What If We Drop Godzilla From Space?
The Theory we mention in this video may be quite confusing: Let me give you some lines in the description:
When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. But still then, a few large objects do make it through and create gigantic craters and an explosion of tremendous levels.
Meteoroids have a pretty big size range. They include any space debris bigger than a molecule and smaller than about 330 feet (100 meters) space debris bigger than this is considered an asteroid. So we can consider Godzilla in space, again, not space Godzilla, he is a totally different thing, So Godzilla in space as an asteroid as he has surpassed the benchmark in size.
Meteoroids enter the atmosphere at extremely high speeds of 7 to 45 miles per second (11 to 72 kilometers per second).Earth's atmosphere, on the other hand, is full of matter, which creates a great deal of friction on a traveling object.
This friction generates enough heat up to 3,000 degrees Fahrenheit, or 1,649 degrees Celsius to raise the meteoroid's surface to its boiling point, so the meteoroid is vaporized, layer by layer. But still the larger objects do survive the upper atmosphere and due to the intense changes in heat and pressure they end in airbursts which are very powerful explosions comparable to the most powerful nuclear weapons.
Larger objects survive the airburst mode, and come crashing into the earth and create a catastrophe. sometimes wiping out a majority of the terrestrial ecosystems. So, Can Godzilla create such an impact or would he end up in an airburst mode. We can say for certain that due to his size and weight, he will not burn up on re entry.
Let's put two presumptions first, Number 1 - Godzilla will not vaporize layer by layer and become smaller during reentry as we have seen him in his burning form, melting stone and metal that were close by. Number 2 - His velocity would be close or equal to meteors and meteorites entering the earth in the range of 7 to 45 miles per second or 11 to 72 kilometers per second. Lets put it at 17
So based on research on impact events, we have found out that the biggest meteoroid that will burn up during reentry in below 4 meters in diameter, while between 4 and 90 meters or 13 and 300 feet, they usually end up in airburst explosion between 1 kiloton and 28 megatons.
So an impactor with a diameter of 100meters or 330 feet falling at a velocity of 17 kilometers per second and at a 45 degree angle, will cause a gradual release of 45 megatons during reentry burn up and when it crashes, the explosion would be around 3.4 megatons, somewhat in the range of today's thermonuclear warheads. that is due to them losing mass as they burn up layer by layer.
The closest match to Godzilla's size is a 130 meter impactor, let's say it is falling at the same speed and angle. During reentry it will gradually release close to 103 megatons and due to its larger size, a bigger fragment would actually hit the surface with a force of 31.4 Megatons and creating a crater of 2 kms in diameter.
But taking presumption number 1 that is Godzilla will not burn up layer by layer during reentry, this would make the G-man's force way more than just 31.4 megatons and a crater of 2 kilometers. And since more than half of the impactor is burned up, It leaves only half the size of the original measurement,
So, Godzilla's more equivalent impactor size would be a 250 meter diameter Rock that will crash down to earth with only half its size that is 125 meters in diameter touching down. And thankfully we have found out from good sources that such an impactor would release close to 600 megatons during the crash on to earth and creating a crater of nearly 4 kilometers or 2.5 miles wide.
So, there you go, if we dropped Godzilla from space he would crash down with a force of 600 megatons or equivalent to 12 Tsar Bombas. In case there are some of you who don't know what a Tsar Bomba is, It is humanity's largest ever bomb, a hydrogen bomb exploding with a force of 50 megatons. But what would happen to the city of Boston?
