The Big Bang (Science Foundations) by Mike Perricone

By Mike Perricone

This identify follows the pioneering obserations of Edwin Hubble and the early insights in cosmological thought by means of Alexander Friedmann and Father Georges Lemaitre. The discoveries of the cosmic microwave heritage and the growth of the universe set the degree for brand new facts approximately substantial bang origins.

Hubble’s first dark matter observation had shown a “ring” resulting from the collision of two massive galaxies about 5 billion light years from Earth. Dark matter’s gravity slightly deflected the light from distant galaxies—light that had traveled through space (continues) 36 The Big Bang (continued) toward the Hubble telescope. The effect is similar to the result of Arthur Eddington’s famous solar eclipse observation in 1919, which confirmed Einstein’s prediction that the gravity of the Sun was strong enough to deflect the path of light from distant stars.

If you double the original size of the balloon 10 times, the result is 1,024 times the original size. ” It looks 54 Cosmic extremes 55 complicated when it is written 210 (two to the tenth power). But the arithmetic is simple (though tedious). The exponent (10) tells you how many times the base (in this case, 2) is written down and multiplied by itself. So, 210 is simply: 2x2x2x2x2x2x2x2x2x2 = 1,024 How fast can you imagine the balloon doubling in size? The fastest pace you can imagine is nowhere near the speed that the Universe expanded with the Big Bang.

The ripples (called quantum fluctuations) would grow in intensity. Much later, the ripples would form the large-scale structure of the Universe—the galaxies and galaxy clusters. Inflation predicts a smoothness, or uniformity, in the Universe varying only by about one part in 100,000. That prediction is almost exactly what NASA’s Cosmic Background Explorer measured in 1990. Measurements from another NASA space probe, the Wilkinson Microwave Anisotropy Probe (WMAP), charted the variations even more precisely in 2003, again backing up predictions from inflation theory.
