Is there a definite age and size of the Universe? Some literary references state the Universe is around 13.7 to approximately 14 billion years old. This is appears to also be the age of the Big Bang ...
According to the theory of relativity, size or age of our observable universe can’t be determinate.
Here we go: If the speed of inflation after the Big Bang is close to light speed, time wouldn’t go fast. E.g. after a distance of the diameter of our galaxy with almost light speed, time could have past only 10 minutes. A lesser speed could cause the time to use up a million years. If you add to this problem the fact, that our 4 dimensions are born by this process, considering that all was spinning, no direct straight lines, zero time zones and – and – and, you can send all done calculations as “literary references” to the realm of phantasies.
One thing more I like us to consider: Big Bang theory is based on the redshift of light (Hubble). But this is based on the assumption that redshift is caused by the Doppler effect of light. But this is based on the assumption that space/time is void (and light is waved void). If you consider space/time NOT as void and energy as a certain condition of space/time, than the redshift could also be friction (or both, friction and Doppler effect of light). In this case, the Big Bang wouldn’t have to exist at all and all the believer of the Singularity (some final god creation) would have to start pursuing new again.
