Scientists Move Over: AIs Predict Research Results Without Doing Research
Backreaction

13h ago
Scientific literature is growing rapidly, meaning scientists are increasingly unable to keep up with all of the latest developments in research. AI large language models, though, can read and “digest” information much more quickly than their human counterparts, making them the perfect tools to conduct massive literature reviews. Recent research shows they’re also very accurate at predicting the ..read more

What Would Change with a “New Physics” Breakthrough?
Backreaction
by Sabine Hossenfelder
3d ago
“New physics” is a catch-all term for fundamentally new discoveries in physics (such as dark matter, quantum gravity, or a theory of everything) which push the boundaries of how we understand our reality. How could new discoveries in these areas of research affect our lives? Let’s take a look at what knowledge and practical use we could potentially gain ..read more

New Study Deepens Mystery of Life’s Origin
Backreaction

Scientists believe that all life on Earth originated from one single organism, the Last Universal Common Ancestor, LUCA. Now, researchers have uncovered evidence that LUCA was much more complex than previously thought, which is puzzling because it didn’t have a lot of time to evolve. This seems to suggest that life can come into being much faster than we thought. Let’s take a look ..read more

Theory of Everything Predicts New Physics For Supermassive Black Holes
Backreaction
by Sabine Hossenfelder
6d ago
Mathematician Stephen Wolfram has attempted to develop a theory of everything using hypergraphs, which are essentially sets of graphs that can describe space-time. Recently, another mathematician named Jonathan Gorard has used hypergraphs to describe what happens if a black hole accretes matter. He claims that evidence for hypergraphs should be observable in the energy that is emitted during the ..read more

Moore’s Law is So Back

According to Moore’s law, the number of transistors on a microchip should double every year. Two years ago, Nvidia CEO Jensen Huang said that the law was “dead” because we're hitting physical limits for the miniaturization of transistors. Now, though, he’s reversed that claim, instead predicting that we're about to see a “Hyper” Moore’s law. Let’s take a look ..read more

Quantum Tech Could Be Used in Warfare, Scientists Warn.
Backreaction

Physics, as history taught us, can be dangerous. As quantum computing continues to progress (slowly), researchers and governments across the world are worried that the technology will be used for evil purposes. Why? And should we really be worried about quantum tech? Let’s take a look ..read more

The Crisis in Cosmology Just Got So Much Worse
Backreaction
by Sabine Hossenfelder
1w ago
In the past decade, astrophysicists have found a lot of evidence that our large-scale theory for how the universe works has some large-scale problems as well. It has, however, remained controversial whether this is a problem with data collection or whether it is indeed a problem with our understanding of the universe. In a new paper, astrophysicists now demonstrate that something is wrong with ..read more

Is the Universe Infinite or Finite?
Backreaction
by Sabine Hossenfelder

Is the universe really infinite? Or could it close back on itself like a sphere? If it’s infinite, how can it expand? And is it true that there might be copies of you in it? Today I want to explain how much we know about those questions and what the expansion of space has to do with Hilbert's Hotel. This video comes with a quiz which you can take here: You can now also create ..read more

Self-Censorship is Rising, And It’s a Problem
Backreaction
by Sabine Hossenfelder
1w ago
According to multiple new surveys, many people – including scientists – censor their personal views in fear that their reputations will be damaged or that they will be harassed. Most worryingly, scientists admit to self-censorship even in academic publications. Let’s take a look at this trend and why it’s happening ..read more

Did the Black Hole Information Paradox just Disappear?
Backreaction
by Sabine Hossenfelder
1w ago
Do black holes destroy information? Physicists have been trying to answer that question for decades, because the idea that black holes could irreversibly destroy information is incompatible with the principles of quantum physics. Now, researchers claim that some information actually can escape black holes, so there was never a problem to begin with. Let’s take a look ..read more
