7 "earth-sized planets" orbiting a dwarf star a mere 40 light years away.
This could prove to be very interesting.
Wonder how long before they start booking tours.

Well, since round trip would be a minimum of 80 years, that could be a problem.

That's all relative.
Assuming you start out at the speed of light and quickly return, not all that much older at all, but the Earth you return to and everybody has aged 80yrs.

But you'd have the tiny problem that to be traveling at the speed of light, you'd have to be pure energy. How would you get your mass back?

We have two new engines in development, one has been deployed and one is still being tested:

Have you calculated the time it would take to reach light speed with the thrust that thing produces?
