Dear Prof. Dr. José M. M. Senovilla:

Of course, you have had substantial influence in how we all think about a singularity, be it an initial singularity, gravitational singularity, spacetime singularity or “a location in spacetime where the curvature becomes infinite.” Yet, who talks about infinity? Who talks about Planck’s base units? Who talks about absolute space and time?

It’s all too disconcerting.

Not arguing the place for the work of Dyson, Witten, Weinberg or Wilson, bottomline, renormalization doesn’t deny infinity. Might we allow infinity to be defined strictly as continuity, symmetry and harmony, all being defined by the sphere and circle?

Would you try to define infinity?

Might you entertain my definition? Thank you.

Dear Prof. Dr. José M. M. Senovilla:

If the Planck base units are real, might it be the transformation point that is defined as a singularity?

Is Planck Time the first unit of time?

Can we be thinking beyond global causality and about causality throughout the universe?

There are 202 base-2 notations from the Planck units to the current time:  https://81018.com/chart/ Interpretation: https://81018.com/empower/
Thank you.

The associated energy-momentum tensor Tμv generates a gravitational field which, in principle, should be determined by solving Einstein’s equations for the metric ημV9

Rμv-½Rημv = 8πTμv.

The smaller the uncertainties Δxμ in the measurement of coordinates, the stronger will be the gravitational field generated by the measurement. When this field becomes so strong as to prevent light or other signals from leaving the region in question, an operational meaning can no longer be attached to the localization.
