Q: 10. Prove from the current scientific knowledge that this universe obeys ALLAH?
Ans. According to Alan Guth’s Inflation theory in Physics, after the birth of universe, its size doubles every 10 ^-34 seconds. This doubling took place for not more than 10 ^-30 seconds.
Within this short time, universe expands from something you could hold in hand to something at least 10 ^ 25 times bigger.
In this extremely small interval of time gravity emerged, later on joined by strong and weak nuclear forces, later on joined by elementary particles. From nothing at all, suddenly there were a very large mass of electrons, protons, neutrons and much more.
ALLAH has said in Holy Qur’an:
The Originator of the heavens and earth. When He decides on something, He just says to it, ‘Be!’ and it is. (Surah Al-Baqarah, Surah # 2: Ayah # 117)
