Is the temperature of the universe rising?

Are there theories about the end of the universe where time ends?

Why is dark energy dominant between galaxies but not inside galaxies?

Why is CMB an evidence of hotter and denser early Universe?

If spacetime itself is expanding, how could we ever tell?

How can we distinguish between the metric expansion of space and the speed of light slowing over time?

Is the "cosmological constant tension" the prime reason that we believe the expansion of the universe is accelerating?

Is the energy density of vacuum uniform in the whole universe?

Does an atom or proton (cosmic ray) get stretched when traveling through expanding space?

How do we know that dark matter energy density scales as $\rho\propto a^{-3}$?
