Here’s what a Black Hole sounds like, according to internet users

Since 2003, the black hole at the centre of the Perseus galaxy cluster has been linked to sound. Scientists discovered that pressure waves from the black hole rippled up and down in a heated gas cloud, producing a note 57 octaves below middle C, which is beyond human hearing range. Earth is 240 million light-years away from the Perseus galaxy.

This black hole sound machine can now produce a wider range of tones thanks to a new sonification. A new sonification was made available as part of NASA’s Black Hole Week events this year.

This sonification is unlike any other that has been done before (1, 2, 3, 4) in several ways because it revisits genuine sound waves identified in data from NASA’s Chandra X-ray Observatory.

Using sound waves previously identified by astronomers but never heard before, a new sonification of Perseus has been created. A new sonic representation of another well-known black hole has also been revealed. The video that Chandra Observatory shared on Twitter has been viewed by over 161,000 people.

The common belief that there is no sound in space stems from the fact that much of space is effectively a vacuum, preventing sound waves from propagating. However, a large amount of gas surrounds a galaxy cluster, allowing sound waves to pass through it without interference.

The black hole’s eerie noises terrified internet users, and others claimed to see a skull in the footage. Several Twitter users have commented that it sounds like music from a horror film.

Patterns of behaviour that emerge after trauma

Patterns of behaviour that emerge after trauma

Trauma is a deeply distressing or disturbing experience that can leave a lasting impact on a person’s mental and emotional health. It can result from a range of events, such as natural disasters, accidents, physical or emotional abuse, or military combat. Trauma can have a significant effect on a person’s behavior and can manifest in various ways. Here are some patterns of behavior that often emerge after trauma:

  1. Hyperarousal: After experiencing trauma, a person may feel constantly on edge, with heightened levels of anxiety and tension. This can manifest as irritability, restlessness, and difficulty sleeping.
  2. Avoidance: Trauma can also cause a person to avoid situations, people, or places that remind them of the traumatic experience. This can lead to social withdrawal, isolation, and a loss of interest in previously enjoyable activities.
  3. Emotional numbness: Trauma can cause a person to feel emotionally disconnected or numb, making it difficult for them to experience positive emotions such as joy or love.
  4. Hypervigilance: A person who has experienced trauma may be hyper-aware of their surroundings and perceive threats where none exist. This can lead to an increased sense of danger, which can trigger anxiety or panic attacks.
  5. Flashbacks: Trauma can cause a person to experience vivid and intrusive memories of the traumatic event. These flashbacks can be triggered by a range of stimuli, such as sights, sounds, or smells.
  6. Guilt and shame: Trauma can cause a person to experience feelings of guilt, shame, and self-blame. They may feel responsible for what happened to them, even when it was beyond their control.
  7. Substance abuse: Trauma can lead to the use of drugs or alcohol as a way of coping with difficult emotions. This can quickly become a self-destructive pattern of behavior that exacerbates the trauma.

It’s important to note that not everyone who experiences trauma will display all of these behaviors, and that each person’s response to trauma is unique. However, recognizing these patterns of behavior can help individuals and their loved ones identify when trauma may be a contributing factor to mental and emotional health challenges. Seeking professional support, such as therapy or counseling, can help individuals process their trauma and learn healthy coping mechanisms to manage their behavior.
