    A layman's guide to the accelerating expansion of space

    I believe that this was in response to my inquiry. Thank you, Marcus for your kind reply and for everything you do for this community. Again, I am not a physicist. I am merely attempting to resolve a logical conflict in my own mind. Briefly, I agree that a richer understanding of expansion...

    A layman's guide to the accelerating expansion of space

    I have a very brief layman's question. Thank you everyone for the lively discussion that is mostly over my head. Q) Based on red-shift, do we know/speculate/theorize that the acceleration of the universe is increasing or decreasing? There are more technical ways to ask this question. Note...

    Help: Explaining Expanding/Accelerating Universe Without Redshift Fallacy

    Preface: I am not a physicist, but I do tend to accept the theories of an expanding and accelerating universe. I am not inquiring to dispute these ideas, but it recently occurred to me that there is an obvious fallacy in the arguments for these ideas as presented in the popular media. I wish to...

    Simple question about fluid pressure (medical injection)

    I haven't heard much on this topic, really, so I'm not basing my inquiry on any preconceived notions about which is better or worse. I am merely trying to understand a physical concept. Clearly, if you shove a given volume of fluid through a smaller hole, the jet generated is going to move...

    The Science Behind Medical IV's and Flow

    Hi Wolf!, I'm a nurse, too. From reading this thread, I think I understand the answer. Think of it this way: Imagine a really long tube extending vertically that contains an entire liter of fluid. Now, imagine a shorter tube (same diameter) extending vertically that contains only 100mL of...

    Simple question about fluid pressure (medical injection)

    Hello, and thank you kindly for considering my question. Background: Medical needles come in gauges such that a smaller gauge represents a larger needle. Scenario: Doctor Jack says "18 gauge needles are best for this procedure", but Doctor Jane says "27 gauge needles are best because...

    Relativistic Mass thought exercise with approaching bodies

    "Relativistic Mass" thought exercise with approaching bodies I understand that the concept of 'relativistic mass' is somewhat controversial, but for reasons that are unclear to me. Nevertheless, I humbly pose the following thought exercise/inquiry: For starters, I understand the formula for...
