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 ...
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 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 ...
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 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 ...
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?
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 ...
IF YOU were to break your arm tomorrow afternoon, would you suddenly find it hanging useless in a sling this morning? Of course not – the question makes no sense. Cause always precedes effect. But ...
