Because in that era they had a TIME MACHINE that they took and went back to the first era where the cavemen were fascinated by the machine that they killed them and stole it and went back to the third era and they took hostages back with them so yeah they did make it
Pressure and gravitymay have become unbalanced in thesolar nebula because of an externalforce such as a collision of the solarnebula with another nebula or from anearby exploding star. This type offorce, was strong enough to overcomethe pressure of the nebula and triggerits collapse.
A nebula collapses primarily due to gravitational forces overcoming internal pressures. As the gas and dust within the nebula begin to clump together under their own gravity, the density increases, leading to a rise in temperature and pressure at the core. This process can be triggered by external events, such as shock waves from nearby supernovae or the collision of molecular clouds. Eventually, the collapse can lead to the formation of stars and planetary systems.

An absorption nebula is a dark nebula, which absorbs all incident radiation without reemission.

In space and time anything is possible. Within our lifetime, then it will not happen, however in about 2.5 billion years the Andromeda Galaxy will collide with our galaxy, the Milky Way.
A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas

The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.
