 sara03 (1548) | 2 years ago |  High friend, an interesting article on end of universe.
"Scientists have been pondering for years how the universe will end, and now two University of Michigan astrophysicists have come up with a scenario that may make everyone breathe a little easier.
The good news is that the end is not near. The bad news is that when it does come, it's not going to be pretty.
The stars, the sun and the earth will die -- evaporating into radiation -- and there will be no light, only a vast soup of subatomic particles.
Greg Laughlin"The fate of the earth is still in some sense not certain," astrophysicist Greg Laughlin says. "It's not clear if it will be destroyed by the sun or whether it will escape being destroyed when the sun turns into a red giant."Laughlin and his University of Michigan colleague, Fred Adams, were in Toronto to describe their scenario at the winter meeting of the American Astronomical Society.
The universe as we know it, with stars and planets and life, is only temporary and is actually rather young, about 10 billion years old.
'We don't live in a preferred time'
nebula"We don't live in a preferred time," Adams says. "Our current cosmological epoch has no central place in time." The here and now is but a brief phase, he says, in a sweep of time and change almost unfathomable to the human mind.
Using new information about the nature of the universe, they divided time into segments measured by what they call cosmological decades. Ten billion would be decade 10, or 10 multiplied by itself 10 times.
They call current time the Stelliferous, or star-filled era, a period that is about half over. At 20 billion to 30 billion years, the sun will expand into a red ball and die, overwhelming Earth with the heat. Oceans will boil and evaporate, and other planets near the sun also will burn, leaving nothing but orbiting chunks of barren rock.
At cosmological decade 15 (10 multiplied by itself 15 times), the Degenerate Era begins. Other stars will begin to die off as they burn up their nuclear fuel and the firmament as we know it ceases to shine."If you wait long enough," Adams says, "all of the stars in the universe will eventually run out of fuel and burn out."An epoch of dead stars
The universe then enters a second stage, an epoch of degeneration.
graphic"It's an era when most material is locked up in dead stars such as black holes, or white dwarfs," Laughlin says.
This era, 100 trillion trillion trillion years from now, marks the end of all planets. Protons, the subatomic particles at the center of the nuclei of atoms, will begin to decay. Without protons, matter evaporates into radiation. Carbon-based life is not possible, because carbon does not exist without protons."The proton decay epoch will initiate the most significant change in the universe," Adams says.
black hole
Cosmological decade 38 begins the black-hole era. Black holes feast on material sucked in from nearby and grow larger. This continues for about 60 cosmological decades.
And then, at cosmological decade 100, the dark era begins."Once the black holes have radiated away, the universe will consist of a diffuse sea of electrons, positrons, neutrinos and radiation," says Adams.
End of the world date: 1 plus 200 zeroes
And the universe is totally black. "Let us live peacefully and live for others happily

| | | 2. sara03 (1548) | 2 years ago | Good posting and discussions. Life it is said is short and unpredictable. Death is not in our hand. There is a belief from ages th universal is going to end and all the evils will be destroyed. it is written in our great epics, Bible and other holy scripts.Whatever said and done, let us help others,live happily and peacefully.
An interesting article on this.
"Scientific speculation about the ultimate fate of life in the universe merges almost seamlessly into science fiction. Many works describe the end of the universe—occasionally purely educational exercises describing theories of the day, more often exploiting its potential as the ultimate sense of wonder plot device, or satirising the pretensions of humanity in general and cosmologists in particular. At its best (and sometimes at its most bombastic) science fiction can try to suggest a scientific eschatology that searches for meaning in the face of the new knowledge. Countless sci-fi and fantasy works use the threatened destruction of the universe as their plot device, usually with an evil supervillain and/or the incompetence of humanity as the cause, and usually with human ingenuity saving the day.
The topic of heat death was explored in science fiction as early as 1895 in H G Wells' The Time Machine, which includes an evocation of the heat death of the universe as imagined by scientists like Lord Kelvin at that time. In the absence of a modern dynamic cosmology, this consisted of the fading out of the Sun to an exhausted red ember, and a vision of Earth as a cold and bland eroded desert. As the understanding of cosmology increased, so too did the scope of science fiction. Isaac Asimov's short story, "The Last Question" was published in 1959, and posits a universe experiencing heat death, and a future human computer technology so powerful that it finally discovers how to reverse the process by igniting what is, in effect, a new Big Bang. When Asimov published this story, in 1959, heat death was still the only scenario discussed in this entry to have been articulated.
The Big Crunch as the fate of the Universe was explored in science fiction as early as Poul Anderson's 1970 novel Tau Zero which posits a cyclic universe where the big crunch will be surrounded by a cloud of hydrogen, and that a starship could navigate a course to avoid the singularity and emerge into the new universe after the subsequent big bang.
Religion is not wholly excluded from science fiction's explorations of the end of our universe. Arthur C. Clarke's short story "The Nine Billion Names of God" takes non-scientific eschatology seriously. Its famous last line ominously chronicles the end of the universe as observed by mankind: Overhead, without any fuss, the stars were going out.
Not only a source of fear or hope, the end of the universe has been used for satirical and comedic effect. Milliways, The Restaurant at the End of the Universe, is a fictional location in Douglas Adams's science-fiction series The Hitchhiker's Guide to the Galaxy. The entire restaurant and its patrons are projected through time via a "time bubble" to the point at which the Universe ends. The ceiling is made of glass so the restaurant guests can watch the universe end as dinner entertainment.
The concept of an end to the universe has inspired some authors to explore the more human-centric topics of fate and free will, In Kurt Vonnegut's classic novel Slaughterhouse Five, the primary character is a war veteran who is contacted by aliens from the planet Tralfamadore who claim that one of their scientists will accidentally destroy the universe while testing a new type of spaceship fuel. Tralfamadorians are aware of this event because they perceive all of time instantaneously, in a similar way to how someone would observe an entire range of mountains in one instant."

| | | 3. lucky_witch (2112) | 2 years ago |  well, yeah maybe. if we continue abusing the environment then maybe there would coma a time that life in the universe will end and we are on the first line. I dont know if sun would stop from shining. I really dont have the idea... but for us I believe that soon life on earth will come to end. And we can do something about it.

| sara03 (1548) | 2 years ago | You are right Buchi_bulla. Fearing and worrying for something which you are not sure will only ruin your life style. Instead face the challenges in life positively. We know life and death are part of our life cycle and let us live for some goals and purpose which will erase discomforts.
nice day. | |

| | | | | 7. Thai_Guy (676) | 2 years ago |  no i don't.B/c,i believe that after we die,we reincarnate into another spirit.I don't believe that there is a end to anything.But the end is a new beginning of Life.

| sara03 (1548) | 2 years ago | Right friend, the physical form of body only is
getting into the mud or burnt after death but
our inner spirit has no death and it transforms
into another body, i,e called re incarnation.
nice point | |
|
| | | | 8.  juntech (1608) | 2 years ago |  I dont think so?
since the universe is endless and so are the life forms in it.
our race might extinct,but im sure there are other life forms out there other than humans....what do you think?
