From AI, which largely agrees with you. The numerical value varies with the estimate of the time it takes to orbit our galaxy's central supermassive black hole:we could add the 600,000 mph velocity around the galaxy.
"The Sun travels around the center of the Milky Way galaxy at an average speed of approximately **828,000 kilometers per hour** (or about **514,000 miles per hour**). This orbital speed is often referred to as its "galactic orbital velocity." The Sun is located about **26,000 light-years** from the galactic center and takes approximately **230 million years** to complete one full orbit"
You've probably seen this, which, if one can remember the lyrics, can help one remember these values:
Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second so it's reckoned
The sun that is the source of all our power
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour
In the galaxy we call the Milky Way
Our galaxy itself contains a hundred billion stars
It's a hundred thousand light years side to side
It bulges in the middle, six thousand light years thick
But out by us, it's just a thousand light years wide
We're thirty thousand light years from galactic central point
We go 'round every two hundred million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The lyrics above should say that the earth is rotating (about its axis) at 900 MPH, not revolving, although that value would not be at the equator. Revolving refers to earth's orbit around the sun, which they give as 19 MPS.the earth spins at 1000 MPH
But that's not how we describe rotational speed. It's done in degrees (or radians) per unit time. The earth rotates about its axis 360 deg every 24 hours, and that's true at any latitude, but the 900-1000 MPH number refers to the rotational speed near the equator, which is a circle with a diameter of about 25,000 miles. Somebody standing there will move 25,000 miles in 24 hours, or about 1040 MPH, but at a higher latitude, where the circle traveled is say 12,500 miles, the velocity will be about half that.
The speed in MPS or MPH gets progressively slower as one approaches the poles, but not in degrees per unit time.
That was a response to, "Man existed before he developed writing." Yours is a good example of what I mean by a nonresponsive answer. I have already tried to illustrate this difference to you, but I'll try againYou have no evidence to support your belief there was no fundamental change in humans.
Here are some responsive answers. They may be incorrect, but they address what was written:
- Agreed. I miswrote.
- No, man did not exist before he developed writing. He began to exist that day.
- It all depends on what we mean by "man."
- What time is it?
- I like cheese.
- You have no evidence to support your belief there was no fundamental change in humans.
- John was may favorite Beatle.
That was in response to, "Gods enjoy the same ontological status as vampires and leprechauns" and is also a nonresponsive replyhow were the pyramids built?
Responsive possibilities. Again, maybe wrong, but they indicate that the responder understood what he responded to:
- Agreed. I miswrote.
- No they don't. Vampires and leprechauns are thought to live on earth, and gods live in the sky.
- What's a leprechaun?
- You have no evidence to support your belief there was no fundamental change in humans
- How were the pyramids built?
- I like turtles:
Do you know how that was determined? That was some fascinating science. It alone justified the expense of Hubble mission. So did the deep field long-exposure photos of galaxies in what appeared to be empty space to the naked eye and ground-based telescopes.I like how every believer took the acceleration of the expansion of the universe in stride.
Absolute distances to stars are measured three ways.:
[1] The distance to the closest celestial objects can be judged using parallax as the earth moves through space.
[2] Cepheid variables (regularly pulsating stars) are standard candles, meaning that their absolute magnitude is known by the period of their cycling between brighter and fainter, so we can use their apparent magnitude to judge their distances. This information can help us know how far the galaxy containing one is, but they're relatively faint and can't be seen in the very distant galaxies. If we use just those two means of determining absolute distance and combine them with red shift data, we can determine a rate for universal expansion (Hubble constant), but only for the relatively recent past - the last half of the age of the universe more or less.
[3] The third method utilizes a second standard candle that is much brighter than a Cepheid - a type 1A supernova. Hubble looked much deeper into space and thus into the past than ground-based telescopes had, and harvested data on these. What was discovered using these new standard candles and their apparent brightness coupled with redshift data was that the rate of expansion in the past was slower.
It should be noted that no experimentation was done there. The science is all observational and computational.
You needn't bother. I'm quite adept at elementary probability.how many times have a told you that if you flip a coin a billion times that every outcome is equally likely?
Did you know that that statement is true for any number of coin flips, not just a billion? The proviso is that we are specifying the order of the individual heads and tails and not just their aggregate numbers (permutations rather than combinations).
Each of these permutations of the outcome of four coin flips is as likely as each other:
HHHH
HHHT
HHTH
HHTT
HTHH
HTHT
HTTH
HTTT
THHH
THHT
THTH
THTT
TTHH
TTHT
TTTH
TTTT
Two heads and two tails is more likely than any other combination:
4H = 1 (HHHH)
3H/1T =4 (HHHT, HHTH, HTHH, THHH)
2H/2T = 6 (HHTT, HTHT, HTTH, THHT, THTH, TTHH)
1H/3T = 4 (TTTH, TTHT, THTT, HTTT)
4T =1 (TTTT)
Three of one and one of the other is a commoner combination than two of each or four of one
4/0 = 2 (HHHH, TTTT)
2/2 = 6 (HHTT, HTHT, HTTH, THHT, THTH, TTHH)
3/1 = 8 (HHHT, HHTH, HTHH, THHH, TTTH, TTHT, THTT, HTTT)
These numbers are useful in bridge. You're missing 4 spades that the opponents hold. They'll break 3-1 more often than 2-2 or 4-0, but if we are specifying which opponent has the one, they'll break 2-2 more often than 3-1 with the singleton to your left, for example.
That's not the definition of fitness.You believe in miracles like defining fitness as the cause of gradual change makes it all pop into existence.
I don't know what you're trying to tell me here, but it doesn't seem to relate to anything I've written to you.Every single thing we've learned since the ToB shows us the world is more complex than we had known. We've no dissected atoms into many pieces we don't even understand but we do know that all events start at the subatomic level and there are a finite number outcomes to every occurrence though this number is enormous. But you ignore this and ignore the butterfly that flaps its wings for unknown reasons and then you think you know everything because hurricanes form over warm water and are very windy. I'm astounded at the hubris
Too bad that you don't like plain English. Maybe you're saying that some things are too complex to describe completely or predict accurately. If so, those would have been better words to use.
I also don't know where hubris enters this. Are you referring to my claim that I can predict much of what will happen in my life before it happens - enough to make my life largely stable and predictable? No brag, just fact:
The biblical writers knew nothing of universal expansion and so didn't try to explain it, but if they had, their answer would be that God did it.What supernatural way is in the Bible to explain why the expansion of the universe is accelerating?
Or as you would word it, suddenly. All change is sudden, right?Even a gold nugget will corrode away in tens of thousands of years.
