Briefly, the theory is that the mass extinction which included the loss of the dinosaurs at the end of the Cretaceous period was caused by the impact of a large asteroid.
Theory suggests that it is a remnant of a large asteroid that struck the Earth
The asteroid collision theory, which was brought to wide attention in 1980 by Walter Alvarez and colleagues, links the extinction event at the end of the Cretaceous period to a bolide impact approximately 65.5 million years ago.
A lack of evidence would weaken any theory. But the well known asteroids have well defined orbits.
The theory that the moon was formed when a large asteroid collided with the Earth, causing debris to coalesce into the moon, would be most supported. This is known as the Giant Impact Hypothesis, which suggests that the moon's irregular shape would be a result of its violent formation process.
No, the Big Bang was not an asteroid. The Big Bang theory is the scientific explanation for the origin of the universe, proposing that it began as a singularity and has been expanding ever since. An asteroid is a rocky object in space that orbits the Sun, and is not related to the concept of the Big Bang.
Walter and Luis Alvarez proposed the theory that a large rocky object, such as an asteroid or comet, colliding with Earth caused the mass extinction of the dinosaurs. This theory is known as the Alvarez Hypothesis.
After finding Iridium, now he got enough evidence for his theory. That Iridium was from the asteroid that impacted the Earth and caused dinosaurs to perish.
The theory of the asteroid belt is - it was another planet that failed to 'gel' properly at the time the solar system was being created.
an asteroid hit
The second theory says that the moon is a captured asteroid.
The theory of an asteroid named Orpheus will hit Earth and destroy civilization in the future years. The asteroid is predicted to hit Mexico. Don't be afraid because it may or may not happen :)
In 1980, Luis and Walter Alvarez, a father and son team of geologists, decided to study the boundary between the Mesozoic and the Cenozoic. They soon found many signs of an asteroid impact, including iridium and impact spherules.

I does not. The asteroid would of had to knock out the entire earth for that to happen. If you think of the facts it is just not possible.
It is a rock called an asteroid, or comet, or a volcanic eruption.

She watches to many stupid crazy theory videos on the internet... :P
