Unfortunately, since universe is technically expanding faster than the speed of light (due to the expansion of space between matter), it is theoretically impossible to ever reach the “edge” of the universe, since it will always be moving away faster than we could ever move towards it!Furthermore, can you get to the edge of the universe?
The implication though, is that there is no "edge"; there is no place to go where the universe just ends and one could look in some direction and see what's beyond it. One analogy often used to describe this edgeless universe is the surface of a balloon.
Also, how long would it take to travel to 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.
Considering this, what happens if you reach the edge of the universe?
The edge of the observable universe cannot keep up with the expansion of the universe so that many galaxies are eternally beyond our observation.
What is beyond the edge of the universe?
Technically, this is the farthest point in space and also the farthest in time that we can observe. That essentially forms the edge of the “Observable Universe”. What lies even beyond that is what is known as the “Opaque Universe”. This marks the limit of what we can observe but not what we can imagine.
Does space have a smell?
According to astronauts, they all smell like space. While each astronaut smells something a bit different, they all agree 'space stinks'. Obviously, space is a vacuum, so no one has really 'smelled' it before in the traditional sense of the word. If you tried, you'd die.Is time an illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.What is the universe inside of?
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.Where in the universe are we?
Well, Earth is located in the universe in the Virgo Supercluster of galaxies. A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group. Earth is in the second largest galaxy of the Local Group - a galaxy called the Milky Way.How is space infinite?
Our universe is just a finite number of galaxies rushing away from each other inside this empty infinite space—like a solitary skyrocket exploding and sending out a doomed shower of sparks." But many cosmologists say, no, there are an infinite number of galaxies in our infinite space.What is outside the 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.How long does the universe have left?
14 billion years
Will we ever travel to other galaxies?
According to the current understanding of physics, an object within space-time cannot exceed the speed of light, which means an attempt to travel to any other galaxy would be a journey of millions of earth years via conventional flight.Where is the end of space?
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.Is the universe a sphere?
Shape of the observable universe The observable universe can be thought of as a sphere that extends outwards from any observation point for 46.5 billion light years, going farther back in time and more redshifted the more distant away one looks.What is dark energy in the universe?
Dark Energy. Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion.Can we see the entire universe?
There is no evidence that the universe has an edge. The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see - more than 10 billion light-years, or about 6 billion trillion miles.What does the universe look like?
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. They come in a great diversity of types, shapes, sizes and masses.How fast is the universe expanding?
In 2001, Dr. Wendy Freedman determined space to expand at 72 kilometers per second per megaparsec - roughly 3.3 million light years - meaning that for every 3.3 million light years further away from the earth you are, the matter where you are, is moving away from earth 72 kilometers a second faster.What is the altitude of space?
100 km
How vast is space?
Today we are fairly confident that the Milky Way is probably between 100,000 and 150,000 light years across. The observable Universe is, of course, much larger. According to current thinking it is about 93 billion light years in diameter.How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
