Re: Let the truth be known
Do you believe in the Big Bang Theory? This is the "bible" to many. For many years it made as much sense as anything to me. But I always wondered what happened before the Big Bang? No one could answer that and it left a lot of doubt in my mind.
A different theory has emerged.
Physicists Debate Hawking’s Idea That the Universe Had No Beginning
In 1981, many of the world’s leading cosmologists gathered at the Pontifical Academy of Sciences, a vestige of the coupled lineages of science and theology located in an elegant villa in the gardens of the Vatican. Stephen Hawking chose the august setting to present what he would later regard as his most important idea: a proposal about how the universe could have arisen from nothing.
The Big Bang theory had other problems. Physicists understood that an expanding bundle of energy would grow into a crumpled mess rather than the huge, smooth cosmos that modern astronomers observe. In 1980, the year before Hawking’s talk, the cosmologist Alan Guth realized that the Big Bang’s problems could be fixed with an add-on: an initial, exponential growth spurt known as cosmic inflation, which would have rendered the universe huge, smooth and flat before gravity had a chance to wreck it. Inflation quickly became the leading theory of our cosmic origins. Yet the issue of initial conditions remained: What was the source of the minuscule patch that allegedly ballooned into our cosmos, and of the potential energy that inflated it?
Hawking, in his brilliance, saw a way to end the interminable groping backward in time: He proposed that there’s no end, or beginning, at all. According to the record of the Vatican conference, the Cambridge physicist, then 39 and still able to speak with his own voice, told the crowd, “There ought to be something very special about the boundary conditions of the universe, and what can be more special than the condition that there is no boundary?”
The “no-boundary proposal,” which Hawking and his frequent collaborator, James Hartle, fully formulated in a 1983 paper, envisions the cosmos having the shape of a shuttlecock. Just as a shuttlecock has a diameter of zero at its bottommost point and gradually widens on the way up, the universe, according to the no-boundary proposal, smoothly expanded from a point of zero size. Hartle and Hawking derived a formula describing the whole shuttlecock — the so-called “wave function of the universe” that encompasses the entire past, present and future at once — making moot all contemplation of seeds of creation, a creator, or any transition from a time before.
“Asking what came before the Big Bang is meaningless, according to the no-boundary proposal, because there is no notion of time available to refer to,” Hawking said in another lecture at the Pontifical Academy in 2016, a year and a half before his death. “It would be like asking what lies south of the South Pole.”

Sorry but your "All Search Engines filter results." doesn't hold water. I used to use Google but when things I used to be able to find there could no longer be found on Google but could be found on other search engines I quit using them.Comment

Re: Let the truth be known
There s a program on Science Channel called How the Universe Works. One of the theories I saw there dealt with the questions of what was before the big bang and what happens to the matter and energy that get pulled into a black hole. The theory was that at some point in the past, future, that a black hole became, becomes, so massive that it pulls in the rest of the universe at which point it explodes into a new big bang.Comment

Criminals will always seek any excuse or reason to profit by convincing poorly educated and uninformed South American citizens to attempt to cross the border.
President-elect Joe Biden’s choice of Alejandro Mayorkas to lead the Department of Homeland Security thrilled immigrant advocates on Monday and won praise from former DHS leaders who described him as a savvy department veteran who would try to stabilize the organization after years of front-office turmoil under President Trump.
The son of Cuban Jews who fled Fidel Castro’s 1959 Revolution, Mayorkas would be the first immigrant and first Hispanic American to lead DHS. Mayorkas’s first public statement after the announcement was an indication that immigration, for him, is deeply personal.
Current and former DHS officials who have worked with Mayorkas praised him as someone familiar with the department and capable of handling the challenge of low employee morale at several of its key agencies. DHS went through a period of unprecedented turmoil under Trump, with five different leaders, only two of whom were Senate-confirmed. Many of DHS’s top posts were left vacant or filled with leaders in acting roles during the past four years.
