Tme Ends

== The end of the stellar era* ==
The last few main sequence stars in our universe are vanishing now. The only stellar-mass objects now remaining active are white dwarfs, neutron stars and black holes. Brown dwarfs also remain.
Planets everywhere have been dislodged from their previous orbits and left drifting as "rogues", with many ending up in black holes.
== Tellurium-128 reaches the end of its half-life ==
Tellurium is a brittle, silver-white metalloid which looks similar to tin. It is far more common in the universe as a whole than it is on Earth. Its extreme rarity in the Earth's crust – comparable to that of platinum – is partly due to its high atomic number, but also due to its formation of a volatile hydride which caused the element to be lost to space as a gas during the hot nebular formation of the planet.
Naturally occurring tellurium has eight isotopes. Five of those isotopes are stable. The other three are radioactive. Tellurium-128 has the longest known half-life of any known unstable isotope, at 2.2 septillion years, or 2.2x1024 years
== The degenerate era of the universe ==
In this era, the only energy being generated in the universe is through proton decay and particle annihilation. Neutron stars, white dwarfs and black holes are now the only remaining objects. Due to extreme age, all of the planets and moons have disintegrated and decayed into their constituent atomic particles, or else been absorbed into stellar remnants.
== The black hole era of the universe ==
Only black holes and subatomic particles remain. The universe has expanded so much that these individual particles may be separated from each other by truly enormous distances. Black holes themselves are now evaporating by Hawking radiation
== The dark era of the universe ==
The dark era of the universe
The last remaining black hole has evaporated.
From this point onwards the universe consists only of photons, neutrinos, electrons and positrons – with no way of interacting with each other. 
The universe continues to expand forever... but is essentially dead.
