Is space continuous or discrete?

Posted by in categories: physics, space

We’re used to thinking of space as continuous.

A stone can be anywhere in space. It can be here. Or it can be an inch to the left. Or it can be half an inch further to the left. Or it can be an infinitesimal fraction of an inch even further to the left. Space is infinitely divisible.

Physicist believes that the entire universe could be a neural network

Posted by in category: robotics/AI

However, a physics professor at the University of Minnesota Duluth named Vitaly Vanchurin attempted to reframe reality in a particularly eye-opening way in a preprint published on arXiv, arguing that we’re living inside a huge neural network that governs everything around us.

New Tech Can See People Through Walls Using WiFi

Posted by in categories: information science, internet, mapping, robotics/AI

A team of researchers have come up with a machine learning-assisted way to detect the position of shapes including the poses of humans to an astonishing degree — using only WiFi signals.

In a yet-to-be-peer-reviewed paper, first spotted by Vice, researchers at Carnegie Mellon University came up with a deep learning method of mapping the position of multiple human subjects by analyzing the phase and amplitude of WiFi signals, and processing them using computer vision algorithms.

“The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input,” the team concluded in their paper.

Transplanting a Gene Common in Centenarians Could Rewind The Heart’s Age

Posted by in categories: biotech/medical, life extension

Age catches up with us all eventually, but in some people the right genes can make that chase into our twilight years a relatively leisurely one.

A few years ago Italian researchers discovered something special about people who live well into their 90s and beyond: they commonly have a version of a gene called BPIFB4 that protects against cardiovascular damage and keeps the heart in good shape for a longer period of time.

By introducing the mutated gene into older mice, the scientists have now seen how the variant rewinds markers of biological heart aging by the equivalent of more than 10 human years.

Physicists want to use gravitational waves to ‘see’ the beginning of time

Posted by in category: physics

Gravitational waves are ripples in the fabric of space. Waves that originated in the early universe could carry important information about the phenomena that occurred there.
