A Step Forward Progress in Physics and Cosmology with an Alternative Approach to General Relativity
A property of spacetime which is the ability for more space to come into existence was first discovered by Albert Einstein with his General Theory of Relativity (GTR). This theory had predicted some observations like gravitational waves, black holes, orbital movements etc. Another property of spacetime is the fact that empty space can possess its own energy. As more space comes into existence, more of this energy of space appears, this form of energy regarded as dark energy would cause the universe to expand and accelerate at a fast rate. GTR had predicted some cosmological observations we see today but its still unable to account for the nature of dark energy, this has resulted into theorists insisting that there could be something wrong with GTR and a new theory could include a field that creates this cosmic acceleration. With a view that GTR has a way to account for the nature dark energy if traced back to the nature of spacetime just before cosmic inflation. I mainly review GTR and its subject equation. Also, with the view that all properties of spacetime are linked, I review major observatory points from LIGO project on gravitational waves, results from photometric observations of type Ia supernovae on the expansion of the universe. Finally, dark energy’s fellow; normal energy (Electromagnetic radiation, EMR) must not be left out from solving the puzzle and must take a review. I present a theoretical concept from GTR awaiting experimental prove. This concept accounts for the nature of dark energy arising from a non-stretched spacetime just before the cosmic inflation, relating the vacuum energy as true a property of the non-stretched spacetime which has an opposite effect as EMR. This concept emerging from GTR gives the experimentalists/cosmologists an idea on nature of dark energy.
