h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Would interstellar travel create tunnels through regions of higher density ISM? Unlike supernova which may have a roughly spherical shock wave? If aliens were traveling through the interstellar media in our galaxy, would ISM tunnels give their existence away?

Apparently the local interstellar medium`s density is believed to be quite low, which unfortunately probably rules out any nearby tunnels being observed. On the other hand(or alien limb), using our local ISM, could save them quite a bit of what ever fuel they use, as less is wasted in their spaceships wake.

If we were to enter one of these unobserved alien light speed routes, do we run the risk of being fined (for a traffic violation)?

Is S.E.T.I.looking for entry and exit tracks produced by alien spacecraft as they pass into & out of, our local low particle density space? It may be more sensible to seek alien destinations, rather than search the entire sky?

Had a look at the S.E.T.I, web page, apparently they only look for narrow bandwidth carrier signals. Has anybody checked that these carriers actually get through our sun`s various charged particle bow shocks, without being scattered or refracted away from the Earth?

Noticed in a recent article in N.S. magazine that S.E.T.I. would like an observatory in space, to take advantage of gravitational lensing effects, which may intensify(alien) radio signals from outside our solar system, if they exist?

Relativity increases mass with velocity in a particular direction, and increases to infinity as v~c. Would not the relativity factor also permit mass to decrease again from infinity as v exceeds c, the factor`s imaginary component indicating the existence of a shock wave within what ever medium supports mass?

The surface of the alien craft in contact with the mass bow-shock would be relatively frozen in time, when at or exceeding light speed, but could time within the interior pass at a more normal rate if the craft`s surrounding body mass were to somehow shield the interior of the craft? Slamming sub-atomic particles together gives no clues as to what happens inside a large alien craft sized lump of matter when being accelerated to near light speed?

Inertial Mass due to relativity Mr=M(invariant)/(1-v^2/c^2). However high the Inertial mass of the near light speed craft becomes, its invariant mass within the craft is still invariant. See Lorentz LET. Can Matter really contract to zero length, or is it`s contraction somehow limited(an infinity of yet smaller lengths)? What if the E & H field medium has a definite particle size, or a limited size distribution?

Sorry, M(relative)=M(invariant)/(1-(v/c)^2)^0.5,kg. The Lorentz aether theory postulates an immobile (E & H)aether, but it could be that the aether is a gas like distribution of substance particle sizes. If E&H electric fields are waves within the aether gas, a projectile may cause a bow wave through the aether, causing a change to the refractive index?

Have near light speed, projectiles(ions/molecules) been observed producing a change to the refractive index as they pass through the vacuum?

If the E & H fields were to be vibrations within a gas like particle media, then superpositions (of higher density), could intercept more of the lighter, faster moving particles, of the gravity particle field; which may be an alternative way of describing the gravity lensing effect? Is a refractive index change similar to a gravity lens effect?

Could the side of a spinning disc rotating in the same direction as its center of motion exceed light speed, if the discs motion were close to light speed?

Relativity theory puts the breaks on, but is it right? If space-time is an emergent property of vibrating substance particles, then distribution of substance sizes within the gas like media, places limits to where the application of relativity can be expected to function?

See Ergosphere, the frame exceeds light speed, objects in the frame don`t?

Ergosphere is a volume of Space-time that is being wrapped (dragged) around a rotating Black-hole. If space-time contains a light carrying substance particle media within, then this media should not only flow, but have time like eddies between the boundary layers?

Since the Ergosphere theory suggests that space-time and hence the light carrying media within it, can be wound around an object, is this a possible explanation for an electrons up, strange, and down spins?

As space-time is wound around an object and becomes ever thinner, will it eventually snap? It well may, if it`s made from substance particles, which break apart into yet smaller substance particles. The best way to fill a space is to start with the largest objects (particles) first, then pack the next largest size of objects in the remaining spaces, and repeat with ever smaller sizes.

If gravity is due to the Le Sage type interaction between light-matter wave and gravity substance particle medias, then as space-time is wound ever thinner and the light-matter particle media is crumbled into a mixture of smaller particle sizes, this mixture should interact less well with the gravity particle media? Space-time changes with the ingredients in the substance particle mixture?

Nice pictures of space dust on the esa`s Planck web pages, but how would you go about spotting trails made by objects moving through the cloud picture?
