Well, explanations will be given depending on the ignorance of the audience.
You will need very simple explanations. We'll bear it in mind.

Virtual world is not everything. Not even a miniscule of the world is represented in the computer world. Even if the Google Earth manages to show the details of the brick work of your home, it wouldn't be able to show what is there in your bed room or bath room. It goes on---
When electromagnetic radiation can get affected by gravity, why not the atomic clocks?
Though Einstein’s theory of general relativity proved Newton wrong, Newton’s theory still holds true in the vast majority of situations. Einstein’s theory helped us understand the universe better and helped us move forward in Science. But this wouldn’t have been possible without the Newton’s theory.
If we insist that Einstein’s theory is the ultimate and nothing beyond to think, out of our love and attachment to this great personality, then science becomes a religion.
An atomic clock would run slower on the top of Mount Everest than at sea level. They are affected by gravity. Do you know anything about this subject?

This is true, and no-one here is arguing that Einstein's theories are some kind of untouchable absolute. Even now, there are debates around recent findings in CERN. The criticism you're receiving is because your thought experiments are illogical and based on a poor understanding of fairly basic physics.
It must be the other way- clocks run slower at sea level than on the top of Mount Everest.
That's what is my whole point here- clocks get affected by gravity.
They measure different times not because the Time itself is getting dilated or contracted but due to the fact that clocks get affected by gravity.
(Weighing machines measure differently on Earth and Moon for the same Mass, not because the Mass itself is altered but because they get affected by the gravity.
I will try to correct myself if you would kindly specify why it is illogical?
You are correct,a momentary lapse of reason caused by watching QI while posting. Multi tasking is not my strong point. We are in agreement about the effect of gravity on clocks. This has been known for a long time. Nothing new there.
If time dilation was true 1.If there was no absolute time, certain things make no sense- velocity, acceleration, frequency etc.
2.Twins paradox
a.Due to the expanding universe, we on this earth are already moving at close to the speed of light relative to the receding galaxies at the ‘far end’ of our universe. This should make us immortal!
b.Coming to the twins paradox, it is said that if one of the twins travels to the outer space at close to the speed of light, on his return from the space trip, because of time dilation, he would apparently be younger than his earth bound twin. But we could argue that the earth bound twin was also moving at the same speed relative to the space bound twin. So time should dilate for both them equally.
c.As motion is a relative thing in this universe, the concept of time dilation for fast moving things is rather absurd.
3.If time runs slowly near strong gravitational fields, it must have run increasingly slowly as we trace back our expanding universe to the point of big bang.
a.As time runs infinitely slowly as we approach the big bang singularity, we would never ‘reach’ the stage of singularity, if at all this existed.
b.Or at least the predicted time scale of events since big bang are totally wrong – one billionth of a second immediately after the big bang could well be equivalent to our 13.5 billion years, which is the estimated age of our universe!
4.Earth older than Sun?
a.As time should run slower for the Sun than for the Earth, at some point of time, it is possible that our Earth gets older than the Sun and similarly our moon older than our earth.
b.Also we are probably looking at the sun that is actually in our past and the moon which is in our future! So time travel is possible!
May be that weirdness of weirdness leads us to the reality and this is what mathematicians and scientists are hoping for! (Like negative value multiplied by another negative giving a positive value)
And? Are you groping your way to finally making a point?

Well that's known for a long time, but Relativity attributes this to lack of absolute time.
I think his knowledge is homeopathic.
Really? Could you please point out where GR states this, together with the maths? Give me your alternative explanation,together with the maths.
That's a pretty basic stuff in special and general relativity. If you google, you can find plenty of information on that along with the maths.
I hope now you realise that the 'homeopathic knowledge' is very powerful and specific.
‘Fecilitate’ doesn’t mean superior or better.
A blatant dodge. I was asking about your alternative explanation. You appear to think that there is something wrong with GR. If you can't do the maths, just say so.

I'd like to know the source of your arrogance. Seriously, you have no real grasp about the subject matter, let alone enough to propose a thought experiment.
Fascinating.
