Although many scientists have verbally denied God, yet through their scientific work they have always remained faithful to their creator God. I will give a few examples here.
1) God is said to be immaterial. This means God contains no matter. As matter and energy are equivalent, so we can say that God contains no energy. So total energy of God is zero. God is the source from which everything has originated. If the source does not contain any energy, then the outcome – here, the universe – cannot contain any energy. That means the total energy of the universe cannot be other than zero. Remaining faithful to their creator God scientists have also shown that the total energy of the universe is indeed zero.
2) God is also said to be spaceless and timeless. If God is really there, then there will be the presence of an everlasting state of spacelessness and timelessness in addition to the universe, because this God is everlastingly present with all his attributes. Due to the presence of this everlasting state of spacelessness and timelessness in addition to our universe space and time in our universe cannot be absolute. For space and time to be absolute, they will have to have the same values in each and every case without any single exception. But due to the presence of this everlasting state space and time will have null values in at least one case, that is, in case of God, whereas in every other case they can have non-zero values. Thus it can be seen that due to the presence of this everlasting state of spacelessness and timelessness in addition to our universe space and time in our universe will fail to have the same values in each and every case, which they must have if they are to be absolute. So in this situation it is impossible for space and time to be absolute. Here also remaining faithful to their creator God scientists have shown that space and time are not at all absolute.
3) God is said to be timeless. Remaining again faithful to the creator God Einstein has shown how a timeless state can obtain. Special theory of relativity (STR) has shown that at the speed of light time totally stops.
4) God is said to be spaceless. In this case also Einstein remained faithful to the creator God and has shown how a spaceless state can obtain. STR has shown that travel distance becomes zero for light. If certain amount of space (say, a room) is filled up with light only, then the volume of that room will be zero due to this property of light. As zero volume means no space, so in this way a spaceless state can obtain.
In all the four cases above scientists could have shown just the opposite than what they have actually shown, thus falsifying God. Just show that the universe as a whole has non-zero energy value, God will be falsified. Or show that it is in no way possible to be spaceless and timeless, again God will be falsified. Or show that space and time are not relative, but absolute and God will be falsified. Any one of these shown by them could have falsified God for all time to come. And they were always free to falsify him. But despite that they have failed to do so. This is solely because as scientists it is not their job to manufacture truth, but to discover it. So it was not at all possible for them to do otherwise than what they had actually done, even if they had wanted to.
