    No, IMO, the universe is a defined and expanding space. It expands into a dimensionless permittive condition.

    Density of Universe

    To date, the critical density is estimated to be approximately five atoms (of monatomic hydrogen) per cubic metre, whereas the average density of ordinary matter in the Universe is believed to be 0.2–0.25 atoms per cubic metre

    Accelerating expansion Universe

    https://en.m.wikipedia.org/wiki/Accelerating_expansion_of_the_universe

    Current observations allow the possibility of a cosmological model containing a dark energy component with equation of state w < −1. This phantom energy density would become infinite in finite time, causing such a huge gravitational repulsion that the universe would lose all structure and end in a Big Rip. For example, for w = −3/2 and H0 = 70 km·s−1·Mpc−1, the time remaining before the universe ends in this "Big Rip" is 22 billion years.


    Geeez have I got to do everything

    OK

    AV Den Un approx 5 atoms monatomic hydrogen per cubic metre after 13.7 billion years

    Remaining age of Universe

    22 - 13.7 = 8.3 billion years

    There are other theories and evidence against accelerating expansion within the Wiki article

    I'm not going to calculate how many atoms per cubic metre will be present at the end

    In the article it mentions as wavelengths increase they will be absorbed and atoms of solid material will disipate

    In models where dark energy is a cosmological constant, the universe will expand exponentially with time from now on, coming closer and closer to a de Sitter spacetime. This will eventually lead to all evidence for the Big Bang disappearing, as the cosmic microwave background is redshifted to lower intensities and longer wavelengths. Eventually its frequency will be low enough that it will be absorbed by the interstellar medium, and so be screened from any observer within the galaxy. This will occur when the universe is less than 50 times its current age, leading to the end of cosmology as we know it as the distant universe turns dark

    A constantly expanding universe with non-zero cosmological constant has mass density decreasing over time, to an undetermined point when zero matter density is reached. All matter (electrons, protons and neutrons) would ionize and disintegrate, with objects dissipating away

    As this is so far off topic I'll stop here

    Nevertheless, I doubt the heart would have any knowledge of these possible outcomes.

    Did you know a drawing of the heart is based upon a woman's bottom bending over?

    Actually a woman with the perfect bottom need not bend over .

    Hey river. It is great to see you again. I've been looking for you (on the forums.) Did you know rivers flow TO the sea?

    Of course there is a feedback loop. your physical state influences your thoughts and so can your emotional state. Its constantly in communication. If you fall and break a leg, you dont think it will influence your thoughts? As a mundane example, if you eat healthy, you will have a better mental and emotional outlook.

    From River Post 48
    Do you have a citation for the above or is this just your personal opinion?

    What type of field is it?

    How far does it extend from the body?

    What effects does it have on anything external to your body?
