Neil deGrasse Tyson Disproves Creationism on Cosmos (Mediaite)
Astrophysicist Neil deGrasse Tyson continues to challenge long-held religious beliefs on his weekly prime time science show on Fox, Cosmos: A Spacetime Odyssey. At the beginning of Sunday’s episode, Tyson offered up a compellingly straight-forward reason why the Earth cannot possibly be 6,500 years old, as creationists believe it to be.
As Tyson explained to his viewers, we measure Earth’s distance from other planets and galaxies in the universe by the speed of light. On average, Neptune is four light-hours away from Earth, meaning the Neptune we see when we look through a telescope is as it appears four hours ago.
For another example, Tyson looked at the Crag Nebula, a supernova remnant that just happens to be 6,500 light-years away from Earth. This means that when we view the Crab Nebula through the telescope, we are seeing it 6,500 years in the past. Because there are objects beyond that point, we can see with our own telescope-enabled eyes that the universe is older than 6,500 years.
