Now you just can’t get up and say, “Hey, you know what? There is a repulsive force out there that is driving the different parts of the Universe apart, forcing it expand rapidly, instead of allowing gravity to shrink it, which is what one would normally expect.” This is too serious a matter to do hand-waving as they say. I wish to assure you that serious science is not done this way, and in fact, much work has been done to give a reasonable theoretical foundation for the concept of a repulsive energy that would take care of the observed expansion of the Universe, and the value of Ω it suggests. But I am afraid I cannot go into those technical details. Let us take comfort, that thanks to COBE results we not only know that Ω is close to unity, but also that there is a way to understand the expansion of the Universe that this value of Ω suggests, an expansion that has actually been observed.
There is another curious thing about this dark energy business. Remember the famous Cosmological parameter Λ that Einstein introduced and then abandoned, declaring it to be the greatest blunder of his life? [See SFI – 02.] It turns out that this dark energy is closely related to that Λ! Einstein would sure have loved that, had he been alive! Sometimes, history turns around in a strange manner!
The Universe created by God is full of mysteries! More about them next time, when you would encounter some really amazing concepts. Meanwhile, I wish to leave you with small question, which is: “Name a well known rock star who recently completed his Ph. D thesis in astrophysics and submitted it for examination after more than three decades of absence, working in the music world!” We will publish the names of all who have submitted correct entries! You know where to write to us, isn't it.
