Most of you, who are old enough to read this article will be familiar with gravity and some of you will understand quantum mechanics. In simple words, gravity deals with the big objects and quantum mechanics deals with those really small ones. Both theories go a long way in explaining the intricate web that is our universe.

### The Big Question

The biggest question faced by theoretical physicists as per Dr. Stephen Hawking is “to find a theory which can explain every phenomena in the universe with a simple, elegant equation”. This means finding something that can combine these two polar theories. String theory is one such proposition that has the potential to be the Ultimate Theory. It states that there are 6 other dimensions than the normal 4 (3-D + the 4th one that is time). It also purports that these alternate dimensions are what controls the vibration of subatomic particles. This theory can be expanded to explain how gravity and quantum mechanics can fit together.

The challenge however is to take this out of mathematical models, which till now was the only way these can be explained. That is all changing thanks to VR. Step in to the light which is a firm in lower east of Manhattan is using VR to explain these complex concepts better than ever done before. They create complex multidimensional objects such as a tesseract, which takes shape by combining multiple cubes in to one. This creates the tesseract with 24 square faces, 16 vertices and 8 connected cubes that spans the entirety of the 4 dimensions.

### The creepy world of particles

“Having these complex shapes floating around you and being able to manipulate them freely gives a whole new perspective to the study of String theory” says Brian Greene. He is a physicist at Columbia university and a best selling science author. String theory is his specialty and he is all in on the possibilities VR brings to the table. He demonstrates the basic idea of the theory by showing a line which looks *mmm* like a line. He then zooms in real close to show that an ant is walking through the edges of that line. The takeaway being that, these dimensions remain invisible until you can view them at the right size. All this is done using an HTC Vive headset.

He briefly goes on about the eerily weird structures named Calabi-Yau manifolds. They are usually at the smallest meeting points imaginable in reality. These things till now has been mathematical models that has never been viewable before.

He is excited about the new frontiers that VR will bring in to theoretical physics. The idea of visualizing something just after theorizing it is truly revolutionary. We are now the closest that we have ever been to solving this problem. Hawking said that this theory won’t come to fruition in his lifetime, Hope VR proves him wrong.
