What happened to the dinosaurs? The prevailing theory for the extinction of dinosaurs involves an asteroid collision at Chicxulub in the Yucatan Peninsula of Mexico. Whether you accept that theory or not, there is no question that there are vast numbers of asteroids in space. They are apparently leftovers from the formation of the planets. At least nine times an asteroid has hit the earth leaving a crater that can be studied and mapped today. Some of the craters are huge. The largest is a crater 186 miles (300 km) wide in South Africa called the Vredefort crater. The question is, “Why would God allow such objects to exist knowing they could become a threat to life on Earth?”
First, we need to realize that such collisions are incredibly rare and so far they have never impacted humans. There are more than half-a-million known asteroids. The largest is Vesta (pictured) which is 329 miles (530 kilometers) in diameter. The smallest are only 33 feet (10 meters) in diameter. Objects smaller than that are called meteoroids. According to NASA, the total mass of every known asteroid is less than the mass of our Moon.
Scientists are studying their chemical composition of asteroids. What they have found is that they are very rich in rare-earth metals as well as iron, nickel, and cobalt. In the future, we may replace depleted resources on Earth by mining asteroids. Experts have estimated that the value of minerals in asteroids is in the trillions of dollars. Two American companies are gearing up to pioneer asteroid mining operations–Deep Space Industries and Planetary Resources.
A recently discovered asteroid is raising new questions. The cosmos is one of the great evidences for the existence of God. Romans 1:18-20 tells us that “we can know there is a God through the things He has made.” Psalms 19:1 tells us, “The heavens declare the glory of God; and the firmament shows His handiwork…” We see a constant stream of new proposals year after year giving possible scenarios about how the solar system and Earth were produced. In the nearly 50 years that we have been writing, we have seen a dozen or so theories advanced and discarded because they couldn’t account for new observations.
This month Science News (May 13, 2017, page 5), carried a story about a strange asteroid. This will once again cause some rearranging of the current best guesses as to how the solar system and the Earth were formed. Research reported in Nature magazine (March 30, 2017) shows an asteroid that revolves around the Sun backwards, even though it is in Jupiter’s orbit. If you were to look at the solar system from the north star, you would notice that everything revolves around the Sun in a counterclockwise direction. Moons, asteroids, and planets are basically all in one plane and all moving the same way. Jupiter is the most massive planet in the solar system, and it has a multitude of rocks called asteroids that orbit around the Sun in the same direction. Now we have an asteroid that is in Jupiter’s orbit but revolves clockwise around the Sun.
If you think about that for a minute, you will see that it would logically follow that in the first orbit this asteroid would have slammed into Jupiter like a car driving the wrong way down a one-way street. In time at least, Jupiter should have sucked in this wayward hunk of rock. The orbit of asteroid 1015 BZ-509 is such that in one orbit it goes on one side of Jupiter and on the next orbit it goes on the other side of Jupiter, so the gravitational jerk of Jupiter is canceled out. Computer simulations show that this arrangement is permanent. It has been going on for a long time and will continue into the future.
News items in the media in early March have made the spectacular announcement that “life material” has been found on Ceres, an asteroid in the asteroid belt between Mars and Jupiter. Technically that announcement is correct, with the weasel word being “life material.” NASA was very careful to announce that they have “not actually found any signs of life on the dwarf planet.” What they have found on Ceres is a spectrograph of light reflected from the surface giving the same pattern as seen in hydrocarbons on Earth–specifically kerite and asphaltite.
We have pointed out repeatedly that finding life in space is not a biblical issue. The Bible doesn’t tell us that God did not create life elsewhere, and He very well may have. There is a deeper motive for announcements like this one. If you are going to teach that life began in a primeval soup full of organic molecules, you have to find the molecules to put into the soup. Amino acids have been found in meteorites and in dark nebulae, but most have been small and very limited in complexity.
