According to the scientists a “force” sends comets hurtling towards Earth every 35 million years.



They explain: As our solar system orbits the centre of Milky Way (our galaxy) in 70m year cycle, is moving through a dark matter disk every 35 million years.
This increase in pattern of comet impacts on Earth.
They came to the conclusion that this could have led to the extinction of the dinosaurs 65 million years ago.

Dark matter is one of the greatest mysteries in physics and astronomy.

More is unknown than is known. We know how much dark energy there is because we know how it affects the Universe’s expansion. Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the Universe is dark energy. Dark matter makes up about 27%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the Universe. Come to think of it, maybe it shouldn’t be called “normal” matter at all, since it is such a small fraction of the Universe.
