World Science Festival | World Science U | The Continuing Quest for the Deep Laws of the Universe

G_{\mu \nu} = R_{\mu \nu} - {1 \over 2}R g_{\mu \nu},

G_{\mu \nu} + g_{\mu \nu} \Lambda = {8 \pi G \over c^4} T_{\mu \nu}.

G_{\mu \nu} + g_{\mu \nu} \Lambda = 8 \pi T_{\mu \nu}\,.

The second day of World Science U focused again on cosmology and physics, without the neuroscientific approach of the previous day. Topics ranged from general relativity to quantum gravity, gravitational waves and string theory.
My favorite lecture "Loop Quantum Gravity: A World Without Time and Space" was delivered byCarlo Rovelli, theoretical physicist at Aix-Marseille University.The lecture introduced Einstein general relativity equations printed on the back of Rovelli's shirt.and focused on four topics:.
1, Gravitational fields combining space time and energy
2. QuantumL Reality is discrete and relational
3. Quantum gravity
4. White holes: Planck star symmetry black and white holes
Feynman graph and spin foam were also introduced with clarity and focus.
