Existence of Space: Does it Exist at Planck Level?

In summary, there has been research on the idea that time may not exist at the fundamental level of reality, and it is speculated that space may also not exist at that level. However, since space and time are intertwined in the concept of space-time, it is likely that space is also emergent at the fundamental level.

Hi. I think there has been research about the idea that time may not exist on the very fundamental level of reality. Does anyone know if space exists at that same level? I have read somewhere that at the Planck level, which is the smallest level physicists have gone to, time and distance drop out of the mathematical equations.

Read where? We can't explain what you've read if we don't know what it is.

Its possible - but its highly speculative.

Since we know space and time don't exist independently and we really have space-time if time is emergent its a pretty safe bet space is as well.

Thanks

Related to Existence of Space: Does it Exist at Planck Level?

1. What is the Planck level and why is it important?

The Planck level is the smallest unit of measurement in the universe, named after physicist Max Planck. It is approximately 1.6 x 10^-35 meters and is significant because it is believed to be the scale at which the fabric of space-time is formed.

2. How does the existence of space at the Planck level affect our understanding of the universe?

The existence of space at the Planck level challenges our current understanding of the universe as it suggests that space is not continuous, but rather made up of discrete units. This could also have implications for theories such as string theory and the search for a theory of quantum gravity.

3. Is it possible that space does not exist at the Planck level?

While there is no definitive answer, many scientists believe that space does indeed exist at the Planck level. This is based on various theories and experiments, including the observation of fluctuations in the fabric of space-time at the Planck scale.

4. How do we measure or observe space at the Planck level?

At this point in time, we do not have the technology or means to directly measure or observe space at the Planck level. However, scientists have used mathematical models and experiments, such as the Large Hadron Collider, to study the behavior of particles at this scale and gain insights into the nature of space.

5. What are the implications of the existence of space at the Planck level for the origin of the universe?

The existence of space at the Planck level has significant implications for our understanding of the origin of the universe. It suggests that the universe may have originated from a singularity at the Planck scale and that the fabric of space was created at the same time as the Big Bang.
