Since you first started learning about the world, you’ve known that cause leads to effect. Everything that’s ever happened to or near you has reiterated this point, making it seem like a fundamental ...

Science is stranger than sci-fi is proven again as an idea to explain some core concepts of quantum mechanics, is leading to a theory of the future affecting the past writes Satyen K. Bordoloi. A ...

In grammar, we learn about the past, present, and future tenses from an early age. This shapes our understanding of time as a one-way arrow. Eggs break, but don’t un-break; we grow older, but never ...

In the quantum world, our intuitive grasp of past, present and future may not apply. Richard Fisher explores the discombobulating concepts of "negative time" and "retrocausality". Tony Soprano is ...

Does time have a direction? You’d think so. When you pour cream into coffee, it swirls around and paints your cup o’ joe a lighter brown—the cream doesn’t tend to funnel itself out of your coffee and ...

Retrocausality is primarily a thought experiment in philosophy of science based on elements of physics, addressing the question: Can the future affect the present, and can the present affect the past?

Huw Price has received funding from the Australian Research Council and the Leverhulme Trust. Ken Wharton does not work for, consult, own shares in or receive funding from any company or organization ...

If his experiment with splitting photons actually works, says University of Washington physicist John Cramer, the next step will be to test for quantum "retrocausality." That's science talk for saying ...

The original paper by Kim et al. on the Delayed Choice Quantum Eraser suggests the concept of retrocausality, which stems from classical interpretations. In quantum mechanics, particles exhibit ...

In 2022, the physics Nobel prize was awarded for experimental work showing that the quantum world must break some of our fundamental intuitions about how the universe works. Many look at those ...
