The Space-Time Continuum

The term 'Space-Time Continuum' is used to describe the fabric of the universe, which is made up of space and time.

Albert Einstein proposed the theory of general relativity, which revolutionized our understanding of space-time.

According to general relativity, mass causes space-time to curve.

Gravitational lensing is the phenomenon observed when light passes through a gravitational field, causing its path to bend.

Time dilation is the term used to describe the slowing down of time in the vicinity of a massive object.

Length contraction is the term used to describe the shortening of objects in the direction of motion as they approach the speed of light.

Gravitational waves are the ripples in space-time caused by the acceleration of massive objects.

The first direct detection of gravitational waves was made in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO).

The term 'Event Horizon' is used to describe the hypothetical boundary of space-time, beyond which nothing, not even light, can escape.

The term 'Wormhole' is used to describe a hypothetical tunnel connecting two different regions of space-time.

The term 'Singularity' is used to describe the point of infinite density and gravity at the center of a black hole.

The term 'Gravitational Time Dilation' is used to describe the phenomenon where time appears to pass more slowly for an observer in a stronger gravitational field compared to an observer in a weaker gravitational field.

The term 'Length Contraction' is used to describe the phenomenon where objects appear to be shorter in the direction of motion as they approach the speed of light.

The term 'Mass Dilation' is used to describe the phenomenon where the mass of an object appears to increase as it approaches the speed of light.

The term 'Gravitational Equivalence Principle' is used to describe the phenomenon where two objects with different masses fall at the same rate in a gravitational field.
