The mathematics of curved spaces - Open Day 2021

Mathematics Open Day 2021 at the University of Cambridge - Dr Maciej Dunajski talks about the mathematics of curved spaces, beginning with bugs and ending with black holes. On the way, non-euclidean geometries are introduced, and you'll also learn some interesting facts relevant to flight paths and to map making.

ELECTROMAGNETISM/energy is gravity ON BALANCE. Here's why.
Notice that gravity cannot be shielded or blocked, as it is fundamental.
INSTANTANEITY (or the present) is fundamental to the FULL and proper UNDERSTANDING of physics/physical experience, as ELECTROMAGNETISM/energy is gravity ON BALANCE. Carefully consider what is THE EARTH/ground ON BALANCE, as ELECTROMAGNETISM/energy is gravity ON BALANCE. Accordingly, ON BALANCE, the ultimate mathematical unification AND UNDERSTANDING of physics/physical experience combines, BALANCES, AND INCLUDES opposites; AS E=MC2 IS F=ma ON BALANCE; as the rotation of WHAT IS THE MOON matches it's revolution; as ELECTROMAGNETISM/energy is gravity ON BALANCE. Indeed, TIME dilation ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity. Great. In fact, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/energy is gravity ON BALANCE. The stars AND PLANETS are POINTS in the night sky.
The SUPERGIANT STARS and the cosmological redshift prove that ELECTROMAGNETISM/energy is gravity ON BALANCE.
TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity ON BALANCE. Gravity is ELECTROMAGNETISM/energy ON BALANCE, as this NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS ELECTROMAGNETISM/energy is gravity ON BALANCE. TIME dilation ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity ON BALANCE. Excellent. It ALL CLEARLY makes perfect sense. Carefully consider what is THE EARTH/ground ON BALANCE. Great.
The tides are ELECTROMAGNETIC/gravitational in a balanced MIDDLE DISTANCE fashion/relation, as ELECTROMAGNETISM/energy is gravity ON BALANCE. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, as ELECTROMAGNETISM/energy is gravity ON BALANCE. This is consistent with F=ma AND E=mc2. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution. The stars AND PLANETS are POINTS in the night sky. Inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL force/ENERGY, as this balances gravity AND inertia; as ELECTROMAGNETISM/energy is gravity ON BALANCE. This is consistent with F=ma AND E=mc2 AS WELL. Gravity is ELECTROMAGNETISM/energy on balance, as gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites ON BALANCE. Carefully consider, in direct comparison, the fully illuminated (and setting) Moon AND what is the ORANGE (and setting) Sun. They are both the same size as the eye. Now, the sky is blue; and THE EARTH is ALSO BLUE. ELECTROMAGNETISM/energy is gravity ON BALANCE.

UNDERSTANDING TIME, THE COSMOLOGICAL REDSHIFT, GRAVITY, AND WHY THE ROTATION OF THE MOON MATCHES IT'S REVOLUTION:
Einstein never nearly understood gravity, physics/physical experience, AND TIME. So, carefully consider that the stars AND PLANETS are POINTS in the night sky. Carefully consider what is THE SUN. Finally, very carefully consider what is THE EARTH/ground ON BALANCE. This is top down simplicity at it's finest. ELECTROMAGNETISM/energy is gravity. Consider what is the man (AND THE EYE) who actually is in what is outer “space”. NOW, think about TIME. BALANCE AND completeness go hand in hand. Excellent. Notice the blue sky, as the Earth is ALSO BLUE. Think about TIME. Great.
Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, as ELECTROMAGNETISM/energy is gravity ON BALANCE !!! (This explains F=ma AND E=mc2 in balance, as BALANCED inertia/INERTIAL RESISTANCE is fundamental). Accordingly, ON BALANCE, inertia/INERTIAL RESISTANCE is proportional to (or BALANCED with/as) GRAVITATIONAL/force ENERGY; as this balances gravity AND inertia; as ELECTROMAGNETISM/energy is gravity ON BALANCE. The stars AND PLANETS are POINTS in the night sky, AND carefully consider what is the speed of light (c) ON BALANCE !!! Indeed, A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course); AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c) ON BALANCE !!! ELECTROMAGNETISM/energy is then CLEARLY proven to be gravity ON BALANCE.
So, I have also CLEARLY explained the supergiant stars and the black hole(s) as well. It is, moreover, clearly proven that what is THE EARTH/ground is ALSO a BALANCED MIDDLE DISTANCE manifestation, as this NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/energy is then CLEARLY proven to be gravity ON BALANCE. Finally, the tides are clearly reflective of what is necessarily and CLEARLY ELECTROMAGNETIC/gravitational balance (or equilibrium) as well.
TIME is NECESSARILY possible/potential AND actual IN BALANCE, as ELECTROMAGNETISM/energy is gravity ON BALANCE. Gravity is ELECTROMAGNETISM/energy, as E=MC2 AND F=ma (ON BALANCE) ultimately represent what is possible/potential AND actual IN BALANCE; as ELECTROMAGNETISM/energy is then CLEARLY proven to be gravity (ON BALANCE) !!! Indeed, TIME dilation ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity ON BALANCE !!! Indeed, the stars AND PLANETS are POINTS in the night sky. Carefully consider what is THE EARTH/ground ON BALANCE. Gravity is ELECTROMAGNETISM/energy ON BALANCE. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites ON BALANCE, as ELECTROMAGNETISM/energy is gravity ON BALANCE !!! (Energy has/involves GRAVITY, AND ENERGY has/involves what is clearly BALANCED inertia/INERTIAL RESISTANCE.) It ALL CLEARLY makes perfect sense, AS BALANCE AND completeness go hand in hand. In fact, what is clearly the ultimate mathematical unification and UNDERSTANDING of physics/physical experience combines, BALANCES, AND INCLUDES opposites. Importantly, notice that the integrated extensiveness of thought (and description) is improved in the truly superior mind.
SO, the following ALSO explains why the rotation of WHAT IS THE MOON matches it's revolution. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, as ELECTROMAGNETISM/energy is gravity ON BALANCE. Accordingly, ON BALANCE, THE PLANETS (INCLUDING WHAT IS THE EARTH and the Moon) move away very, very, very, very slightly in relation to what is THE SUN !!! The stars AND PLANETS are POINTS in the night sky, AND consider what is the speed of light (c) ON BALANCE. Excellent !!! Consider what is the blue sky as well. The Earth is ALSO BLUE. Great !!! Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, as gravity is CLEARLY ELECTROMAGNETISM/energy ON BALANCE !!! It is absolutely correct, and it is definitively proven. SO, I have also CLEARLY explained the cosmological redshift AND the black hole(s) ON BALANCE !!! Gravity is ELECTROMAGNETISM/energy ON BALANCE. Moreover, on balance, I have explained what are the supergiant stars !!! Great. It ALL CLEARLY makes perfect sense, as BALANCE AND completeness go hand in hand. Look in a mirror, and then see the black “space” of WHAT IS THE EYE !!! ELECTROMAGNETISM/energy is gravity ON BALANCE !!!! What is THE EARTH/ground is NECESSARILY a MIDDLE DISTANCE form, as ELECTROMAGNETISM/energy is gravity ON BALANCE. Indeed, this is then consistent with F=ma AND E=mc2 IN BALANCE !!!! GREAT. Gravity is ELECTROMAGNETISM/energy ON BALANCE. WONDERFUL !!!!
The fourth dimension is the BALANCED SPACE of your experience. BALANCED inertia/INERTIAL RESISTANCE is fundamental, as ELECTROMAGNETISM/energy is gravity (ON BALANCE). Carefully consider what is THE SUN. Consider the speed of light (c) ON BALANCE !!! The stars AND PLANETS are POINTS in the night sky. NOW, ON BALANCE, think carefully about what is THE EARTH/ground !!!! SO, carefully think about TIME (ON BALANCE) as well !!!! Gravity is ELECTROMAGNETISM/energy ON BALANCE !!!! BALANCE and completeness go hand in hand. It all CLEARLY makes perfect sense. Great !!!!
