My revised future world timeline

I revised my future world that will happen after the Information Age. Here it is.

Era 1: Post-Information Age (2020-2040) -the immediate future. 20 or 30 years or so Era 2: The Fusion Age (2045-2055) -the advent of fusion power eliminates the need for fossil fuels and ushers in an age of unlimited energy Era 3: Nano age (2055-2070) -Nanotechnology truly takes off and permeates every aspect of life Era 4: Interplanetary Age (2070- 2150) Humanity explores the solar system and establishes bases on the moon and Mars Era 5: Interstellar Age (2150-2180) -The invention of Faster than light travel allows humanity to explore the galaxy Era 6: Intergalactic Age (2180-3000) -Humans learn to transverse the intergalactic void and explore the universe Era 7: The Energy Age (3000+) -Humans learn to convert themselves to pure energy. Humans begin to live in their own designer universes

This is my outline of the future. What 5 inventions/technologies/developments/discoveries can you think of for each era?

My thought is that, when they become energy, they risk becoming black holes by associating too closely with each other. Either by proximity or through communication, the energy humans cause a Big Crunch and existence starts over.
