Scientists Say There May Be a “Mirror World” to Our Own

Posted by in categories: physics, space

Three researchers published their findings this week in the journal Physical Review Letters and say their hypothesis is based on problems with the Hubble Constant, the rate at which the universe expands. Yesterday’s SciTechDaily report on the study says predictions for that constant are a lot slower than what we’ve measured in reality, and scientists are trying to figure out what’s causing the discrepancy. They say the cause could be a mirror world we can’t yet see.

“This might provide a way to understand why there appears to be a discrepancy between different measurements of the Universe’s expansion rate,” researchers said in a statement about their findings.

Scientists have long built models of the cosmos. Now the task is to create one that doesn’t violate any of the rules cosmological rules we’ve learned so far. The researchers say that if the universe is somehow exploiting what we know about its physics and symmetry there could be an invisible mirror world very similar to ours but invisible except through gravitational impact on our world.

China will soon launch a huge space telescope with a 2.5 billion-pixel camera

Posted by in category: space

China’s first large space telescope could launch as soon as 2023. The new telescope will be called the Chinese Space Station Telescope. It will be roughly comparable to NASA’s long-standing Hubble Space Telescope, though its field of view will be somewhat larger.

China has been making big moves when it comes to space exploration. In 2021, the nation placed the first components of its new space station in orbit. Then, earlier this year, it shared plans to build an asteroid monitoring system. Now, it wants to put a telescope in space.

A theory of consciousness from a theoretical computer science perspective: Insights from the Conscious Turing Machine

Posted by in categories: robotics/AI, science

This paper provides evidence that a theoretical computer science (TCS) perspective can add to our understanding of consciousness by providing a simple framework for employing tools from computational complexity theory and machine learning. Just as the Turing machine is a simple model to define and explore computation, the Conscious Turing Machine (CTM) is a simple model to define and explore consciousness (and related concepts). The CTM is not a model of the brain or cognition, nor is it intended to be, but a simple substrate-independent computational model of (the admittedly complex concept of) consciousness. This paper is intended to introduce this approach, show its possibilities, and stimulate research in consciousness from a TCS perspective.

Elon Musk: If You Don’t Think AI Could Outsmart You, You’re an Idiot

Posted by in categories: Elon Musk, robotics/AI


“I’ve been banging this AI drum for a decade,” Musk told Business Insider.

Musk’s latest warning is that smart people who assume they could never be fooled by a machine are in effect lowering their guard to any AI trickery coming their way.

NASA InSight shutting down and more: Understand the world through 9 images

Posted by in category: cosmology

NASA is being forced to end its Mars lander mission early because of dust.

NASA’s InSight Mars lander is shutting down after four years and scientists have seen our galaxy’s black hole for the first time. Here’s May 11–18 in science images.

Meta won’t build a dedicated metaverse after all, exec says

Posted by in category: futurism

An interesting development, you could say revision, or even a back-tracking on the vision for just what it is that Meta plans to build, eventually.

I think it’s important to keep in mind, despite the excitement, that these technologies are still experimental in many ways, they take time to develop, and they will change. Keeping this in mind can help to temper our expectations, but also to spot the hype.
