How To Increase Net Speed Of Idea?

A Question about Indestructible Metal and the Fastest Speed?

• Can anyone build such a metal, or its derivative, which doesn't melts in presence of Lava, which doesn't corrodes, which cannot be destroyed Easily? Also, how to achieve a Fastest Speed when travelling in the Universe. From khanacademy.com I came to know then even if a Space Ship travelling at 1000 KM/ Hours from Earth, it would take 40 years for that Space-Ship to reach the Sun, and we can think of other huge distances in the Universe? So if we want to go near these heavenly bodies and observe it more closely, we have to find some other new method to achieve speed, and use energy. But is it possible to invent such an Indestructible Substance (Like the Space-Ships found in Star Trek and Star Wars) which can go and enter any hot and cold matter in the Universe? And how to achieve a speed 1000 times faster, then from what is today, and what fuel and Technology should be used? Because First Law of thermodynamics tells that Energy can be only obtained if work is done by the system, which means there cannot be invented a perpetual motion machine, which can produce energy without doing work. And what about Heat? Thermodynamics also tells us then in transformation of work into energy, some energy is lost as Heat from the system into the surroundings, and a permanent change is induced in the body? Also Einstein's famous formula tells us that Energy and Mass are related by the Square of Velocity of Light, so if the Speed is kept on increasing, mass will also increase and the body will keep on becoming heavy. So is it possible to create an Indestructible Metal Substance to withstand everything in the Universe, and also is it possible to invent a method to travel little less but not far away then the Light Speed? What are your researches and Ideas on this subject, I want to know, because something big cannot be done by simply one Idea, many Ideas and Efforts make a team and team Wins. So I want Long Answers like anything with as much detail and precision as possible. TO DARKER PRAIRIE : - Thank you for writing a Long Answers, which I asked for (I still want more and more Long Answers, from other Users Too, which increases the Imagination, Possibilities and Curiosity. And Yes, no Doubt my Question is Science Fiction, But many Sci-Fi Ideas in Past have made into reality. For Example : - Arthur Clarke and Jules Verne describe satellites in their novels and we have them today. 2) There was a Roger Moore James Bond movie in which a Space Shuttle was abridged on top of a Jumbo - Jet Aircraft, and today we use such a method (though I don't know which method it is) I also have a philosophy analogous to this Question of mine that. The statement is : - "Is it possible to achieve anything by Human Mind, if the limits are pushed. Or is everything Pre-decided and we are just part of a big script"

• Answer:

  My, what a load of questions. Definitive answers to most of these would assure you of an eventual Nobel prize, you're aware. What you are seeking is a #2 General Products hull (look up in wiki, "General Products Hull"), and we just sold out. (You do realize that we are in the realm of science fiction here, do you not?) Many metals can withstand the heat of lava (between 700 and 1200 degrees C). None corrodable? Perhaps. The problem is not so much providing a solid barrier for you as it is to make sure you don't bake to death, or at least have heat prostration. So, in addition to the solid shell, you would need insulation and positive cooling. Yup, speed is a big problem for space travel. So, in the absence of a magical space warping drive, you have to settle for alternatives. Note that the long time required to travel to, say, SGr A (the center of the Milky Way galaxy) is noticeable only to the observer back on Earth. From the point of view of the traveler, he can make it by dinner, if his spacecraft can be accelerated sufficiently close to the speed of light. He'll be there by dinner, while back on Earth 25,000 years + has passed. Another approach with more modest speeds is to use a generation ship, in which you may not make it to the target, but your descendants will. As for energy and, perhaps worse, reaction mass, there is one approach I like: that's the Bussard ramjet (see, for example, James Hogan's Voyage from Yesteryear). It reaches out and collects hydrogen and other material in front of the ship, funnels it into the engine where the hydrogen is fused into helium and all is then ejected. The fuel and reaction mass is gathered, not carried, during the flight. The problem with this is that the mass has to be accelerated up to the ships speed before it can be "fired", largely negating the energy gain. Oh, well... Is all this possible? Hard to say...would you have said electricity as a common energy source was possible 300 years ago? We don't, at this point, know nearly enough about materials to predict what might be done with them in 100 years, let alone a thousand. Or with energy, or genetics, or ... most anything. The only certainty is that we'd be surprised.
