Human consciousness won't exist beyond the stellar era where the last remaining nebulae have been consumed by the final generation of stars in a vastly cold, dark and empty universe. The last surviving star will have exhausted all its nuclear fuel and become a white dwarf star that will then eventually cool down to a black dwarf star which no longer emits any substantial light or heat. The protons of planets and black dwarf stars will then eventually decay into subatomic particles. When all the protons have deteriorated into free leptons, then the only other remaining matter will be photons and neutrinos. Only extremely low energy photons, electrons, positrons and neutrinos will exist in the final phase of our universe. Each particle will rarely if ever interact with any other particle. There will be no events to mark the passage of time. Coherent structures, objects, sources of energy or sinks of energy will have ceased to exist. The universe will have then achieved its state of maximum entropy. Indeed, our universe is structured in such a way as to reach a state of thermal equilibrium where any life won't exist. Because of the second law of thermodynamics, the possibility of eternal life is zero. Life is very temporary, so please do enjoy it while it lasts.
All that I am has always existed in one form or another and I have no doubt that all that I am will continue to exist in this eternal and boundless cosmos.
Nor do I accept the theory that this universe will achieve a state of maxim entropy. This universe which I believe is but one of countless universes within the boundless cosmos, each occupying their own individual positions in SpaceTime, each beginning in an event that is called the BB and each, eventually falling into a Great Abyss, [SMBH] where they are ripped to pieces and reconverted to the electromagnetic energy from which they were created as that energy is accelerated across an Einstein Rosen bridge [Worm Hole] to speeds far, far in access to the speed of light and spewed out of a White Hole somewhere beyond the visible horizon of the Cosmos
in the trillions and trillions of degrees only to be resurrected in a different position in Space-Time, to where the light from its old position would take billions and billions of years to reach it.
Enoch, the only man recorded in the Scriptures to have been carried to the throne of the Most High in the creation, and who was anointed as his successor, was then escorted to the ends of time, where he witnessed the universe burn up and fall as massive columns of fire, beyond all measure in height and depth into the GREAT ABYSS, which is described by Enoch, as the prison of all the stars and the host of heaven, beyond which, there was nothing, not even the space in which the universe had existed.
In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea of black holes and worm holes, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance; Billions of light years to mere metres.
According to general relativity, the gravitational collapse of a sufficiently compact mass forms a singular Schwarzschild black hole. In the Einstein–Cartan–Sciama–Kibble theory of gravity, however, it forms a regular Einstein–Rosen bridge.
The gravitational collapse of a single star such as the star of our solar system, can form a White Dwarf, the gravitational collapse of bigger stars can create a neutron star, or a Black Hole, depending on its mass, but not necessarily a Worm Hole.
A worm Hole could theoretically be used as a method of sending information or travelers through space unfortunately, physical matter which includes humans journeying through the space tunnels would appear to be an impossibility as there are strong indications that material objects travelling through a worm hole is forbidden by the law of physics.
But now that it has been proposed by Quantum physicists that Physical matter is but an illusion, and all is, but the eternal energy, perhaps one day new technology may develop a way to teleport bodies of energy along light beams and reconstruct them to their original form, with no damage done.
Wormholes may not only connect two separate regions within the universe, they could also connect two different universes.
But then, Each to our own.
