(Phys.org)—Although there are many counterintuitive ideas in quantum theory, the idea that influences can travel backwards in time (from the future to the past) is generally not one of them. However, ...

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 ...

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 ...

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 ...

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 ...

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?

Ever wish you could reach back in time and change the past? Maybe you'd like to take back an unfortunate voice mail message, or rephrase what you just said to your boss. Or perhaps you've even dreamed ...

The article on retrocausality seems to be implying that John Cramer and others are on the verge of sending messages back in time (30 September, p 36). They are not. Retrocausality is a conceptual ...
