This idea is about 2 minutes long.

String theory is probably one of the wildest theories that has ever come out of science.

But to verify any theory, we need to design and run experiments. At the beginning of modern science in the 17th Century, a person like Galileo could build their own instruments by hand and discover new things about the universe.

He discovered that the moons of Jupiter orbited the planet, which led to the acceptance of the theory that the Sun was at the centre of the solar system.

But as science has advanced, and the deeper and further that we have peered into the universe, the more sophisticated equipment we’ve had to build.

At the cutting edge of current science is the Large Hadron Collider, or LHC. It’s a facility so expensive (at $4.75 billion USD to build and $1 billion per year in running costs) that it requires the collaboration and funding from 100+ countries to keep it running.

One of the smallest subatomic particles that it can detect are something called called quarks, which have been pivotal in verifying quantum mechanics, the world inside the proton and neutron.

Enter string theory.

It predicts that deep within quarks are tiny, vibrating strings. They are so tiny that if a quark was blown up to the size of the sun, a string would be smaller than a human hair on its surface.

You can barely see the Earth next to the sun, let alone a human hair.

We need to be able to measure strings with our instruments in order for string theory to be confirmed. The colossal distance between the smallest thing that we can measure right now and a string is why we aren’t even close.

If we were to use the same technology that the LHC is based on, we would to build a particle accelerator the size of the galaxy to be able to see strings. Clearly, we need a different approach.

Fortunately, there may be a way.

When the Big Bang created the universe, it expanded rapidly from an infinitesimally tiny point into the gigantic universe we see today.

Some scientists think that at some point along the way, just fraction of a second after the Big Bang, the universe must have been about the size of a string.

So it’s possible that we will find ‘shadows’ of strings in the overall shape of the universe. We may be able to build a telescope powerful enough to see them.

If string theory is confirmed, we must be prepared for some startling revelations that come from peering so deep into the fabric of reality.

The theory predicts that we must be living in a universe that contains at least 10 dimensions, which may mean that our universe is just one of many, layered on top of each other like the pages of a closed book.
