“Space: Above and Beyond” was a short-lived but critically acclaimed military science fiction series that aired on Fox from 1995 to 1996. Created by James Morrison and Glen Morgan, the show was set in the year 2063 and followed a group of Marine pilots as they fought in an intergalactic war against an alien threat known as the “Chigs.” Despite its loyal fan base and positive reviews, the show was cancelled after only one season due to low ratings. The series had a unique blend of action, drama, and social commentary, exploring themes such as war, sacrifice, and the human condition. The show’s creators drew inspiration from classic war movies and literature, including “Apocalypse Now” and “All Quiet on the Western Front.” The characters were complex and well-developed, with rich backstories and motivations that added depth to the storylines. One of the reasons “Space: Above and Beyond” has endured despite its short run is its influence on later science fiction series. The show’s blend of military action and sci-fi elements can be seen in later series such as “Battlestar Galactica” and “Stargate SG-1.” The show’s exploration of complex themes and issues also paved the way for more cerebral science fiction series like “Westworld” and “Black Mirror.” Despite its influence and loyal fan base, “Space: Above and Beyond” remains a largely forgotten series. The show’s cancellation and lack of syndication have made it difficult for new viewers to discover, and it has largely been lost to time. However, with the rise of streaming services and online archives, it is possible for fans to rediscover and reappreciate this groundbreaking series. It’s a shame that “Space: Above and Beyond” is not more widely recognized or celebrated, given its influence on the science fiction genre and its thought-provoking storylines. The show’s exploration of complex themes and issues, combined with its unique blend of action and drama, make it a compelling and engaging watch. As the 30th anniversary of the show’s premiere approaches, it’s time to rediscover and reappreciate this forgotten classic of science fiction television.

The moon is indeed slowly moving away from the Earth at a rate of about $3.8$ centimeters per year. This phenomenon is primarily caused by the tidal interactions between the Earth and the moon. The moon’s gravity causes the Earth’s oceans to bulge, creating two tidal bulges: one on the side of the Earth facing the moon and the other on the opposite side. The gravity of the Earth then pulls on these bulges, slowing down the Earth’s rotation. This process is known as tidal acceleration. As the Earth’s rotation slows down, the length of its day increases. About $620$ million years ago, the length of a day on Earth was only about $21.9$ hours. The slowing down of the Earth’s rotation has a secondary effect: it causes the moon to move away from the Earth. The reason for this is due to the conservation of angular momentum in the Earth-moon system. As the Earth’s rotation slows down, the angular momentum of the Earth-moon system must be conserved. This is achieved by increasing the distance between the Earth and the moon, which in turn increases the angular momentum of the moon’s orbit. In addition to tidal interactions, the moon’s orbit is also affected by the Earth’s slightly ellipsoidal shape. The Earth is not a perfect sphere, and its equatorial radius is about $6,378$ kilometers, while its polar radius is about $6,357$ kilometers. This ellipsoidal shape causes a small torque on the moon’s orbit, which also contributes to the moon’s recession from the Earth. It’s worth noting that the rate at which the moon is moving away from the Earth is not constant and can vary slightly over time due to various geological and astronomical processes. However, on average, the moon’s distance from the Earth increases by about $3.8$ centimeters per year. This gradual increase in the moon’s distance from the Earth has significant implications for the Earth-moon system’s evolution. In about $50$ billion years, the moon will have moved far enough away from the Earth that it will no longer be able to stabilize the Earth’s axis, which could lead to drastic changes in the Earth’s climate. However, by that time, the sun will have already exhausted its fuel and become a red giant, making the Earth’s climate uninhabitable anyway.

You’re highlighting the importance of decolonizing space exploration and promoting a more inclusive and diverse approach to naming and exploring celestial bodies. This is a timely and crucial discussion, as space exploration continues to expand and become more global.

The use of colonial language in space exploration has indeed been dominant, with many celestial bodies and features named after Western explorers, scientists, and mythological figures. While these names may have been chosen to honor the achievements of these individuals, they also perpetuate a narrative that erases the contributions and perspectives of non-Western cultures.

There are several issues with the dominant use of colonial language in space exploration:

  1. Erasure of indigenous cultures: The use of colonial language ignores the rich cultural heritage and astronomical knowledge of indigenous communities, who have been observing and naming celestial bodies for centuries.
  2. Lack of diversity: The dominance of Western names and terminology limits the representation of diverse cultures and languages, perpetuating a Eurocentric view of the universe.
  3. Inaccurate representation: Colonial language often imposes a Western perspective on non-Western cultures, leading to inaccurate or misleading representations of their astronomical knowledge and traditions.

To create a more inclusive and diverse approach to space exploration, we can consider the following strategies:

  1. Incorporate indigenous knowledge: Collaborate with indigenous communities to learn about their astronomical traditions and incorporate their knowledge and perspectives into space exploration.
  2. Use diverse languages and terminology: Adopt a more inclusive approach to naming celestial bodies and features, using languages and terminology from diverse cultures and regions.
  3. Promote cultural exchange and representation: Encourage international cooperation and cultural exchange in space exploration, ensuring that diverse cultures and languages are represented and valued.
  4. Develop new naming conventions: Establish new naming conventions that reflect the diversity of human culture and experience, avoiding the perpetuation of colonial language and perspectives.

Some examples of efforts to decolonize space exploration include:

  1. The International Astronomical Union’s (IAU) naming conventions: The IAU has established guidelines for naming celestial bodies and features, which include the use of names from diverse cultures and languages.
  2. The NASA’s Indigenous Peoples’ Advisory Committee: NASA has established an advisory committee to ensure that indigenous perspectives and knowledge are considered in space exploration and education.
  3. The African Astronomical Society’s (AAS) naming initiative: The AAS has launched an initiative to name celestial bodies and features using African languages and terminology.

By promoting a more inclusive and diverse approach to space exploration, we can create a more equitable and representative field that values the contributions and perspectives of all cultures and communities.

The Trump team’s backing of an unproven drug for autism has sparked controversy and debate. The drug in question is a type of antibiotic called suramin, which has been touted as a potential treatment for autism spectrum disorder (ASD). However, it’s essential to examine the available evidence and separate fact from fiction. Suramin has been used to treat various diseases, including river blindness and sleeping sickness, but its use in autism treatment is still largely experimental. Some proponents of suramin claim that it can help alleviate symptoms of autism, such as social anxiety and repetitive behaviors, by reducing inflammation and modulating the gut-brain axis. However, numerous experts and organizations, including the Autism Society and the American Academy of Pediatrics, have expressed concerns about the lack of robust scientific evidence supporting suramin’s use in autism treatment. The majority of studies on suramin and autism are small, poorly designed, and have methodological limitations, making it challenging to draw conclusive findings. A 2017 study published in the Annals of Clinical and Translational Neurology found that suramin improved symptoms of autism in a small group of children, but the study had significant limitations, including a small sample size and lack of control group. Other studies have reported mixed or inconclusive results, and some have raised concerns about the potential risks and side effects of using suramin in children with autism. The FDA has not approved suramin for the treatment of autism, and the agency has warned against its use due to potential risks, including neuropathy, kidney damage, and other adverse effects. Additionally, the use of suramin in autism treatment is not supported by mainstream medical organizations, and many experts consider it an unproven and potentially harmful therapy. In conclusion, while some individuals and organizations may claim that suramin is an effective treatment for autism, the current scientific evidence does not support its use. The Trump team’s backing of suramin is not based on robust scientific evidence, and it’s crucial to approach this topic with a critical and nuanced perspective, prioritizing the well-being and safety of individuals with autism. More research is needed to fully understand the potential effects of suramin on autism, and any claims about its effectiveness should be treated with skepticism until proven otherwise.

Sneezing can be triggered by various factors, including allergens from cats, dust, and other environmental factors. Allergens from cats are primarily found in their dander, saliva, and urine, which can become airborne and be inhaled, causing allergic reactions in sensitive individuals. Similarly, dust is a common allergen that can trigger sneezing, congestion, and other respiratory issues. Regarding the use of UV light to neutralize allergens, it’s true that certain types of UV light have been shown to be effective in reducing or eliminating allergens from surfaces and the air. UV-C light, in particular, has been found to be effective in neutralizing allergens, including those from cats and dust, in a matter of minutes. UV-C light works by damaging the DNA of microorganisms, including bacteria, viruses, and other pathogens, making it impossible for them to reproduce and cause harm. This same principle can be applied to allergens, where UV-C light can break down the proteins that cause allergic reactions, rendering them harmless. However, it’s essential to note that not all UV light is created equal, and some types of UV light can be harmful to humans and animals. UV-A and UV-B light, for example, can cause skin damage, eye problems, and even cancer. Therefore, it’s crucial to use a safe and specifically designed UV-C light device that emits a wavelength of around 254 nanometers, which is effective against allergens but safe for humans and animals. It’s also important to remember that while UV-C light can be an effective tool in reducing allergens, it’s not a substitute for regular cleaning, dusting, and vacuuming. These habits are still essential for maintaining a clean and healthy environment, especially for individuals with allergies. In summary, sneezing can be triggered by various allergens, including those from cats and dust. Safe UV-C light can be an effective tool in neutralizing these allergens in minutes, but it’s crucial to use a specifically designed device that emits a safe wavelength. Additionally, regular cleaning and maintenance are still necessary to maintain a healthy environment.
