<br />you can actually see (fairly) clear evidence that this huge basin was made after most of the "shoulder-to-shoulder" craters in the southern hemisphere. Around the border of the basin in the "blast zone," I guess you could call it, you can see the older surrounding craters in various stages of being buried or vaporized by the Hellas event. <hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

If you look at a cropping of the Hellas Basin from the high res MOLA in the attached link (still too big to post), you can clearly see that the areas where I've drawn the outline of a circle have been covered over. The other smaller opaque circles that I've drawn are clearly more recent, and can be found both in the crater and in the northern hemispere.

<br />I thought the Tharsis region was formed as a consequence or reaction of the catostrophic event. Like when you punch a beachball and there's pressure on it on the other side to bulge out. So are you saying that the Tharsis bulge was caused by the second oxplosion (Body-C)? Can you give us some reference on the formation of Tharsis that would be consistant with your model?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">I have never made a serious effort to sort out whether Tharsis was created as an aftermath of the big pole shift following the Planet V explosion, or as a consequence of the smaller, more recent Body C exploson. I can think of reasons that might support either hypothesis.

An important element in deciding this point would be to carefully map out the great flood boundaries to more carefully define the hemisphere most affected by the Body C explosion. If it is an excellent match to the Tharsis region, then Body C probably caused Tharsis. If it is a better match to the old equator than to the present equator, then probably Planet V caused Tharsis and rotated Mars in longitude so that Tharsis faced Body C, awaiting the Body C explosion.

Another important element is the relative strength of tidal forces, which lead us to a hydrid theory. The tides raised by Body C on Mars were still significant despite the smaller size of Body C as compared with Planet V. This is because Body C was closer on average, because its orbit was elliptical making tidal variations greater, and because tides continually increased in strength as Mars and Body C interacted in mutual orbit (because of orbital tidal friction, which worked to shrink the orbits). So even if the Tharsis volcanoes went dormant following the Planet V explosion, they would have been re-activated as tidas grew in strength, finally becoming so strong that they triggered the explosion of Body C. -|Tom|-

<br />An explosion this large would take perhaps a dozen minutes to happen, and the blast and debris waves would be dozens (?) of minutes to hours thick as they swept past Mars, and thicker still as they spread outward beyond the local area.)<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">I'm not sure what your point/question was. But don't forget that Mars and Body C were spin-synchronized to always face Planet V. So the finite duration of the blast wave would not have allowed impacts to spread very much beyond one hemisphere. -|Tom|-

<br />That's why I said I had a hard time picturing how taking refuge on the far side of the Body C was going to do anyone any good. Especially in light of what happened to earth at the K/T boundary.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">Taking refuge on the far side of a planet would have been only a temporary shield from the passing blast wave, not a way to survive long-term. And I no longer think the Mars-artifacts-builders could have pre-dated the Planet V explosion. They must have evolved on Body C following the Planet V explosion, following an evolutionary timescale similar to that proposed for Earth following the K/T boundary event. -|Tom|-

If that doesn't work you can do it the old fashoned way: <hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">


There's a problem with the way the software handles the "ltp" before the "www" (Tom just told me about it). So, for those interested if you copy this link into your browser, and then replace the "x" with the third "w", this will take you to the site of the High Res MOLA Map. Shift-Click on the legend below the Map will download the 18MB jpg.

Wow. This thread has really helped me understand the EPH so much better. Perhaps, Tom, you should write a historical narrative of the explosion events as they affected the solar system (specifically earth, Mars, and body C).

May I also suggest for clarity sake using more descriptive names for Planet V and Body C. Perhaps something like "Gas Giant V-65" and "Mars Companion Moon C-3.2" as these would help us keep in mind what they were and when they exploded.

In any case, I have a few more questions:

1. If V-65 was, indeed, a gas giant, what happened to it's twin planet ejected from the Sun?

2. After V-65 exploded, what kind of mutual orbit would Mars and C-3.2 have had? Would they have synchronized their orbits so one of them had one side always facing the other? If intelligent life were to have evolved in an "earth-like" way on C-3.2, I assume some type of stable orbit with tides and seasons would be necessary. Can you explain more about this?

3. Could the explosion of C-3.2 have occurred as a result of having taken on so much extra mass from the V-65 explosion? Would extra mass contribute to the graviton-heat theory of exploding bodies?

4. Similarly, could Mars be a good candidate for the next explosion in our solar system, having taken on lots of extra mass from two near-by explosions?

Thanks!
