Lasers drag tractor beams from sci-fi to sci-possible

A Week After The Invention of a Worlds First Anti laser,a device that absorbs, rather than emits,a beam of light.Scientists Have Successfully Demonstrated The Possibility of Tractor Beam In Future.
Tractor Beam is a Term Familiar To Those Who Are Fans of Science Fiction Movies Like Star Trek And Star War and Even In Austin Powers.
All Those Catchy intresting Concepts of Science Fiction Are more Likely To be Real soon Like Warp Effect,Anti laser ,Antimatter,Teleportation And Now the Star Trek Iconic Concept of Gravitational Beaming Of Objects "Tractor Beam"
Its Not A Thing To us ,Scientists are carrying out on this Things From Decaes And They Are Working on  Every Single of possibility of Turning of Our Science Fiction Things Into Reality .Tractor Beam is Very Famous For its Usage in Star Trek the starship Enterprise often dragged objects towards it with its glowing tractor beam.
Now There Is Every Possibility of Having This In Reality .But It May be Take a Decade To get into Play.

So What is A Tractor Beam And How It Drags The objects

A tractor beam is a device with the ability to attract one object to another from a distance. Since the 1990's, technology and research has labored to make it a reality, mostly at microscopic level. Less commonly, a similar beam that repels is called a pressor beam or repulsor beam. Gravity impulse and gravity propulsion beams are areas of research from fringe physics that coincide with the concepts of tractor and repulsor beams.

When light falls on an opaque object, the surface reflects most of the photons back in the direction they came from. What's less obvious is that these bouncing photons push back on the object, causing it to move away from the light source. If the object is very small, this push can be significant. But this is the exact opposite of the suction-like behaviour of tractor beams in science fiction.
Now Jun Chen of Fudan University in Shanghai, China, and colleagues, have shown that it is possible to create exotic beams that would pull rather than push on an object. For tiny particles with dimensions of a thousandth of a millimetre or so, this would result in the particle being drawn back towards the beam.


These Latest Advacnements Proves That The Future is Of "Lasers" And Likely To Live In The World Of Science Fiction  Movies.
