Big-Bang and Beyond
Ever since I was old enough to spell "science", I have carefully evaluated many of the world's most unbelievable proposals in theoretical-physics, including Einstein's. The only time I slammed into the brick-wall of disbelief was at the mention of singularities. There's no such thing as a Singularity, or to state it in terms of a quote I might be remembered for, "A Singularity is the detectable part of a cyclical-process that is viewed over too short a time-frame". A significant example of a singularity, in most minds, would be the Big-Bang. Much of my adult-life has been spent seeking a model for the Big-Bang that would fit with this claim regarding singularities.\n\nFor a model to have any credibility at all, it needs to incorporate some containment-mechanism capable of causing the collapse of the current universe. Without this, there could be no traction for the idea that anything might exist outside the current Big-Bang and its end-game [ whatever that might be ].\n\nOne of the unbroken rules of Nature is that nothing exists without a reason. A most fundamental driver in science is the search for these 'reasons'. Without question, the biggest of the unexplained in our observable world are dark-matter and dark-energy. In a sense, this is convenient because it allows the 'darks' to participate in modelling various explanations for other phenomena.\n\nMost models of our universe make an implicit coupling between the few percent of visible universe and the darks. If it was conceivable that the darks were uncoupled, then I could build an almost Newtonian model of the current universe, where the visible part was being dragged outwards. This would satisfy the relatively recent observation that the rate of universe-expansion is increasing. But if, overall, the dark component was actually contracting at the same time, that could provide the essential element that would lead to eventual collapse and the start of the next Big-Bang cycle. \n\nTo take this further, I am going to need a huge amount of support to cobble together a mathematical model where the visible and the darks can actually be decoupled [ this is obviously the non-Newtonian bit ]. The next giant step will be into territory we are forever unable to visit – "What exists outside our current universe?".\n\nI am very willing to accept that time and everything in our physical-world was created at the instant of the Big-Bang. This could be accommodated by a rearrangement of the matter/energy equilibrium [ can't get away from that 'conservation of mass/energy' concept ]. What is much harder to accept is that all the RULES that govern our existence were also crafted in that same instant. These rules are way too beautifully formulated and mind-bogglingly complex to be just a one-off shot at the equations and parameters of creation. There is also a complete absence of evidence that there has been even the minutest change to any of these rules since time began. In any case, the intricate relationships involved would basically preclude any isolated variations, no matter how subtle.\n\nA comfortable explanation [ for me, at least ] is that the Big-Bang cycles occur in a constant background where the 'rules' are steady-state. Sadly, the proof for this hypothesis is quite likely to occur well outside my life-span.\n
Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
We explore the history of blood types and how they are classified to find out what makes the Rh-null type important to science and dangerous for those who live with it.
- Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
- Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
- It's also very dangerous to live with this blood type, as so few people have it.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
