Quark Matter Blamed for Paired 1993 Seismic Events

Question is, what kind of hole would it leave behind? I would think a sort-of cell-sized one, and the hole wouldn't last for long, because the rubbery substance your body is made of would just splooch, microscopically, back in place. The hole almost certainly wouldn't be big enough, nor last long enough, for other blood cells to follow: i.e., it wouldn't bleed.

      Well, if you make the reasonable assumption that such strangelets are NOT generated in the solar system, then there is a minimum speed (somewhere in the ballpark of 50 Km/s) that is determined by the combined escape velocities of the earth and sun. Anything coming from interstellar space out of the planetary plane canno arrive traveling slower than this. Anything much over 10000 Km/s is probably not going to be detectable as 'traveling' by the researchers' criteria, because it will seem instantaneous (i.e. less than a second - how well are the clocks calibrated?) to the relatively sluggish seismic monitors. So that would be the range they would be able to look for traces in.

      Uh oh. The sun's escape velocity is 618 kps. This thing was doing around 400. Which means it may still hanging around. But the solar system's gravity fields are chaotic enough that it might get lucky and be slingshot away.

      Yeah, it'd behave just like any other piece of mass in the solar system, the only differences being that it's pretty much impossible to see and that when it hits something it doesn't go 'splat'. We _could_ make tentative guesses about where it'd be at any given time, but without additional positional data the potential for error would grow quickly.

    What about a bullet wound?

    Ok first of all a bullet is designed to expand and release it's engery in the form of expansion. Thusly thats why they have little holes going in and big holes going out as the bullet expands and releases alot of it's energy. Bullets that have a full metal case do not leave big holes at all.

    The other thing is like many other people have brought up that this is smaller than the size of a cell and has the mass of of aprox 1 ton. I do not know how fast it is going but I saw a post that said 400k/sec. If it does not have enough frontal area or expansion ability (very small very dense) it will squish in and snap back on the surfance and thusly cause vibrations but the hole it would leave would be extremly small. It would also produce vibration as it traveld through the object and came out the other side but agian probably not do much damage.

    Like that weapon they had in the movie "eraser" was total BS. It fired a .22 of an inch projectile at near light speeds. The projectile will not expand and thusly will not release much energy. Merely punch straight through both sides and continue on untill the engery runs out.

Your body structure is too dense for a bullet to pass through without energy loss, not true for a quark.

The giant Kamiokande and Sudbury detectors would surely detect even tiny quantities of quark clumps, should I dare say single quarks? No the skies have been clear of such powerful thingies unless a single quark can cause earthquakes, THEN we can say the chances of them hitting the earth are so small, that we only had one in 93.

    Secondly there have been enough earthquakes in earth-quake recorded history that we can expect almost simultaneous quakes sometime. The source that emitted even one quark of that much power towards us is likely a stellar event, sending more than one of these quarks or quarklumps. We should have had a series of earthquakes just like the leonids.

    Thirdly, as I imagine tiny centers of enormous gravity, me thinks it should really break the rigid structure of rocks and other crystal-like things. Say we have one tonne of mass, on how much area should we put it to have enough pressure to crush rocks?? I think a little under a square inch. Therefore a little circle of this ballpark size can be discovered (assuming the material was about a tonne's worth of mass. If more, we get lucky with a bigger powdery circle). The circle would be dark with a burn and so easily noticed. Then again, shockwaves would move enough earth (if the can cause an earthquake)to form little mound circle.

So when it exits the individual it has left a wake, but a small one because of its incredible velocity.

    This isn't billiards, where a ball transfers all its momentum to another, and it isn't like an ice burg where the oil station must be obliterated for passage. At 3e8 m/s it would pass through a meter of flesh in 1/3e8 seconds transfering energy to a few cells with very little mass themselves.

Thus the object enters and leaves the earth faster than the wave can propagate. To a seismograph, this would appear to be a long fault along the entire path the object took, rather than as a series of points along the path.
