What is the viewing experience of VR porn really like?

Recent studies suggest virtual reality porn can produce a more positive experience than viewing from a monitor or screen.

  • Since early 2014 when Ela Darling, an adult entertainment actress recorded her first VR performance, the world of virtual porn has taken off.
  • Recent studies suggests VR porn produces a more positive experience than typical porn viewing through a monitor or screen.
  • RealityLovers, a top VR porn website, speaks about the benefits of virtual reality porn experiences and the future of VR adult entertainment.

  • Hypnosis refers to a trance state that is characterized by extreme suggestibility, relaxation, and heightened imagination.
  • According to a Stanford University School of Medicine study, there are three areas of our brains that change during a state of hypnosis.
  • This groundbreaking study provides information on how hypnosis impacts the brain, which could lead to new and improved pain management and anxiety treatments in the future.

The mental and physical health benefits of ecotherapy

There are countless studies that prove ecotherapy (often referred to as nature therapy) is beneficial for your physical and mental health.

  • What was once considered a simple practice and ideology about the benefits of nature has been proven in multiple studies to positively impact our physical and mental health.
  • Some of the benefits of spending time in nature can be: a boost in killer-cells that fight off viruses, an ability to maintain focus and improvement in mental health conditions such as anxiety, depression and other mood disorders.
  • To explain the all-encompassing benefits of nature, the Japanese have coined the term "shinrin yoku", which translates to "forest bathing."

Are we living in a simulation?

Is this the real life, or is this just fantasy?

  • Elon Musk famously believes we're living in a simulation, that constant technological improvement means we could be trapped inside a video game console created by a more advanced civilization.
  • In this video, Bill Nye, CEO of The Planetary Society, Joscha Bach and Donald Hoffman, both cognitive psychologists, all weigh in on whether this is base reality or a realistic fiction.
  • What insight from these three thinkers gets your mind ticking? Let us know in the comments! We're stunned at the thought that, if this is a simulation, humans might not be the central purpose of it; we may be an accident of a larger experiment.

This is what aliens would 'hear' if they flew by Earth

A Mercury-bound spacecraft's noisy flyby of our home planet.

  • There is no sound in space, but if there was, this is what it might sound like passing by Earth.
  • A spacecraft bound for Mercury recorded data while swinging around our planet, and that data was converted into sound.
  • Yes, in space no one can hear you scream, but this is still some chill stuff.

First off, let's be clear what we mean by "hear" here. (Here, here!)

Sound, as we know it, requires air. What our ears capture is actually oscillating waves of fluctuating air pressure. Cilia, fibers in our ears, respond to these fluctuations by firing off corresponding clusters of tones at different pitches to our brains. This is what we perceive as sound.

All of which is to say, sound requires air, and space is notoriously void of that. So, in terms of human-perceivable sound, it's silent out there. Nonetheless, there can be cyclical events in space — such as oscillating values in streams of captured data — that can be mapped to pitches, and thus made audible.

BepiColombo

The European Space Agency's BepiColombo spacecraft took off from Kourou, French Guyana on October 20, 2019, on its way to Mercury. To reduce its speed for the proper trajectory to Mercury, BepiColombo executed a "gravity-assist flyby," slinging itself around the Earth before leaving home. Over the course of its 34-minute flyby, its two data recorders captured five data sets that Italy's National Institute for Astrophysics (INAF) enhanced and converted into sound waves.

Into and out of Earth's shadow

In April, BepiColombo began its closest approach to Earth, ranging from 256,393 kilometers (159,315 miles) to 129,488 kilometers (80,460 miles) away. The audio above starts as BepiColombo begins to sneak into the Earth's shadow facing away from the sun.

The data was captured by BepiColombo's Italian Spring Accelerometer (ISA) instrument. Says Carmelo Magnafico of the ISA team, "When the spacecraft enters the shadow and the force of the Sun disappears, we can hear a slight vibration. The solar panels, previously flexed by the Sun, then find a new balance. Upon exiting the shadow, we can hear the effect again."

In addition to making for some cool sounds, the phenomenon allowed the ISA team to confirm just how sensitive their instrument is. "This is an extraordinary situation," says Carmelo. "Since we started the cruise, we have only been in direct sunshine, so we did not have the possibility to check effectively whether our instrument is measuring the variations of the force of the sunlight."

When the craft arrives at Mercury, the ISA will be tasked with studying the planets gravity.

Magentosphere melody

The second clip is derived from data captured by BepiColombo's MPO-MAG magnetometer, AKA MERMAG, as the craft traveled through Earth's magnetosphere, the area surrounding the planet that's determined by the its magnetic field.

BepiColombo eventually entered the hellish mangentosheath, the region battered by cosmic plasma from the sun before the craft passed into the relatively peaceful magentopause that marks the transition between the magnetosphere and Earth's own magnetic field.

MERMAG will map Mercury's magnetosphere, as well as the magnetic state of the planet's interior. As a secondary objective, it will assess the interaction of the solar wind, Mercury's magnetic field, and the planet, analyzing the dynamics of the magnetosphere and its interaction with Mercury.

Recording session over, BepiColombo is now slipping through space silently with its arrival at Mercury planned for 2025.
