On July 20, 1969, sharply at 3:17 pm ET, Apollo 11 lander touched the Lunar surface of the moon. American astronauts Neil Armstrong (1930-2012) and Edwin “Buzz” Aldrin (1930-) became the first humans ever to land on the moon. The duo collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth. For years, scientists have tossed out several theories about the moon based on science more than philosophy. The Apollo missions and subsequent moon landings have been at the center of controversy and conspiracy for years.
The moon is often summarized as a part of the earth as it is believed it was created during the initial formation of the planet. It is a source of cosmic phenomena that reflects the light of the sun during night hours and is probably the base of all missions to Mars and beyond. On November 14, 1969, 2 months later the Apollo 11 mission, Kennedy Space Centre Florida launched Apollo 12, another man mission to the moon. This mission’s key objective was to study what’s inside the moon rather than what’s outside.
Is the moon hollow from the inside?
One of the most popular lunar mysteries is what’s actually inside the surface of the moon. During the Apollo missions, NASA astronauts worked to detect what lies beneath the lunar surface of the moon and they placed seismic recording devices on the surface to document how the moon behaves during artificial or natural moonquakes. For this, they strike man-made explosions and crash landings of Apollo Rockets. The astronauts were provided with a series of ALSEPs (Apollo Lunar Surface Experiment Packages) to set up seismographs and initiate detonations ranging from a gunshot to multiple grenades. Eventually, NASA intentionally crash-landed the Apollo 12 module as well as the S-IVB rocket setting off an explosive force equivalent to nearly 12 tons of TNT.
The scientists on the earth further decoded the seismic data. But what they recorded was beyond anyone’s expectation. The signal seemed to be going back and forth inside the moon almost sounded like a ringing bell, reverberating sometimes for hours at a time. This suggested that the moon’s density was clearly less than earth leaving NASA and the Apollo astronauts surprised. This discovery came as a shock and opened the door to further moon theories.
Some people theorized that the moon could be hollow from the inside due to the fact that it rang like an alarm clock and so its structure is not like earth as scientists previously expected. Because ‘ringing like a bell’ doesn’t make any sense if the moon was solid from inside, there must be vast empty spaces inside the moon where the sound waves reverberate around for such a long time.
The experiment on Apollo 17 called Chapel Bell conducted back on November 20, 1969, was a classified mission that nobody knows about. Even 50 years later, that experiment is still classified which implies that the results of that particular mission were something extraordinary or unusual that NASA does not want people to know about. Or could have it provided evidence to suggest that the moon was hollow from the inside? But this again raises the question of ‘how’ as a hollow planetary body cannot be made hollow unless an external source intervened. And if the moon is actually hollow it meant it’s not a naturally occurring phenomenon, it got to be artificial or it was intentionally placed inside the earth’s orbit.
Additionally, the craters on the surface of the moon are thought to be the result of meteorite impacts, which meant there should be a certain proportion between their depth and width. Yet, many wider craters have similar depths to narrower craters, with some even appearing convex, and when astronauts attempted to drill into the craters artificially, they were barely able to penetrate the surface, discovering processed metals like brass, mica, and pure titanium.
Though the idea that the moon could be hollow does not really fit with mainstream science. Because if it is an artificial space station, who would have placed it there especially considering the size of the moon? There has to be some kind of explanation or a bigger story. NASA scientists have theorized that the bell-like sound came from the low level of water in the moon’s crust. On the moon, there is very little water on the surface and interior of the moon; and because the water absorbs vibration quickly, it might have sounded the way it did.
Thus, the idea of a hollow moon still remains science fiction.
