Almost 14 billion years ago an incredible effect took office . It was a elephantine explosion where everything began : matter , energy , time and even space itself . Our whole creation came into existence from a single point . What would it be like to live through the closing of all that ? It depends on whose theory you believe .
In 1950 , British astronomer Fred Hoyle dubbed this titanic explosion the Big Bang ( for the most part to make fun of the idea ) . But this was n’t like an burst where everything is hurtle into space , because there was no space before the Big Bang . blank itself was created right along with matter and clip , and it is extend , too . The consequence is that everything in the existence is gradually growing further away from everything else .
Another way in which the universe resembles an burst is that it is becoming cool as it expands . At the instant of the Big Bang , the temperature of the universe was an unbelievable 100,000,000,000,000,000,000,000,000,000,000 degrees K ( 1032 level C , 1.832 degrees F ) . Today , 13.7 billion year later , the ordinary temperature of the population is a chilly 2.725 degrees K ( ‑454.761 degree F , ‑270.425 degrees C ) .
The End of Everything
What will become of the universe in the distant future ? Will it continue to lucubrate and coolheaded ? Or will the expansion finally add up to a stop ? Or perhaps it might start to crack back onto itself , in the same way that a ball toss into the air will slow down , stop and then fall back to Earth .
Will the universe then cease in a Big Crunch ? If this were to happen , the population would sign and , slowly at first , then quicker and faster , the Galax urceolata will arrive closer together . finally , the universe of discourse would no longer be large enough for separate galaxies or whizz and everything will merge , like snowbird compact into a solid snowball . As it shrink , the temperature of the world will increase staggeringly . at long last , at the end , the cosmos will survive as it was at the beginning : an infinitely small , endlessly dense , and infinitely red-hot point .
Will that level finally burst in another Big Bang , make a brand - new existence ? Have there been other Big Bangs and other universes before our own ? Is it a cycles/second that has gone on infinitely before and will continue endlessly into the future ? No one knows .
But most astronomers conceive that the universe will keep on expand . What will take place then ? The distances between the galaxies will arise greater and greater . All the wandflower beyond those of our local radical will eventually disappear into the impossible aloofness . In our own galaxy , the maven will gradually burn down out since there will be nothing left with which to create new ace . The universe around us will slowly maturate dimmer and dimmer .
With all of the energy in the cosmos used up , there will be no asterisk or planets or galaxies . The temperature will overleap to Absolute Zero ( ‑459.6 degrees F , ‑273.15 degrees C ) . Molecules and atoms will have no motion . They will only fall apart , leaving a universe filled with sub - atomic particles . Everything will be at the same temperature and chemical response will quit . No work can be done . No information will flow . Even news , view and imagination will lay off . Nothing will ever change . By then , perhaps 1000 billion years in the future , there will be nothing left of the cosmos but darkness , emptiness and absolute cold . It will be the Big Freeze .
Surviving the Big Freeze ?
A few uranologist believe that the Big Bang may not have been a unique outcome . They suggest that parent universes may give birth to new baby universes . This occur invariably . If they are correct , young population are form even as you read these Christian Bible . This intend that while your universe may come to an remainder there may be another universe somewhere that is not ending . All that ’s necessary is to essay to figure out some way to travel from one to the other .
These universes exist all around us . We are not cognisant of them , however . you may imagine our creation as being a like a vast sail of composition . The other universe of discourse are like other plane of paper . Some lie above ours , some below . We can move around on our sheet all we care . But we ca n’t see the sheets of report that dwell above us , nor the ones below . Even worse , we have no way of jumping off our sheet of newspaper publisher . If we could do that , we could journey from one universe to another as easy as you’re able to travel from one town to another on Earth .
Some scientists evoke that only a midget fraction of an in separates our population from the next one . But to make that parachuting would require vast total of energy . It would also require technology that does n’t yet exist .
The first affair , of path , would be to hear to find out if there even are any other universes . This wo n’t be an easy matter to do . Scientists have devised experiments that would name the existence of other universes . But these experiment would be among the most soft ever performed . So far no one has been able to successfully do one .
But if there are other universes , how could you locomote to one ? One way might be to expend a wormhole . This is a kind of tunnel associate two universes . Physics allows for the existence of wormholes , but no one has ever yet discovered one . But if lifelike wormholes are n’t found , would it be possible to make one ? sure enough . But doing so would demand tremendous amounts of energy . To make one the sizing of a pin hole would require the full vim generated by 10 billion stars in one year . Worse yet , it would postulate the innovation of negative energy . This is a form of energy that is theoretically potential , and for which evidence exists , but which no one has yet been capable to produce . At least not in the gigantic quantity that would be needed to create a orotund wormhole .
Building a New Universe
Perhaps it would n’t be necessary to find a unexampled universe if we could simply create a new one from scratch . This might not be as inconceivable as it sounds .
child universes are born when a area of space enters an unstable nation call a false vacuum . A false vacuum cleaner is make by the gravity generated by A-one - dense subject . It would n’t take much matter to do this . Astronomer Alan Guth has calculated that you would need to start with 1089 photon , 1089 electrons , 1089 positrons , 1089 neutrino , 1089 antineutrinos , 1079 protons and 1079 neutrons . This is only a few Panthera uncia . The false vacuum that was needed to create our present universe was very pocket-size . It may have been only 4 to 10 inch ( 10 - 26 cm ) wide . for make such a fictitious void from one ounce of matter , the density of the topic would have to be incredible .
Density is a measure of how close packed a substance ’s atoms are . The air in a balloon is not very slow because its atoms are spaced far aside . But a bowling ball the same size of it is very dense because the molecule in it are much closer together . And because a dense physical object hold more topic than one that is not very dense , it is heavier .
The denseness need to make the false vacuum is something like 6.2482 pounds per three-dimensional human foot ( 1080 gm / cm3 ) . That ’s 624 with eighty zeroes following it — more than six hundred billion , billion , billion , billion , billion , billion , billion , billion , billion , billion , billion , billion , billion pounds of matter crammed into a exclusive three-dimensional foot ! ( A cubic fundament [ 0.028 m3 ] of water count only 62 Pound [ 28 kg ] . ) That would be like taking all the matter in the entire universe and compressing it into a block smaller than a toaster .
Coming up with the few ounce of matter would be no trouble . The trouble would lie in compress it to such a microscopic volume of space that its compactness would generate enough sham vacuum to activate the birth of a universe of discourse . There is no way anyone can do that today .
But even if we could create a brand - new universe , we would still be faced with the problem of get into it . Again , we would need a wormhole . And as we ’ve fancy , even the midget wormhole would require the energy of billions of stars . One large enough for the integral civilisation of Earth to extend through would probably require more vigour than there is in the universe . But possibly we would n’t have to do that . perchance a pinhole is all we would take .
Some scientist have suggested something that might work best than sending humans or spaceships through wormholes . data does n’t require much space . It can be sent through the smallest imaginable porta . All the data needed to make a human being could turned into a numerical computer code . In fact , that is what the DNA in your jail cell is . It is a codification that contains all the information that was needed to make you . This data could be placed into a molecule - size of it golem prognosticate a nanobot . Nanobots would then be sent by the millions through the tiny wormhole into the new population . Each one would post the DNA computer code of thousands or even millions of different people . They would also incorporate the information needed to create more nanobots .
Eventually , some will set ashore on a synodic month or planet . They will utilize the raw stuff they see there to make copy of themselves . finally there will be billions of nanobots on the planet . They will then start creating jumbo biological factories . Using the DNA information that had been recorded in the nanobots , the manufactory would start quicken human existence . Perhaps in the remote future it might be possible to not only immortalise the desoxyribonucleic acid code of individual people , but their memories and personality , too . These could be implant in the unexampled body . If that were to come about , then the civilisation that die out along with its world would be born-again in a brand - raw one .
