SUMMARY

The discussion centers on the relationship between energy levels and the ability to probe smaller regions of spacetime, specifically questioning whether higher energies, from 1 eV to 10 TeV, correlate with probing smaller spacetime regions. It is established that the Large Hadron Collider (LHC) has only probed up to approximately 4 TeV, suggesting that spacetime may not become discrete until higher energies, potentially around 8 TeV. The conversation also raises the need for astronomical evidence to support the continuity of spacetime beyond the LHC's findings, emphasizing the lack of evidence for discrete spacetime at any scale.

PREREQUISITES
  • Understanding of particle physics and energy scales, particularly in the context of the LHC.
  • Familiarity with concepts of spacetime in theoretical physics.
  • Knowledge of the relationship between energy levels and probing capabilities in high-energy physics.
  • Basic comprehension of the Planck scale and its significance in quantum gravity theories.
NEXT STEPS
  • Research the implications of energy levels on spacetime probing in high-energy physics.
  • Explore the theoretical framework surrounding the Planck scale and its relevance to spacetime discreteness.
  • Investigate the latest findings from the LHC and their implications for our understanding of spacetime.
  • Examine astronomical observations that may provide evidence for the continuity of spacetime at high energy levels.
USEFUL FOR

Physicists, researchers in high-energy particle physics, and anyone interested in the fundamental nature of spacetime and its implications in theoretical frameworks.

Is it true that as you go higher in energy, from 1 eV to GeV to 10 TeV, you can probe smaller spacetime region. Since the LHC has only probed up to the 4 TeV or so, it means they have probed the corresponding tiny region of spacetime.. meaning it is still possible spacetime becomes discrete at say 8 TeV and not near the Planck scale? In other words, the energy probe is directly related to the region of spacetime that can be probed?

Is there astronomical arguments or observation that spacetime is continuous to a certain eV? like 900 TeV? or do we rely solely on the LHC probe so far of 4 Tev to prove that spacetime is continuous up to it (and what is the formula to compute the corresponding tiny spacetime region probed at 4 Tev)?

There is no evidence at any scale that space is discrete.
