Parbat said:Big bang suggests that there was only a concentrated mass.was there no space?If there was no space where did it come from?[i mean what makes space?].time also started after big bang.how did it start?
Don't u guys think there's somethin missing in this theory?
Chronos said:The holy grail of physics [at present] is to unite general relativity with quantum mechanics - quite a challenge. I think both theories are good approximations, but, incomplete. Until we figure out the incomplete parts, unification is not possible.
In my opinion the key to dealing with the current cosmological problems require applying some of the ancient spiritual Philosophies like buddhism.
As I understand the big bang:
Nothing can travel faster than light. Light travels at 2.998E^8m/s. The universe is accelerating at an increasing rate.
Paradox number 1: the big bang was expanding extremely fast at the very beginning and its rate slowed. If this is true, how can the universe now be expanding at an accelerating rate?
Just how fast was the universe expanding in the beginning? How fast is it expanding right now? Will its rate of expansion be limited by the speed of light? Is there any evidence that the rate of expansion at the beginning was greater than the speed of light? How do these questions fit in with the non-synthesizing qualities of General Relativity and Quantum Mechanics? What would Einstein say?
Time slows down as you approach the speed of light. If I understand it right, the relationship between the speed of light and time is an inverse relationship. That is, the faster something goes, the slower the time passes for it. Is there a simple graph that shows this relationship? Is it linear, quadratic, exponential or something else?
Since light is always traveling at the speed of light then we can conclude that it is ageless? That is, light... all light... is still as young as the point of its creation at the Big Bang?
How does light travel if time never passes for it? Isn't change and thus movement a function of the time/space continuum? Don't you need the passage of time for change to take place? But time does not pass for light, so how can light travel? let alone at some specified constant in space and time? Light is in space, but is it in time? Is it not timeless and ageless?
In Buddhism and other enlightenment philosophies, the goal is to escape the physical world and become "One" (with the universe) in a state of bliss where there is no time and space--sort of analogous to becoming light. Does it make sense to consider ancient spiritual philosophies when trying to come up with a better understanding of the gestation of the universe and what was 'before' the big bang? Does it make sense to consider such philosophies in trying to unify Quantum Mechanics and General Relativity?
What other implications are there for the fact that light is always traveling at the speed of light and thus time is never passing for it? Again, can I accurately state: light exists in space, but not in time?
