welshbairn Posted August 8 Share Posted August 8 First and last we'll see of aliens is when they stop by to e=mc^2 Earth to top up their warp drive. I read elsewhere you'd have to convert the mass of a whole galaxy into energy for it to work, which would send the tree huggers mental. 0 Quote Link to comment Share on other sites More sharing options...
Doctor Manhattan Posted August 8 Share Posted August 8 2 hours ago, throbber said: This is the whole thing about the Fermi paradox. The Big Bang happened 13.8 billion years ago, the earth is 4.4 billion years old and humans have only been here some 2.8 million years. Whilst people have used the stars for navigation for thousand of years we only invented the telescope some 500 years ago and since then we have surrounded our planets with satellites and put men on the moon and are exploring further afield within our own solar system. If we carry on at this rate where are we going to be in 1 thousand/1 million/1 billion years time for example? We are surely quite late to the party given the scale of our own galaxy so why hasn’t some other life force made themselves unequivocally known yet? von Neumann probes "It has been theorised that a self-replicating starship utilizing relatively conventional theoretical methods of interstellar travel (i.e., no exotic faster-than-light propulsion, and speeds limited to an "average cruising speed" of 0.1c.) could spread throughout a galaxy the size of the Milky Way in as little as half a million years." 1 Quote Link to comment Share on other sites More sharing options...

Just wait until we start to use dark energy Quote Theoretically, a spacecraft that runs on dark energy is possible. According to a paper published in 2008 on arXiv.org, a dark-energy-powered spacecraft may be able to travel faster than the speed of light. https://science.howstuffworks.com/environmental/energy/dark-energy3.htm#:~:text=Theoretically%2C a spacecraft that runs,than the speed of light. Quote The spaceship would actually stay in place while space-time around it was affected. So instead of moving the spaceship really fast, you move the universe really fast. This is how the Eurostar trains work. 0 Quote Link to comment Share on other sites More sharing options...

Yes and the point is largely how far we have come in 500 years and how much of a drop In the ocean that time is in the scale of the universe. Assuming we progress at the same rate without wiping ourselves out then we will be unrecognisable even in 10 thousand years let alone half a million. Perhaps civilisations reach a certain level of evolution and then self destruct before they get explore galaxies or perhaps we are the most advanced species in our galaxy or perhaps other species are so far evolved they exist in a different dimension to us altogether. 1 Quote Link to comment Share on other sites More sharing options...
Bairnardo Posted August 8 Share Posted August 8 The infinite universe is presumably full of different versions of us, who with unerring regularity, destroy themselves long before they harness the technology required to travel beyond their own galaxy. I mean, we must be a good bit closer to our own destruction than we are to intergalactic travel by any measure. 2 Quote Link to comment Share on other sites More sharing options...

DA Baracus Posted August 13 Share Posted August 13 The technology to fire about the universe will never happen because it's impossible. Warp and all stuff is just sci-fi unfortunately and can never be a reality. No doubt at some point there will be a human on Mars but the resources and cost to get folk there is massive, so there's zero chance of getting folk living there, although no one would want to and it isn't possible long term anyway. 0 Quote Link to comment Share on other sites More sharing options...

If all the human race were to adopt this attitude then we would still be living in caves. 0 Quote Link to comment Share on other sites More sharing options...
