This is a very old article circulated repeatedly on the internet. Time travel at the moment is not possible in the hand of science. Logically speaking, if you are turning back time you are also turning back the events so if you are 30 years old and travel back 10 years you will reach the era where you were 20 years old. It would be impossible for your duplicate to exist if you travel back in time. So one can only travel as far as his age dimension permits. Obviously you don't want to travel to the point where you will separate into a sperm cell and ovule.
There was a popular movie serial made on this phenomenon by Film Australia between 1991-1993:
Girl from Tomorrow

Girl from Tommrrow Part Two: Tomorrows End.

REMEMBER, at the time of prophet, there were no Formulas to quantify the time as a physical and measurable dimension, there was no such thing as measuring time and quantifying the Dimension of Time as we know it.
Who ever wrote this article wasn't one of the brightest student of scientific history. Time has been measured since 3500BC using a solar clock aka sun dial.
Wikipedia:
Sundials in the form of obelisks (3500 BC) and shadow clocks (1500 BC) are known from ancient Egypt, and were developed further by other cultures, including the Chinese, Greek[1], and Roman cultures. A type of sundial without a gnomon is described in the Old Testament (Isaiah 38:8).(ca.700 BC).

Now we know, that TIME travel is possible, and if we are to try to REACH another GALAXY, in our own Universe, we must travel at the SPEED OF LIGHT or faster. Or in other words, the TIME will NOT move, when we leave and come back.
At school we have a ridiculous guy propagating the similar views and article. Scientifically speaking the materials needed to travel at the speed of light isn't close fetched and even if materials were miraculous discovered there would be consideration for fuel, propulsion and waste heat. Scientist struggle with over heating space shuttles entering earth atmosphere and here we are talking about 300,000M/s velocity.
The night of Miraj was definitely Allah's miracle however miracles are not disclosed by science hence the reason they are classified as miracles. But one doesn't know if he really traveled at speed of light or not because Allah as the supreme creator can make anything stop including time and revolution of earth.
