End of Times! How Close Are We?
| Heat Death
Author Zahid Ikram
Cosmologists
estimate that the acceleration began roughly 5
billion years ago. Before that, it is thought that
the expansion was decelerating, due to the attractive
influence of dark matter and baryons. The density of dark
matter in an expanding universe decreases more quickly than
dark energy, and eventually the dark energy dominate.
Specifically, when the volume of the universe
doubles, the density of dark matter is halved but the
density of dark energy is nearly unchanged (it is
exactly constant in the case of a cosmological constant).

If the acceleration continues indefinitely, the
ultimate result will be that galaxies outside the local
super cluster will move beyond the cosmological horizon
(marks a limit to observability, and marks the
boundary of a region that an observer cannot see into
directly due to cosmological effects.): they will no
longer be visible, because their line-of-sight velocity
becomes greater than the speed of light. This is
not a violation of special relativity, and the effect cannot
be used to send a signal between them. (Actually there is no
way to even define "relative speed" in a curved space-time.
Relative speed and velocity can only be meaningfully defined
in flat space-time or in sufficiently small (infinitesimal)
regions of curved space-time). Rather, it prevents any
communication between them and the objects pass out of
contact. The Earth, the Milky Way and the Virgo Super
Cluster, however, would remain virtually undisturbed while
the rest of the universe recedes. In this scenario, the
local super cluster would ultimately suffer
heat death, just
as was thought for the flat, matter-dominated universe,
before measurements of cosmic acceleration.
سُوۡرَةُ الاٴنبیَاء
أَوَلَمۡ يَرَ ٱلَّذِينَ كَفَرُوٓاْ
أَنَّ ٱلسَّمَـٰوَٲتِ وَٱلۡأَرۡضَ ڪَانَتَا رَتۡقً۬ا
فَفَتَقۡنَـٰهُمَاۖ وَجَعَلۡنَا مِنَ ٱلۡمَآءِ كُلَّ شَىۡءٍ
حَىٍّۖ أَفَلَا يُؤۡمِنُونَ (٣٠)
خُلِقَ ٱلۡإِنسَـٰنُ
مِنۡ عَجَلٍ۬ۚ سَأُوْرِيكُمۡ ءَايَـٰتِى فَلَا
تَسۡتَعۡجِلُونِ (٣٧) وَيَقُولُونَ مَتَىٰ هَـٰذَا ٱلۡوَعۡدُ
إِن ڪُنتُمۡ صَـٰدِقِينَ (٣٨) لَوۡ يَعۡلَمُ ٱلَّذِينَ
كَفَرُواْ حِينَ لَا يَكُفُّونَ عَن وُجُوهِهِمُ ٱلنَّارَ
وَلَا عَن ظُهُورِهِمۡ وَلَا هُمۡ يُنصَرُونَ (٣٩) بَلۡ
تَأۡتِيهِم بَغۡتَةً۬ فَتَبۡهَتُہُمۡ فَلَا يَسۡتَطِيعُونَ
رَدَّهَا وَلَا هُمۡ يُنظَرُونَ (٤٠)
The Prophets 21: 30,
37-40
Have not those who disbelieve known that the
heavens and the earth were of one piece, then We parted
them, and we made every living thing of water? Will they not
then believe? (30)
Man is made of haste. I shall show you
My portents, but ask Me not to hasten. (37) And they say:
When will this promise (be fulfilled), if ye are truthful?
(38) If those who disbelieved but knew the time when they
will not be able to drive off the fire from their faces and
from their backs, and they will not be helped! (39) Nay, but
it will come upon them unawares so that it will stupefy
them, and they will be unable to repel it, neither will they
be reprieved. (40)
سورة الاٴنبیَاء
کیا کافروں نے نہیں دیکھا کہ آسمان
اور زمین دونوں ملے ہوئے تھے تو ہم نے جدا جدا کردیا۔ اور تمام
جاندار چیزیں ہم نے پانی سے بنائیں۔ پھر یہ لوگ ایمان کیوں
نہیں لاتے؟ (۳۰)
انسان (کچھ ایسا جلد باز ہے کہ گویا) جلد
بازی ہی سے بنایا گیا ہے۔ میں تم لوگوں کو عنقریب اپنی نشانیاں
دکھاؤں گا تو تم جلدی نہ کرو (۳۷) اور کہتے ہیں کہ اگر تم
سچے ہو تو (جس عذاب کا) یہ وعید (ہے وہ) کب (آئے گا)؟ (۳۸)
اے کاش کافر اس وقت کو جانیں جب وہ اپنے مونہوں پر سے (دوزخ
کی) آگ کو روک نہ سکیں گے اور نہ اپنی پیٹھوں پر سے اور نہ ان
کا کوئی مددگار ہوگا (۳۹) بلکہ قیامت ان پر ناگہاں آ واقع
ہوگی۔ اور ان کے ہوش کھو دے گی۔ پھر نہ تو وہ اس کو ہٹا سکیں
گے اور نہ ان کو مہلت دی جائے گی (۴۰)
