An eye opener -list of intriguing scientific facts

A one millimeter sized black hole on earth would have 10% of its its mass and produce energy rays which would equal 10,000 nuclear bombs the size of the 'Tsar' bomb', detonated by the Soviet Union in the late fifties.

Chandrachekhar's limit: the minimum of 1.4 solar mass requirement that a star will turn supernova and consequent black hole.

Wiki wrote:The Tsar Bomba was flown to its test site by a specially modified Tu-95V release plane, flown by Major Andrei Durnovtsev. The Tu-95 bombers were designed to carry much lighter and smaller weapons, meaning the Tsar Bomba was too big to be placed on a missile, and too heavy for the planes to transport it to the target with enough fuel.[18]

Taking off from an airfield in the Kola Peninsula, the release plane was accompanied by a Tu-16 observer plane that took air samples and filmed the test. Both aircraft were painted with a special reflective white paint to minimize heat damage. Despite this effort, Durnovtsev and his crew were given only a 50% chance of surviving the test.[10]

The bomb, weighing 27 metric tons, was so large (8 metres (26 ft) long by 2.1 m (6 ft 11 in) in diameter) that the Tu-95V had to have its bomb bay doors and fuselage fuel tanks removed.[1] The bomb was attached to an 800-kilogram parachute, which gave the release and observer planes time to fly about 45 kilometres (28 mi) away from ground zero, giving them a 50 percent chance of survival.[18] When detonation occurred, the Tu-95V dropped one kilometer in the air because of the shock wave but was able to recover and land safely.[10]


The Tsar Bomba's fireball, about 8 km (5.0 mi) in diameter, was prevented from touching the ground by the shock wave, but nearly reached the 10.5-kilometre (6.5 mi) altitude of the deploying Tu-95 bomber.
The Tsar Bomba detonated at 11:32 Moscow Time on 30 October 1961, over the Mityushikha Bay nuclear testing range (Sukhoy Nos Zone C), north of the Arctic Circle over the Novaya Zemlya archipelago in the Arctic Ocean. The bomb was dropped from an altitude of 10.5 km (6.5 mi); it was designed to detonate at a height of 4 km (13,000 ft) over the land surface (4.2 km (14,000 ft) over sea level) by barometric sensors.[7][17][20]

The original, November 1961, AEC estimate of the yield was 55–60 megatons, but since 1992, all Russian sources have stated its yield as 51 megatons. First secretary Khrushchev warned in a filmed speech to the Supreme Soviet of the existence of a 100 megaton bomb. (Technically the design was capable of this yield.) Although simplistic fireball calculations predicted the fireball would hit the ground, the bomb's own shock wave reflected back and prevented this.[21] The fireball reached nearly as high as the altitude of the release plane and was visible at almost 1,000 km (620 mi) away from where it ascended. The mushroom cloud was about 64 km (40 mi) high (over seven times the height of Mount Everest), which meant that the cloud was above the stratosphere and well inside the mesosphere when it peaked. The cap of the mushroom cloud had a peak width of 95 km (59 mi) and its base was 40 km (25 mi) wide.[22][23]

All buildings in the village of Severny (both wooden and brick), located 55 km (34 mi) from ground zero within the Sukhoy Nos test range, were destroyed. In districts hundreds of kilometers from ground zero wooden houses were destroyed, stone ones lost their roofs, windows, doors, and radio communications were interrupted for almost one hour. One participant in the test saw a bright flash through dark goggles and felt the effects of a thermal pulse even at a distance of 270 kilometres (170 mi). The heat from the explosion could have caused third-degree burns 100 km (62 mi) away from ground zero. A shock wave was observed in the air at Dikson settlement 700 km (430 mi) away; windowpanes were partially broken to distances of 900 kilometres (560 mi).[24] Atmospheric focusing caused blast damage at even greater distances, breaking windows in Norway and Finland. Despite being detonated 4.2 km above ground, its seismic body wave magnitude was estimated at 5–5.25.[10][21] Sensors continued to identify the shockwaves after their third trip around the world.

How long would it take to travel to the Andromeda Galaxy , our nearest galactic neighbor?

2.54 million light years, that is traveling near the velocity of light. But for an other thing: even the very scarce matter in space would in the time wrap matter around the space craft to form an accumulation the size of a large planet.

The Andromeda is in collision course with our galaxy in 4 billion years any way so realistically we only have to wait to meet it.

Relative travel from a different reference point will drastically shorten the time traveled. At near light velocity, the travel time will drastically differ, if the materials used in the spaceahip's construction could be changed.

If the space ship could travel At the speed of light , then, it would take 0 time to get there, but then the journey would become a metaphor for time travel. Perhaps this is what is meant biblically when the allusion- to be with the light is made.

1 light year = 9,460,730,472,580.8 km.
2.54 million light years = 24,030,025,540,000,000,000 km (9,460,730,472,580.8 km x 2,540,000).

Light speed = 299,792,458 m/s = 9,460,730,472,580.8 km/year.

In other words: You need 2,54 million times more than the light needs in one year.
In other words: You need 2,54 million years if you travel as fast as the light does.

Our current technoloy allows us at most about 0.1% of the light speed. :lol:

So, if you will use our current technology and start tomorrow ( :greetings-waveyellow: ), then you will arrive at Andromeda 2.54 billion years later. And when you will come back from your trip after 5 billion years from now, then you will have missed 10 geological "Pangaea" cycles on our planet Earth, if it will not already be outside of the habitable zone of our solar system.

So, realistically said: Forget your trip!

But if you necessarily want to travel, then okay: Have a good trip! :P

I will try to wait for you.

A collision of two galaxies:



What do you think about that collision?

If this collision will come true, then you will need less time for your trip than mentioned in my post above, but your trip will still take too much time. Believe me. My advice is that you should first travel to the Moon, then to the planet Mars and be happy there. :P

Good luck!

In the middle of the Saggitarius Galaxy, there is a Super massive black hole with mass of 4 million suns. It is 25 thousand light years away. There will be a composite photograph of it available , taken with multiple radio telescopes in a few weeks from now. This cosmological colossus was formed at the inception of the milky way. .

An interesting fact: The messiah sta by r which the three kings from the middle East we're led to Bethlehem, came to be seen as red, by no lesser figure then Seneca. According to modern astronomy, Sirius , the dog star was really white , so the conclusion reached is that a dark star next to it of a brilliant red, cast the red light on it. Most Romans were not aware of this and did not see the dark star.. The effect lasted from the time of Jesus to one hundred A.D..

Considerable study supported this, wherein the Measianic Star was anticipated way before Jesus's birth, from the Middle East.

The analysis by various scholars is complex and detailed , but I can furnish the references.
