What is on the other side of space?
If space ends, what’s on the other side.
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..
What is on the other side of a Blackhole?
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.
How old is our universe?
13.7 billion yearsMeasurements made by NASA’s WMAP spacecraft have shown that the universe is 13.7 billion years old, plus or minus about 130,000 years.
What is beyond the galaxies?
Scientists have long been unable to find exoplanets—planets outside the solar system—beyond the confines of the Milky Way. After all, our galaxy is a warped disc about a hundred thousand light-years across and a thousand light-years thick, so it’s incredibly difficult to see beyond that.
Can we see beyond our galaxy?
Answer: Yes, you can see a few other galaxies without using a telescope! … The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.
What is bigger than a universe?
The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! NASA’s telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
Is the space infinite?
Newsletter. First, it’s still possible the universe is finite. … The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago.
Can a star exist outside a galaxy?
Answer: No, not all stars are in a galaxy. They may have once belonged to a galaxy, but they are not a part of it any more. Some of these so-called “stellar outcasts” or “intergalactic stars” have actually been observed by NASA’s Hubble Space Telescope.
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.
Who created the universe?
In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.
Will entropy destroy universe?
Once entropy reaches its maximum, theoretical physicists believe that heat in the system will be distributed evenly. This means there would be no more room for usable energy, or heat, to exist and the Universe would die from ‘heat death’. Put simply, mechanical motion within the Universe will cease.
What is outside the universe?
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.
Is there an edge of the universe?
And although our observable universe has an edge, the universe as a whole is infinite and has no edge. … Many galaxies are so far away from the earth that the expansion of the universe causes them to recede from the earth at a speed faster than light.
How many galaxies are they?
The deeper we look into the cosmos, the more galaxies we see. One 2016 study estimated that the observable universe contains two trillion—or two million million—galaxies.
Will our universe end?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Are there other universes?
In fact there are almost too many other potential universes. Physicists have proposed several candidate forms of “multiverse”, each made possible by a different aspect of the laws of physics. The trouble is, virtually by definition we probably cannot ever visit these other universes to confirm that they exist.
What is beyond the observable 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.
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.
