What is the theory of relativity How does special relativity differ from general relativity?
Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.
What is Albert Einstein special theory of relativity?
The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels.
In what way do observations of binary star systems support the special theory of relativity?
In what way do observations of binary star systems support the special theory of relativity? The fact that the stars appear distinct supports the idea that the speed of light is unaffected by the motion of the stars. At the same instant, Ben bursts out of the starting blocks at 99% of the speed of light (0.99c).
Why do the predicted consequences of the special theory of relativity seem so strange to most of us?
Why do the predicted consequences of the special theory of relativity seem so strange to most of us? Because they are obvious only at speeds that we never experience in our daily lives. You throw a ball in his direction at a speed of 75 km/hr.
What do we mean by a hot Jupiter?
Hot Jupiters are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (P < 10 days). The close proximity to their stars and high surface-atmosphere temperatures resulted in the moniker “hot Jupiters”.
How many star systems are binary?
Perhaps up to 85% of stars are in binary systems with some in triple or even higher-multiple systems.
Which is hotter Rigel or Spica?
In contrast, Rigel, the bright, bluish-white star at the southwest corner of Orion, is smaller and much hotter than Betelgeuse. Spica is also a bluish star with a surface temperature of around 20,000 degrees Kelvin, over three times as hot as the sun.
Which is hotter capella or sun?
Capella Ab is hotter but dimmer, being 72.7 ± 3.6 times brighter than the sun, and having a surface temperature of around 5.730 ± 60 K. They are very dim, Capella H has 0.05 the sun’s luminosity and around 0.54 solar radii. To be more accurate, both stars have a combined visual luminosity around 1% that of our sun.
Which star has the greatest size?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
