"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 ...
"It is of interest that even in the objective world of science man's mind is not more malleable than in the habit-bound world of everyday life. Max Planck maintained that a new scientific truth does not triumph by convincing its opponents, but because its opponents eventually die, and a new generation grows up that is familiar with it.
This is an accepted version of this page This is the latest accepted revision, reviewed on 18 December 2024. Problem of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy between ...
The laws of physics are the same for all observers in any inertial frame of reference relative to one another (principle of relativity). The speed of light in vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source. The resultant theory copes with experiment better than classical mechanics.
The field equations of general relativity are not parameterized by time but formulated in terms of spacetime. Many of the issues related to the problem of time exist within general relativity. At the cosmic scale, general relativity shows a closed universe with no external time. These two very different roles of time are incompatible. [4]
RM: Tell me how you first got into space exploration. AB: Growing up, it was all over the news: the Gemini program, the Apollo program, the Mercury program. Every time Apollo would launch, we would watch it on TV, and when the moon landings happened—oh my goodness, that was amazing. That definitely inspired me.
One set of tests focuses on effects predicted by general relativity for the behavior of gyroscopes travelling through space. One of these effects, geodetic precession, has been tested with the Lunar Laser Ranging Experiment (high-precision measurements of the orbit of the Moon). Another, which is related to rotating masses, is called frame-dragging
“Looks like the people want to abolish the annoying time changes!” he wrote in response to an X user who made poll that showed wide support for abolishing Daylight Saving Time.
