An eclipsing binary is two close stars that appear to be a single star varying in brightness. The variation in brightness is due to the stars periodically obscuring or enhancing one another. The ecliptic is the plane of our solar system . In the course of a year, the sun traces a path in the sky along the ecliptic. This huge cloud of dust and gas is expanding outwards at very high speeds.
Dust obscures our view of the star within.
He revolutionized our conception of the universe with his Theories of Special and General Relativity. Special relativity supplanted Newtonian mechanics, yielding different results for very fast-moving objects. The theory also states that time and distance measurements are not absolute but are instead relative to the observer's frame of reference. Space and time are viewed as aspects of a single phenomenon, called space-time. Energy and momentum are similarly linked.
