That's what I was getting at. The effect is scales exponentially, e.g. going from 98 to 99%c is much worse than going from 48 to 49%c. Going 75-80%c isn't a huge deal in terms of time dilation (60% dilation at .8c) but is still uber fast. This is an often misunderstood concept in scifi and the equation is quite simple.

Doesn't mass increase with speed? I read Tau Zero as a kid and IIRC that was key to the story.

Most of the time that they are moving near c would be spent between solar systems where the odds of hitting even something tiny are extremely low. Once they reach the destination solar system they should be travelling well below c. I'm not saying it isn't a concern, but I don't think it's a very big concern.
Yes, which is why you can never reach the speed of light. You would weigh more than Jared before Subway!
I believe it was explained in the background material/Avatar Wiki (not in the movie itself) that the ship we see in the introduction is actually mostly made of synthetics to avoid secondary radiation caused by high-energy rays hitting solid objects (metals being denser than most other matter, so reducing them would thus reduce this problem)... Interesting idea. The engines for example is at the front of the craft (not the rear, as with a traditional rocket), with the rest of the vehicle hanging in tension from a carbon nanofiber truss-like stress structure.
It would reduce the need for consumables if passengers are kept in suspended animation. Less air, water, certainly less food needed!
And cost considerations seem to be a thread running through all of Avatar's human civilization (much like it is today I might add.)Yes, which is why it's so dangerous to collide with basically anything. Even single atoms become basically like pistol bullets at very high fractions of C IIRC.
There's no substance to any of the "food" sold at Subway. I've heard it said that Subway's business model is selling air that smells like food, and from my own two lone experiences, that is certainly true. I don't understand why people go to eat there, it's a massive con really.
Not that this has anything to do with this thread! Lol, sorry.

My favorite comedic observation about Avatar comes from Joel Hodgson, creator of MST3K.

I just finished watching Interstellar. Wow don't watch that movie if you hope to fall asleep and go to work the next day. I've never been through such a tension built movie in a long time since Requiem of a dream. Movie is good, the science seems to work out mostly, sorta, some parts break down. But it's quite an movie actually, as a father it got to me emotionally, and I think knowing that, their world could be our world one day is saddening.

The only reason why Interstellar isn't a good fit for a bedtime movie is the obnoxiously loud Hans Zimmer OST. I felt every last minute of that 3 hour monstrosity. When Catwoman and Magic Mike's buddie returned from their surface expedition, I felt a bit like the poor black guy they'd left behind in the shuttle.
And just to make the point even more dramatic :
At 99.9999999999999% of the speed of light in one day on the ship 61286 years would pass on earth
But you certainly have to account for the change in distance if you're travelling close to the speed of light. I.e. if you're travelling fast enough then from your perspective, distances shrink. A light year can become a kilometre at the right speed.
So... if I understand this correctly.
1 light year - is the distance light can travel in 1 year (365 days).
But if i moved at the speed of light, time dilation should occur, so I will travel 1 light year in 365 (days) to an observer, but the effects to me is that it should be notably less than 365 days?
not sure, you see at that speed time stops so it could be instantaneous or the opposite
