why do we still have spiral arms on galaxies?
shouldn't they be gone by now?

scientists agree about every 50yrs a planet blows up(nova,supernonova's)there are less than 300 reminates of nova's,shouldn't we have more?

scientists agree that the moon is getting farther from the earth.which means it used to be closer.
if you brought the moon in closer the inverse square law would come into effect and just from the effect on gravity and the tides life couldn't exist.how do you explain life?
by doing the math it's agreed that the moon and earth would have been in contact about 1.2 million yrs ago.

can anyone answer these question for me?

Due to the tidal forces of weight [gravity] and the tangential component [vortex force] two parts, vortex force to the moon is of increasing angular momentum away from the Earth, this process of angular momentum conservation, therefore slowing down the Earth's rotation cycle. In recent years, some countries in the world after scientists and technical workers in-depth observation and research, found that the moon is gradually away from us, and will be increasingly dark. The United States and France scientists use astronauts landing on the moon in 1969 when the United States placed in the mirror on the moon to measure the results showed that in 28years to the distance between the Earth and the moon increased 1 m, The United States and France the two scientists is the use of accurate time measurement to measurement, the distance between the change, This method of pulsed laser projection, and then to the mirror reflection back on the ground detector, a return of about 2.5 seconds, Constantly measuring return by the time the changes on the distance that can change. Repeated measurements show that the earth and the moon because of the distance between the earth's surface tidal friction role annual increase of nearly 4 cm. Scientists believe the moon and under the influence of the Earth's gravitational tides produced, this tidal movement on the part of decentralized energy to the Earth's oceans, As a result of this energy - the loss of the campaign on the Moon system be affected, and this is moving away from the Earth's moon reasons. United States 2 geographers through Nautiloid Fossil study also found that the moon is moving away from Earth indeed. The two scientists observed several Nautilus existing fossil study found shellfish on the tree-ring wavy thread with the same performance, Thread at many points, though different width, but on every small wavy line growth in the 30 or so with the modern Lunar exactly the same as the number of days a month. Observed that the Nautilus, wavy lines of a long day, following a month long. Growth in this special two scientists to be greatly inspired, they observed the Nautilus ancient fossils surprised to find that the growth of every parrot the lines traced with the fossil's diminishing. And the age of the same line of Nautilus shell growth has to be fixed. Research shows that the modern Nautilus shell, the growth line is 30, the new generation of Oligocene Nautilus shell , the growth line is 26, Cretaceous Mesozoic is 22, 18 is Jurassic, Paleozoic Carboniferous is 15, Ordovician is nine, Concluded that 420 million years ago before the Ordovician, Paleozoic, and the moon around the Earth only nine days a week. Two geographers According to the Law of Universal Gravitation, such as physics theory, the moon and then calculated the distance between the Earth, Get a result, more than 400 million years ago, the Moon and the distance between the Earth is now only 43%. Scientists have also nearly 3000 to a record of pitting corrosion phenomenon on the calculation, of the findings fully consistent with the reasoning that the moon is gradually away from us.
using gravitational& vortex force the formula to calculate the moon from Earth:
Cos а ≈ 1
Me = 6 × 10 ^ 24kg; month - the distance r = 38.4 × 10 ^ 7M
Mgh = mv^2 / 2 ①
V = at ②
Moon average week: v-= 1 / π ∫ vsin ω td ω t = 2v / π ③
Angular velocity difference: q = 29/30 = 1-1/30
V-= 2at / π; ω = 1 / T
a = KGM ω/ r ^ 2 ④
Mg = GMm / r ^ 2 ⑤
111Daily the moon away from us: h = 2GK ^ 2Mq / π ^2 r ^ 2
= 2 × 6.67 × 10^-11 × 0.16 × 6 × 10 ^ 24 × 29 / [38.4 × 10 ^ 7] ^ 2 × 3.14 ^ 2× 30
= 8.51 × 10 ^- 5m
From a year: 8.51 × 365 × 10 ^- 5 = 0.031m
This is close the measured value

thanks for that answer
the only numbers that i seen show that earth and moon would been together between 1.2 earliest and 1.8 oldest so i'll do so more research

....or in English....

Each galaxy has 6 billion billion stars. In each star there are two forces at work...one reactive force pushing out and one gravitational pulling in. This process takes a very long time to stop. The reactive process occurs with the hydrogen atoms until they turn to helium, carbon, etc....the star increasingly becoming composed of heavier and heavier atoms. It's a multiphasic process that never just ends abruptly. And that's just one star. We have an "astronomically" huge system at work just in this one galaxy. It contains a great deal of mass and is, itself, part of an even greater system.

This process you're asking about? Don't wait around for it.

The reason the moon's orbit is increasing in size is basically that the earth rotates faster than the moon travels around the earth. The earth, in a sense, pulls the moon along, trying to speed it up to catch up....at the same time, the moon is pulling back on the earth....on it's tidal bulge trying to "slow it down". There is a friction created and in a nutshell, it stretches by a very small amount, the orbit of the moon around the earth. It has almost nothing to do with the burnout of other objects in our galaxy.

The earth's rotation is also slowing down due to this effect....just FYI.

lol very nice summery

Got to love Astronomy....

Here here ! To us! The geeks !

Actually, I'm a bit more into astrology, but to be into one, one must know a bit about the other

thanks but that's not what i was asking.i know most of that.
i was why are the spiral arms still there,why not more nova's and how did life exist

I think you forgot some words in there. I'm not sure what you're asking.

opps my typing sucks
i was asking why do we have spiral arms on the galaxies?
why don't we have more nova's?
how did life exist?

What life? And you don't ask much, do you?

goes to show, you learn something new everyday..

I had always been under the impression that the moon was gradually falling toward the earth.. given gravity and all. I don't recall ever having covered that material in any physics or geology classes but it would just seem intuituve that the moon would eventually fall into the earth..

it could be that it's still "on the way up" from the initial impact billions of years ago and will eventually reach the apex so to speak and begin falling back toward the earth...

that's pure conjecture though, based in no way on actual knowledge or research..

interesting..

I will take a guess at it:

1.)The spiral arms on the galaxies show how the galaxy is spinning as it collapses at its center which is a black hole. (Kind of like water spins as it drains down the sink hole.)

2. Why do you think we should have more Nova's?

3. How did what life exist where? (You must be more specific in your questions.)

Could it be because the universe itself is expanding and all the galaxies are getting further apart?

Just a thought.

Hey 'deke',

What's that question of your's all about???

'... How did life exist? ...'

You've KNOWN the answer for a long time!!!

Have you lost your bible???

Deke there are many hypothesis out there for your questions, what are yours?


Here is what I could find in 5 minutes.
