Summary<br />

• Certa<strong>in</strong> static s<strong>in</strong>gularities <strong>in</strong> GR are resolved <strong>in</strong><br />

perturbative str<strong>in</strong>g theory, , while others are<br />

resolved by <strong>in</strong>vok<strong>in</strong>g non-perturbative degrees<br />

of freedom.<br />

• Understand<strong>in</strong>g the cosmological s<strong>in</strong>gularities is<br />

a big challenge for str<strong>in</strong>g theory.<br />

• Non-perturbative framework like the AdS/CFT<br />

correspondence gives promis<strong>in</strong>g avenue for<br />

attack<strong>in</strong>g the problem.
