Why does Hot Dark Matter “suppress” structure formation and predict for example less satellite galaxies being formed?

Why does the power spectrum change at matter-radiation domination equivalence and why is there a difference between Hot, warm, and cold dark matter?

How does inflation predict an initial power spectrum to be P(k) ~ k^n?

Is there an intuitive interpretation of the Nambu-Goto or Polyakov action/lagrangian in terms of L= T-V or so?

If D-branes are interpreted as not fundamental but rather “made up of open strings”, and M theory doesn’t have fundamental strings only D-branes, do D-branes get promoted to fundamental objects in M theory?

How can the maximal number of degrees of freedom in the SM be 106.75? What’s 0.75 of a dof?

What is the mathematical definition of a gauge symmetry or gauge transformation?

What research and improvements can be done on superdeterminism?

How is quantisation in LQG incompatible with standard quantisation?

Why do quantum gravity effects set in at L~ sqrt(hG/c^3) or at E ~ sqrt(hc^5/G)?

If the Einstein field equations say essentially „Geometry=stress-energy tensor“, does that mean we need to obtain a notion of “quantum geometry” if we want to quantise GR?

What is the lagrangian of a massless spin 2 particle?

Why is it that we can treat q and qdot as two different variables in the lagrangian?

What animal is unfairly demonized?

What theories would be confirmed/disproven with more decimal places?

How do we determine if the sample size of a population is significant enough to extrapolate to the entire population?

What’s the problem with H=sqrt(p^2 + m^2) as a Hamiltonian?

What are issues with interpreting the Dirac equation as a relativistic wave equation?

Why can a particle with enough energy just randomly convert into two particles?

Why is the position eigenbasis not really a proper basis?
