In his famous general theory of relativity, Albert Einstein turned physics on its head. He showed that physics is not intuitive and common-sense assumptions no longer work. He demonstrated that the concept of space and the concept of time are integrated.
 
Relative to an observer space stretches and time moves slower as it approaches the speed of light. He established that nothing can exceed the speed of light, which is 670 million miles per hour (186,000 miles sec). And a decade on in his Theory of General Relativity he further described gravity as the warping of space-time and the existence of black holes.
 
We know now that there are fewer atoms in the universe than we would suppose, and most of them - the most common of them are hydrogen and we are mostly composed of hydrogen. We don't know much about the rest, the dark matter and dark energy and cannot detect them directly, but they have noticeable effects on energy and matter.
 
It is postulated that dark energy is the mysterious force that no one completely understands with any degree of certitude but is the source of the energy which is causing the universe to expand or stretch faster and faster.
 
"Frankly, we just dont understand it," says Craig Hogan, an astronomer at the University of Washington at Seattle. "We know what its effects are," Hogan says, but as to the details of dark energy, "Were completely clueless about that. And everybodys clueless about it." (Andrew Chaikin, editor of Space & Science, Jan 15, 2002)
 
Dark energy was discovered in 1998 during a survey of supernovas in distant galaxies. The supernovas were dimmer than what was expected indicating that they were further away than expected. Cosmic Microwave Background (CMB) radiation has confirmed the universe to be 13.7 billion years old. The survey of exploding stars or supernova seemed to indicate that a mysterious repulsive force as been noticeably affecting the gravitational force galaxies exert on each other since about 5 billion years ago.
 
The expansion of the universe in the form of a "negative pressure" was first proposed by Einstein in the theory of general relativity.
 
"If you think in terms of the universe as a very large balloon," she says, "when the balloon expands, that makes the local density of the [dark energy] smaller, and so the balloon expands some more . because it exerts negative pressure. While its inside the balloon its trying to pull the balloon back together again, and the lower the density of it there is, the less it can pull back, and the more it expands. This is what happens in the expanding universe." (Virginia Trimble of the University of Southern California at Irvine - Space & Science, Jan 15, 2002)
 
We live in a multidimensional universe - perhaps a multiverse of universes. "Like quarks or dark matter and dark energy, whose existence we only indirectly ascertain, extra dimensions will not appear to us directly. Nonetheless, signatures of extra dimensions, even when indirect, could ultimately reveal their existence." (Warped Passages, Unraveling the Mysteries of the Universe's Hidden Dimensions - Lisa Randall - Harper 2006)
 
Time also has no absolute meaning except as a measure of change. In space there is no time. Time is only relative to the observer. We age, therefore we are aware of our chronology because it is relative to how we change.
 
If there is no air resistance we are ALSO not aware of our falling. All bodies are in free fall along warps and curves in space. The moon is falling around the Earth and the Earth is falling around the Sun. And in a spacecraft we think we are flying but when we are orbiting the earth we are not aware of our falling around the earth. Falling is not an observable phenomena.
 
"Neither space nor time has any existence outside the system of evolving relationships that comprises the universe..." (Three Roads to Quantum Gravity, Lee Smolin)
 
We cannot see the entire universe. We can only see it from our local area where we are and that region which extends around us is approximately 14 billion light years - and pursuant to Einstein's Theory of Relativity, we know also that nothing can move faster than the speed of light.
 
"At this very moment, our galaxy is hurtling toward the Virgo cluster of galaxies at a couple of hundred kilometers a second, faster literally than a speeding bullet. Virgo is pulling us into its gravitational field. At the same time, our galaxy continues to rotate sedately: The invisible hand of gravity ties together the 100 billion stars that make up the galaxy..." (Einstein's Universe, Gravity At Work and Play, by A. Zee - Oxford U Press - 2001)
 
Space and time are integrated into space-time, based on Einstein's theory of general relativity; Space and time are geometrically integrated into a space-time fabric warped, distorted and curved by matter and energy.
 
I don't know if we shall ever fully understand the universe. The world we live in is just the dimension of it we see or have some sense of, but how real is it? We are worlds within worlds. 90% of the cells in our bodies are not our own and at the micro, the smallest scale - the Plank scale of Quantum Physics there are no absolutes; only probabilities. And at the macro scale of galaxies and star systems, the size is so huge we can't ever get to most of what we can imagine is there.
 
  "Earth is no more a rock with some life on it than you are a skeleton infested with cells." -- Dorian Sagan
 
But what I imagine is there are worlds within worlds. Multiverses and many more dimensions than we can now suppose there are - and yet to be discovered, if we ever do. The hint of this is what we already know about ourselves. We are not significant in the way we once thought ourselves to be. Gods and religion may be the glue that holds many of us together but it hardly explains what is out there.
 
What is out there is a microcosmic world or worlds and we are currently exploring the small worlds which exist down to the level of loops and strings and branes.
 
"By now you should be convinced that our universe may have additional curled-up spatial dimensions,; certainly so long as they are small enough nothing rules them out. But extra dimensions may strike you as an artifice. Our inability to probe distances smaller than a billionth of a billionth of a meter permits not only extra tiny dimensions but all manner of whimsical possibilities as well---even a microscopic civilization populated by even tinier green people." (Brian Greene, The Elegant Universe - 1999)
 
Well what if there are also larger dimensions of all manner which we can only imagine might be populated by very BIG green people - or some other organisms? What if their natural motion is very close to the speed of light? In which case our lives, to them, if they were even aware of them, would take place in instants - maybe too quick to even be imagined. Sort of like electrons popping into existence in dark matter and being instantly annihilated by positron-s and the doing it all over again. They exist but in a space-time that we are only now learning to measure and consider. What if we are a tiny conglomeration of organisms which live in worlds within worlds within worlds?
