>>7613170If and only if there was a sun "made of" ice (great terminology there, anon), it would melt before ever hitting the sun "made of" lava (given both are equal in size), so crashing into each other is kind of impossible or at least irrelevant.
Other problems: lava is what magma is called when it erupts on earth's surface. So, no sun made of lava this is wrong terminology (if anything, then plasma).
Last thing to consider: A sun (or for that matter, any medium) will only emit light when reaching or surpassing a specific temperature (few hundred or thousand degree celsius, I can't remember anymore), ice will never be hot enough to emit light, something that a sun does by definition. It would thus be an ice planet.
But still an entertaining question, not what I'd call humour though. There are much funnier examples in this thread such as >7613176 Well done anon, well reposted.
