1) Message boards : Science (non-SETI) : The Goldilocks Zone, how large? (Message 1906285) Posted 10 Dec 2017 by David Chappell Post: I have a question about the Goldilocks zone that we inhabit here in space. For example, we are 93,000,000 miles from Sol, so are we in the middle of the zone, at the closest edge or at the farthest edge of the zone? Just how large is this zone? Thanks for any replies.

Not quite, what they have called dark matter is in space and part of it, apparently. But it is expanding and in order to expand you must some something to expand in, since it canâ€™t be Space it must be the Dark Matter. You hear a lot of people ask the question, what is at the end of the Universe? My theory, it is 100% Dark Matter. Our observable universe must be expanding into something, that is logical, but not necessarily dark matter. Grant and I have a bubble universe theory that could answer your questions. I know that there is Dark Matter in what we consider Outer Space, but I think that there is a possibly that this matter somehow got mixed in what we call our Outer Space due to the expansion of the Universe. Iâ€™m just guessing this for I do not have the slightest idea on how it really works. Like I said, not in the slightest way am I a scientist, heck of a video artist, Space just grooves me. Have to look into that bubble theory.

(Message 1517023) Posted 16 May 2014 by David Chappell Post: Lets get back to the basics, measurement of time. 60 seconds =1 minute, 60 minutes=1 hour, 24 hours=1 day, 365 days=1 year. All of this is base on one thing, movement. Movement by the means of the rotation of the Earth and the orbit of the Earth around our sun. In order to have movement you have to have the means to do so, Space. Take away Space and you take away the ability to have the concept of time. As I said earlier the farther point A is from point B the more time you create, subtract the Space, the less time you have. Julie brought up the issue of half-steps, I agree, you can never eliminate Space. A good reference of this is the movie â€œThe incredible Shrinking Manâ€ or the PBS series on String Theory. So do boil this down a bit I would say, no movement, no time, no Space, no time and as I think, once you are in Space our concept of time no longer applies anyway. Now some of you are talking about the Big Bang, the Expansion of the Universe and the speed of light, these are some of my thoughts on this. We have discover that there is something out there other then Space and I think they called it Dark Matter. Supposedly itâ€™s the glue that holds every together. So I think that before the Big Bang this is what there was, 100% Dark Matter, then BANG! The universe is form. But it is expanding and in order to expand you must some something to expand in, since it canâ€™t be Space it must be the Dark Matter. You hear a lot of people ask the question, what is at the end of the Universe? My theory, it is 100% Dark Matter. Keep these posts coming, love to read them AND get educated.

They may appear to run faster or slower depending on the observer's point of view. But to members of the spacecraftâ€™s crew the clocks will appear to run at a normal rateâ€ True, but they will be referencing Earth time. Let me throw A Winkle In Time, I know, bad pun. Lets add space to the mix. Lets say you got point A and point B. Point A is 50ft (15.24m) away from point b. It will take a set time to reach point B from point A, but as you move point b closer to point A it will take less time. When you finally have both points next to each other, puff, no more time. So the more space you have the more time you have and vice versa.

(Message 1508526) Posted 25 Apr 2014 by David Chappell Post: Once again, thanks for all of the insightful comments on this thread, I really enjoy reading them. So it seems that once we leave Earthâ€™s orbit we will need a new way to measure the passage of time. Now if we stayed in communication with Earth and we needed to know how long we have been in space,we could just ask mission control on Earth and they would say that we are three Earth dayâ€™s out, but that would really only apply to Earthâ€™s time. The crew on the spaceship would have no way to measure the passage of time. This is just a lark and maybe a bad joke but remember watching Star Trek, they always give the date, StarDate 176.8 or something like that. I guess we will just have to wait until the first Enterprise Starship is launched to find out just what the hell that means, or when we meet our first Aliens and ask them how they do it. Just a little try at some humor that probably missed.
9) Message boards : Science (non-SETI) : How do you measure time in space? (Message 1498911) Posted 3 Apr 2014 by David Chappell Post: These are some very interesting and nice responses so far. We all know that there are different ways a person measures time relative to the planet that he or she is on and how long it takes to orbit the sun. Lets take Jupiter for a contrast. A year on Jupiter is equal to 11.9 Earth years. A day on Jupiter is equal to 9.8 Earth hours. The Pioneer 10 spacecraft was launch by NASA in March 1972 and passed by Jupiter in Dec. 1973. A total time of 1 year and 9 months Earth time. But say I was living on Jupiter, then it would have taken the P-10 eleven plus years to reach me. Now lets say that I was on the P-10 and my darn watch broke and I couldnâ€™t communicate with Earth or Jupiter. How would I measure the passage of time? Yo mentions pulsars and atomic clocks but how would that work? You have to be able to see a pulsar wonâ€™t you? And an atomic clock must be set to some standard? I know that time is an arbitrary unit of measurement, and I know that Iâ€™m overthinking this. But it does boggle my mind to know that in a thousand years this is going to be a real problem to all of our space faring friends. Ha!
10) Message boards : Science (non-SETI) : How do you measure time in space? (Message 1496991) Posted 29 Mar 2014 by David Chappell Post: I would like to start an intelligent discussion on how one measures time in true space. Going on the assumption that time is measure by orbital movements it would seem that once you left the orbit of Earth time would cease to exist as we know it. Just to let you know, Iâ€™m not a scientist.
