Time dilation by the Lorentz factor was predicted by several authors at the turn of the 20th century. [3] [4] Joseph Larmor (1897) wrote that, at least for those orbiting a nucleus, individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio: . [5]
For example, considered over the total time-span of Earth (4.6 billion years), a clock set in a geostationary position at an altitude of 9,000 meters above sea level, such as perhaps at the top of Mount Everest (prominence 8,848 m), would be about 39 hours ahead of a clock set at sea level.
The speed at which cancer advances, the prognosis, the degree of pain, and every other feature of the disease are not functions of the radiation dose to which the person is exposed. This contrasts with the deterministic effects of acute radiation syndrome which increase in severity with dose above a threshold.
If you travelled a year at 95% the speed of light; you'd age one year, and people on Earth would age 3.2 years! But if you were going 50% the speed of light it would only be 1.15 years. The effect ...
At high altitude, in the short term, the lack of oxygen is sensed by the carotid bodies, which causes an increase in the breathing depth and rate . However, hyperpnea also causes the adverse effect of respiratory alkalosis , inhibiting the respiratory center from enhancing the respiratory rate as much as would be required.
The steam may bloat the body up to twice its normal size and slow down circulation, but tissues are elastic and porous enough to prevent rupture. [35] Technically, ebullism is considered to begin at an elevation of around 19 kilometres (12 mi; 62,000 ft) or pressures less than 6.3 kPa (47 mm Hg), [36] known as the Armstrong limit. [20]
Increasingly, she says, a growing body of research has indicated that inflammation, once thought to be just a consequence of disease, might actually be an independent cause of chronic diseases ...
The report emphasized that while there was major progress in cancer treatment over the 30-year study period, with roughly 4.5 million cancer deaths avoided nationwide from 1991 to 2022, there are ...
