Considering that the oldest star yet found is 13.2 billion years old, our sun is approximately 4.57 billion years old.
Now, given the length of time it takes for a star to form, which is of course an approximation, figure the Galaxy is between 20 to 46 billion years old.
Now using the Drake equation, N = R* fp ne f l fi fc L
to determine the possibility of intelligent life in the galaxy, then the following conclusions can be reached.
Where: - R* is rate of formation of suitable stars (stars like the Sun) in the Milky Way galaxy
- fp is the fraction of those stars that have planets
- ne is the number of planets capable of sustaining life around each of those stars having planets
- fl is the fraction of planets capable of sustaining life that actually evolve life
- fi is the fraction of those planets where live has evolved that evolve intelligent life
- fc is the fraction of planets with intelligent life that develop the capability to communicate
- L is the fraction of the planet's life during which the intelligent life can communicate
Now, using some fairly conservative numbers, we then come up with:
- If we let fp = fl = fi = f c = 0.5 (middle of the road), then N = 2,500
- If we let fp = fl = fi = f c = 0.1 (one smallish side), then N = 20
- If we let fp = fl = fi = f c = 1 (their maximum), then N = 20,000
Which means there could be between 20 and 20,000 intelligent species in the galaxy.
Now, considering the average advancement time for civilizations to rise, using our own as a guide, and again, being conservative, that means there could be 2 to 400 races far more advanced than we are.
Now, while Einstein did say that the speed of light was finite, he also admitted the possibility of loop holes in that particular law of physics, found in his law of special relativity.
Hawking theorized that wormholes could link various points in the galaxy and the universe, or even parallel universes.
Which then brings us to the Mexican physicist Miguel Alcubierre, who proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand.
quote:
The ship would ride this wave inside a region known as a warp bubble of flat space. Since the ship is not moving within this bubble, but carried along as the region itself moves, conventional relativistic effects such as time dilation do not apply in the way they would in the case of a ship moving at high velocity through flat spacetime. Also, this method of travel does not actually involve moving faster than light in a local sense, since a light beam within the bubble would still always move faster than the ship; it is only "faster than light" in the sense that, thanks to the contraction of the space in front of it, the ship could reach its destination faster than a light beam restricted to travelling outside the warp bubble. Thus, the Alcubierre drive does not contradict the conventional claim that relativity forbids a slower-than-light object to accelerate to faster-than-light speeds. However, there are no known methods to create such a warp bubble in a region that does not already contain one, or to leave the bubble once inside it, so the Alcubierre drive remains a theoretical concept at this time.
Using the 3+1 formalism of general relativity, the spacetime is described by a foliation of space-like hypersurfaces of constant coordinate time t. The general form of the Alcubierre metric is: 
Now, with all that said, and taking into consideration the jokes already being thrown around by those who seem to be more than willing to believe that we are alone in the universe, I submit that we would be fools to believe that we are alone in the Universe.
I would also suggest that those who wish to joke and attack the beliefs of others read the Hindu Veda, the Piri Ries maps (which show Antarctica free of ice, and uses the geographic position of the Great Pyramid as the center, and finally, to duplicate the distortion, the reference altitude would have to be outside the atmosphere)
And when finished, please explain, using scientific proof how the Veda can discribe a nuclear war, as does the epic of Gilgamesh, as does various meso american cultures, and written 4000 years before the nuclear age, and finally, the various unexplained geologic locations around the planet which show evidence of considerable amount of heat, enough to make glass similiar to that near atomic test sites.
And when you can do that, and please remember, few accreditied physicists deny the possibility of intelligent races that can and have visited our worthless rock, convince them that it is all a bunch of mass psychosis with no possibility of ever happening.
Now, my personal opinion is that we have and are being visited, for observational reasons, in the hope that we as a race either grow up to a point where we no longer endeavor to destroy our own habitat and each other, or to know when they need to exterminate us to prevent us from spreading our insanity beyond our solar system.
