The 100 Year Starship

I hope the future of interstellar travel is not these gigantic starships. It's like starting a project of building a gigantic Zeppelin in 1900 in order to get able to get to moon in 100 years. Teleportation seems more convinient to me and much less financially and socially devastating.

Sure, but there is that pesky problem where the solutions need to be theoretically possible.

Both teleportation and Death Star are impossible with current technology, but the folks anyway are building the Death Star?

Let me introduce you to the Nicol-Dyson Beams: https://www.orionsarm.com/eg-article/48fe49fe47202

This actually fits nicely with the name "Death Star", as you take all the energy or a star (via an orbiting Dyson swarm) and turn it into a concentrated beam of death.

a.) Who is building a Death Star?

b.) Death Star isn't theoretically impossible. We know you just need to direct a massive amount of energy at a planet to blow it up, the only question is figuring out how to get that kind of energy. Teleportation though, we literally have no idea how it would work or what it even means.

Engeneration is an interesting very high tech "teleportation" alternative:

https://www.orionsarm.com/eg-article/4a3d78dc77e6f

You basically send your digitized DNA & personality copy to the target (needs to have reasonably high tech infrastructure already in place), where a blank body is grown & "flashed" by your personality. And voila, you are now walking the surface of another world couple light years away from your destination. (And you likely also now effectively exist at least twice, but oh well.)

There are serious ethical and security issues with this technique, but it might still be useful none the less. :)

No I'm not, my clone is. My consciousness is right where it started, making this an extremely limited form of "travel"

Altered Carbon, gotcha.

"... a couple light years away from your transmitter"?

There's a lot more people with money willing to invest in a planet-destroying weapon than space exploration, unfortunately...
