  1. The Schumacher-Levy -9 comet (if that's what it was called?) hit jupiter so hard that it made the core 'ring' apparently!

    Because the turtle will have a slower heartbeat / slower metabolism - so it will take longer for it to reach its 1 billion heartbeats.
  3. Aren't some of the gas giants moons made of ice?
  4. Yea - good point! I must admit when thinking about it further on my way home last night I had the same thought. I doubt it would have gone through both of us.
  5. Apparently astronaughts see them as little white flashes in space - even with their eyes closed. This is because they just go straight through the body - leaving a white flash on the retina as they go through it. Most get deflected before getting to the earth, but I heard somewhere that they can get through to the earth. The grapefruit size may not be that accurate - it was a long time ago and that was how I remembered it. Thanks for your input!

    I read somewhere once it had something to do with a set (or close to) number of heartbeats. An elephant's heart beats very slowly compared to a hampsters which whizzes away. How true this is I am not sure though - could be an urban myth! I'll look it up. OK - on a quick search it seems that mamals live for (very appox.) about 1 billion heartbeats. I'm not sure this counts for EVERY animal, but it is a rough guide for some from what I could tell (don't have time to look it up properly right now).

    Dissolving rate

    It could be that the bubbles in the liquid settle on the tablet? Thus there is less surface area of the tablet actually in contact with water. That coupled with your suggestion that the water is diluted by the disolved gasses sounds reasonable. This is just a guess however and I do not actually know.
  8. I see what your saying - because I was in a 'strange' enviroment (a room I was not used to sleeping in) I could have seen a flash from outside reflected off something. I do however believe we would have seen it with our eyes closed even. It was that kind of intense 'electrical' (for want of a better word) type flash, like mini, instantanious ball lightening. Also it seemed to come out of thin air - not from a surface.
  9. About 10-15 years ago we had a family holiday. My father and I were lying in a dark room in 2 seperate single beds talking about the day. Just as we said goodnight, there was an intensely bright white/silver flash that started at a point just off centre from the middle of the room and grow to the size of grapefruit. It dissapeared instantly (the whole thing lasted but a split second). We BOTH saw this and my dad was amazed and said "what the hell was that" We did not know. Could this have been a cosmic ray? Do they reach us here on earth? Has anyone else seen anything like this? Interested in your views.

    Yea Klanos! but just look at the picture again more closely!.... it's certain proof that a man went to mars and had a sit down! I'm mean.... you just can't dispute that sort of evidence!

    I wonder what conclusions he'd draw from my mates carpet?

    Mars Express Images

    I must admit that I like the pictures. However, when I stare lathargically into my mates beer and coke stained carpet, I see faces/images all the time! As it has been said already - the human brain looks for these sorts of patterns in anything.
  13. It's probably just aliens scanning the earth for intellegent life.
  14. What is the normal sort of size of ice shelf break up during the anual spring thaw?? It'd be interesting to find out - as JohnB said - this does happen all the time, every year during the spring thaw.
  15. If you can work out the force on the object from the air pressure then you are away. You can use F=Ma to get accelaration. Then use the standard equations of motion to work out velocities, distances etc.. Type "equations of motion" into google.
  16. Norway in the north will be way below zero! Being honest - I do not know about Botswana - it's very hot in the day but I do believe it gets very cold in the African deserts at night, so I don't know about this one, I would guess that it's abouve freezing though. (?).
  17. OK - Clear sky then. Ground level summer in Botswanna compared to Winter in Northern Norway?
  18. I always say it TRAVELS as a wave and HITS as a particle - which it does.
  19. Sorry if I'm being dim here, but, Isn't this like asking how long is a bit of string? The answer will depend on altitude, global position, weather conditions, summer or winter etc....??

    Taser.

    There is an old saying " Volts for Jolts, mils for kills" meaning high voltage shocks but just a few miliamps can kill.
  21. Surley GREED is on the list anyway - so not new, just phrased differently. wrt the drugs - long long ago this was seen as sorcery (outlawed in those times) as people who went onto 'magical' trances (drug induced obviously). So still not new - just new terminology - the 'sin' is just the same.
  22. Being fair - thats only the old testiment, which was superseeded by the new - which preaches repentance and forgiveness rather than the stoning and burning. Oh and we can eat pretty much anything now. But I still hate black pudding.
  23. :doh:It actually says in the bible (right at the end) - "DO NOT ADD OR CHANGE ANYTHING IN THIS BOOK" IIRC. Idiots.

    caterpillars

    I have read about Worms and Rats actually inheriting memory from their ancestors that learnt mazes. Offspring of rats which had previously learnt a maze with food at the end of it apparently learnt the maze quicker than those whose parents had never seen the maze. However I think that this work may have been discredited and maybe proved false - I'll have to try and find some refferences rather than using my memory.. i think some groups even took things a bit too far and mushed up some rats that had run a maze and then fed them to other rats. Supposedly the rats that eat the rats that had already run the maze learnt the maze quicker. Again - could be BS though - I've never seen any properly published work - just web chat. I'll have a search arround when I get more time.
