This essay will explain the challenges of interstellar travel, the prospects and limitations of existing propulsion ideas, and the prospects emerging from science that may one day provide the …

SETI researchers routinely subscribe to the view that interstellar travel between civilizations is exceedingly improbable due to the velocity-of-light limitation, with but few dissenting views …

Now, however, physicists are coming closer to finding out how, in some situations, light may actually travel faster than that. And, there seems to be ways to theoretically circumvent the …

Most scientists doubt interstellar travel because the light barrier is so difficult to break. However, to go faster than light, one must go beyond Special Relativity to General Relativity and the …

It is also possible, Boeing admits, that "classified activities in gravity modification may exist". The paper points out that Podkletnov is strongly anti-military and will only provide assistance if the …

Interstellar-probes.org This page contains a guide to the resources needed to study interstellar probes, interstellar travel, interstellar propulsion systems, the search for robotic interstellar …

I think that interstellar travel for biological beings is a long shot frankly, but if you’re either willing to send telesensing apparatus, or just spend a long time getting there, then going to the stars is …

After all, the assumed unlikeliness of interstellar travel has become the cornerstone of those who resist the ETH as an explanation for UFOs. So, does extraterrestrial visitation necessarily …

The Leading Theory-Based Rejectionist Argument (which we all know) The speed of light is a universal upper limit. Distances between stars range from 4.3 light years to Alpha Centauri to …

The implications of the Alcubierre warp drive for science fiction are fairly clear. If the theoretical and engineering problems outlined above could be overcome, we would have FTL travel, fully …
