josellama2000 Posted July 11 #2 Share Posted July 11 The beauty about reality is that it seem like it was made for space faring as the relativity shows. On the other hand, it is all about energy that technology will allow us to manage if we survive the nuclear war that probably will happen during the next 5 years. 1 Link to comment Share on other sites More sharing options...

At 4.2 light-years from Earth, Proxima Centauriis the closest star to our planet other than the sun. Since Proxima Centauri is 4.2 light-years from Earth, it would take approximately 6300 years to travel there using our current technology..

You'd need to be going at 450,000mph which is far beyond the 24,791mph achieved by Apollo 10. 3 Link to comment Share on other sites More sharing options...

You need to cite a source when quoting offsite, there was no indication that your post was copied and pasted from elsewhere. The same source also says: Quote Apollo 11 travelled at around 40,000 kilometers per hour, a speed that would take it to Proxima Centauri in over 100,000 years. Which is consistent with my calculations in the video. The 6,300 years figure they've come up with is based on non-specific "state-of-the-art space technology". No current manned space vehicle travels at anywhere remotely near these speeds. Link to comment Share on other sites More sharing options...

In any rate with our current technology it would require a generational ship to travel the distance to our nearest star. Even in this case our current technology would not be able to over come many issues that allow one to be built. I personally don’t believe that our species will ever acquire the ability to travel at the speed of light, in my opinion the Einstein-Rosen bridge ( Wormhole) hypothesis is much more likely in our future because the mathematics bears it out.

Well, with our existing physics it is based on what we have been able to test and verify. Lets take dark matter. Galaxies rotate too fast for their gravity to keep them together according to general relativity. But does it really exist? Maybe our understanding of gravity is wrong. Or maybe, just maybe, our understanding of mass is wrong and the outer arms of galaxies doesn`t weigh as much as we think they do. I`ll go with that one and point out something completely unverified in physics - the idea that the Higgs Field (which gives atoms a lot of their mass) is the same strength at all points in the universe. Maybe, just maybe, it is a field that radiates from stars. If so the declining strength of the Higgs Field as we head out from a galaxy means things don`t way as much. Easy to test, and in fact we already might have the evidence as the Voyager probes aren`t where they are supposed to be. If mass decreases as we head out from the solar system then instead of it taking 4.2 years to get to Alpha Centurai B, for all we know it might be possible in a fast enough spaceship to get there in a few weeks. Of course, that means light (aka photons) are not impacted in any weight by the Higgs Field to explain why it still takes it 4.2 years to cross the void of space. 1 Link to comment Share on other sites More sharing options...
L.A.T.1961 Posted July 12 #9 Share Posted July 12 The time it takes at non Sci FI speeds to travel interstellar distances poses another question for me. How big a ship would I want to be on for the trip out. After thinking about it I am quite surprised at my own answer, which is about 250 square miles of usable space. Anything less and I would worry about getting cabin fever. 🤪 2 Link to comment Share on other sites More sharing options...
