Natural Science 301 Guidelines
This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.
As usual, Tweb rules apply. If you haven't read them now would be a good time.

Originally posted by QuantaFille View PostI know. It can send data back, that part I understand. So I asked, how do we maintain communication with a receiver/transmitter (which means two way) and you said it shouldn't be an issue. That's what confused me. I think you think I meant, how do we collect the data. I was thinking more like, what if you need to send the probe instructions? But you'd have to make it entirely autonomous.
A ship traveling at the speed of light would experience no time at all. Their journey would be over instantly for them.

Originally posted by Chrawnus View PostI thought that it would have been obvious that the implicit assumption in my post was that traveling at near lightspeed velocities is currently only theoretical for things such as spaceships, unmanned probes or other objects which are "suitably macro" (to make up a phrase that encompasses all objects which we are currently unable to accelerate to near-lightspeed levels.)
... that was thought was incredibly stupid.

We have found a better candidate for an earthlike world closer to ours than ever before.

Hotspur: Why, so can I, or so can any man;
But will they come when you do call for them? Shakespeare’s Henry IV, Part 1, Act III:

Another goldilocks planet found closer an earth like than ever before. . . but there is a problem. There are likely many earth-like planets everywhere, but at what stage are they in their development of their solar system. It depends on how mature the sun is. In our solar system both Venus and Mars were potentially living earth-like planets but no more. Earth-like planets have a life span as the sun matures, and eventually earth will no longer be an earth-like planet.
