Gravity Space Time

A spacetime diagram is typically drawn with only a single space and a single time coordinate.

Gravity space time. In 2004 nasa launched the gravity probe b gp b. Speed distance time. The spin of a heavy object such as earth should twist and distort the space time around it. Gravity is an effect of the warping of space and time in the presence of mass my first encounter with warped space and time was on a merry go round in 8th grade.

2 1 presents a spacetime diagram illustrating the world lines i e. In addition c illustrates the world line of a slower than light. A rational explanation of many enigmas of physics is also given in that webpage. In thinking about the example of the cylindrical ride we see that accelerated motion can warp space and time.

Gravity spacetime curvature gravity would not be an attractive force between masses but an external pressure force produced by the spacetime curvature. Paths in spacetime of two photons a and b originating from the same event and going in opposite directions. It is here that einstein connected the dots to suggest that gravity is the warping of space. Gravity is the curvature of spacetime.

Gravity is no longer thought of as a force as in the newtonian system but as a cause of a warping of space time an effect described explicitly by a set of equations formulated by einstein. Frame dragging of space time around rotating bodies. The result is a curved space time as opposed to the flat minkowski space time where trajectories of particles are straight lines in an. Faster than light neutrinos time dilatation mass of relativistic particles e mc black holes.

In other words time runs slower wherever gravity is strongest and this is because gravity curves space time. Light in this case speed is always constant and travels at a speed of 180 000 miles per second. The force of gravity is stronger towards the surface of earth where the curvature is more intense than it is on its fringes. Think of it this way time follows a simple equation.

Gravitational time dilation is a form of time dilation an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass the lower the gravitational potential the closer the clock is to the source of gravitation the slower time passes speeding up as the gravitational potential increases the clock getting away from the.
