Quran
36/40) وَكُلٌّ فِى فَلَكٍ يَسْبَحُونَ
It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming.
THERE ARE 2 REASONS
A
1-Allah SWT chose to use the arabic word “yasbahoon” to describe the movement of celestial bodies ,(moon sun planets) in outer space.
2-“Yasbahoon” means to swim
3-Why would Allah SWT choose this word? – A possible explanation is that the verse indirectly refers to the universe behaving like a fluid
4-Scientists consider the universe to be like a fluid (AND YOU CAN ONLY SWIM IN A FLUID)
All of cosmology assumes the presence of cosmic fluids (matter, radiation, dark matter, dark energy, etc) in the universe.
5-Astronomers attempt to mimic hydrodynamic (fluid)equations to cosmology and regard the content of the universe to be like a fluid.
6-Scientists propose that there is a similarity between hydrodynamic (fluid) equations and cosmological equations
7-When studying the large scale structures of the universe galaxies are considered to be like a particle in a fluid.
B
1-The sun, moon , all celestial bodies all swim, each in an orbit.
2-All celestial bodies move in an orbit and they all rotate on their own axis while doing so.
3-The sun rotates on its own axis as it moves in its orbit around the centre of the milky way and the moon rotates on its own axis as it revolves around the earth. The earth rotates on its own axis as it moves around the sun causing night and day.
4-The quran mentions that celestial bodies move in an orbit.
5-The word “yasbahoon” is translated as swim. If the word is used for movement on land it would imply that the person is running (thereby moving the arms and legs) and not riding (ie.arms and legs are not moving ). If it is used to describe movement in water it, would imply the person is swimming (moving legs and arms) not floating (i.e. not moving his/her body).If the word “yasbahoon” is used to describe the movement of a celestial body, then it would be correct to assume the celestial body is rotating on its axis as it is moving in an orbit
