It’s not all that broad of a brush. White Christian Nationalists (White+Christian+Nationalist) is the intersection of three groups. It does not imply that all whites, or all Christians, are nationalists.

Perhaps somewhat ironically, this is the perfect counterpoint to what OP is questioning.

@Night FM: please answer my question. I agree, @dimreepr: give clear arguments, do not react with cryptic (and satirical) one-liners, or just let it be (speaking words of wisdom...)

People are missing one important factor: when the asteroid disintegration will occur. The Earth, moving at ~30 km/s around the Sun, and a diameter of ~12742 km, moves away by its entire diameter in just ~ 7 minutes. In order for all the parts of a disintegrated asteroid to hit the Earth, the disintegration would have to occur in less than just a minutes before the final impact. Which is highly unlikely, if humanity makes any attempt. Most of the Earth's surface is ocean. Most asteroids and meteors that hit the Earth's surface end up in the sea. The impact of a large object in the ocean creates a high tsunami, and the energy is dissipated over a very large area, and coastal areas are most at risk.

For aid to the OP cosmic time which is the standard for the FLRW metric used to describe our universe is of the form. \[d{s^2}=-{c^2}d{t^2}+a({t^2})[d{r^2}+{S,k}{(r)^2}d\Omega^2]\] \[S\kappa(r)= \begin{cases} R sin(r/R &(k=+1)\\ r &(k=0)\\ R sin(r/R) &(k=-1) \end {cases}\] An important relation is the critical density relation \[\rho_{crit} = \frac{3c^2H^2}{8\pi G}\] the equations that detail the FLRW metric acceleration equation are below. \[H^2=(\frac{\dot{a}}{a})^2=\frac{8 \pi G}{3}\rho+\frac{\Lambda}{3}-\frac{k}{a^2}\] now in the first equation the proper time is the \(-c^2dt^2 \] term above. However in order to understand how that time component is used by the FLRW metric one has to also understand which class of observers are involved and how the cosmic clock is connected to the Hubble flow (commoving time). As opposed to how SR or GR handles it. GR in this metric the time dependence is directly tied to the scale factor a(t). This wiki link actually has a half decent coverage of the time component of the FLRW metric. https://en.wikipedia.org/wiki/Friedmann–Lemaître–Robertson–Walker_metric

And you must understand the basics of deduction and learn to read with comprehension.

Thanks, I will... It makes me feel better; what's your excuse?
