Wormhole to Another Galaxy

I found this post today that talks about a wormhole to another galaxy that might be located in the center of the Milky Way. It’s an interesting article, it makes for fun speculation, but it had a sentence in it that gave me pause:

“But there’s more. We could even travel through this tunnel, since, based on our calculations, it could be navigable. Just like the one we’ve all seen in the recent film Interstellar.”

I reviewed that movie and enjoyed it a lot. In it, astronauts traveled to Saturn to enter a wormhole that connected to another galaxy. You can travel to Saturn in a few years, as they did in Interstellar. However, to get to the wormhole in the center of the Milky Way, we’d have to travel about 26,000 light years first. At the speed of light, we’d get there in 26,000 years. With space travel technologies we have today, we could get there in a few million years at the very best.

So writing the nonchalant sentence “we could even travel through this tunnel” makes it look just a bit too simple for me.

The trip to the other galaxy through the worm hole and back would take longer than it took for our prehistoric ancestors to climb out of the trees, enter the savannahs and eventually become space travelers.
