Is spacetime a quantum field?

Sure, everything is quantum, but not everything is discrete. In Einstein’s relativity, space and time are still treated as two linked parts of a continuous fabric. In quantum field theory, spacetime is the continuous stage on which the dance of the quanta takes place.

Is space/time gravitational field?

as the discovery that spacetime geometry is nothing but a manifestation of a particular physical field, the gravitational field. Arguably, the geometric and the field interpretation can be cashed out in different ways, making them families of positions rather than single positions.

Is spacetime made of anything?

Spacetime isn’t “made of” any material or substance, i.e. it is an immaterial, insubstantial thing.

Is gravity a field or a particle?

Gravity is a force. For all other forces that we are aware of (electromagnetic force, weak decay force, strong nuclear force) we have identified particles that transmit the forces at a quantum level. In quantum theory, each particle acts both as a particle AND a wave.

What exactly is spacetime?

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.

Can the fabric of space be ripped?

In general relativity, spacetime can be curved but can never be torn, because in GR, topology of spacetime can’t change, only geometry can change.

Is gravity just electromagnetism?

Gravity is definitely not part of the electromagnetic spectrum. Properties of the gravitational force are very different to the electromagnetic force, (apart from the 1/r^2 law).

Is graviton a boson?

The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism’s spin-1 photon, the source of which is the four-current, a first-order tensor). …

Why is space-time not a field?

Space-time is not a field, since it bears on no charge. Charge and field are heraldic terms for the intrinsic and extrinsic parts of a force by position. Space-time yields no force, and can not be a field. Nor is air a field.

Is spacetime a real physical thing?

Spacetime is a mathematical and geometric construct to describe how objects and light move during the gravitational process. It represents a field, but spacetime is not the gravitational field itself like a map is not the landscape. The fundamental gravitational field is a real physical entity however.

What is spacetime energy?

Spacetime is an energy field consisting of E0 energy and it is the interaction of the E1 and/or E2 energy fields of particles interacting with the E0 energy of spacetime that creates the various energy fields associated with particles.

What is the difference between flat spacetime and curved spacetime?

The flat spacetime paradigm turns out to be especially convenient when performing approximate calculations in weak fields. Hence, flat spacetime techniques will be used when solving gravitational wave problems, while curved spacetime techniques will be used in the analysis of black holes.
