I have read and studied this stuff for years and years. Hawking and Feynman are prominent in my library. After all that study I've concluded that my ape brain isn't able to grasp the reality of it. So I peer through my telescopes in awe of it all and I am grateful for never having lost my ability to just observe and say "wow".

Hear, hear, flatty!
I consider the greatest gift ever having been given me is the gift of appreciation. |
She's been a great presence online for years - but this is deeper stuff. Very enjoyable...
"Modern Physics" brought me the worst experience of my 7 or 8 university years. Relativity and the whole time/distance thing blew my mind and I still don't understand it. I'd like to think that I'm a sharp crayon but, wow, I got 18% on that test. Things looked up when we got to solid-state stuff. Fermi I got, Einstein I don't... |
I reduce everything to magnets. It’s all magnets. The answer is always magnets. That weird feeling of repulsion when pressing two magnets together has been the most baffling sensation, well second most baffling sensation, so far in my life.

With regard to the discussion of particles I'd like an answer, in laymans terms to this question. When a researcher declares that a new particle has been discovered how do they eliminate the possibility that it's simply a fragment of another particle?
When you see those images from CERN there are many traces caused by bits and pieces. The curvy traces are particles carrying a charges, the straight lines are described as non charged particles. So the non charged particles may be fragments, but might not they be neutral whole particles? I gots questions. |

https://www.quantumdiaries.org/wp-co..._-1024x768.jpg another way to look at them is this, Quarks are what make up the Nucleus of matter and are confined to the nucleus by the Strong force, Leptons are found in the atoms shells when electrically bound and zip around freely otherwise, again the Bosons or force carriers are on the right and the Higgs providing Mass in the middle, again everyday stuff is the far left column https://cds.cern.ch/images/OPEN-PHO-...ile?size=large |
Interesting contribution on this just published: 94% of all galaxies in the visible universe unreachable. .. unless one can travel faster than light... very well written article with great diagrams...

The closest Star to us...Proxima Centauri... The Voyager 1 spacecraft is on an interstellar mission. It is traveling away from the Sun at a rate of 17.3 km/s. If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive! |
Eric, do you really believe that humans are evolving?
What I see is knowledge is being passed down and not having to be gained anew. Our knowledge is evolving. But humans? What is our DNA doing? |

Some how I missed the evolutionary train on that looking at a cellphone thing.
I had one of the early smart phones pre Iphone. When the Iphone came out it was too much $$$ for my youngself to afford to keep up and meet my life goals. Then eventually I observed the way people with Iphones changed. And went, nop, nop, domed. Not the same for everyone, some make great business use out of them. Quote:

its just a plot to get more property tax out of us as our property expands.

3.2 million years ago our ancestors were like Lucy. https://en.wikipedia.org/wiki/Lucy_(Australopithecus) 1.2 million years later the first Homo erectus evolved from the ancestors like Lucy. https://en.wikipedia.org/wiki/Homo_erectus |

The TV show I mentioned above was exploring this subject as it relates to finding other life or other life finding us. |
I just can't imagine a universe without life on other planets. It is just so far to the next star and unimaginable distances to the next galaxy that I can't image we will ever be able to communicate with them, much less have a visit from them, or travel there.
I know all the old saws, about how people all believed that traveling faster than 35 MPH was impossible when the horse was the fastest mode of travel. Unless Einstein's theories are finally proven wrong, it just can't happen. Everything keeps proving Einstein was right. There was no math or testing the theory abut faster than a horse travel was impossible, just like thinking going to the moon was just impossible. I honestly hope to live long enough to discover life on Mars, but I doubt I will live long enough to ever know if there is life in other solar systems. |
