I do the relativistic math behind Project Hail Mary — time dilation, mass ratios, coast phases, and the relativsitic rocket equation with astrophage. How long would it take to reach Alpha Centauri, Tau Ceti, Betelgeuse, Andromeda, and the edge of the observable universe under constant 1.5G acceleration? We also look at Andy Weir’s mass ratio mistake, the astrophage infection range problem, and visualize the spread using the AT-HYG stellar catalog. Includes a interactive relativistic travel calculator on my website.

The Aliens and Spaceships of Project Hail Mary (Explained)

With the movie project hail mary just out a few days back, we are here to discuss the alien species and the spaceships that appeared in the movie. If you have seen the trailer, you would know what Rocky is, but here we will discuss in detail about his species and two others that are key to the story.

Scientists observe atoms existing in two places at once for the first time

In a world-first, quantum physicists at ANU have observed atoms entangled in motion. Their experiment using helium atoms, represents a major advancement on similar experiments using photons, which are particles of light.

But unlike photons, helium atoms have mass and experience gravity.

By observing quantum entanglement in atoms for the first time, are we one small step closer to finding out whether the “Theory of Everything” is not just hot air?

Black Holes May Not Be What We Thought

Brian Greene and physicist Samir Mathur explore one of the deepest puzzles in modern physics, the true nature of black holes and the fate of information in the universe.

Their conversation centers on the black hole information paradox, a problem that has challenged physicists for decades. If quantum mechanics says information can never be destroyed, how can black holes once thought to erase everything that falls into them be reconciled with that principle? Mathur introduces the fuzzball theory, a proposal from string theory suggesting that black holes are not empty regions but complex structures that preserve information.

Greene and Mathur also revisit key developments in black hole physics, from entropy and Hawking radiation to modern ideas like firewalls and wormholes. They reflect on why certain approaches may fall short and whether recent theoretical insights are bringing the paradox closer to resolution. This conversation offers an engaging look at how physicists are rethinking black holes, quantum gravity, and the fundamental structure of reality.

This program is part of the Rethinking Reality series, supported by the John Templeton Foundation.

Participant: Samir Mathur.
Moderator: Brian Greene.

Wristband enables wearers to control a robotic hand with their own movements

Massachusetts Institute of Technology (MIT) engineers have developed an ultrasound wristband that precisely tracks hand movements in real-time for robotics and virtual reality control.

The next time you’re scrolling your phone, take a moment to appreciate the feat: The seemingly mundane act is possible thanks to the coordination of 34 muscles, 27 joints, and over 100 tendons and ligaments in your hand. Indeed, our hands are the most nimble parts of our bodies. Mimicking their many nuanced gestures has been a longstanding challenge in robotics and virtual reality.

Now, MIT engineers have designed an ultrasound wristband that precisely tracks a wearer’s hand movements in real-time. The wristband produces ultrasound images of the wrist’s muscles, tendons, and ligaments as the hand moves, and is paired with an artificial intelligence algorithm that continuously translates the images into the corresponding positions of the five fingers and palm.

Weight Changes With Tirzepatide and Concomitant Weight-Inducing Medications: Post Hoc Analysis of Randomized Clinical Trials

In three RCTs, Tirzepatide was associated with clinically meaningful weight loss among adults with overweight or obesity, even when concomitant weight-inducing medications were initiated during treatment.

Question What is the association between tirzepatide and weight reduction among patients with overweight or obesity who initiated concomitant weight-inducing medications?

Findings In this post hoc analysis of participants in the SURMOUNT-1,-3, and-4 trials receiving at least 1 concomitant weight-inducing medication (17.3%-20.0%), tirzepatide treatment was associated with comparable weight loss to the primary study results.
