Some stars will last a really long time too. If the Sun gets too old, Proxima Centauri will supposedly last for over a trillion years and is within <5 light years distance. It could be reached using nuclear propulsion (e.g. Project Orion or staged nuclear-thermal) within a human life span.
The universe might be concluding its star-forming era but will be capable of sustaining complex life for trillions upon trillions of years. After that we don't know what really happens. Heat death is the depressing but most widely accepted outcome.
- JohnJamesRambo 5y agoOk this trillion number you are talking about makes me feel better about this article.
- api 5y agoYeah we have a good backup star <5ly away. In hundreds of millions to 1-2 billion years when this becomes a problem we (or more likely whatever descends from us or the AIs we build) will either be able to move easily or will be extinct already. AI intelligences would have no problem traveling between stars. Who cares if it takes thousands of years even... just turn yourself off. Even better send automated factories to build compute power and robotics and then transmit your minds when the new site is ready.
