I was watching a science program explain how once we discovered the Universe was expanding, it was a "simple" matter to imagine it rewound; and, to reach the "obvious" conclusion that it must have started from a single point. It went on to explain that the universe expanded to the size of an orange in one trillionth of one trillionth of a second. After 100 seconds the universe had expanded to several thousand light years. Oh, really?
How did the universe expand to several thousand light years in 100 seconds if the speed of light is the velocity limit for anything and everything? And if you call this a "singularity" isn't that just a cop out word and a confession that we don't really know what is going on?
Or, is popular science programs on television just misinformed? Many of them feature prominent physics such as Dr. Michio Kaku or Steven Hawlings.
So, did (and/or) does the universe continue to expand at a velocity greater than that of the speed of light? I think physics is a total zoo right now- and apparently some of the theories have escaped and are running wild on television shows.
But, if the universe is expanding faster than the speed of light and the expansion is accelerating, then it would appear that if we pointed our telescopes out to the visible edge, we might be able to detect a galaxy whose speed away from us is at a threshold. At some point it should "blink out", as it accelerates and overcomes the speed of light. Is that an observation that is technically possible?
