In Yang-Mills theories there's a phase-shift 'operator' defined on particles from the Standard Model, that for instance, transform protons into neutrons and back.

But apart from that, we have fiber bundles, where a fiber can be a symmetry group, like SU(2). In an article by Bernstein and Phillips, the idea of a bundle of directions is used, such that each fibre is the interval [0,2π), but this only (obviously) makes sense if there is a...

So, what is time?

Could it be an illusion?

So if time is a continuous 'space' which looks like a continuous symmetry of nature, what does that mean? Time is always mathematically represented as an element of the real numbers, i.e. having just one dimension.

Simultaneous events have the same real number assigned to them, in a larger space (mathematically speaking).]]>

Personally, I've always thought (purely for philosophical reasons) that the answer is "yes": his conclusion about her current age IS "meaningful", "real", and "true". I base that on...

The experiment utilizes a Femto camera. A Femto camera takes a trillion frames per second and is capable of capturing light in slow motion as it leaves its source. The link below is a video of just that. By pausing the video where light has expanded into s sphere, one can then measure for space 'moving past' just as they did in the M&M experiment....

The theory of general relativity predicts the existence of closed time-like curves (CTCs), which theoretically would allow an observer to travel back in time and interact with their past self. This raises the question of whether this could create a grandfather paradox, in which the observer interacts in such a way to prevent their own time travel. Previous research has proposed a framework for deterministic, reversible, dynamics compatible with non-trivial time...

An international collaboration of scientists has recorded the most accurate confirmation to date for one of the cornerstones of Einstein's theory of general relativity, 'the universality of free fall."

The new research shows that the theory holds for strongly self-gravitating objects such as neutron stars. Using a radio telescope, scientists can very accurately observe the signal produced by...
