Within each orbit of the Parker Solar Probe around the Sun, the portion within 0.25 AU is the Science Phase, in which the probe is actively and autonomously making observations. Communication with the probe is largely cut off in that phase. [57]: 4 Science phases run for a few days both before and after each perihelion. They lasted 11.6 days ...
A NASA probe ventured closer to the sun than any spacecraft in history on Christmas Eve — and it whirled by at astounding speeds that also made it the fastest thing ever made by humans. Just ...

PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.
[7] [8] The possibility of existence of faster-than-light particles was also proposed by Lev Yakovlevich Shtrum in 1923. [9] The term tachyon was coined by Gerald Feinberg in a 1967 paper titled "Possibility of faster-than-light particles". [3] He had been inspired by the science-fiction story "Beep" by James Blish.

Gravitational waves are an important prediction from Einstein's general theory of relativity and result from the bulk motion of matter, fluctuations during the early universe and the dynamics of space-time itself. Pulsars are rapidly rotating, highly magnetized neutron stars formed during the supernova explosions of massive stars. They act as ...
The universe is expanding faster than previously believed, a surprising discovery that could test part of Albert Einstein's theory of relativity. Astronomers say universe expanding faster than ...
In physics, a tachyonic field, or simply tachyon, is a quantum field with an imaginary mass. [1] Although tachyonic particles (particles that move faster than light) are a purely hypothetical concept that violate a number of essential physical principles, at least one field with imaginary mass, the Higgs field, is believed to exist.
