Abstract
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.
Highlights
Physics and cosmology welcome the idea that more space can come into existence by expansion
The summary of the 691 illustration implies that the elastic rubber is stretched or expanded, there was a default length and thickness of the elastic rubber just before it was stretched. Using this illustration in cosmology, the universe is expanding which means the distance between two points will increase over time, the elastic rubber in this case is spacetime
There is a default nature of spacetime that was present just before cosmic inflation, the fact that dark energy had driven the expansion of spacetime right from the big bang means that the nature of dark energy can be described if that default nature of spacetime is presented
Summary
Physics and cosmology welcome the idea that more space can come into existence by expansion. Hubble space telescope observations of very distant supernovae showed that a long time ago, the universe was expanding slowly than its rate today. The nature of spacetime at the outer-space is observed to be very thick and a better illustration of its expansion is like the expansion of an elastic rubber, if two points are marked apart on an elastic rubber, the distance between the two points increases by stretching. A view that EMR will provide a huge lead to dark energy is presented in Section 4 and 4.1.
