicists propose that there could be other universes or realms of existence beyond ours.
Some even speculate that time could be an unending, infinitely looping cycle instead of an arrow that ends in one single point. Despite these interesting theories, there is still no definitive answer as to what lies outside of our physical space, if anything.
