The Martian "Worms"
There are some people who claim that the mysterious EDM formations in these photos are giant worms, digging through the soil. Now most of you can probably tell that the idea is rather preposterous, and you wouldn't be wrong.
We can say with absolute certainty that they are not worms, because of their immense size.
The largest officially recognized land animal on Earth right now is the African Bush Elephant. This creature is massive, 6000 to 9000 kilograms. On Earth, its weight is about 13,000 to 20,000 lbs. This is already a heavy animal, approaching the limit for a land dwelling creature in Earth's present gravity. Scaling of muscle tissue and bone strength provides strong evidence for this.
The largest known land animal on Earth ever was Amphicoelias, a sauropod dinosaur approaching 200 feet long. Now mainstream weight estimates place it over 100 tons, but that weight estimate is based off of a discredited assumption about gravity as well as the ignorance of how much weight muscles and bones can support. In reality, Amphicoelias probably wasn't much heavier than an elephant due to the lesser force of gravity, which is estimated by some to be around a third or a fourth of what it is today. But if that's large for a creature on Earth, that's still nothing compared to the mysterious form you see on Mars.
Another problem with the worm theory is that the creature would simply be too big to dig through dirt, especially at that depth. One of the best ways to move, as a worm, is to propel yourself forward through compression and expansion, like an accordion, with a sharp tip on the front end, pushing dirt to the sides. This is fine for small worms, but when you get big, you evolve to be longer, as you are at a disadvantage if you're large and wide.
The greater your width, the deeper you would need to go. The increasing weight of the dirt on top of you, coupled with the great amount of pressure and the more tightly packed dirt, makes this a disadvantageous trait.
Also, there is no explanation given as to what the worms are supposed to be living off of. This is a serious problem.
