the mass of the planet seems greater the earth. the mass of the planet compared to earth and being close to a red dwarf I'm assuming it has more gravitational pull then earth? If so, I don't see how it'd be fit for human survival

I think in the future we will unravel the mysteries of spacetime and quantum physics which will allow us to travel at faster than light speeds.
You can't FTL travel as of now, could be possible in the future but right now, and for many years, even thousands. it is impossible and might even remain as such, According to relativity, it's impossible for any object with mass to Even travel at light speed.

The only thing that would keep us from personally going there is the gravity, but it doesn't mean we can't send probes to check it out up close.
Why would gravity be an issue?

IIRC, the surface gravity of a planet is g= G *(M/r^2) where G is a constant.

Since it's 5 times larger than Earth, depending on the Mass of the planet, I don't think it would be a big issue.

It's not five times the size. It's 5.4 times the mass, as I said "the size of 832-c (around 5.4x the mass of earth)".

The quote below solves your answer.
You can never travel FTL, because that would require infinite energy.

Though, we can avoid the problem by using something like:

This isn't that far-fetched, and NASA (and other groups) have already started preliminary research, and basic theory development.

We're still a very, very long away from this though. At least a few hundred (maybe thousand) years, because first we need to find a power source, and than we need to conquer gravity. No small tasks, but It's all theoretically possible.
Yes to exceed the speed of light, the object needs to be able to bend space but this takes an incredible amount of energy, something unimaginable for us now but maybe not in the future. Dark energy right?

We'll need dark matter, because of it's negative mass.

this is pretty cool, but 16 light years is not close. it would take 16 years to get there if we travel at the speed of light which is impossible.
Actually, it would take 16 years only from the perspective of 3rd people, spectators waiting on Earth. Considering Einsteins theory of relativity (or rather law of relativity, since it was proved to be true more than once) getting there would be a matter of weeks for the travellers. When you travel with the near lightspeed (since othe photons can reach full lightspeed) time just slows down that much for you.

Way too far, no evidence of having water, stronger gravity, possibly no oxygen.

It would take more than few dozen thousands years due to it not being suitable yet. We would have to make it suitable. And even that won't possibly happen because we haven't studied the planet enough yet.​

Even that has to be researched. And it's existence still hasn't been proven; possibly doesn't exist.​
