July 24, 201511 yr It's completely dependent upon whether or not we develop faster-than-light travel or, at a bare minimum, faster-than-light observational technology so that we're at least not studying reflected light that was emitted from a star over a millenium ago. ... or, I suppose, if what- (or who-) ever is living on that planet has those capabilities and makes it known to us. Even if we find traces of life right now, it would be traces from 1,400 years ago so who knows what condition it would be in now or if it even still exists. 1400 light years, right?

July 24, 201511 yr Yeah anything that we would see today would have originated 1400 years ago and the light we see has been traveling at the speed of light 1400 years to get to us. I read once that many of stars that are visible from earth may have already died out 1000-10,000 years ago...but the light was still traveling here so we still see them. So a Star 16,000 light years away could burn out and it wouldn't disappear from our sky for 16,000 years.
July 24, 201511 yr I heard today that the mass of our cousin planet was such that we would weight at least double what we currently weigh on Earth if we were to walk on that planet.
July 24, 201511 yr What I find fascinating is they can tell how many days the planet has per year. It's all physics. They take the size and the distance from its sun etc. it it is pretty cool. It could be buzzaro earth....or maybe we are its bizarro world which explains a lot, like how the Kardashians are famous etc.
July 25, 201511 yr 1400 light years, right? Well a light year is a measure of distance. It's the distance a "particle" of light travels in an Earth year: about six trillion miles. So the light that has traversed that distance originated 1,400 years ago.

I can barely wrap my head around that. :lol2: Crazy...
July 25, 201511 yr Does the new planet have the All-A Tournament? Depends if all sports have classes or not.
July 25, 201511 yr Without reading the article how long would it take us to get there with our technology? ?
July 25, 201511 yr Without reading the article how long would it take us to get there with our technology? ? NASA - Warp Drive When - Scaling Consider, our nearest neighboring star, Proxima Centauri, is 4.2 Light Years away. The Voyager spacecraft left the solar system at 37,000 miles per hour. At that speed, it would take Voyager 80,000 years to reach Proxima Centauri. Doing quick math I think the answer is 2,6666,666 years or about 2.7 million years. Again, that was quick math, I didn't think it though, and I need one of you smart guys to calculate it. In short KJ, a long time.
July 25, 201511 yr Author What would be more aggravating, not knowing if there is other life out there, or we find life and somehow be able to communicate with them, but never be able to see them?
