  1. Assuming the box contains air and dimensions are the inside dimensions and ignoring losses the approximate energy required is... Cv * Mass * temp = energy required 0.718 Kj/Kg-K * .034 kg * 1C = 0.024 kj or 0.00666 Wh unless i made a math error
  2. Yeah, but "A Galaxy Died!" is a way better headline.🙄
  3. I did get a chuckle out of the post. Are reptilian Pleiadians part of this, or is that a different thing?
  4. I don't worry about it. I can't say it won't cause harm because I don't know that. If cell phone use caused 1 cancer per 100,000 then it does cause harm but the risk is acceptable for me.
  5. Yes. Ionizing radiation is certainly dangerous in doses higher than background. X-Ray machine technology continues to decrease the dosage while increasing resolution. It is certainly possible, but the effects would be very small since studies to this point have not shown a clear correlation.
  6. One study finding a possible issue is not very concerning. Work has been ongoing for at least 40 years on the health effects of nonionizing radiation and no clear dangers have been found, so I would not be concerned. However, if everyone who has cell phone starts dropping dead I will withdraw this post...🙂
  7. I hope this guy didn't really waste 20 years on this! On the other hand if it makes him happy it is a rather innocuous hobby.
  8. There are so many variables it is hard to tell. Are you sure the insects are grasshoppers? What species of grasshopper were they? Was exactly the same time as the year before? Was it a different time of day? Was the foliage the same lushness? Was the weather prior to visiting there significantly different than the year before?
  9. No. Only H, He and Li were formed after the big bang. The heavier elements were formed in stars, the heaviest elements were formed in super novas.
  10. Well, having to ask that question is not a good sign... You seem to be over thinking this and confusing yourself. Everything you see happened in the past. Images from your television happened a tiny fraction of a second ago. The image of the moon you see happened about 1 second ago. The image of the sun that you see happened about 8 minutes ago. The image of Alpha Centauri happened about 4.5 years ago. So lets look at this idea of a 'universal now'. In the universal now lets say that the Death Star destroys Alpha Centauri. Well obviously I won't be able to see that rather spectacular explosion from earth because the image of the exploding star will not reach me for another 4.5 years. So I will see that explosion 4.5 years into my future. Here is a simplified scenario just to get the concept: So if we are looking at a galaxy that is say 10 billion light years away, then we are looking at the galaxy as it was 10 billion years ago. That means its brightness, location and shape are all the way it was 10 billion years ago. In the universal now the galaxy is much farther away and probably much different in appearance. The galaxy might be 40 billion light years away in our universal now. So in the universal now, the light leaving that galaxy will not be something I could see until 40 billion years in the future on earth. This next paragraph is an unnecessary complication of the basic concept but is added for completeness. In reality a galaxy that is said 10 billion light years away means that the light from galaxy has been traveling for 10 billion years not that it was actually emitted from the galaxy when it was 10 billion light years away. The light was actually emitted from the galaxy when it was closer than 10 billion light years, lets say 8 billion light years (forgive me but I don't feel like getting the actual number) but since the universe is expanding as the light moves it must travel farther than 8 billion light years. PS don't get confused by years and light years. 10 billion years - time, 10 billion light years - distance. Hope that helps some...
  11. Steel is an alloy of iron, so subjecting steel to heat will not make molten iron, it will make molten steel. Steel melts well above 1000 C so the steel would not melt. Yes, the wind would blow the Sparks through the air.
  12. Do you have a source for this or is this something you heard somewhere? it is difficult to answer questions about how the wind would effect burning steel in an office fire when a piece of steel doesn't burn. You need to formulate a better question.
  13. I would not expect there to be large amounts of molten metal in an office fire, certainly not enough to pour out of a window. Again the whole office fire thing is not important, I assume. What is your question? Is it something about how a stream of molten metal (a specific metal?) will react with the air or water or what exactly
  14. I have ignited a strip of magnesium foil and it didn't have any flashes as it burnt. I looked at couple of you tube videos and I didn't see any flashes. Powders will flash, which is probably due to the uneven amounts of powder the fire front encounters. You talk about office fires, is this related to specific event of scenario? If not it would be best to leave out the office part as it only confuses the situation IMO.
  15. I am not sure what you mean by flashes, could you expound on this?
  16. Oh no, not this guy...
  17. That's the point, if you feel the need to test if it's a dream then it's a dream, no further test required. I have experienced lucid dreaming, I think that is sufficient knowledge on the subject. You haven't discussed neuroscience that I have seen.
  18. If you ask yourself, "Is this a dream?" , then it is a dream, reality check complete. I doubt any sane person mistakes reality for a dream.
  19. Geeze! I complete misread the OP! My bad.
  20. What do mean it is not relevant? That is the crux of the discussion! That is the reason the 2 scenarios are not equivalent.
  21. So again, why do you think there is a difference for the 2 observers? There is no difference in gravitational potential, velocity or acceleration between the observers.
  22. Why do you think that? There is no difference in gravity like on earth and both observers are experiencing the same acceleration.
  23. Is the date of that article 2/11/1902? Any new information?
  24. Yes, obviously as you pump out water the tote weight will decrease, but the instant you turn on the pump the tote weight would increase.
  25. Yeah it probably isn't, sorry for the hijack...
