What causes frame dragging?
Basically, frame dragging is an effect that occurs when one object is moving near another, which makes both objects change their motion because of the other’s motion. Frame dragging does not occur if an object is neither spinning nor moving.
What is frame dragging of space-time around rotating bodies?
Lense-Thirring effect
That prediction is a phenomenon known as frame dragging, or the Lense-Thirring effect. It states that space-time will churn around a massive, rotating body. For example, imagine Earth were submerged in honey. As the planet rotated, the honey around it would swirl — and the same holds true with space-time.
What happens to space when a massive object is places in it?
“At its most basic, general relativity is a way to describe gravity by attributing it to the curvature of space-time that occurs in the presence of massive bodies. Massive objects cause space-time to stretch.
Which of the following is implied by frame dragging in general relativity?
Geodesics are the shortest distance between two points in curved space time. Which of the following is implied by frame dragging in general relativity? There are no static observers inside a spinning black hole’s ergosphere.
What is drag lens?
A drag lens provides a view into a different part of the list that can serve as a shortcut target.
What does it mean to warp spacetime?
A time warp can be thought of as anything that disrupts the flow of time by making it go faster or slower. This effect is known as gravitational time dilation, and it results from distortions in space-time.
What is space in space time?
In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur.
Why do massive objects curve spacetime?
Originally Answered: Why do massive objects distort space-time? Since matter carries energy (via Einstein’s famous relation that energy is mass times the speed of light squared), such objects will have a gravitational field and so they will distort space-time. …
What is Einstein’s frame dragging?
Frame-dragging is an effect on spacetime, predicted by Albert Einstein’s general theory of relativity, that is due to non-static stationary distributions of mass–energy. A stationary field is one that is in a steady state, but the masses causing that field may be non-static — rotating, for instance.
