Neil deGrasse Tyson: Russian meteorite was 'once a decade' event

http://todaynews.today.com/_news/2013/02/15/16973245-neil-degrasse-tyson-russian-meteorite-was-once-a-decade-event?lite

A large fireball rocketed across the skies over Russia's Chelyabinsk region early Friday, reportedly injuring about 400 people. But according to astrophysicist Neil deGrasse Tyson, the impact could have been much worse had it entered Earth's atmosphere above a more populated region.
"It's a shock wave ... this asteroid is coming in, it hits Earth's atmosphere, and it feels like a brick wall to it, because of how fast it's moving. When you hit a brick wall, you basically explode."
Likening the meteorite collision with our atmosphere to the impact of a bomb blast, Tyson explained that a shock wave of this magnitude "shatters glass, or anything fragile or breakable over a huge radius."


Comments from a real astrophysicist, posted to counter some of the reporting from CT sites.

"Mexican archaeologists announced this week that a figure of the god, called Huehueteotl, was found in a covered pit at the apex of the Pyramid of the Sun at Teotihuacan, a popular archaeological site north of Mexico City.

"... the discovery suggests that a long-disappeared temple at the top of the pyramid was used to perform ritual offerings to the fire god...

10. Because billions of years ago, gravitational forces caused matter to condense...

into a giant ball, where the pressure is so intense and the matter so dense, that thermonuclear fuion takes place, and hydrogen is fused into helium, releasing enormous quantities if energy.

Thinking that the incoherent mystic ramblings of superstitious, savage ancient civilizations are somehow relevant to the world today is nonsense. Ancient civilizations are important or their historical value only. They show us from where we came, and how far we've journeyed and how much we've learned since then.

23. At least not as far as any independent historical corroboration, no.

Although it seems like an odd thing to just make up.

More recently, there is no historical corroboration of the existence of "Jesus", either; I think a stronger case can be made that "he" is a wholly fictional invention.

The one fat one balances out the two skinny ones (sorry, couldn't resist)

Seriously, some scholars think the Jesus we understand is an amalgam of three other "Jesuses"

29. The research I've read speculates that a few things may have happened, primarily a mystery cult

like that of Mithras, etc. which had an entirely mythical "Jesus" figure who had no objective historical reality, and then around 100-200 CE it got transmogrified retroactively into a historical existence. If you look at the records from the "time of" Jesus, there is no indication, outside the Bible, that such a figure was running around. There were, as you allude, many sorts of leaders, figures, charismatic preachers or rabbis, etc. and some of what became the historical "Jesus" may have been based on some of those guys, too.

Yeshua Ben Yusuf (Joshua, son of Joseph) was his real name.

Jesus is a bastardization of Joshua, which was a VERY common name back then

28. and people like to embelish...

We know all the mythical stories of the bible were stolen from other mythology...

But the "Whole World Flooding" was probably just an ancient redneck tale told through generations


http://en.wikipedia.org/wiki/Black_Sea_deluge_hypothesis

In 1997, William Ryan and Walter Pitman published evidence that a massive flooding of the Black Sea occurred about 5600 BC through the Bosporus, following this scenario. Before that date, glacial meltwater had turned the Black and Caspian Seas into vast freshwater lakes draining into the Aegean Sea. As glaciers retreated, some of the rivers emptying into the Black Sea declined in volume and changed course to drain into the North Sea. The levels of the lakes dropped through evaporation, while changes in worldwide hydrology caused sea level to rise. The rising Mediterranean finally spilled over a rocky sill at the Bosporus. The event flooded 155,000 km2 (60,000 sq mi) of land and significantly expanded the Black Sea shoreline to the north and west. According to the researchers, "40 km3 (10 cu mi) of water poured through each day, two hundred times what flows over Niagara Falls... The Bosporus flume roared and surged at full spate for at least three hundred days."

Samplings of sediments in the Black Sea by a series of expeditions carried out between 1998 to 2005 in the frame of a European Project ASSEMBLAGE and coordinated by a French oceanographer, Gilles Lericolais, brought some new inputs to the Ryan and Pitman's hypothesis. These results were also completed by the Noah project led by the Bulgarian Institute of Oceanography (IO-BAS). Furthermore, calculations made by Mark Siddall predicted an underwater canyon that was actually found.

36. Living in the Pacific NW, I can tell you for sure there have been some big floods in recent history

http://hugefloods.com/ColumbiaGorge.html


Still, I doubt it's a case of "one big flood" living on through memory. Probably more like these were disparate events that were so traumatic they left behind these oral histories which end up looking similar. I mean, one giant flood is pretty much like any other giant flood.

I have no memory of the other couple that should statistically have occurred over or near land in my lifetime.

Not saying they don't occur, just surprising that I've never registered such regularity in these things.

47. No, the point is that something this size happens somwhere on Earth about once a decade

Not that it happens in a populated area once a decade. So about 70% of the time it will be out at sea, and quite likely no-one will see it at all, and it also could happen over less-populated areas of land.
