Any hypothesis, Gould says, begins with the collection of facts. In Large amounts of iridium – a chemical element that is not a part of the Earth’s crust composition – were originally found in rocks of Europe and United States, and have been found everywhere ever since. Iridium, common in meteorites, is a testable evidence of the disaster hypothesis. Gould continues that the Cretaceous debacle, which is one of five episodes of mass dying, occurred at the same time as the large comet might have smashed into the Earth. The author believes this is not merely a coincidence, rather, it is a proof of the cause-effect relationship. The demise of a wide range of habitats along with the extinction of dinosaurs gives an inestimable advantage to the disaster theory over other claims, the author adds. The comet struck the Earth, and habitats, from terrestrial to marine, died with geological suddenness. Finally, this hypothesis has had an impact on the study of an atomic war and its consequences. A nuclear war, Gould says, may cause a huge drop in temperatures and result in the extinction of humanity. Testable evidence, study, development, contribution – all this makes good science.
Have you ever considered that the moon may not be exactly what it seems to be? Science says that the moon was a result of the Earth colliding with another planet, causing a rocky mass to break free from the earth and be pulled into orbit by the force of gravity. Conspiracy theorists have considered the possibility that the moon may be something more than just a rocky mass orbiting the earth. A theory that has been created regarding our moon is called The Hollow Moon Theory. This theory tries to prove that the moon may just be a cover or a protective layer around an alien's UFO. It may be hard for some to go against scientific research, but there is a possibility that something other than a collision is responsible for the formation of our moon.
The Moon has been around for 4.5 billion years. “The leading explanation for how the moon formed was that a giant impact knocked off the raw ingredients for the moon off the primitive molten Earth and into orbit” (Choi, 2017) about 95 million years after our solar system was born. This collision is thought to had been between a Mars size like object and earth. Back then Earth was a ball of molten magma. Once the object crashed with earth, the object collected magma and it was sent into orbit by the collision. After 100 million years all that magma in the object was able to crystallize and form the Lunar crust. With time it crystallized more and more giving us our beautiful moon as the only natural satellite of our home Earth.
Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later been captured by their planets. Still others, such as Earth's Moon, may be the result of giant collisions. Collisions between bodies have occurred continually up to the present day and have been central to the evolution of the Solar System. The positions of the planets often shifted due to gravitational interactions. This planetary migration is now thought to have been responsible for much of the Solar System's early
Moon Landing Was the Moon landing real or a hoax? The moon landing was a major scientific breakthrough and a great day for America. The problem is, it might’ve been faked. There are many pieces of evidence showing that it could have been faked but there is also evidence showing
Aim To determine whether the height at which a marble is dropped affect the size of the crater. Scientific knowledge Impact craters are geologic structures formed when a large meteorite, asteroid or comet smashes in to a planet or a satellite. Meteorites are small rocks in space that hit the earth's atmosphere at
When Apollo astronauts carried samples of the moon’s surface back to earth, the rocks and sediments has shown something incredible. It contained clues to how Earth and the Moon formed as well as the history of the Sun. The scientists looked for what life would be like if humans could live on the moon. The Apollo 11 mission brought back the first geologic samples from the Moon back to Earth. Astronauts collected twenty-two kilograms of material which acquired samples of the lunar "soil," fifty rock samples and two core tubes which was found below the moon’s surface. All the samples was not composed with any water which provided no evidence for living organisms in the Moon's history. They figured out that there was volcanic activity since they
There are many different theories about how the moon was formed. People believe different things. I believe one is more reliable than all the others. I think the Big impact theory is the most trustworthy. The Big Impact theory has many different pieces of evidence behind it. The other ones i could barely find any.

Purpose: The purpose is to determine if the angle of impact affects the diameter and depth of a crater. Background Research: A meteoroid is a small chunk of rock that has been broken apart from a much larger chunk of rock called an asteroid, these chunks of rock are located in
In 1975, two scientists by the name of Dr. William K. Hartmann and Dr. Donald R. Davis, came up with a groundbreaking new theory on how the moon was created. Their theory stated “At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing.

3. The most supported theory of moon formation today is that a similar sized planetoid (Theia) to our early proto-earth moved closer and closer until finally slamming into earth – being partially absorbed and then throwing off an immense amount of matter. [see image below] This impact was responsible for both the formation of the moon and the tilting of the earth on its axis.
FORMATION OF THE MOON Many believe that while Early Earth was undergoing accretion, it had a massive collision with a large body- as huge as the size of Mars (see Fig. 2.). This collision produced a shower of debris around the Earth and thrusted it into space (Grotzinger and Jordan, 2010). “According to this theory, the Earth reformed as a boy with an outer molten layer hundreds of kilometres thick- a magma ocean.” (Grotzinger and Jordan, 2010). Marshak (2007) deduced that the Moon was formed from the accretion of the debris floating around the Earth. He also suggested that the Moon’s composition resembles that of the mantle because of the way the Mars-sized body collided with the Earth. From this, we can assume that when the collision happened- it did not disturb the Earth’s iron-nickel core that was already formed. The formation of the Moon must have happened 4.51 billion years ago- between the early stages of the accretion of the Earth which was 4.56 billion years ago,) and “the formation of the oldest Moon rocks brought back by the Apollo astronauts (4.47 billion years ago,)” (Grotzinger and Jordan, 2010).
The moon is by far the biggest and most easily recognizable object in earth’s atmosphere that can be perceived by the naked eye on a cloudless night. It is hypothesized that it came into existence nearly 4.5 billion years ago, from residual debris after a planetary body collided with earth. Although, considered the runner-up to the sun as the second brightest object in the sky, its illumination is deceitful, insomuch as the moon is not a source of light, but instead reflects the sun’s illumination from the half of the moon that is in direct alignment with the sun at that time. More readily identified as a satellite of the earth rather than as a planet itself or even a star, it has a diameter a quarter of the size of earth’s size and it
