Jon the frog Posted December 14, 2018 #2 Share Posted December 14, 2018 (edited) And whales ? Megalodon can stay deep and whales need to breath... whale became that big after the demise of large animals? Maybe water doesn't shield cosmic ray at all... cool idea still.

AllPossible Posted December 14, 2018 #3 Share Posted December 14, 2018 Incredible that a star light years away could cause the cancer rate to skyrocket.. I've heard gamma ray bursts could be thousands of light years away and melt our planet if were in the path... 1 Link to comment Share on other sites More sharing options...

Betelgeuse isn't 2 million times the mass of the Sun, more likely about 20 times (So you are slightly off ), its estimated to go supernova "within the next million years" and it is unlikely that it will be powerfull enough to do any damage, merely a spectacular lightshow. I don't think you need to be highly alarmed about Betelguese. 2 Link to comment Share on other sites More sharing options...

I don't think you need to be highly alarmed about Betelguese. Why do people post replies here telling others they are wrong without even checking the facts? Here is a link to some information on Betelgeuse https://www.reference.com/science/hot-betelgeuse-compared-sun-efc0d976d8b621cb It says Betelgeuse is 600 million miles wide which is 965 million kilometres. Just to put that into perspective Jupiter is 800 million kilometres away from our sun so if it was switched with Betelgeuse Jupiter would be swallowed up. That is an absolutely humongous star. In fact the you can see Betelgeuse outside with your naked eye (its one of the stars in the Orion Constellation) and the reason why you can see it despite it being an estimated 600-1000 light years away is because of its absolutely humongous size. It is one of the largest stars in the universe. 2 Link to comment Share on other sites More sharing options...

L.A.T.1961 Posted December 14, 2018 #11 Share Posted December 14, 2018 Minimum safe distance from a SN is thought to be 50 - 100 Light years. If they are further away than that effects would be limited on Earth. So a SN that caused an extinction would have to be within this range. It should not be too difficult to find the smoking gun if true? https://earthsky.org/astronomy-essentials/supernove-distance Link to comment Share on other sites More sharing options...

It is one of the largest stars in the universe. Maybe you should read what I responded to before you get all upset about it ? You said the mass of Betelgeuse was 2 million times the Sun. What you are refering to here is the physical size of the Sun. Those are two different things aren't they ? Btw your link says nothing about the mass of Betelguese. The reason why a star can be 2 million times larger than the Sun and yet "only" 20 times as massive is because red super giant stars are much less dense than yellow dwarfs like our Sun. Betelguese is massive in size, but very low in density, except for the core. The most massive star we know about is about 315 times the mass of the Sun, not anywhere near 2 million. https://en.wikipedia.org/wiki/Betelgeuse https://en.wikipedia.org/wiki/Red_supergiant_star So either you know little of the subject or you meant size instead of mass. If it is the latter why not just say you made mistake instead of attacking me for responding to what you actually wrote? If it is the former I suggest you do a little research before commenting.

Ell Posted December 15, 2018 #19 Share Posted December 15, 2018 The Pliocene-Pleistocene Boundary By Richard Foster Flint Doi: https://doi.org/10.1130/SPE84-p497 Published: January 01, 1965 Quote In natural exposures and drill cores from rocks and oceanic sediments at several localities throughout the world, the Pliocene-Pleistocene boundary is based on evidence of climatic cooling followed by conspicuous fluctuation. The data consist mainly of marine-invertebrate fossil faunas, oxygen-isotope thermometry ratios, and terrestrial plant remains. At most localities there is evidence for transition from warmer to cooler climate rather than an abrupt break. Maybe the amount of heat produced by either the Sun or Earth was affected by an effect of a star going supernova. Or maybe not. In my opinion, though, the extinction event was a direct consequence of cold, not of a higher incidence of cancer - which latter I consider to be a ridiculous idea.

RoofGardener Posted December 15, 2018 #20 Share Posted December 15, 2018 Hmm.... I'm really not convinced. A radiation blast of that magnitude would have had a devastating effect on land mammals... and possibly even plants. There would have been many other signs of such a catastrophe. But - so far as I am aware - no such signs have been detected ? Link to comment Share on other sites More sharing options...
Seti42 Posted December 15, 2018 #21 Share Posted December 15, 2018 (edited) Interesting. I'd never thought that larger creatures would be more susceptible to radiation...But it makes sense now that I think about it. It also makes cheesy 50's and 60's sci-fi where radiation makes things bigger even more ironic and funny.

cyclopes500 Posted December 16, 2018 #22 Share Posted December 16, 2018 Its a double edged sword. On one side you've got the cancer causing effects. On the other it also causes mutations which are the driving force of evolution. Even more when a mutant retro virus gets jammed in egg and sperm DNA. Also where that virus came from there are others. Billions of them all being sniffed up by the same spieces of animals. They all get trapped in the right place in their dna and in one breeding season a new species is born. One with enough genetic variation from the different parents already to boost its survival chances. Link to comment Share on other sites More sharing options...

Sameerr Posted December 28, 2018 #24 Share Posted December 28, 2018 And for that film 'The Meg', i didn't really much felt like seeing a Megalodon movie. Jason Statham is a good hero but the movie didn't seemed much interesting. It's a known thing that in movies, the large animals gets exaggerated. The Megalodon is 75 ft in the film and perhaps they killed 2 big megalodon easily made me lose some interest and i thought the music which played after the movie ended was not suitable for a thriller movie. I think someone should make a good movie or documentary for Megalodon.I would say that the film about white sperm whale,"In the heart of the sea" is better than 'The Meg'.
