String Theory. It's simple in name, yet mind-boggling in nature.
Science does a great job of explaining what things are, how things work, and why things happen. However, string theory is the first theory of physics that tries to explain everything.
String theory is not proven, so it faces a lot of criticism. However, it is a very interesting theory that has great potential. This theory could help us answer questions such as - What is the purpose of a black hole? Are there other universes like ours?
A theory of everything could answer questions like these. So, let's take a look at what the theory is, what people say about it, and how it may affect future discoveries.
1. How It All Began
So, where did string theory start? It didn't start out as the theory we know today, it actually grew out of several other theories.
String theory started as an outgrowth of the S-matrix theory (particle physics) by Werner Heisenberg in 1943. Later, in the 1960s, the quark model was introduced. This is a model that explains fundamental particles (the really small stuff).
Then in 1968, after performing experiments with particle collision, physicist Gabriele Veneziano published his work on strings of energy that were noted during his experimentation. Taking all this past research on particle physics, fundamental particles, and strings of energy, several physicists began studies on string vibration and superstring theories.
2. What is String Theory?
Are there real strings in string theory and what are the strings made of?
Well, keep in mind this is all theoretical, but the answer is somewhat complex. String theory suggests that all particles at the subatomic level are flexible, vibrating strands or string of matter.
String theory belongs to the classification of quantum gravity and because string theory offers potential answers for a specification of gravity and the physics of particles, it just might be a potential theory that can answer all kinds of universally deep questions.
Albert Einstein searched for a theory that he could call the unified theory of everything. Unfortunately, despite all his great ideas, Einstein was never able to find the answer. String theory is viewed by some of its advocates as the answer to Albert Einstein's quest for a unified theory of everything.
The theory proposes that all subatomic particles that have been previously discovered are actually made of even smaller strings of fluctuating energy.
3. People that Like It
Could string theory unveil the unexplained mysteries of the universe?
Advocates are excited about the potential for advancing physics and particle science with string theory. Some supporters feel that one of the wonderful things about string theory is that it's both physical and calculating.
As noted in the section about how the string theory started, scientists over the years have been breaking matter down into smaller and smaller bits. Just when scientists think we have reached the end, string theorists break things down even more.
String theory just may be the next step in our developing perception of the universe. It could answer all the questions that until now were deemed crazy. Is time travel possible? Are there other parallel dimensions?
4. People That Don't Like It
Theories are never simple, and the string theory may be too complex to prove. The mathematical calculations involved in the string theory are incredibly wearisome and who has time for super long calculations? These two points alone are evidence enough for many critics that the theory is a waste of scientific effort and time. Critics dispute that after decades of effort, string theory hasn't produced any solid evidence to back up its claims. They are looking for physical evidence and actual results and string theorists just aren't there yet.
Many scientists and physicists feel that the theory is too good to be true. Critics complain after all the time and money spent exploring the theory and experimenting with the theory, there just aren't any results that show the results are worth the effort. In fact, some will claim that the theory is not as clear as it once was years ago.
5. The Future of String Theory
What can we expect from the string theory in the future?
Some versions of string theory predict tachyons. Tachyons are described as strings that travel faster than the speed of light. They are also predicted to move backward in time! Yes, this is the kind of information that science fiction authors love to hear and write about.
Black holes, origins of the universe, wormholes, and other futuristic ideas may not be impossible ideas with the string theory. With a basis in quantum physics and quantum gravity, string theory has the potential to further explain many of the unanswered questions of the universe we are part of.
