  1. I should have said brain to size ratio, an elephant has a huge brain to size ratio compared to a triceratops but I've not seen anything to indicate either built dams with any intent or future planning. Beaver do how ever build dams specifically to make their lives better, whether or not they actually have the future in mind is debatable. The phrasing of the OP indicated some intent to build a dam not accidentally dam up a stream. Are you suggesting that triceratops pushed down trees with the intent to dam up a stream? I am not saying this is a hoax, people mistakenly attribute intent to things all the time without justification but not to intentionally mislead. I'm not sure why you brought this up but dimetrodon was a synapsid like you and me, triceratops and every other dinosaur were diapsids like crocodiles, lizards and birds.
  2. I've never read that, do you have a citation? Triceratops was large enough to down trees like an elephant of today and it's not unreasonable to think they may have done that but the idea of dam building by an animal with such a small brain and the mental capacity that is thought to go along with that small brain would make such long range planning unlikely IMHO. Has there ever been any evidence to suggest dam building among dinosaurs? I think "may have" is the key in this sentence.
  3. Watch out for the ones with fuzzy butts!
  4. A nuclear bomb, currently that would be a max of around 3 megatons if an asteroid like Apophis his it would be around 1000 megatons. https://www.planetary.org/articles/will-apophis-hit-earth What would happen if Apophis hit Earth? Apophis would cause widespread destruction up to several hundred of kilometers from its impact site. The energy released would be equal more than 1,000 megatons of TNT, or tens to hundreds of nuclear weapons. BTW a pop up ad just wiped out what I was writing in response to this post.
  5. It would depend on the size of the initial object but the transfer of energy to the atmosphere from a large object would be devastating even if dispersed.
  6. Dispersal could be a double edged sword, the asteroid represents a huge amount of kinetic energy, even dispersed the fragments would transfer the same amount of energy to the Earth as the solid object. Changing the objects orbit so it doesn't hit at all would be the best outcome, IMHO.
  7. It's interesting that there exists an asteroid with a ring,I wonder if a strike from a solid asteroid on a rubble pile asteroid gives some validity to to your idea?
  8. I provided a link that explains why we can't see asteroids coming in from the glare of the sun.

  10. I'm on an older chrome book and the ads are off the hook!
  11. Good point but isn't every other existential threat the same> Shouldn't we prepare for this one?
  12. As long as we don't get a large asteroid approaching from the direction of the sun... We are fine only because it hasn't happened... yet
  13. To tell the honest truth IMHO, whatever we do, our only real hope is to plan ahead, this discussion should be taking place way before now and action should already be in place. I know others have discussed this but here we are with nothing to protect us... action is needed. I think the current worry is over Apophis, some 300 meters across? Imagine the cluster fuck if it was found that this asteroid was going to hit instead of passing us by in a few years, could we do anything even with such a long warning time? The time to have started this was 20 years ago, anything we do will require years of lead up time, prototyping, testing, not to mention getting international laws bypassed. This should be a major worry for everyone. A side note, if we could, wouldn't be better to direct an asteroid into the Moon or another body, just to make sure it doesn't come back around in a thousand years or so, or would this just open another can of worms?
  14. On the face of it this would seem to be the best if not the fastest way to go in this endeavor. The basic idea behind deflecting an asteroid being conveying energy to the asteroid in a controlled manner?
  15. Interesting for sure, if the distance is too much to over come from Earth orbit why couldn't the laser be moved closer to the target? If the laser is going to be in orbit anyway and if time permits just move the laser closer? I'm not sure how big the space craft containing the laser would have to be but I would assume it could be built ahead of time and stored in orbit until it was needed?
  16. To be honest I am going by a report I watched on YouTube, I agree that the current version of the report contains considerable info related many years after the sighting. But the initial reports are provocative if not confirmable. This is of course a problem with many sightings of years ago. Initial reports are rehashed ad infinitum and are almost certainly added to to some extent. https://en.wikipedia.org/wiki/Westall_UFO The bold part is less than supportive of the popular discriptions now being made. It is so easy to be impressed by the reports of the people if the report is made after years of discussing among the witnesses and that fact is omitted. Current testimony makes it seem like the sighting has to be extraordinary, I should have looked much closer to see when the testimony was given.
  17. Here is an explanation of laser divergence. https://en.wikipedia.org/wiki/Beam_divergence I am math impaired so I am not sure how to use this information but I am sure someone here could.
  18. Of course that ignores the eye witness testimony but your point is well taken.
