Nov 18, 2025 by The Conversation

In his new book ‘A Brief History of the Philosophy of Time,’ Wake Forest University’s Professor Adrian Bardon proposes that our sense of the passage of time is an example of psychological projection — a type of cognitive error that involves misconceiving the nature of your own experience. Time is an example of psychological projection. Image credit: Gemini AI. ‘Time flies,’ ‘time waits for no one,’ ‘as time goes on:’ the way...

The world’s first neutrino observation in a hydrogen bubble chamber. It was found November 13, 1970, on this photograph from the Zero Gradient Synchrotron’s 12-foot bubble chamber. The invisible neutrino strikes a proton where three particle tracks originate (lower right). The neutrino turns into a mu-meson, the long center track (extending up and left). The short track is the proton. The third track (extending down and left) is a pi-meson created by the collision. Image credit: Argonne National Laboratory.

Black holes are the sources of the strongest gravitational fields that can be found today in the Universe and are ideal laboratories for testing Einstein’s theory of general relativity in the strong field regime. In his article, Professor Bambi shows that the possibility of an interstellar mission to send a small spacecraft to the nearest black hole, although very speculative and extremely challenging, is not completely unrealistic.
