    Graduate Could Multiple Big Bangs and Dark Energy Explain the Expanding Universe?

    I can't help it, I am not going to look up the numbers or do any sourcing here but some of the approximations appear wrong. As I remember the theory goes... In the beginning all 4 forces (gravity, electromagnetism, weak nuclear, strong nuclear) were unified in a primordial atom of infinite heat...

    Graduate Need help with a thought experiment about point of view,motion, and gravity.

    I appreciate the advice mfb. I do understand Newtonian physics and some GR with bits of SR thrown in and can derive the some of the equations(sadly just for fun). The purpose of the thought experiment was the physical mechanics involved. I will keep any personal speculation to myself but I will...

    Graduate Need help with a thought experiment about point of view,motion, and gravity.

    Thanks for the help. Although it doesn't answer all my questions it at least shows me that my reasoning was somewhat sound.:approve:

    Graduate Need help with a thought experiment about point of view,motion, and gravity.

    I agree completely with your statement and it almost argues my point( except where the moons acceleration being greater than the Earth's but I know what you meant). Its completely in line with spacetime as Einstein described it. Assuming the degree of curvature to be relative to the mass of the...

    Graduate Need help with a thought experiment about point of view,motion, and gravity.

    What I am getting at isn't coming through clearly. According to our position in the solar system, were moving (as a planet) at roughly 18 miles a second. We have a lot of kinetic energy as momentum, but only from a reference point. Erasing these reference points and examining the Earth and moon...

    Graduate Need help with a thought experiment about point of view,motion, and gravity.

    Ive been thinking about orbits. We have plenty of points of reference(stars) that help us determine our orientation within the milky way ect. So we can effectively determine orbital paths, rotation, ect. So I've been thinking about the Earth and the moons orbital interaction independently of any...

    Is There a Clear Line Between Scientific Hypothesis and Mere Speculation?

    But what if the way it could be tested exists but cannot be tested simply for a lack of capital? Should that exclude someone from drawing conclusions based on existing data? For that matter the scientific method could be said to be out-dated with the introduction of the internet(access to...

    Undergrad Soot Mystery: Uncovering the Puzzling Phenomenon in a Wood-Burning Stove Room

    Sorry Sophie, I was just trying to expand on your intial thoughts with a few additional factors that may better explain the process and still keep it comprehensible. I am still new to the forum and don't quite have a mastery of its general features, like the quote button I plainly see today but...

    Undergrad Soot Mystery: Uncovering the Puzzling Phenomenon in a Wood-Burning Stove Room

    Does the wall facing the house suffer the same soot lines? I am assuming the outside wall of the house that the porch is attached to in the porch room was not significantly reconstructed when the room was converted. I wouldnt. This means that the porch room is probably insulated from the rest of...

    Undergrad Soot Mystery: Uncovering the Puzzling Phenomenon in a Wood-Burning Stove Room

    Ok, the stove is only lit in cold weather. I am assuming that the porch room does not have a connection to the household heating system. Assuming these, I feel safe saying that the studs, drywall, air behind the walls, furniture ect... Have all reached thermal equalibrium as a system. Lighting a...

    Undergrad Soot Mystery: Uncovering the Puzzling Phenomenon in a Wood-Burning Stove Room

    I do like mrspeedybob's approach to it, although I don't think its applicable in this situation.

    Graduate Why the black hole density is called the infinite density.

    OK, so a black hole forms when the gravity of a set amount of mass has expelled enough energy that it can no longer support itself. When it collapses it forms a singularity. The singularity is infinitely dense and infinetly small. How did a set amount of mass form something infinite? The...

    High School Light bulb uses current or resistance?

    I would caution against spending to much time on the filament, a filament can be made of many different materials with individual properties. The important thing is to understand the basic mechanics of the equations and the definitions. The assumption of more light is taken because more work is...

    High School Light bulb uses current or resistance?

    I=V/R (I) is the current measured in amperes, (V) is the voltage, and (R) is your resistance. Notice the change in amperage. When you plug your numbers into the above equation you can see that when solved for R, you get the listed resistances. R=V/I Bulb A(120W) R=120/1 R=120 and...

    Graduate Understanding the Momentum of Light in Space

    Lorentz transformation is what I think your looking for.
