Why is it so surprising that light affects heavy molecules?
All it got to do is to affect individual particle or molecule and cause them to rotate slightly, in effect each one of them rotating in a chain and then you have the string twist.
While light has been known to affect matter on the molecular scale—bending or twisting molecules a few nanometers in size—it has not been observed causing such drastic mechanical twisting to larger particles. The nanoparticle ribbons in this study were between one and four micrometers long. A micrometer is one-millionth of a meter.
“I didn’t believe it at the beginning,” Kotov says. “To be honest, it took us three and a half years to really figure out how photons of light can lead to such a remarkable change in rigid structures a thousand times bigger than molecules.”
Sudhanshu Srivastava, a postdoctoral researcher in his lab, is trying to make the spirals rotate. “He’s making very small propellers to move through fluid—nanoscale submarines, if you will,” Kotov explains. “You often see this motif of twisted structures in mobility organs of bacteria and cells.”
The nanoscale submarines could conceivably be used for drug-delivery and in microfluidic systems that mimic the body for experiments. This newly discovered twisting effect could also lead to microelectromechanical systems that are controlled by light. And it could be utilized in lithography, or microchip production.

Light does not have mass -- light has MOMENTUM. It's a subtle but important difference.
To measure anything’s position precisely, at any given instant, is to “lock-in” on one static frame of its motion, as in a film. Conversely, as soon as you observe movement or momentum you can’t isolate a frame — because momentum is the summation of many frames. Sharpness in one parameter induces blurriness in the other. To understand this, consider for a moment that you are watching a film of an archery tournament. An archer shoots and the arrow flies. The camera follows the arrow’s trajectory from the archer’s bow toward the target. Suddenly the projector stops on a single frame of a stilled arrow. You stare at the image of an arrow in mid-flight, something you obviously could not do at a real tournament. The pause in the film enables you to know the position of the arrow with great accuracy — it’s just beyond the grandstand, 20 feet above the ground. But you have lost all information about its momentum. It is going nowhere; its velocity is zero. Its path, its trajectory, is no longer known. It is uncertain. It soon becomes apparent that such uncertainty is actually built into the fabric of reality. This makes perfect sense from a biocentric perspective: Time is the animal sense that animates events — the still frames — of the spatial world. Everything you perceive — even this page — is actively and repeatedly being reconstructed inside your head in an organized whirl of information. Time can be defined as the summation of spatial states; the same thing measured with our scientific instruments is called momentum. The weaving together of these frames occurs in the mind. So what’s real? We confront a here-and-now. If the next “image” is different from the last, then it is different, period. We can award that change with the word “time” but that doesn’t mean there’s an actual invisible entity that forms a matrix or grid in which changes occur. That’s just our own way of making sense of things, our tool of perception. We watch our loved ones age and die, and assume an external entity called time is responsible for the crime.
Leedskalnin's workshop also contained chains, blocks and tackle and other items that one might find lying around a junkyard. Some items are missing, though. Photographs of Leedskalnin at work show three tripods, made of telephone poles, that have boxes attached to the top.

Try out this model for the coral castle construction -- works for me:

(Like I have said many times) You can use light to make a time machine. The real question is how. But ,fortunately for me, nobody knows. RATHER than me of course.

You can not use a massless particle/wave of energy to travel backwards in time. Scientists are already starting to understand that time as a fourth dimension is just hogwash. If one wants to time travel, then one needs to reverse entropy for the entire universe.
Good luck.
