Yes thats special relativity, constant speed only, no acceleration, so with special relativity rules only, one cannot turn around. However the general relativity handles it. And there is a difference between the twins. one feels the acceleration and deacceleration and the other not. Another case sitting in the near of masses also slows time down. So one twins sits next to a star while the other stays on earth. They will be different old.
I don't know why different old twins are a paradoxon at all. Just because it doesn't happy on a day by day basis in our lives?

Travelling into the future is no big deal, only technical. theoretically just jump to near light speed a short while, jump back and thousend years will have passed on earth.
However travelling into the past _is_ a big deal, as it questions a lot of physical fundamentals. What about energy conservation? Would the energy of the matter vanish out of the present? Would it pop out in the past. The particle of course already existed in the past, will exist then twice there? As I've now in the past two times the enery of the particle, have I created new energy?
Simply take a machine that transports a neuron back a second in time, 2 Neurons will exist then in a second before, put the time machine will still run there "a second time", so 3 Neuron will exist a second before, a second later the time machine will again send a neuron back a secnd. 4 Neurons will exist, so on and so on.

you're seeing million-year-old light outside, for instance:)
million year old light? time meassured from which observer? There is no "global time" Note that someone hasting behind the explosion light with say 99,99999...% of it's speed only some minutes have passed from destruction of the star until it reaches earth.
Does light (which travells at light speed) have age at all? Does light now what time actually is?:o)
As I see the flash light coming in from star, it happens NOW for me. I anly need to think that if I want to go there (with (nearly) the speed of light) twice the time will have been passed there, since the travel of the light took time (from view of the star) to get here. With 99.999..% travel speed I will also arrive within minutes in my time. Bet if going back to earth I would have to face that for twice the distance time will have flowed there. (1.000.000 years then)
Well actually you're facing the same problem many have whith special relativity. (including my prof.:o): To realize that there is not one "true" universe where space and time counts, but every point sees (or even has) it's own universe.
Well in the non existing global universe you could say that the star exploded 500,000 years ago, but this view is irrelevant. For us 500,000 light years away, the star explodes "right now" in the moment we see it's flashlight. Or receive a massive neutrino impact the day before. (Thats not because neutrinos travel faster than light! But because the star stars sending them a day before it explodes.)
Again every point has it's own universe. You can feel it mathematically if you take two equations, which hold both true but for two different obversers and substitute them toghether, you get math. nonsene like 1=2. Thats because bath equations may be true, but not in the same "universe". As Einstain proofed this even goes further, as there isn't even global simultaneousness, things that way happen synchron for one observer, way be seen in sequence by anoter observer, or even in reverse sequence by yet another observer.

Just a nitpick: Mars' atmosphere is already over 90% CO2, I think. So what you actually need to increase is its density.
Hmmm might be:/ mars it too light.
Honestly I thing venus would be a far better target for terraforming. It's currently completly unsuitable for station there, we know. Thousend degrees is not comfortable, places where metal smelts. But aside that little problem it's perfect. Same weight than earth, nearly same materials, only in it's evolution something went another way than earth did. BTW: It's not so hot there because of the few kilometers that it is nearer to the sun, it's so hot there because glashouse effect went into a self recursive state there. (planet is prinicipally in a stable state, but of some reason it gets a bit warmer, some water vaporizes, since H20 is also a glashous gas, it get's warmer to the H20, more H20 vaprozies, warmer again, so on until at some point the water boils, you have a perfect glashouse, temperature skyrockets, metals smelt and some vaporize, they are also glashous gases, temperature rises more and you come to the second stable planet state venus is now.)
Now the idea is to get the planet back to the earth like state, maybe a bit more warmer since it's really nearer to the sun. (I think from the higher light impact it should be calculated only 20-30 degree's or such.) (not the tousend it has currently due to the glashouse) so with aprox. 40 on some places it would be a nice place to be.
The thing needed would be a "designer baktereria" that could live and exist at the outher atmosphere of venus, it would be a plant, with photosynthesis capabilities taking enery from the sun, splitting CO2, into O2 and uses the gained energy and carbon (C) to reproduce itself. As the bacteria reproduces and spreads itself more and more oxygen would come free, temprature would drop until to more comfortable values, there would be more space to life for this bacteria (or fellowers). Temprature would drop again, metals would get solid, water condenses into oceans, until we've earth like status there. Life habits would have changes so strong this designer bacteria would no longer be able to surve and die out. Now the planet is ready for humans to come by, brind their trees and crops, and plancton for the oceans to replace the 02 generation and be happy.
Sounds easy or?:o) Now just have to get a plantlike bacteria that can live at several 100 degree's and has some simple "float/flight capablity" to stay in higher orbit and not to fall on ground where death comes quick. After this is done, just shoot a small probe at venus, at wait 500 years:o) (or a bit more)
