The original picture of the rock under the golden Dome of the Rock (Quba al Shahra)

This is the picture of the rock that is believed to be the standing point when the Prophet Muhammad about to ascend to heaven in the event of Israk Mikraj. It is located in the infamous Dome of the Rock, in Jerusalem, one of the famous landmark of the Palestine. Is this rock actually floating? Honestly, i do not know the answer. But this is a very famous place and many pilgrims visited it every day, they should have known it if it is floating in the air.

Concluding remark

I hope this is enough to prove that the so-called 'floating rock' - and the miracle story that accompany it - is not true. For fellow muslims, I just want to say that we should not hurryly believe pictures or stories that is attributed to be the miracle of Allah, or Islam. We can still be a believing muslim, even if we do not believe such 'miracle pictures'.
That rock is nothing compared to the Power of Allah.
