Age of the Earth research. Most geological samples from Earth are unable to give a direct date of the formation of Earth from the solar nebula because Earth has undergone differentiation into the core, mantle, and crust, and this has then undergone a long history of mixing and unmixing of these sample reservoirs by plate tectonics, weathering and hydrothermal circulation. All of these processes may adversely affect isotopic dating mechanisms because the sample cannot always be assumed to have remained as a closed system, by which it is meant that either the parent or daughter nuclide (a species of atom characterised by the number
Evacuate Earth propose that colonists will eat insects and algae, which are easily replenished and space efficient. The ark ship launches and quickly speeds away, a few days later the neutron star is close enough that its tidal force begins to deform the Earth's core and the crust, which causes massive earthquakes and volcanism. Next, the gravity from the neutron star tears away the surface, causing the crust to shatter and the hot interior of Earth to spill out into the vacuum of space, destroying the Earth, but only the colonists on the ark can witness this event, as the rest of
