The Kardashev Scale has become a standardized way of classifying (hypothetical) advanced civilizations. The lowest rank, Type 1, is still way ahead of us — but by how much? When will we achieve Type 1 status and exactly how could we plausibly do so? In this video, we go through some estimates of when humanity might become Type 1, and in particular what kind of energy sources we could harness to achieve this feat.

Backwards through time? We travel forwards every day, but traveling back could let us change our past, visit old friends, or manipulate the timeline to our benefit… Although our knowledge of space and time remains incomplete, we can still use what we know to consider possible time machines. But what kind of paradoxes would this entail and how can we resolve them? Join us today on a special journey through time.

An educational video written and presented by Professor David Kipping.

The Rare Earth Hypothesis suggests that our planet may the product of an incredibly improbable sequence of events, and thus perhaps intelligent life is extremely rare in the cosmos. Here we tackle this highly influential idea and the arguments behind it. But, digging deeper, we’ll uncover some problems with the Rare Earth idea — some of which strike to the very core of our scientific quest.

Black holes are known as the most terrifying, mysterious, and fascinating objects in the Universe. Eternally hungry, they eat everything in their path and are constantly expanding. But how small and how big can a black hole be? Unlike stars and planets, black holes have no size restrictions. They grow when they eat the matter around them. Does it mean that they can be not only super large but super small? Let’s find out!

“Our goals were to explore the new sound world created by using new materials”

Only musicians can understand how grueling and challenging it is to play the violin. Violins, even mediocre ones, are worth thousands of dollars. Good news for music students and beginners, they will meet with low-cost and durable 3D-printed violins thanks to The Acoustical Society of America’s AVIVA Young Artists Program.

As stated in the release, today in Nashville, Mary-Elizabeth Brown, director of the AVIVA Young Artists Program discussed the steps taken and the lessons learned in her presentation, Old meets new: 3D printing and the art of violin-making.

Shawn Peters.

The team’s inspiration roots in multiple places, said Brown. Our goals were to explore the new sound world created by using new materials, to leverage the new technology being used in other disciplines, and to make music education sustainable and accessible through the printing of more durable instruments.

Summary: A new musical app takes listeners on an emotional “rollercoaster ride”, leaving them in a more positive emotional a focused state than when they first started listening to the soundtrack.

Source: Acoustical Society of America.

Music has the potential to change emotional states and can distract listeners from negative thoughts and pain. It has also been proven to help improve memory, performance, and mood.

AI generated video I created with stable diffusion by using prompts that I used to generate AI art based on the themes in the song. I tried midjourney, disco diffusion, and settled in deforum in stable diffusion to create this AI generated music video. stable diffusion AI art is so much fun.
