would you believe that this could be done if the object was a cylinder , simple and strong in structure , made from a new kind of artificial crystalsomething similar to diamond , except that it could , with respect to the alignment of the molecules , withstand trillions of times more pressurealong with a cork of similar , but weaker , material that would , after slight melting from the surface temperatures of the star , fit into the mouth of the container and then solidify into a perfect seal ?
