Space and time were created at the big bang. What was there before?
Was there something? Was there life? Was there nothing?
Luck was the reason our universe had more matter than anti-matter? Has luck become a respected scientific analysis? If it has, I can hold no trust in the hands of our scientists.
We only have an insignificant amount of knowledge of around 4% of what the universe is made of, the rest is known as ‘dark energy and dark matter’.
Can space and time be used to explain what created space and time? Can physics be used to prove physics? How do we prove mathematics is correct if we don’t have any implement to do so? Does mathematics hold the answer to everything? But what questions the mathematics?
We are caught in a cyclical trend where we make discoveries based on discoveries we have already made.
Is it really that imprudent to consider that a God exists? One who created and designed the universe?
Day after day we delve deeper and deeper into the theories of existence. Particles were considered to be little balls of matter; then they were discovered to have wave-like properties. We discover cells, then atoms, then protons, neutrons and electrons. Then quarks come to life, and now scientists are being led to believe that all the existence we see around us and all that we are made up of are little strings that stretch and wiggle and have different ‘flavors’ and ‘tunes’. Not to mention they are so miniscule that as Brian Greene mentions “If an atom was enlarged to the size of the solar system, a string would be the size of a tree on Earth.”
Far-fetched, or future?
To consider that the Sun was the centre of the solar system was a sacrilegious belief, far-fetched at the least. The Earth is flat and not round. Heavier objects have a higher acceleration than lighter objects.
So are we made of musical strings? Is life as we know it one big orchestra?
String Theory: A theory of elementary particles based on the idea that the fundamental entities are not point-like particles, but finite lines (strings) or closed loops formed by strings. The original idea was that an elementary particle was the result of a standing wave in a string.
A considerable amount of theoretical effort has been put into developing string theories. In particular, combining the idea of strings with that of supersymmetry leads to the idea of superstrings.
This theory may be a more useful route to a unified theory of fundamental interactions that quantum field theory because it probably avoids the infinities that arise when gravitational interactions are introduced into field theories. Thus, superstring theory inevitably leads to particles of spin 2, identified as gravitons. String theory also shows why particles violate parity conservation in weak interactions.
Superstring theories involve the idea of higher dimensional spaces: 10 dimensions for fermions and 26 dimensions for bosons. It has been suggested that there are the normal 4 space-time dimensions, with the extra dimensions being tightly ‘curled’ up.There is no direct experimental evidence for superstrings. They are thought to have a length of about 10^-35m and energies of 10^19GeV, which is well above the energy of any accelerator. An extension of the theory hypothesizes that the fundamental entities are not one-dimensional but two-dimensional, i.e they are supermembranes.
