Gliese 710 is saying - "Just stay there, I'll be with you sooner than you think..."

...this star will arrive 70,000 years earlier than expected, according to Gaia data.

Note that Gliese 710 would disrupt any wormholes in that segment of the Oort cloud, as well as causing a cascade of comets in real life.

This makes me wonder. If an advanced civilization were to leave a wormhole in the outer reaches of a star system to be discovered by a future civilization, would it make sense to leave the wormhole in its deployment state to protect it from things like this? My thinking is, a wormhole with a diameter of only a few picometers might have an exclusion zone much smaller than a full sized traversable wormhole and thus be less likely to interact with a star or planet and implode. Also, if a wormhole this small were destroyed by the encounter, the impact on its system would be reduced, as it would have less mass-energy to release.

Imagine if the Nexus already existed and all the Terragens had to do was figure out how to inflate the wormholes to traversability. Then the Terragen sphere might cover a galaxy or two by the current era.

We've gotta start building space arks now so we can get to Zyra!

A really interesting idea. This would make an intriguing Alternate History scenario for the Cyberians to model. And maybe it has happened in some galaxy within visible range; a MEEC civilisation might suddenly expand across a local group of galaxies, after discovering a mothballed nexus.

Hm. Although 70,000 years (60,000yrs by Y11k) is still a long time even by Terragen standards, it is within the range of the anticipated lifetime of Terragen civ and the archai. Given that we describe the use of various techs to move stars in the setting, it seems moderately probable that someone has taken it upon themselves to shift Gliese 710 into a more convenient path. Assuming they don't decide to just take it apart and remove the issue altogether. Or maybe they're still discussing it?

Thoughts?

The expected encounter with Gliese 710 will occur in 1.29 million years, instead of the previously calculated 1.36 million years; hence it will occur 70,000 years earlier.

I was sceptical about this event, especially since the star is currently 63 light-years away; how can they predict this stars' motion so far into the future? However, using Gaia data, the brothers Carlos and Raúl de la Fuente Marcos have calculated a range of potential encounters for this star- and they all occur within the boundaries of our Oort Cloud. This is likely to be the most significant stellar encounter for the Sun in the next twenty million years, at least.

Agreed! File these under 'article ideas' (as it were) Smile
