What will be the fate (destiney) of the univers ?
Answers:
Only time will tell!
Read the bible. Genisis through Revelation. It's in there somewhere.
Big crunch!!
It will be whatever God wills it. There is nothing we mortals can do to change things, so just relax.
its all going to end.well the universe we are use to..it might recreate while its sucking in this side. The sun will eventually explode and so we either leave or get burned..we can only see and research that far.but as time goes on we find out new things by the day..they might discover that there is plenty of other universes out there..we won't be here to know
there are a couple of theories - that the universe will continue expanding - just going on and on..that it will begin contracting again and finally implode (yeah - big crunch as someone said). I believe it may well at some point be eaten by a giant rottweiller.
it started with the Big Bang. it will surely end with a Big Bang... but its a matter of time..no one knows when the time will come.
the big bang then dust.
Physically speaking, the universe will either expand boundless,
OR
The universe will collapse on itself, drawing everything down to an insignificantly small and very hot, very dense point in time.
There are basically two answers to your questions-
1) Our universe is expanding. so, if there is enough mass in the universe to pull itself back then it is predicted that our universe will ulimately collapse under its own gravity and end in a big crunch.
2)If there is not enough mass in our universe to pull itself back together then it will keep on expanding and go on forever.
Research for calculating the mass of the universe is going and and in a few years it will become evident where we are heading to.
the Univers is in constant change. when people will know for sure our Univers' birth i think that only at the moment we are going to be able to make hypothesis about the end. "first the cause than the effect"
Does it 'matter'
The sun is just a minor star, earth dead without sun? Earth may well implode? But i think mankind will probably destroy the planet! NUCLEAR WARFARE....The end.
imploding, and then another big bang etc etc
It's unpredictable, the Big Crunch might happen, The universe might not explode etc. Just rely on God.
The ultimate fate of our universe is a topic in physical cosmology. Rival scientific theories predict whether the universe will be of finite or infinite duration. Once the notion that the universe started with Big Bang became popular among scientists, the ultimate fate of the universe became a valid cosmological question, one depending upon the universe's average density of matter and rate of expansion.
The theoretical scientific exploration of the ultimate fate of the universe became possible with Albert Einstein's 1915 theory of general relativity. General relativity can be employed to describe the universe on the largest possible scale. There are many possible solutions to the equations of general relativity, and each solution implies a possible ultimate fate of the universe. Alexander Friedmann proposed one such solution in 1921. This solution implies that the universe has been expanding from an initial singularity; this is, essentially, the Big Bang.
An important parameter in fate of the universe theory is the density parameter, Omega (Ω), defined as the average matter density of the universe divided by a critical value of that density. This creates three possible ultimate fates of the universe, depending on whether Ω is equal to, less than, or greater than 1. These are called, respectively, the Flat, Open and Closed universes. These three adjectives refer to the overall geometry of the universe, and not to the local curving of spacetime caused by smaller clumps of mass (for example, galaxies and stars).
Observational evidence was not long in coming. In 1929, Edwin Hubble published his conclusion, based on his observations of Cepheid variable stars in distant galaxies, that the universe was expanding. From then on, the beginning of the universe and its possible end have been the subjects of serious scientific investigation. In 1933, Georges-Henri Lemaître set out a theory that has since come to be called the Big Bang theory of the origin of the universe. In 1948, Fred Hoyle set out his opposing theory of a static universe, called the Steady state theory. These two theories were active contenders until the 1965 discovery, by Arno Penzias and Robert Wilson, of the cosmic microwave background radiation, a fact that is a straightforward prediction of the Big Bang theory, and one that the Steady State theory cannot account for. The Big Bang theory immediately became the most widely held view of the origin of the universe.
When Einstein formulated general relativity, he and his contemporaries believed in a static universe. When Einstein found that his equations could easily be solved in such a way as to allow the universe to be expanding now, and to contract in the far future, he added to those equations what he called a cosmological constant whose role was to offset the effect of gravity on the universe as a whole in such a way that the universe would remain static. After Hubble announced his conclusion that the universe was expanding, Einstein wrote that his cosmological constant was his "greatest blunder".
Starting in 1998, observations of supernovae in distant galaxies have been interpreted as consistent with a universe whose rate of expansion is accelerating. Subsequent cosmological theorizing has been designed so as to allow for this possible acceleration, nearly always by invoking dark energy and dark matter. Hence recent theorizing about the ultimate fate of the universe allows for a nonzero cosmological constant.
The fate of the universe is determined by the density of the universe. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will not collapse.
1.The Big Freeze is a scenario under which continued expansion results in a universe that is too cold to sustain life. It could occur under a flat or hyperbolic geometry, because such geometries are a necessary condition for a universe that expands forever. A related scenario is Heat Death, which states that the universe goes to a state of maximum entropy in which everything is evenly distributed, and there are no gradients — which are needed to sustain information processing, one form of which is life. The Heat Death scenario is compatible with any of the three spatial models, but requires that the universe reach an eventual temperature minimum.
2.In an open universe, general relativity predicts that the universe will have an indefinite future existence, but will approach a state where life as we know it cannot exist. Under this scenario, dark energy causes the rate of expansion of the universe to accelerate. Taken to the extreme, an ever-accelerating expansion means that all material objects in the universe, starting with galaxies and eventually all life forms, no matter how small, will disintegrate into unbound elementary particles. The end state of the universe is a singularity, as the expansion rate becomes infinite. For a possible timeline based on current physical theories
3.The Big Crunch theory is a symmetric view of the ultimate fate of the universe. Just as the Big Bang started a cosmological expansion, this theory postulates that the average density of the universe is enough to stop its expansion and begin contracting. The end result is unknown; a simple extrapolation would have all the matter and space-time in the universe collapse into a dimensionless singularity, but at these scales unknown quantum effects need to be considered.This scenario allows the Big Bang to have been immediately preceded by the Big Crunch of a preceding universe. If this occurs repeatedly, we have an oscillatory universe. The universe could then consist of an infinite sequence of finite universes, each finite universe ending with a Big Crunch that is also the Big Bang of the next universe. Theoretically, the oscillating universe could not be reconciled with the second law of thermodynamics: entropy would build up from oscillation to oscillation and cause heat death. Other measurements suggested the universe is not closed. These arguments caused cosmologists to abandon the oscillating universe model.
4.The Multiverse (or parallel universe in the singular case) scenario states that while our universe may be of finite duration, it is but one universe among many. Moreover, the physics of the multiverse may permit it to exist indefinitely. In particular, other universes may be subject to physical laws differing from those that apply in our own universe.
5.If the vacuum is not in its lowest energy state (a false vacuum), it could collapse into a lower energy state. This is called the Vacuum metastability disaster. This would fundamentally alter our universe; the various physical constants could have different values, severely affecting the foundations of matter.
All the five above theories are convincing in their own ways.
Apparently 50,000 years from now the sun will get so hot (due to climate change) that it will form a suction and will start to suck everything in its way and eventually the earth will be sucked into it and noone will survive.
As stated, there are 2 possibles. One is that the universe continues to expand or, depending upon the value of the Hubble number, it will collapse in on itself. Once collapsed, there is a view that it may explode again, although with less force and then collapse, explode etc. like a bouncy ball.
E=MC2 + n
It all depends--if we live in a "closed" universe, then all the little particles that are all over space and moving outward will pitch in to provide the gravity needed to have the universe collapse on itself. It's like a pendulum, you start it with some kind of energy, then when it gets to a certain point it will swing back. That would go on forever if there was no friction involved in the pendulum. The universe will shrink down, then explode again, and on it goes.
If we live in an "open" universe, then the bits and pieces--all matter everywhere, will succumb to entropy and eventually come completely apart. Like throwing a tennis ball in space--man, it's gone.
it will continue expanding (stretching), stars will disappear, it will become a vast, empty, dark and cold universe - about 100 billion years from now.
All mass in the universe existed in the form of a single point source. This point source was the source of the big bang. As the universe expanded, all forms of cosmic objects were formed and expanded outward at a fantastic rate. If the big bang did not create a sufficient amount of mater, the universe will continue to expand indefiniately. This would result in all mater eventually becoming one type of cosmic particle, identical to each other at any point in the universe.
If, on the otherhand, a large enough quantity of mater was formed, there would be a point in the expansion of the universe where all mass had lost enough momentem that gravity would cause it to begin to collapse in on itself. Eventually it would collapse back to that point source and initiate another big bang. Expansion of the universe would begin again untill it reaches that point of collapse once again. Currently, scientist have not been able to find enough mass in the universe to indicate a big collapse. The one theoritical mater thought to exist is called dark mater. This dark mater is thought to supply enough mass to the universe to cause the gravitational collapse, once this mater has lost enough momentium. If the Big Bang and the Big Collapse is the destiney of the universe, it is possible that this cycle of expansion and collapse has happened hundreds or millions of times already. This Big Bang cycle would indicate that the universe has a finite size but would have an infinite ammount of mater. The concept of infinite mass in finite space is explained by relativity. As a object approaches the speed of light, one of the 3 dimensions of nornal space begins to get smaller and smaller untill only 2 dimensions of space exist. As the universe expands to very near the speed of light, cosmic objects, such as galaxeys, become stacked together like the pages of a book at the very fringe of the universe. If we on Earth were able to examine these fringe galaxies, we might be able to determine the speed of a particular galaxy at 98% the speed of light. Conversely, if there were observers on a planet around a sun in that distant galaxy, they would observe our Milky Way Galaxey moveing away from them at the same speed, 98% the speed of light. In closing, the universe could be considered to have no begining and no end; just an infinite cycle of repeating expand and collapse.
Mind boggling to say the least.
1 word..kaaaaaabooommm!!! he he
The expansion of the universe slowed as if it was going to stop and begin contracting but, then it began moving outwardly again and increasing speed. As the universe continues what is now called its inflation, we will become more and more lonely and isolated unless we meet up with another universal clump of expanding or inflating planets, stars, and galaxies.
As our stars implode and explode, they will create smaller stars and the process will continue with stars getting smaller and smaller until everything is just cosmic dust.
We may be well into the process. The clump of stars, planets, and galaxies we call our universe may be the result of the death of a much more massive star from a universe of larger stars where the separation is 100s of billions of light years instead of the itty bitty singularity concept we are now exploring.
Perhaps Pluto, freed from the ball and chain of a solar system that doesn't appreciate it, will begin working out and traveling through the universe collecting more and more of the cosmic cloud until it becomes very large and its increasing muscular compression will cause it to go Bigger Bang creating another bigger universe and kicking all the astrobullies' butts in the process.
Well, what happens when you stretch an elastic band too much.
Nice questi!
