You can't just introduce a new energy momentum tensor just because the maths looks nice. That requires a new kind of matter and changing the equations of motion as well. And you end up with too many degrees of freedom to satisfy the conditions for the equations.

"A gauge is found which reduces the physics to a set of essentially Newtonian equations." Gravity, Gauge Theories and Geometric Algebra (arXiv:gr-qc/0405033) by Doran, Lasenby and Gull "...the metric tensor can be replaced by the fiducial tensor as a fundamental geometric object on spacetime. In the present formulation of GR, the role of the fiducial tensor is to tie fiducial frames to the spacetime manifold by relating them to coordinate frames." - Spacetime Geometry with Geometric Calculus By David Hestenes "... if one adopts the natural covariant derivative identified in the geometric interpretation of WGTs, properly takes into account the scaling dimension of physical quantities, and recognises that Einstein's original objection requires the presence of massive matter fields to represent atoms, observers and clocks, then WGTs do not predict a second clock effect."

Very interesting and informative discussion!

THERE IS NO SUCH THING AS "DARK MATTER". THE UNIVERSE IS ELECTRIC. "GRAVITY" IS NOT A "FORCE". ELECTRICALLY -CHARGED PLASMAS (WHICH IS ALL PLASMA) PERVADE THE ENTIRE VISIBLE UNIVERSE AND IS RESPONSIBLE FOR EVERYTHING WE: SEE, FEEL, AND ARE. THE SPEED OF LIGHT IS NOT A CONSTANT. "RED SHIFT" IS NOT A PURE FUNCTION OF "DISTANCE". CHALLENGE YOUR ASSUMPTIONS.

Very few ideas I’ll click on if they’re over 1 hour for a talk. 40 mins or less is ideal if possible.

Really interesting paper! But the video is really long and slow. Shorter and faster would really increase your impact and use/knowledge of this work.

This is very interesting. Thank you so much for sharing!

this is so interesting, where can i learn more? coming from an undergraduate physics student in Canada! :)

very interesting, more pics please and better sound and youll be on your way

what a fascinating talk. extremely clearly examined and easy to understand for someone without formal training in cosmology.

How you would 'see' the pass of an hypersphere moving at C through an infinite 3D space? The moment it 'touches' the space is a point ... Each evolving meridian is an 'event horizon' ... At its 'equator' the biggest event horizon ... Remember, a hypersphere doesn't have any inner or outer content in 3d space, What you observe as a point and/or an expansive Sphere is always the same 'object' and for points in 3d space, the surface of the hypersphere goes to infinity, the center of the hypersphere, too ... Finite in 4D space, Tending to Infinite in 3D space. Remember, Poincare conjecture. If that Hypersphere is cutting 3D space at C ... Its finite content 'in' is equal to the energy of the observable universe (event horizon equator ), and that energy was equal at t=0 ( initial point of contact ) ... Therefore, in energy terms, The Volume of Event Horizon of this universe is equal to the Volume of the Universe at t=0 ... Want to know about 'fine-tuning'?? Use CMBR as the 'partial meridian' Event horizon threshold for energy condensation ... Use your star and planet as another 'partial meridian' Event Horizon for a state of fragmentation ... Use star-planet system future predictions in the system as more 'partial meridian' event horizon states ... Use the Visible Universe as 'the event horizon' equator for this universe ... and Pure Dark energy dissipated universe heath death as the last event horizon point. If you are a 3D observer inside that hypersphere , you believe that there is something like an infnitesimal domain tending to minus infinity Outside-inside ... and to believe that there is a tending to infinite space from Inside-Outside ... but that is just a cognitive bias by ignoring the nature of the system ... There is not such a thing as inside and/or outside in Nature ... Nature can ignores anthropomorphic beliefs ...

The brain is an antenna. Memories aren't stored in the brain.

This is the best I've across so far on the LaMoine LaMDA revelations controversy & what it means for all of us.

Why did you, the producers, not record the conversation on a video? It would have been nicer. Great interview anyway. I loved it!

Super excited about Chiara's and Vlatko's work! I wish we could see some of these micro-lensing experiments that the crowd's talking about 😂
