Description
The ( H_0 ) and ( S_8 ) tensions pose significant challenges to the standard ( \Lambda )CDM model, arising from discrepancies in local versus early-Universe ( H_0 ) measurements and inconsistencies between CMB and weak lensing data. We explore two ( f(T) ) gravity models as alternatives by analyzing cosmic chronometers, BAO, gamma-ray bursts, and Pantheon+SH0ES datasets, with gravitational wave data used for validation. Our results show that both teleparallel models offer promising potential in jointly alleviating these tensions.
