This is happening 124 light years away from earth.

That means if we develop a way to make a space ship accelerate at 1g for a long period of time, you could go there in just 10 relativistic years.

Unfortunately, whilst science allows such a rocket, our engineering skills are far from being able to build one.

If you can somehow make a ship capable of constant acceleration at 1G, and had enough shielding on it to protect it against the radiation, you can travel to any point in the observable universe, in a human lifetime.

If you just keep accelerating and left as a 20 year old, you'd be in your 50s when you saw the final stars born and die in 100 trillion (earth) years time.

That's how crazy relativity and torchships are

That is the most believable but bizarre thing I've read today. Maybe this week. It's probably tied for the month.
