Moon Landing - it is real or fake?

Is moon landing real or fake? This is a question that has been nagging in people’s heads for years upon years. According to an article written by Space.com, it is a hoax that has been spreading like a wildfire on the internet for over 50 years, after Apollo 11 took place. For those who aren't familiar, Apollo 11 was the first mission to land on the moon. 

 

One example of this ongoing argument is from back in February of 2001, when Fox Broadcasting released a documentary called, “Conspiracy Theory: Did We Land On The Moon?”, in which a man named Phil Plait worked tirelessly, doing everything he possibly could to prove that, yes, Moon Landing is in fact real.  

 

Plait has stated that he wished that the documentary had never aired. He has said, “ ...it opened a huge Pandora’s box. On the other hand, it’s exposing a wound to sunlight. That thing was there anyway, festering. Let it get out to the public, and let it heal, and let it kill the infection.”  

 

Even though people were, and still are, extremely skeptical of moon landing, people are well aware that astronauts such as Neil Armstrong had stepped on the moon on July 20th, 2”1969. For example, the movie, “Diamonds Are Forever” featuring James Bond, even made a comment about fake moon landings, when it hit the big screen two years later, in 1971. 

Another article that I had looked at was by The Rolling Stones, which gives us a quick overlook of the history of conspiracy theories about moon landing. The article starts out by saying, “the moon is weird,” which, yes, I would agree in some cases. Another statistic that it gives us is the fact that only 12 people have actually been to the moon of all mankind, which is so crazy to think about as it seems like so much more.  

 

Some examples of people’s uneducated opinions include: 

 

  1. The moon is made of cheese. 

  1. Women’s menstrual cycles are affected by the lunar cycle. 

 

Both of these things are almost hilariously inaccurate.  

 

The third and final article I will be looking at is by the Washington Post. In the title, it mentions that theorists are still “howling” at the “moon hoax.” The first small paragraph of this article, which was written back in 2019, mentions that the President-at-the-time, Donald Trump, had ordered Nasa to put astronauts back on the moon by the year 2024.  

 

In this article , one of the main points says that, “None of this will change the minds of people who live in a parallel belief universe where NASA faked the Apollo Moon landings.” - Confusing much? Because of the times in which we are living now, people are much more gullible to falling for conspiracy theories and rumours. So much so, that even a topic such as this can have people going at each other over literal nonsense.  

The mystery of dark matter

Wondering what space is made of? Well, so is everyone else.

It all started with Swiss astronomer Fritz Zwicky in 1933. He was measuring the speed at which the Coma galaxy cluster spun and noticed that the cluster was moving at a speed that implied much more mass than what was visible. Zwicky theorized there was some sort of “missing mass” keeping the galaxies from escaping the cluster’s gravitational pull.

In the 1970s, American astronomer Vera Rubin and her colleagues confirmed Zwicky’s theory. They observed that the mass of the stars within an average galaxy is only about 10 percent of what is required to keep those stars orbiting the galaxy’s centre.

Thus, the mystery of dark matter was born.

Composition

But what is all this “missing mass”? Space fog? Alien interference? Billions of tonnes of invisible primordial soup, the first ever forbidden snack? Maybe.

The truth is, we know more about what dark matter is not than what it is.

The first thing we know is that it isn’t visible to the eye. Dark matter is, well… dark. Its presence is detected by its gravitational pull rather than its luminosity or its ability to reflect light. This means that scientists need to get creative when it comes to measuring dark matter (but I’ll get to that later).

It also isn’t antimatter. Dark matter doesn’t produce the unique gamma rays antimatter does when it collides with regular matter.

Finally, it is not the same as the dark clouds of matter in and between galaxies. These gases are made up of baryons (protons, neutrons and the like), familiar and recognizable to any scientist with a degree in astrophysics. But a common belief is that dark matter isn’t baryonic at all. Instead, it’s assumed to be made up of particles that exist in theory but have yet to be observed.

That’s a longer way of saying we have no idea what this stuff is made of.

Measurement

It’s later, and now is the time to talk about measuring dark matter!

Scientists can indirectly measure dark matter through a method called gravitational lensing. Like with optical lenses, light passing through a gravitational lens gets bent, not unlike myself when I advise my brother to put anything but hot sauce on his vegetables.

When light from distant stars passes through a galaxy, the gravity of the matter in that galaxy causes the light to bend. As a result, the light looks like it’s coming from somewhere other than its actual origin. Many NASA scientists use the Hubble Space Telescope to observe the amount of bending to learn about the dark matter present in a certain galaxy or cluster.

Theories

There are no small number of theories surrounding dark matter, but I’ll only cover some of the major ones.

Dark matter could be brown dwarfs—stars that never ignited because they lacked the necessary mass. Or maybe the remnants of the cores of dead small or medium sized stars, called white dwarfs. Dark matter might even be neutron stars, or giant galaxy-sized black holes, or literally magic.

Okay, probably not that last one.

The issue with those theories is that there just aren’t enough failed or dead stars to account for the amount of dark matter in the universe.

Dark matter makes up roughly 30 percent of the universe’s matter-energy composition (literally everything in the universe). I mean, that’s a substantial percentage, but it’s not that much, right? It may seem that way until you learn that everything on Earth and everything NASA has ever observed with all their fancy telescopes adds up to less than 5 percent of the universe. What a way to make you feel small.

The rest of the composition is dark energy, but that’s a whole other can of worms.

Conclusion

To this day, the nature of dark matter remains one of the greatest astronomical mysteries. Despite being aware of it for nearly a century, we know very few things about dark matter that aren’t (at least in part) theoretical. All we know for sure is that it’s there, and it’s keeping all those really pretty galaxies together. Everyone say thank you, dark matter!
