Spacetime proven or is the Graviton still alive?

In summary, the concept of spacetime (SR) has been experimentally proven, but the existence of gravitons is still below the threshold of detection. However, if quantum mechanics applies to gravity, it is likely that gravitons exist as a result of the quantization of the continuous field.

Has the interlinking of space and time been proven? If so, how?

Is there any hope left for the graviton?

Why would you think they are mutually exclusive?

Spacetime (SR) has been well verified experimentally, but even classical gravity waves are below the threshold of detection, let alone gravitons.

So the graviton is thought to warp space and time just like the warping of spacetime?

Any time you quantize a continuous field, particles pop out of the math. It applies to pseudo-particles like electron density waves. Certainly applies to gravity too. If QM works with gravity at all, you "get" gravitons.
 

FAQ: Spacetime proven or is the Graviton still alive?

Is spacetime proven to exist?

Yes, spacetime has been proven to exist through various experiments and observations, such as the bending of light by massive objects and the effects of time dilation.

What is spacetime?

Spacetime is a mathematical model that combines the three dimensions of space with the dimension of time. It is the fabric of the universe in which all matter and energy exist.

What is the role of the graviton in spacetime?

The graviton is a theoretical particle that is thought to be the carrier of the force of gravity in the framework of quantum mechanics. It is believed to play a key role in the interaction between matter and spacetime.

Has the existence of the graviton been proven?

No, the existence of the graviton has not been proven. It is still a purely theoretical concept and has not been observed or detected experimentally.

Is the concept of spacetime still relevant in modern physics?

Yes, the concept of spacetime is still very relevant in modern physics. It is a fundamental part of many theories, including general relativity and quantum mechanics, and is crucial in our understanding of the universe.
