The boulder in Saudi Arabia was split in half, which made netizens guess that "aliens" split it with lasers.

Recently, an incredible crack appeared in the middle of a huge sandstone stone in Saudi Arabia, which triggered a hot discussion among netizens. On the popular Reddit forum "It's really interesting", some people suspected that the rock was cut symmetrically, which may have been split in two by "aliens" with a laser beam, but geologists suspected that it was the result of freezing and thawing weathering.

Geologists say that this shape is a typical weathering process at first glance. Water seeps into cracks, freezes and hardens at low temperature, splitting the rock in two. But on the unfamiliar Reddit website, netizens don't think so. "I'm not saying it's an alien, but it's what aliens do." "Didn't aliens split the stone in half with a super laser pen?"

However, geologists refuted this rumor, saying that behind this magical structure, the truth may not be so interesting. Cherie Lewis, a researcher at Bristol University, told the Daily Mail that, in fact, this is more likely the result of freezing and thawing weathering. "Due to the freezing and thawing weathering process, cracks may be formed, which is caused by water entering small cracks in rocks. When the temperature drops, water freezes and expands, which leads to the expansion and extension of cracks. When the ice melts, the water in the cracks will flow deeper and deeper. This process will be repeated for thousands of years, even millions of years, until the rock finally cracks. This process is accompanied by wind erosion. In a desert environment, wind erosion is like sandblasting, which explains why boulders exist independently. "

However, a reasonable explanation cannot convince everyone. Some people commented that this crack is really a bit too perfect, unlike the result of nature. A guy named David Maginess commented, "Obviously, this is a quaternary laser from the Galaxy space shuttle landing craft." In any case, the wonders of nature will really make a shocking spectacle.
