So, scientists seem to have found a very interesting neighborhood that might prove to be worth exploring.

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.

We have two new engines in development, one has been deployed and one is still being tested:
NASA Extreme No Fuel Quantum Engine Actually Works

and the EM Drive:

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

Naah. I have my bets placed on this system:
