THE AGE OF THE UNIVERSE (Negativity vs Vitality) (Michio Kaku, 2004)

意思是說,無何以生有,需要黑暗能量,需要黑暗材料,光就是生,生就是光,但是你要理解,黑暗才是常態,光只是詐(乍)現,

Confirming previous experiments, the WMAP satellite showed that the visible matter we see around us (including the mountains, planets, stars, and galaxies) makes up a paltry 4 percent of the total matter and energy content of the universe. (Of that 4 percent, most of it is in the form of hydrogen and helium, and probably only 0.03 percent takes the form of the heavy elements.) Most of the universe is actually made of mysterious, invisible material of totally unknown origin. The familiar elements that make up our world constitute only 0.03 percent of the universe. In some sense, science is being thrown back centuries into the past, before the rise of the atomic hypothesis, as physicists grapple with the fact that the universe is dominated by entirely new, unknown forms of matter and energy.

According to the WMAP, 23 percent of the universe is made of a strange, undetermined substance called dark matter, which has weight, surrounds the galaxies in a gigantic halo, but is totally invisible. Dark matter is so pervasive and abundant that, in our own Milky Way galaxy, it outweighs all the stars by a factor of i0. Although invisible, this strange dark matter can be observed indirectly by scientists because it bends starlight, just like glass, and hence can be located by the amount of optical distortion it creates.

Referring to the strange results obtained from the WMAP satellite, Princeton astronomer John Bahcall said, "We live in an implausible, crazy universe, but one whose defining characteristics we now know."

But perhaps the greatest surprise from the WMAP data, data that sent the scientific community reeling, was that 73 percent of the universe, by far the largest amount, is made of a totally unknown form of energy called dark energy, or the invisible energy hidden in the vacuum of space. Introduced by Einstein himself in i9i7 and then later discarded (he called it his "greatest blunder"), dark energy, or the energy of nothing or empty space, is now re-emerging as the driving force in the entire universe. This dark energy is now believed to create a new antigravity field which is driving the galaxies apart. The ultimate fate of the universe itself will be determined by dark energy.

No one at the present time has any understanding of where this "energy of nothing" comes from. "Frankly, we just don't understand it. We know what its effects are [but] we're completely clueless . . . everybody's clueless about it," admits Craig Hogan, an astronomer at the University of Washington at Seattle.
