Invisible Particles Larger Than Thousands of Galaxies Span the Universe

An ancient subatomic signature extends across the universe. It seems that some subatomic particles, invisible and untouchable effects of the very creation of reality, might exist simultaneously across all of space. We're honestly surprised people who say science is boring don't spontaneously combust from the foolishness of their statements.

"Relic" neutrinos, like the relic photons that make up the cosmic microwave background, are leftovers from the hot, dense early universe that prevailed 13.7 billion years ago. But over the lifetime of the cosmos, these relic neutrinos have been stretched out by the expansion of the universe, enlarging the range in which each neutrino can exist.

Of course there's a little bit of physics involved when you talk about particles pouring out of the beginning of time. Neutrinos are tiny, almost undetectable neutral particles which stream through pretty much everything, ever. Over one hundred trillion have passed through you while reading this sentence. Most of those came from nuclear reactions, but a blast wave of neutrinos were also released shortly after the big bang and are, we presume, still going strong.

"We're talking maybe up to roughly ten billion light-years" for each neutrino, said study co-author George Fuller of the University of California, San Diego. "That's nearly on the order of the size of the observable universe." These oldest of the subatomic particles might each encompass a space larger than thousands of galaxies, new simulations suggest.

While trying to calculate masses for neutrinos, Fuller and his student Chad Kishimoto found that, as the universe has expanded, the fabric of space-time has been tugging at ancient neutrinos, stretching the particles' ranges over vast distances.
Such large ranges can remain intact, the scientists suggest in the May 22 issue of Physical Review Letters, since neutrinos pass right through most of the universe's matter. The big question is whether gravity—say, the pull from an entire galaxy—can force a meganeutrino to collapse down to a single location.

"Quantum mechanics was intended to describe the universe on the smallest of scales, and now here we're talking about how it works on the largest scales in the universe," Kishimoto said. "We're talking about physics that hasn't been explored before."

According to physicist Adrian Lee at the University of California, Berkeley, who was not part of the study team, "gravity is a real frontier these days that we don't really understand. "These neutrinos could be a path to something deeper in our understanding with gravity."

Although they should be extraordinarily common in the universe, the relic neutrinos now have only about one ten-billionth of the energy of neutrinos generated by the sun. "This makes relic neutrinos near impossible to detect directly, at least with anything one could build on Earth," study co-author Fuller said.

Still, the fact that there are so many relic neutrinos means that together they likely exert a significant gravitational pull—"enough to be important for how the universe as a whole behaves," Fuller added. "So by looking at the growth of structures in the universe," Fuller said, "you might be able to detect relic neutrinos indirectly by their gravity."

The second part of this crash-course in cosmologically relevant physics is quantum theory. Particles can be "spread out" as a wavefunction - a representation of possible states - until they're observed and the wave collapses into a single fact. While that explanation is so horrifically simplified it would make a quantum scientists eyes bleed, it's good enough for now. The wavefunction of relic neutrinos from the big bang is on the length scale of the universe itself. They literally are sort of everywhere, because the only thing which can "observe" them is gigantic black holes or galaxies.

It's astonishing stuff, not just for the cosmo-experts but the casual fan. Because even trying to wrap your mind around...An ancient subatomic signature extends across the universe. It seems that some... more

Mammoth black holes push universe to its doom

THE mammoth black holes at the centre of most galaxies may be pushing the universe closer to its final fade-out. And it is all down to the raging disorder within those dark powerhouses.

Disorder is measured by a quantity called entropy, something which has been on the rise ever since the big bang. Chas Egan and Charles Lineweaver of the Australian National University in Canberra used the latest astrophysical data to calculate the total entropy of everything in the universe, from gas to gravitons. It turns out that supermassive black holes are by far the biggest contributors to the universe's entropy. Entropy reflects the number of possible arrangements of matter and energy in an object. The number of different configurations of matter a black hole could contain is staggering because its internal state is completely mysterious.

Egan and Lineweaver found that everything within the observable universe contains about 10104 units of entropy (joules per Kelvin), a factor of 10 to 1000 times higher than previous estimates that did not include some of the biggest known black holes (www.arxiv.org/abs/0909.3983, submitted to The Astrophysical Journal).

If entropy were ever to reach a maximum level, that would mean the heat death of the universe. In this scenario no energy can flow, because everything is the same temperature and so life and other processes become impossible. "Our results suggest we're a little further along that road than previously thought," Egan says.

But although black holes do boost the universe's total entropy, it is not clear whether they will hasten its heat death. Supermassive black holes don't contribute much to the flows of heat that even out temperature throughout the universe, says physicist Stephen Hsu at the University of Oregon in Eugene.

It's true that these black holes will slowly evaporate by releasing Hawking radiation, particles created near the boundary of the black hole. And this radiation could move the universe towards heat death.

Black holes may evaporate via Hawking radiation, tipping the universe towards its heat death. However, it will take some 10102 years for a supermassive black hole to evaporate. "The entropy inside those black holes is effectively locked up in there forever," Hsu says. So we may have reached a state approaching heat death long before, as stars burn out and their matter decays.THE mammoth black holes at the centre of most galaxies may be pushing the universe... more

Chapter : Maryam ( Mary )
From Verse 77 To Verse 98

Hast thou seen him who disbelieveth in Our revelations and saith: Assuredly I shall be given wealth and children? (77) Hath he perused the Unseen, or hath he made a pact with the Beneficent? (78) Nay, but We shall record that which he saith and prolong for him a span of torment. (79) And We shall inherit from him that whereof he spake, and he will come unto Us, alone (without his wealth and children). (80) And they have chosen (other) gods beside Allah that they may be a power for them. (81) Nay, but they will deny their worship of them, and become opponents unto them. (82) Seest thou not that We have set the devils on the disbelievers to confound them with confusion? (83) So make no haste against them (O Muhammad). We do but count out unto them a number (of days). (84) On the day when We shall gather the righteous unto the Beneficent, a goodly company. (85) And drive the guilty unto Hell, a weary herd, (86) They will have no power of intercession, save him who hath made a covenant with his Lord. (87) And they say: The Beneficent hath taken unto Himself a son. (88) Assuredly ye utter a disastrous thing (89) Whereby almost the heavens are torn, and the earth is split asunder and the mountains fall in ruins, (90) That ye ascribe unto the Beneficent a son, (91) When it is not meet for (the Majesty of) the Beneficent that He should choose a son. (92) There is none in the heavens and the earth but cometh unto the Beneficent as a slave. (93) Verily He knoweth them and numbereth them with (right) numbering. (94) And each one of them will come unto Him on the Day of Resurrection, alone. (95) Lo! those who believe and do good works, the Beneficent will appoint for them love. (96) And We make (this Scripture) easy in thy tongue, (O Muhammad) only that thou mayst bear good tidings therewith unto those who ward off (evil), and warn therewith the froward folk. (97) And how many a generation before them have We destroyed! Canst thou (Muhammad) see a single man of them, or hear from them the slightest sound?

The Day of Resurrection : Al-Haaqqa ( English Voice Translation )

Al-Haaqqa : Chapter 69

In the name of Allah, the Beneficent, the Merciful
The Reality! (1) What is the Reality? (2) Ah, what will convey unto thee what the reality is! (3) (The tribes of) Thamud and A'ad disbelieved in the judgment to come. (4) As for Thamud, they were destroyed by the lightning. (5) And as for A'ad, they were destroyed by a fierce roaring wind, (6) Which He imposed on them for seven long nights and eight long days so that thou mightest have seen men lying overthrown, as they were hollow trunks of palm-trees. (7) Canst thou (O Muhammad) see any remnant of them? (8) And Pharaoh and those before him, and the communities that were destroyed, brought error, (9) And they disobeyed the messenger of their Lord, therefor did He grip them with a tightening grip. (10) Lo! when the waters rose, We carried you upon the ship (11) That We might make it a memorial for you, and that remembering ears (that heard the story) might remember. (12) And when the trumpet shall sound one blast (13) And the earth with the mountains shall be lifted up and crushed with one crash, (14) Then, on that day will the Event befall. (15) And the heaven will split asunder, for that day it will be frail. (16) And the angels will be on the sides thereof, and eight will uphold the Throne of thy Lord that day, above them. (17) On that day ye will be exposed; not a secret of you will be hidden. (18) Then, as for him who is given his record in his right hand, he will say: Take, read my book! (19) Surely I knew that I should have to meet my reckoning. (20) Then he will be in blissful state (21) In a high Garden (22) Whereof the clusters are in easy reach. (23) (And it will be said unto those therein): Eat and drink at ease for that which ye sent on before you in past days. (24) But as for him who is given his record in his left hand, he will say: Oh, would that I had not been given my book (25) And knew not what my reckoning is! (26) Oh, would that it had been death! (27) My wealth hath not availed me, (28) My power hath gone from me. (29) (It will be said): Take him and fetter him (30) And then expose him to hell-fire (31) And then insert him in a chain whereof the length is seventy cubits. (32) Lo! He used not to believe in Allah the Tremendous, (33) And urged not on the feeding of the wretched. (34) Therefor hath he no lover here this day, (35) Nor any food save filth (36) Which none but sinners eat. (37) But nay! I swear by all that ye see (38) And all that ye see not (39) That it is indeed the speech of an illustrious messenger. (40) It is not poet's speech - little is it that ye believe! (41) Nor diviner's speech - little is it that ye remember! (42) It is a revelation from the Lord of the Worlds. (43) And if he had invented false sayings concerning Us, (44) We assuredly had taken him by the right hand (45) And then severed his life-artery, (46) And not one of you could have held Us off from him. (47) And lo! it is a warrant unto those who ward off (evil). (48) And lo! We know that some among you will deny (it). (49) And lo! it is indeed an anguish for the disbelievers. (50) And lo! it is absolute truth. (51) So glorify the name of thy Tremendous Lord. (52)Al-Haaqqa : Chapter 69 In the name of Allah, the Beneficent, the Merciful The... more
