Gian's Achievements


Meson (3/13)



  1. I found loads of Red Squirrels on the Isle of Wight in the summer, but due to the invasion of Grey Squirrels very few are left on the mainland of Great Britain. Is it theoretocally possible to develop a pharmaceutical contraceptive substance specific to one particular species like the Grey Squirrel, but which would not affect Reds or any other species? We need our Reds back! Cheerz GIAN😊
  2. To everyone who's replied THANKS β€πŸ™‚πŸ™‚
  3. Thanks πŸ™‚ Does her composition give psyche a magnetic field? Thanks πŸ™‚
  4. Do we know many metals are in the outer solar system? eg the gas giants, Pluto, their moons and the Kuiper belt? Or can someone point to some easily intelligible layman's literature. I'm thinking that if human beings were living there, they'd need to mine metals to make their own stuff. Cheerz GIAN πŸ™‚
  5. Theoretical physicists always proclaim portentously that the singularity at the centre of a black hole "is where our laws of nature break down" which sounds to me like another way of saying "we don't know the answer." But as no physical process is ever absolutely instantaneous (I think,) surely the collapsing matter gets smaller and smaller while slowed down by ever increasing density so it never quite gets to the singularity and the process continues to infinity. Eg if you keep dividing 1 by 2 you'll never get to zero. Cheerz GIANπŸ™‚ (I've no science qualifications beyond gcse maths n physics grade C, so pls be gentle with me.)
  6. For vitamin D synthesis, is daylight on an overcast day as effective as direct sunshine? Cheerz GIAN
  7. Thanks for the above replies. Hi Zapatos, with a pulled pork sarnie I could do without chips. But yes you have a really good point. Sci-fi often pictures settlers arriving on new worlds and then starting agriculture to support themselves. But in our solar system, maybe it would be a good idea to start producing food on other planets of the solar system before people get there. And if someone sent a crate of pork chops to Titan, with her surface temperature of -290Β°F, I bet they'd still be edible even if explorers didn't get there for another ten years.
  8. Scientists theorize that there may be a big subterranean ocean of liquid salt water on Europa, and there is a proposal to send a space probe which could drill down to it. In such an ocean there would be presumably no light, and I don't know if there'd be any CO2 or what temperature the water would be, but by introducing autotrophs from our own oceans would it be possible for explorers to start a food chain, gradually introducing higher species culminating in fish? This would permanently give explorers and settlers something to eat, although they'd have to have chips sent up from Earth. Cheerz GIAN πŸ™‚
  9. If microbial life is discovered in Venus' atmosphere, and samples are collected, will science be able to tell us whether its ancestry somehow found its way there from Earth, or whether it's definitely a product of abiogenesis on Venus? Thanks GIAN πŸ™‚
  10. Thanks Swansont. What is 'displacement?' πŸ™‚
  11. Apparently the Orion Project for nuclear powered spaceflight asserted that by this method with an acceleration of 1G an Orion spaceship could attain a speed of 10% of the speed of light (c.) Mathematically, how do I work out 1. the length of time it would take to get from 0 to a speed of c/10 (ship's time,) and 2. what would be the distance travelled in that time? Cheerz GIANπŸ™‚
  12. I picture explorers creating giant igloos to use as greenhouses, with methane-powered heating to room temperature and melting water ice for crops and pasture, and also extracting oxygen from water (electrolysis?) to make breathable air. But yes I suspect there wouldn't be enough 'goodies' on the Titanian surface to grow stuff, so the astronauts would have to bring their own compost. Can you define magnetosphere and explain why it would be a problem for animals please? (I'm a novice at science) Thanks GIAN πŸ™‚
