Urgent. School project, need help.

I see what you are saying...

They only reason we use light-years is because we have a limited understanding of the universe in a whole and we needed to make some sort of measurement in order to understand, based on principles like what you said... speed and years...

Yes, you are entirely correct saying that it is based on our solar system, and maybe a more advanced civilization than this ones would have a better and more exact answer than what I can give. Though, like I said... you are correct in your assumption.

Also, did you know that time is actually flowing slower in space, which they believe is a product of gravity and MAYBE magnetism (I'm putting that in personally because we don't understand magnetism fully yet)... If you don't believe me look it up... specifically the atomic clocks.

I will say this... what are you going to use in order to distinguish how far and how fast something went?

What would be better is to do it on a galaxy size scale. Basically ask the question...

If light originated from the center of the milky way galaxy (where the supermassive black hole is), figure out how many times light would travel from the edge of our galaxy and back to the supermassive black hole... you would then determine where lets say 100,000 stars are and determine how many times light would travel back and forth (from edge to center) to let those 100,000 stars make ONE revolution around the supermassive black hole (around the galaxy). Man is that easier said than done though!!! Does that make sense... I tried to make it as simple as possible...

I will check back tomorrow sometime to see if you need anymore help... OR if you have any questions...

Keep up the great thinking! You will do amazing in school, especially physics if you stay with this questionable attitude : )

I think they don't know and the bull shit that is taught is acceptable among ignorant suckers...just my five scents.Cheers

can you re-phrase your questions as a plumbing problem??

GLP is REALLY GOOD at solving plumbing problems!!!

A light second?

[link to en.wikipedia.org]

Well you must be making a point to question reality..

I will refer you to the bible

2Peter3.8 But, beloved, be not ignorant of this one thing, that one day is with the LORD as a thousand years, and a thousand years as one day.

So in the heavens....time is DE-accelerated !!!

one day is always evening and the morning or moonlight and sunlight...one day

Good Luck with that !!!

Thanks very informative.

I run into a brick wall when I try and think about why time is considered so absolute when it is all based on our planets rotation around our sun. I mean everything we know about time is all based on our solar system. 1 day, 24 hours, 60 mins, 60 secs. Then we use these measurements to establish distances. A mile on earth is just...a mile on earth, right? So when we say light travels at xxx miles per second...those miles are earth miles, right?

I understand the relevance when speaking about it on earth, obviously that is how we understand it.

Time is relative... and yes they are earth miles.

Now I want to give you a piece of advice, please think for yourself when given information in school. Think critically and outside the box...

I love you..

Know what? That all of the science that I was taught in school isn't correct...

The standard model (taught in schools), and this model other model that well... lets just say is not going to be widely accepted... Basically think of the earth... then remove the core of the earth and put the universe inside of that... then if you think about why gravity is pushing down it is because we are in a hollow sphere and the rotation of a massive object in the middle (the "universe") is making the gravity push us and keep us to the top of the inner circle of the sphere, basically our feet are up and our heads are down... the ONLY reason I am doing this is because I haven't been to space myself and I don't like to just blindly believe what has been told to me... I will see what these experiments provide... also this seems like it is a universal matrix produced from light... heck if the standard model for an atom is correct then the electrons in the electron cloud ARE light producing something because it is being observed (quantum physics)... I have many thought processes to how the universe actually works, I will not just simply believe because I am told to, I believe because I want to... and I believe that I truly no nothing anyway, so why put a definitive on something I can only speculate about! Until I have 100% proof on something, I will keep speculating...

No, no, no, you've misunderstood it completely!

As it happens, information travels at a fixed velocity in this Universe. We call that velocity "the speed of light", because light is actually nothing other than information exchange.

What is this velocity then?

It is exactly 1 unit of length traveled every 1 unit of time. Because length and time are in actuality nothing other than byproducts of the spread of information.

So, given natural and proper units, the speed of light is 1. No more, no less. It is 1 per definition! Because a unit of length is the distance that information will spread in a unit of time.

But we don't use the units that are natural and proper to this Universe in our daily life, we use our own "homemade" units that are based on nothing relevant to the working of the Universe. And when you convert the natural units of the Universe to our wonky units, you get strange numbers.

So, we say the speed of light is 299 792 458 m/s. The ridiculous number comes from the fact we are using ridiculous units for length and time. Both the meter and the second are based on particularities of the Earth, and neither is Universal.

But the speed of light is Universal, it is only our numerical measure of it that is local.

Capisce?

ya I understand what you are saying. As good of any explanation as you could want!

Pi

Thinking about it Pi would be universal.

The problem would be that the "distance" and "circumference" would be the variables. The speed of light would be a constant (for argument's sake, I know it's not exactly a constant). You could set up the math problem but you could never solve for it absolutely.

To solve for it you'd have to use some agreed upon universal measure.

No, wait. If you made the distance and speed problem based on a circle with the circumference and diameter set in local (Earth) measurements then anyone with no knowledge of our measures could reverse the problem to see the answer. I'm so terrible at math I don't know how to set it up understandably.

You have 2 points on a circle. You make those points straight across the circle so you get the diameter. That's you distance in your local measure. You somehow take your understanding of the distance and the speed of light and figure it out with the ratio of diameter and circumference. Your answer is then wrapped up in a mathematical constant. Then when some alien race sees your measurements they can work the problem backwards and see your understanding of distance, then convert to theirs.

I don't know how to put our understanding of "time" into the problem. I think you could universally describe the distance in a way that the universe could understand but not how long it would take.... hmm, maybe with known half lives of known radioactive materials and instead of putting it in Earth years a half life is simply denoted as 1.

In any event a good mind game with no real solution.

I love you, you know that?

Einstein once had a theory about space.

It was about time, too!

Ba-dum-ching!

Can you please state your question in a more universal language?

Why is it you think people should speak and write and understand english?

I call bunk...

Lol...

Peace,
