- TL;DR Summary
- The vacuum energy density of the vacuum, as calculated in standard QFT, shows a discrepancy of about $10^{120}$ with what we see. Has the value been calculated in string theory, which doesn't assume point-like particles?

The calculation of the vacuum energy density gives us a discrepancy with reality. There should be a mass equivalent of about $10^{96}$ kilograms. I'm wondering if the assumed point-like "structure" of particles could be the cause of this wrong value.

Since string theory doesn't assume a point-like structure, I asked myself if a calculation of the energy density with strings has been done.
