Another Gun Issue to Consider

another gun issueThere is another gun issue which we rarely talk about. It relates in some ways to meteorites.

Many years ago, a lady in Alabama was sitting on her couch with her leg up on the coffee table. Suddenly a large chunk of rock came crashing through the ceiling striking her on the leg and continuing through the floor. It turned out to be a meteorite, a piece of rock from outer space. The rock survived its journey through Earth’s atmosphere and reached the surface to land in the woman’s home. We have had sporadic meteors striking our atmosphere at 79,000 to 130,000 miles-per-hour. Atmospheric drag slows these hunks of rock to 200 to 400 miles-per-hour. Our atmosphere is designed so that larger meteoroids break up about 10 miles above the surface, and the fragments produced rarely get to the ground.

So there is another gun issue in which humans in celebration fire a gun straight up into the atmosphere. That action poses great danger. In Puerto Rico alone, two people were killed and 25 injured on New Year’s Eve because of celebratory bullets that come down on their heads. A bullet has to achieve a velocity of 157 miles-per-hour to penetrate human skin and damage organs. Bullets fired into the air can reach a speed of 400 miles per hour upon their return to the ground.

In Los Angeles between 1985 and 1992 doctors at Martin Luther King Jr./Drew Medical Center treated 118 people for random falling bullet injuries, and 38 of them died. A 1994 study published in the Journal of Trauma showed that of those 118 people, 77% were hit in the head and had a mortality rate of 32%. Rifle bullets of .30-caliber fired straight-up reach altitudes of 10,000 feet and descend at 300-600 feet-per-second. Even bullets from handguns fired straight-up return to the ground at speeds between 150 and 250 feet-per-second.

So we have another gun issue. Almost always, your safety is more endangered by what humans do than the dangers of the planet God created for our home. I am reminded of the very old line from the Pogo comic strip: “We have met the enemy, and it is us.”

Asteroids Have Value

Vesta, Largest of Asteroids

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.

We think too small when we think that God planned for humans to be limited by the resources of Earth. What appeared to be a threat in the past may turn out to be an incredible blessing from God in the future.
