Are space and time emergent or fundamental?

Space and time are so fundamental to our understanding of the universe that they are woven into nearly every equation in physics.

Is space time an emergent property?

It is widely believed that spacetime is emergent. It is not clear, however, where the process of its emergence takes place. The majority of physicists tend to suppose that spacetime is created on the Planck scale, at distances close to one trillionth of a trillionth of a metre (~10-35 m).

What does it mean that space time is not fundamental?

Other theories, such as loop quantum gravity, propose that spacetime is not fundamental. Rather, events and the connections between events is. Space and time is ultimately the product of interconnected things happening and causing one another. Causal set theory is similar in this way.

Does space not exist?

Space (or spacetime) does not exist fundamentally: it emerges somehow from a more fundamental non-spatio-temporal structure. In quantum gravity, research programs such as loop quantum gravity state that the relativist spacetime is not fundamentally real and emerges somehow from a non-spatio-temporal ontology2.

Why is spacetime not fundamental?

What does it mean that time is emergent?

Time can be viewed as an emergent property : whenever any change occurs anywhere in the universe – in other words whenever the state space of the universe undergoes any change – then Time itself happens and ‘notches up’ one tick (at least in the ‘neighbourhood’ of the change, which is a separate discussion.)

What are some properties of space?

The physical properties of space are rich in paradoxes. Space seems empty but contains valuable resources of energy and matter and dangerous fluxes of radiation. Space seems featureless but has hills and valleys of gravitation. Space is harsh and lifeless but offers opportunities for life beyond those of Earth.

What is space-time and reality?

The true origins of the fabric of reality. “Space-time” is simply the physical universe inside which we and everything else exists. And yet, even after millennia living in it, we still don’t know what space-time actually is. Physicists have strived to work it out for more than a century.

Are space & time fundamental properties of the universe?

There is popular theoretical “belief” among some leading physicists that space & time may not be fundamental property’s of the universe & the governing laws of nature. Theoretical physicists like Nima Arkani-Hamed & Sean Carrol seriously consider that space and maybe time are rather emergent properties, coming from something more fundamental.

Are space and time emergent properties?

Theoretical physicists like Nima Arkani-Hamed & Sean Carrol seriously consider that space and maybe time are rather emergent properties, coming from something more fundamental. This line of thought is driven by gravity and quantum mechanics at the most extreme small limits (Planck scales).

What is the relationship between space and time?

Space is defined by three dimensions…Time adds the fourth dimension which we see as spacetime. Space and time are also interchangable, and all while being abstract concepts, are still real. Whether they are fundamental maybe revealed by a future validated QGT. You may have seen this interview with Professor Carroll…..

Is time tangible or intangible?

Answer Wiki. TIME is not something tangible. Scientists propose that clocks measure only the numerical order of material change in space, where space is a fundamental entity; time itself is not a fundamental physical entity.
