Actually, what I meant was:
Science is haaaarrrddd.
The current goal is not to travel to an Earth-like planet. The goal is to simply find one. Which it appears we have.
Maybe in the future if we figure out a good method of travel we might start thinking about traveling to all those Earth-like planets we found.
Who cares, its finally an interesting enough target for us to actually think about building an interstellar probe. The sooner we launch one, the sooner our descendants build a better, faster probe that will outrun the first.
This is the part that confuses me. As I get older I am noticing that I have lost my twitch reaction speeds, so I can no longer play Quake, or Team Fortress very well. However, what I have lost in speed reaction, I have gained in cleverness. Having played a lot of games and seen how mechanics work, I am able to more quickly come up with solutions to problems via "Out of the box thinking".
Now I am curious if anyone else is the same way, I suppose that now that I am forced to move more slowly, my brain is counteracting that by helping me strategize more quickly. Maybe it is just a part of my inner workings, but I doubt I am any more special than anyone else.
Can anyone confirm/deny this for themselves?
In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the Solar System
Just like I said. And since you never gave a counter argument, that must mean you agree with me and/or are a troll. So I suppose that is it for this lovely conversation, have a fantastic day.
The curved path of a celestial object or spacecraft around a star, planet, or moon, esp. a periodic elliptical revolution.
You are really starting to look like a troll at this point, so maybe you should just call it a day, mate. If, however you are not trolling and simply misunderstanding, then please say so, I would be glad to help you understand.
I'm not sure that holds up.
Why not? He never said anything about the barycenter, which would move anyway. The sun being the center of the solar system is correct, regardless of the precise orbits of the planets. They all orbit around the most massive object here, which is the sun. In other single star solar systems, it is the same way.
However, if we had a binary system, I would definitely be with you on this one, how would one determine the center of the solar system then? I suppose perhaps the barycenter of the two stars would be used in that instance, but I really have no idea.
My favorite choice is this one: You can also use magnetic fields to decelerate or redirect
Just imagine being able to catch one of these things... "Thanks for all the energy! We really needed it to charge up this high-powered death laser."
