<p>This has always perplexed me about the impact of Shoemaker-Levy 9:</p><p>Being&nbsp;that&nbsp;Jupiter&nbsp;is&nbsp;a&nbsp;gaseous&nbsp;planet...what&nbsp;did&nbsp;the&nbsp;comet-fragments&nbsp;actually&nbsp;"impact"&nbsp;and&nbsp;how&nbsp;did&nbsp;it&nbsp;leave&nbsp;an&nbsp;impact&nbsp;"scar"&nbsp;that&nbsp;quite&nbsp;closely resembeled a crater on the surface if there IS NO surface?</p><p>Is&nbsp;the&nbsp;gas&nbsp;that&nbsp;dense&nbsp;that&nbsp;matter&nbsp;would&nbsp;actually&nbsp;react&nbsp;to&nbsp;it&nbsp;as&nbsp;if&nbsp;it&nbsp;were&nbsp;solid?</p><p>I&nbsp;just&nbsp;don't&nbsp;get&nbsp;the&nbsp;physics&nbsp;of&nbsp;it.&nbsp;&nbsp;Can&nbsp;anyone&nbsp;help&nbsp;me&nbsp;understand?</p><p>Thanks!!&nbsp;:)&nbsp;</p>
