eh ada tambahan :
DILATASI WAKTU Pengertian dilatasi waktu ialah selang waktu yang dipengaruhi oleh gerak relatif kerangka (v).
Dt = Dto / Ö(1 - v²/c²)
Dto = selang waktu yang diamati pada kerangka diam (diukur dari kerangka bergerak)
Dt = selang waktu pada kerangka bergerak (diukur dari kerangka diam)
v = (v1 +v2) / (1 + v1 . v2/C²)
v = kecepatan benda
v1 = laju benda 1 terhadap bumi
v2 = laju benda 2 terhadap benda 1
v = laju benda 2 terhadap bumi
c = kecepatan cahaya
Artinya, karena malaikat dibuat Allah dari bahan cahaya, maka dia bisa melakukan pergerakan dengan kecepatan yang sangat tinggi mendekati kecepatan 300.000 km per detik. Nah, maka 'waktu' bagi malaikat akan mulur, yaitu sehari malaikat = 50 ribu tahun manusia! Dalam peristiwa ini, ternyata kecepatan malaikat ketika bergerak kepada Allah adalah sebesar 0,999 999 999 999 999 kecepatan cahaya.
Namun malaikat juga bisa memiliki 'waktu' yang berbeda-beda, dikarenakan kecepatannya bisa berubah-ubah sesuai kebutuhan. Hal ini dikatakan oleh Allah:
QS Fathiir (35) : 1
"Segala puji bagi Allah Pencipta langit dan bumi, Yang menjadikan malaikat sebagai utusan-utusan (untuk mengurus berbagai macam urusan) yang mempunyai sayap, masing-masing (ada yang) dua, tiga dan empat. Allah menambahkan pada ciptaan-Nya apa yang dikehendaki- Nya. Sesungguhnya Allah Maha Kuasa atas segala sesuatu."
Ayat di atas mengatakan bahwa malaikat memiliki kecepatan yang sangat bervariasi. Hal itu diumpamakan Allah dengan jumlah sayap. Bukankah sayap adalah alat untuk terbang dengan kecepatan tertentu?
Di ayat lain Allah mengatakan bahwa malaikat bergerak naik kepadaNya dalam waktu sehari yang kadarnya seribu tahun menurut perhitungan manusia. Maka di sini kita melihat, bahwa ternyata waktu itu bisa berubah-ubah kadarnya sesuai dengan kecepatan pelakunya.
QS. As Sajdah (32) : 5
"Dia mengatur urusan dari langit ke bumi, kemudian (urusan) itu naik kepadaNya dalam satu hari yang kadarnya adalah
seribu tahun menurut perhitunganmu"
Demikian pula pada saat hari kiamat. Allah mengatakan bahwa pada hari itu kadar waktu juga akan mengalami relativitas. Sehari pada waktu itu akan mulur sampai 1000 tahun waktu manusia sekarang.
Hal ini menunjukkan bahwa ketika terjadi kiamat itu, pergerakan benda-benda langit memiliki kecepatan yang sangat berbeda dengan sekarang. Kondisi saat itu adalah sedemikian rupa sehingga 1 hari pada waktu itu sama dengan 1000 tahun sekarang. Itulah saat saat terjadinya kiamat.

<nugraha212@gmail.com> Hanya sekedar ingin berbagi artikel. Saya tertarik setelah membacanya, dan baru tahu (kalau berpedoman pada artikel ini) kalau metode lubang cacing ini pernah dilakukan oleh Nabi Muhammad (ketika melakukan Isra Mi'raj yang hanya dilakukan dalam waktu satu malam), padahal biasanya wormhole ini sering digunakan oleh malaikat ketika akan naik ke langit yang dalam Al-Qur'an diceritakan bahwa malaikat itu naik ke langit memerlukan waktu 1 hari yang bagi manusia setara dengan 50 ribu tahun
[22.47] Sesungguhnya sehari di sisi Tuhanmu adalah seperti seribu tahun menurut perhitunganmu.
[70.4] Malaikat-malaikat dan Jibril naik (menghadap) kepada Tuhan dalam sehari yang kadarnya lima puluh ribu tahun.
Wallohu a'lam bishshowab

Wormholes (معارج)
Naturally occurring wormholes connect distant black holes.
Look up to the night sky and select a star as a destination. Can any human reach this star by just walking few steps?
General relativity explained a mechanism to contract this huge distance into few meters. Albert Einstein called this mechanism 'bridges' in space-time. Today, scientists call them wormholes. A wormhole would act as a shortcut connecting two distant regions in the universe.
A wormhole contracts the distance between two doorways placed separately anywhere in the universe. Example, consider a galaxy 100 million light years away. When you look today from Earth to that galaxy, you will not see it as it is today, but rather as it was 100 million years ago. This is because light took 100 million years to travel all that distance. But if you take a journey inside a wormhole from Earth to that galaxy, you would reach that galaxy today. So when you reach it today, you will see it as it is today, not as it was 100 million years ago. So if you use a wormhole, events at that galaxy (your destination) would appear as if in fast forward (from 100 million years ago till today).
When you reach that galaxy today and look back at Earth, you would not see Earth as it is today; instead you would see Earth as it was 100 million years ago (you would see the dinosaurs). This is because light took 100 million years to reach there. So as you use a wormhole, events at Earth (your departure) would appear as if in fast rewind (from today till 100 million years ago).
On the return journey, events on Earth (destination) would appear as if in fast forward (from 100 million years ago till today); while the events at that galaxy (departure) would appear as if in fast rewind (from today till 100 million years ago). This is not time travel; this is just a consequence of the length contraction inside a wormhole.
Scientists know how a wormhole works but have never actually used one. Do you remember how a frictionless roller coaster works? That is, you start high and slow then you go down and fast but when you come back up again to the previous height you return to your previous slow speed? Well, the wormhole is the most efficient roller coaster you can imagine. Energy is not required to move through the wormhole, that is, you can simply switch off your rockets. Gravity accelerates you and pulls you through and then expels you the other side. You will feel like being swept by waves at the beach; nothing more.
On your way through, gravity causes your clock to run slower and your ruler to shrink. Distant observers see you accelerating to relativistic speeds; as a result, your energy (and mass) increase dramatically in their view; but when you get out the other side everything returns back to normal (your clock, ruler...).
God gave this method of transportation to his angels throughout the universe. The Quran calls them 'Ma'arej معارج' and describes how angels use them for long distance travel. Today Moslems know that these 'Ma'arej' is what scientists call wormholes:
[Quran 70.1-4] Someone asked about the penalty that will befall 2 the unbelievers; (A penalty) that has none to ward off; 3 (a penalty) from Allah (who owns) wormholes [Ma'arej in Arabic] 4 The angels and the Spirit ascend to Him in a day, the measure of which is fifty thousand years.
Any object passing through this wormhole will also experience this same time dilation (one day inside wormhole vs. 50,000 years on Earth) and not just those angels. This time dilation does not say how long it takes you to cross the wormhole, it just says that when you pass through the wormhole you age by this ratio. This space is called hyperspace (برزخ).
God says that those wormholes are doors in the heaven that contract interstellar distances into walking distances; the resulting scenery is bizarre: God says that those who do not believe in the message will not believe it even if He showed them a bigger sign. He created beautiful towering structures in the heavens. If He opens for those nonbelievers a door in heaven and lets them continue passing through it to those distant structures, they would not believe that they really got there by simply walking few steps. Instead they would think that they are just optical illusions:
[Quran 15.13-16] They do not believe the Message, like those who preceded them; 14 Even if We [Allah] opened upon them from the heaven a door and they continued passing through it 15 they would say 'Our sight is bedazzled, rather we have been bewitched' 16 It is We [Allah] who have made towering structures in the heavens and made them beautiful for beholders. 17 And We protected them from every evil spirit accursed.
Here, they wouldn't believe their own eyes thinking that what they see is not real. They wouldn't believe that they got to those heavenly structures by simply walking few steps. But God insists that what they see is real and not illusions (that is, they really got there).
The Quran says that those heavenly doors are galactic shortcuts to distant places in the universe. Angels guard those heavenly doors 'from every evil spirit accursed'. Moslems believe that angels use these doors for long distance travel. Angels can accelerate up to the speed of light for domestic travel; but they use these wormholes to reach any place in the universe before you finish reading this sentence.
Moslems also believe that wormholes are not strictly for the use of angels. Their prophet used a wormhole once in the 'Israa & Me'raj' (Me'raj معراج is singular of Ma'arej) (Quran 17.1).
See: The Quran describes the doorways of a wormhole like two shells, exactly like modern science: Islam & Life on other Planets.
[Quran 34.6] On the day when We will fold the heaven, like the folder compacts the books, and as We originated the first creation We shall return it; a promise (binding on Us); surely We will deliver. .
Here God promises to make the Big Crunch not by gravity but rather by folding the Heavens like a book, that is, by the same mechanism He controls wormholes. This means that this Big Crunch can begin and end in a fraction of a second!
You might question how could this Big Crunch happen in just a fraction of a second? Wouldn't that be faster than the speed of light? Isn't that a contradiction with special relativity which says that nothing can go faster than the speed of light? Well yes it is faster than the speed of light, but the Big Bang itself turned out to be faster than the speed of light! The Big Bang started from a cosmic singularity and then expanded much faster than speed of light. During the Big Bang a process called "INFLATION" occurred. A fraction of a second (10-38 sec) after the cosmic singularity was created inflation started. During inflation, the size of the entire universe increased from an initial size smaller than the size of an atomic nucleus (10-23 millimeters in diameter) to maybe the size of our galaxy (one hundred thousand light years across). The duration of this inflation was only a fraction of a second (10-35 sec). So the Big Bang itself was a zillion times faster than the speed of light. This is not a contradiction with special relativity because spacetime itself expanded. In God's promise of the Big Crunch spacetime itself will contract, that is, it is inflation but in reverse.
Our observable universe (the one we can detect with today's equipment) consists roughly of 100 billion galaxies with each galaxy consisting of about 100 billion stars. (Number of observable stars = 100bln x 100bln; that's one with 22 zeroes next to it). If you can count 23,000 stars per second you will need more than 13 billion years to finish counting!!! This observable universe is just a fraction of the entire universe. After this Big Crunch is over the entire universe would be squeezed into a space smaller than the size of an atomic nucleus; just as it all started in the Big Bang.
[Quran 34.6] And those who have received knowledge (scientists) will see that what have been sent down to you from your Lord (the Quran) is the Truth, and that it guides to the Path of the Exalted, Worthy of all praise.
Moslems ask how could an illiterate man who lived 1400 years ago have figured out Length Contraction and Wormholes?
