There are approximately 14.26 gigaparsecs (46.5 billion light-years or 4.401026 meters) between Earth and the limit of the visible cosmos in either direction. As a result, the visible universe is a sphere with an approximate diameter of 28.5 gigaparsecs (93 billion light-years or 8.81026 meters).

How far can we see into the universe?
Since the Big Bang occurred 13.8 billion years ago, it’s reasonable to assume that the furthest things we may conceivably observe are 13.8 billion light-years distant. However, this is not the case. However, not only is this not true, but the most distant object we can see is 46.1 billion light-years away, which is more than three times as far away as we can see.
Where is the end to the universe?
Since the Big Bang occurred 13.8 billion years ago, you may anticipate the farthest things we can possible view to be 13.8 billion light-years distant. However, this is not the case. It’s also false because the farthest distance we can view is 46.1 billion light-years away, which is more than three times as far as we can see from here on Earth!
Is there an end to the universe?
Scientists today believe that the cosmos does not have an end – a point where the galaxies come to a halt or where there would be some sort of barrier marking the end of space – and that there is no such region. Nobody, though, knows for certain.
Does space ever end?
No, they do not think that there is an end to the universe. However, we can only view a limited amount of what is out there at any given time. The universe is 13.8 billion years old, which means light from a galaxy more than 13.8 billion light-years away hasn’t had enough time to reach us yet, and as a result, we have no way of knowing whether or not a galaxy of that distance exists.
What is beyond the universe?
Because the cosmos is the only thing that exists, it is infinitely large and has no boundary, hence there is no such thing as an exterior to speak of. Yes, there is an outside to our observable area of the cosmos, no doubt about that. There is only so much time in the universe, and only so much light can travel in a given amount of time. Present estimates place the current breadth of the visible universe at around 90 billion light years.
How many universes are there?
Only one universe, and only one universe, may be given as a relevant solution to the question of how many worlds there are. Furthermore, some philosophers and mystics believe that even our own universe is a deluding illusion.
Is time Travelling possible?
To summarize: Yes, time travel is a genuine possibility. However, it is not quite the same as you may have seen in the movies. While under specific situations, it is possible to perceive time advancing at a rate other than one second every second, or even faster.
Who created space?
Georges Lemaître, a Belgian physicist who worked on the “Big Bang” theory of cosmology, initially suggested it in 1931. This is the basis for the present idea of outer space. According to this hypothesis, the cosmos started as an extremely dense form that has since experienced constant expansion.
What existed before the universe?
The initial singularity is a singularity anticipated by some versions of the Big Bang theory to have existed before the Big Bang and assumed to have held all of the energy and spacetime in the Universe. It is also known as the initial singularity of the universe.
What happens when the universe dies?
A massive black hole may rush across our universe, absorbing all of the “dead” stuff from our “big bang,” and then crash with something else, causing a brand new big bang from the ground up. When the Universe has finished with you. The Black Holes will undergo a phase change and become Neutron Stars, which will explode in the most massive explosions ever witnessed.
How cold is space?
The distance between gas and dust particles increases as we travel beyond our solar system and beyond the far reaches of our galaxy, into the immense nothingness of space. As a result, the capacity of gas and dust particles to transmit heat decreases. Temperatures in these arid regions can drop to as low as -455 degrees Fahrenheit in certain cases (2.7 kelvin).
How long is 1 hour in space?
Answer: The product of that number multiplied by one hour is 0.0026 seconds. In this case, a person in that deep space location would have a clock that would operate for one hour, while that individual computed that our clock ran for 59 minutes and 59.9974 seconds.
Is space hot or cold?
When atoms come to a full stop, they are said to have reached absolute zero. At an average temperature of 2.7 Kelvin, space is just a little bit warmer than that (about minus 455 degrees Fahrenheit ). However, much of the available space is, well, empty space. It is completely immobile.
