I am not late to this because the heat death hasn't happened yet & there is still time.
Idea's:
- Compress portions of the universe and stir up inside energy using less outside energy.
- Slip into another dimension and avoid it all together
- If the universe is expanding, creating new matter and energy, then keep traveling where new energy is being created and gather it
- Somehow manipulate the force of black holes
We just need to brainstorm outside the box & realize that new information may disprove it all together or bring more solutions. Any more idea's? No matter how ridiculous they might sound? A ridiculous idea could snowball into a bigger idea with some group brain storming.
