Is it possible that the universe is infinite?
Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.
Can the universe exist forever?
Theories about the end of the universe. The fate of the universe may be determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the "Big Freeze" scenario below.
Will the entire universe ever end?
In either case, you could never get to the end of the universe or space. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.
Why can't the universe be infinitely old?
The concept of entropy dictates that if the universe (or any other closed system) were infinitely old, then everything inside would be at the same temperature, and thus there would be no stars and no life.
Did Einstein think the universe was infinite?
Einstein was not comfortable with the notion of an infinite Universe that contained a finite amount of matter. He believed that a spatially bounded, and thus finite, Universe was a much more natural choice from the point of view of general relativity.
Does space have an end?
By all accounts, the universe appears to have no boundary. It has no end. On the other hand, the universe is only as big as the area expanding to fill it all up. And it's been doing that since the big bang.
Who is universe dad?
Lord Siva the Father of Universe:Lord Rama's worship of Lord Shiva.
Is space infinite or finite?
Space must then itself also be finite because it is merely a receptacle for material bodies. On the other hand, the heavens must be temporally infinite, without beginning or end, since they are imperishable and cannot be created or destroyed.
Can we create a new universe?
We explore the possibility that a new universe can be created by producing a small bubble of false vacuum. The initial bubble is small enough to be produced without an initial singularity, but classically it could not become a universe - instead it would reach a maximum radius and then collapse.
Do other universes exist?
In recent years, there have been proponents and skeptics of multiverse theories within the physics community. Although some scientists have analyzed data in search of evidence for other universes, no statistically significant evidence has been found.
How will time end?
According to Einstein's General Relativity, which is our best current description of space and time, the only place where time – and also space – ends is in a so-called singularity. This involves gravitational forces becoming so intense that space and time lose all meaning.
What exists outside the universe?
What lies beyond the universe? We are not sure but can theorize what lies beyond the universe that we know. Outside the bounds of our universe may lie a "super" universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever.
Can infinity exist without time?
Originally Answered: Can infinity exist beyond space and time? No, because infinity is a mathematical concept, mathematics is a human construct, and humanity can't exist outside of space and time. Mathematical objects are not real. They're abstractions.
What was before the universe?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang. The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time in the history of our universe.
Is space theoretically infinite?
If we assume that our current laws of physics are correct, we can set limits on how large, at least, the Universe must be before it curves back on itself. But, big as that is, it still isn't infinite.
Does Stephen Hawking believe the universe is infinite?
Stephen Hawking did not propose the idea of infinite universes to explain quantum fluctuations. While he made significant contributions to theoretical physics, including research on black holes and the nature of the universe, his work did not specifically endorse the concept of an infinite number of universes.
Who first said the universe is infinite?
10 DECEMBER, 1936 Whole No. 440 Nicolas Copernicus and an Infinite Universe By GRANT McCOLLEY For many decades the historians of science have heralded Giordano Bruno as the first to advocate the ancient doctrine of an infinite universe as a corollary to the Copernican theory.
Does space have a smell?
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
Is there another Earth with humans?
The Moon is the only other place humans have visited. No other planet in our solar system currently has the conditions to support life as we know it on Earth. Even if scientists discover another habitable planet outside of our solar system, humans do not yet have the technology to visit it.
Who created space?
It appears that space was created in the Big Bang, 13.8 billion years ago and has been expanding ever since. The overall shape of space is not known, but space is known to be expanding very rapidly due to the cosmic inflation.
Who is God of universe?
Vishnu, Lord of the universe, is a Hindu God known to have reincarnated into more than one form called Avatars. In other words, he is recognizable through the faces of other gods who receive praise within the Hindu beliefs. Here we have sculptures of Vishnu and a few of his forms ranging 8th-19th century.
Who is universe 1 God?
The God of Destruction of Universe 1 is Iwan, the Supreme Kai is Anato, and the Angel is Awamo.
Who destroyed 6 universes?
At some point in time, Zeno destroyed 6 of the then-existing 18 universes. In the manga, Zeno held an All Universe Hide and Seek Tournament, but when Beerus hid and fell asleep for fifty years during the tournament, it had to be cancelled.
Is it Dark in space?
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Are we alone in the universe?
“The universe is so vast and the building blocks of life are so abundant in the cosmos. The number of planets in the cosmos is so large that it's very unlikely that life on Earth is the only form of life that exists out there,” Margot said.
Is it cold in space?
Outer space has a baseline temperature of 2.7 Kelvin, minus 453.8 degrees Fahrenheit or minus 270.45 degrees Celsius, according to LiveScience. However, this temperature is not consistent throughout the solar system.
Do wormholes exist?
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
Where do black holes take you?
When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. For all practical purposes the matter has disappeared from the universe.
Is the universe intelligent?
There's no evidence that the universe is "intelligent". But your question was "can" and thus we're dealing with hypotheticals. As such, yes, the universe can be less intelligent than us.
Can dreams be another reality?
The Multiverse Hypothesis
This hypothesis proposes that our universe is just one of many parallel universes, each with its own set of physical laws and possibilities. If this theory holds true, it suggests that dreams and lucid dreaming may provide windows into these alternate realities.
How many dimensions exist?
In everyday life, we inhabit a space of three dimensions – a vast 'cupboard' with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.
Do we live in a multiverse?
As far as we currently know, there is a single expanding blob of spacetime speckled with trillions of galaxies - that's our Universe. If there are others, we have no compelling evidence for their existence.
What year will time end?
The End of Time
As for time ending, as far as we can tell time will have no end in the future. Our universe is expanding every day, and it appears that it will continue to do so for eternity.
Will time end physics?
Time has no beginning and no end. In some Big Bounce models, the universe only bounces once. In others it goes through an infinite number of bounces, constantly expanding and contracting, like an accordion that never stops playing. All of these scenarios show us what is possible, not necessarily what is true.
Has time always existed?
The passage of time is not an illusion, it's a fundamental aspect of reality, something that existed before even The Big Bang. By studying the nature of novelty, the life sciences could help us prove time fundamentalism, argues Lee Cronin.
Are multiverses real?
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.
What is after our universe?
It's possible that there isn't just one universe, and that beyond our universe there are others. We could be living in just one small part of a “multiverse”. Perhaps our universe is contained within its own distinct region of space, separated from other universes by vast expanses of nothingness.
Why does space exist?
General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field.
Does zero really exist?
zeroes just like infinity, probable do not exist in the "real" world. There is not a single observed entity that has a no properties, by the very definition, if it did, it would be unobservable. The closest things to "zero" as we get is empty space, but quantum indeterminacy prohibits completely zero energy in space.
Can light travel till infinity?
Does light travel forever or does it eventually fade? Light can travel indefinitely, but it can be absorbed by other objects or scattered in different directions. This is why light from distant stars eventually becomes too faint to see.
Is time really a dimension?
Physics > Space and Time
According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.
Does empty space exist?
Even though the density of interstellar space is billions of times lower than even our emptiest human-made vacuum chambers, it's not 100% percent empty. To reach the emptiest places in the universe, you have to travel to the cosmic voids, the vast regions of nothingness that dominate the volume of the cosmos.
Is space dark energy?
Like the jelly beans in this jar, the Universe is mostly dark: about 96 percent consists of dark energy (about 69%) and dark matter (about 26%). Only about 5 % (the same proportion as the lighter colored jelly beans) of the Universe— including the stars, planets and us—is made of familiar atomic matter.
When did time exist?
According to the standard big bang model of cosmology, time began together with the universe in a singularity approximately 14 billion years ago.
Did Einstein think the universe was infinite?
Einstein was not comfortable with the notion of an infinite Universe that contained a finite amount of matter. He believed that a spatially bounded, and thus finite, Universe was a much more natural choice from the point of view of general relativity.

Did Aristotle believe the universe was infinite?
He placed the earth at the center of a finite universe. For Aristotle, the universe is decidedly not infinite; he argued that there were potential infinities, but not actual infinities. Not a potentially infinite universe?
What was Stephen Hawking's last theory?
Stephen Hawking's last theory was that the universe is a four-dimensional membrane in a five-dimensional space. This theory is known as the "holographic principle". The holographic principle states that all the information about a physical system can be encoded on its boundary.
Why can't we observe an infinite universe?
We can't see anything past this horizon because light has not reached Earth from beyond the cosmic light horizon, since the time required for this would be greater than the present age of the universe. With time, more light from more remote places will reach Earth, and the size of our observable universe will increase.
What did Einstein say about the universe?
The full quote from Albert Einstein is: “I think the most important question facing humanity is, 'Is the universe a friendly place? ' This is the first and most basic question all people must answer for themselves.
Can the universe have an infinite past?
If the universe did not have a beginning, then the past would consist in an infinite temporal sequence of events. An infinite temporal sequence of past events would be actually and not merely potentially infinite. It is impossible for a sequence formed by successive addition to be actually infinite.
What would space sound like?
Sound cannot travel through space, thanks to the lack of air to act as a medium. Instead, NASA has produced musical tones from the same telescope data that is manifested into pictures such that you can now hear the beauty of space.
Can you hear in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
Did NASA find a second Earth?
A new "super-Earth" has been discovered in a nearby solar system's habitable zone, according to NASA. The planet, designated as TOI-715 b, is "about one and a half times as wide as Earth" and in a system that is only a measly 137 light-years from Earth.
Can humans live on Kepler-452b?
Scientists don't know if Kepler-452b can support life. What is known about the planet is that it is about 60 percent larger than Earth, placing it in a class of planets dubbed "super-Earths," with an orbit of 385 days. Scientists believe that Kepler-452b is about 6 billion years old, much older than Earth.
How will the universe end NASA?
How long will the universe exist?
Will there be an end of time?
Why does life exist?
What is the big rip theory?
Are we alone in the universe?
If the universe had enough matter in it, gravity would overcome the expansion, and the universe would collapse in a fiery “big crunch.” If not, the expansion would never end — galaxies would grow farther and farther away until they pass the edge of the observable universe.
