?No, astronauts have not "already found a planet like earth."
no, nobody has made a device that travels that fast without carrying humans.
Yup there is a planet , sorry for misunderstanding my statement what I actually mean is that they actually found a planet that can support human lives.
As I have said on the device, they already have been created a device that discovered the planet that I was saying. If they were able to do so then later on they can surely create a device that can travel that fast that also carries humans
No they have not. I also saw news reports that misrepresented the actual scientific findings.
Huge progress has been made in determining planets that lie in the "habitable zone" of other star systems, and even inferring a bit about their overall chemical composition. That's not nearly enough to guess at whether they can support human life.
But here's the latest research, which is really mind boggling. They've got frikking thousands of candidate planets....
