"Time-space compression", she argues, "needs differentiating socially": "how people are placed within 'time-space compression' are complicated and extremely varied". In effect, Massey is critical of the notion of "time-space compression" as it represents capital's attempts to erase the sense of the local and masks the dynamic social ways ...
The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make it possible to travel through time.

In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
Here is an explanation of some of the effects on human health caused by space travel. As a result, trekking beyond the Earth's confines causes many physiological changes that affect an astronaut's ...
The amount of time spent in space is considered a key factor in the health effects, with greater concern over long-duration missions. "The longer the duration in space, the greater the increase in ...
Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity). When unspecified, "time dilation" usually refers to the effect due to velocity.
Space can be an unfriendly place for the human body, with microgravity conditions and other factors tampering with our physiology, from head to toe - head, of course, being a primary concern.
Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. [1] [2] [3] It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the ...
