Can Mini Black Holes actually exist? - Page 2

And here is the answer to the OP...

NO, mini/micro black hole do not and cannot exist.

Black Holes are ALL about gravitational collapse....period!
It takes a star at least 3 to 8 times the mass of our sun to create a stellar black hole, so there are also no black holes inside the earth or any other massive bodies!

Speed or Accleration of baryonic Matter do NOT create black holes!

Collisions of baryonic Matter do NOT create black holes!

I asked the questions in that order for my own reasons mainly due to the eye witness accounts. Snippets from wiki here.

part of Testimony of S. Semenov "the sky split in two and fire appeared high and wide over the forest".

then this part of Testimony of Chuchan of Shanyagir tribe "it became mighty bright, how can I say this, as if there was a second sun" and "I looked there and saw another flash, and it made another thunder. But the noise was less than before. This was the fourth strike".

and this part of from the Sibir newspaper "some strangely bright (impossible to look at) bluish-white heavenly body, which for 10 minutes moved downwards. The body appeared as a "pipe", i.e. a cylinder".

A pity string theory could account for it but until it is science it can't be commented on.

I have taken just the snips that I find most accurate to views that I am not permitted to comment on here, none the less I feel this sort of eye witness account is vitally important to determining what happened.

Again I will not argue here or promote any particular theory here but these are related observations of what happened at Tunguska. I believe they are exceptional.

There are still an intriguing number of hypothesis for this event, including this:-
"In 1965, Cowan, Atluri, and Libby suggested that the Tunguska event was caused by the annihilation of a chunk of antimatter falling from space".

Even micro black holes were discussed:-

Quote:

"Hawking did indeed calculate [17] that a primordial black hole would "radiate away all its mass," but his calculation showed that it would do so only once said mass dropped below 1014 g (= 100 million metric tons)"

Given that size event horizon would the microscopic glass sphericals found in the lunar samples and also at Tunguska be "right size"?

Expeditions were sent much later here :-

Quote:

Expeditions sent to the area in the 1950s and 1960s found microscopic glass spheres in siftings of the soil. Chemical analysis showed that the spheres contained high proportions of nickel and iridium, which are found in high concentrations in meteorites, hinting that they were of extraterrestrial origin

From the article:-

Quote:

During the 1990s, Italian researchers extracted resin from the core of the trees in the area of impact, to examine trapped particles that were present during the 1908 event. They found high levels of material commonly found in rocky asteroids and rarely found in comets

Microscopic glass sphericals are used to indicate an impact from extra terrestrial origin. This based on the blast of 10 to 20 mega tonnes:-

Quote:

In 1973, Albert A. Jackson IV and Michael P. Ryan, Jr., physicists at the University of Texas, proposed that the Tunguska event was caused by a "small" (around 1020 g to 1022 g) black hole passing through the Earth[16]. Unfortunately for this hypothesis, there is no evidence for a so-called "exit event"

If it had been just a glancing pass through the atmosphere there need not be either an entry or exit hole just a series of "burps".

When using 'microscopic glass sphericals' to determine if an asteroid is involved in an impact

1. Are the glass sphericals for each impact of uniform size?
2. Would they survive being burnt in a normal fire place?
3. If so would it be worth sifting ash from the area to check for timber imbedded glass sphericals?
4. Are there known examples of glass sphericals imbedded in the timber?
5. Are the glass sphericals in the moon samples consistent in size and in fact similar in size to those found on the earth?

It all revolves around this :-

Quote:

At around 7:15 a.m., Tungus natives and Russian settlers in the hills northwest of Lake Baikal observed a column of bluish light, nearly as bright as the Sun, moving across the sky. About 10 minutes later, there was a flash and a loud "knocking" sound similar to artillery fire that went in short bursts spaced increasingly wider apart.

A meteorite or asteroid would not have the brightness of the sun. A blue column of light or tube is not that different from what is seen in the dark matter density map, tubes vortex and ripple structures.

If as one super string theory suggests light could be distorted by one of these gravity lensing the light from galaxies behind it.

How would we know that we were not actually in one ourselves?

Is there any similarity in size of micro glass sphericals and have they been found in the soil samples analysed by the Martian rovers?

I am expecting to find lunar glass sphericals as smallest, Martian if any as slightly larger then the Tunguska samples as the larger ones.

Second question if micro glass sphericals are an indication of extra terrestrial debris is there a very similar pattern to chemical composition and size?
