"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.
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 ...
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 ...
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 ...
The measured shape of an object is a hypothetical snapshot of all of the object's points as they exist at a single moment in time. But the visual appearance of an object is affected by the varying lengths of time that light takes to travel from different points on the object to one's eye. Figure 5–5.
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.
[35] Travel to regions of space where extreme gravitational time dilation is taking place, such as near (but not beyond the event horizon of) a black hole, could yield time-shifting results analogous to those of near-lightspeed space travel. Contrarily to velocity time dilation, in which both observers measure the other as aging slower (a ...
