How fast is the earth moving?

Consider the movement of the earth's surface with respect to the planet's center. The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second-or roughly 1,000 miles per hour. As schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour. In addition, our solar system--Earth and all-whirls around the center of our galaxy at some 220 kilometers per second, or 490,000 miles per hour. As we consider increasingly large size scales, the speeds involved become absolutely huge!

Well, I don’t know. You could jump off with a stopwatch and time it till I come around again:)

Not fast enough. January 20th, 2017, just get here already!

Here’s to hoping that Hillary’s world comes to a screeching halt very soon

Nice video. Jaguars recently have had a reputation of being a handfull near the limits. I have been looking at cars lately. Eliminated any of the Maseratis since none are nearly as fast 0-60 as my 2013 Audi S6 (3.7 sec). I have been looking at the Mercedes AMG-GTS, Porsche 911 Turbo and McLaren 570S. Have not had any hands on with the McLaren, but like it alot. That new Ferrari 488 GTB looks interesting, but have not seen price yet.

Just a few months ago I was out in the backyard and I jumped up to pick an apple off the tree, and when I came down I was in Indiana.

EXACTLY!!!!!!!!!!!!!!!!!!

the Great Attractor which is pulling the Milky Way and all else towards it at the terrific speed of 14 million mph.

After unknown amount of years traveling at 14 million MPH, one would think that by now we'd be getting closer to the source of attraction causing the pull to be stronger and increase the speed of travel and SPLAT!

[MtnClimber]

The sun will go supernova and cook all the planets in about 4 billion years. The Andromeda galexy will collide with our Milky Way galexy also in about 4 billion years. The collision with the Great Attractor is farther out than that so why worry?

I should have said that the cause of CBR is a theory.

Maybe you should have said it, but you didn't, did you?

You missed your chance.

Wow, are you my wife? That is how she talks to me. Don’t try to boink me, I have a CCW and always carry. I don’t know what is wrong with you, but you really stink! Please don’t contact me again. And stop drinking.

The Earth, while spinning (rotating) is traveling “sideways” as it revolves (orbits) around the Sun. Our axis is slightly tilted in relation to the plane of our orbit (hence, the seasons). Our axis always points, just about, to the North Star, Polaris. Of course there are many bodies in our solar system each with its own rather fixed path. But our solar system, with all its moving parts, is headed toward where Leo currently is (because our solar system supposedly is circling the Milky Way which itself is moving towards where Leo currently is). We can say our solar system is “circling” the Milky Way Galaxy because they tell us that we are on an outer edge of the Galaxy and that the Galaxy is spinning. But, the Andromeda Galaxy is in the path of the direction we are moving, so we will collide with it before we reach whatever will be in the direction of where Leo currently is.

And all of this is undetectable by the average couch potato. ;-)

But there is so much space between stars that spiral galaxies colliding have different planar momentums and become giant eliptical galaxies. These have no spiral shapes, but become football shaped with no regular orbital pattern. One would expect head-on collisions of stars with the random orbits which could be in opposite directions resulting in tremendous collisions.

If anyone had gone up to the lobby outside the Blue Room, he would have found something other than fear that barred his way-an almost physical resistance. If he had succeeded in forcing his way forward against it, he would have come into a region of tingling sounds that were clearly not voices though they had articulation: and if the passage were quite dark he would probably have seen a faint light, not like fire or moon, under the Director's door. I do not think he could have reached the door itself unbidden. Already the whole house would have seemed to him to be tilting and plunging like a ship in a Bay of Biscay gale. He would have been horribly compelled to feel this earth not as the base of the universe but as a ball spinning and rolling onwards, both at delirious speed, and not through emptiness but through some densely inhabited and intricately structured medium. He would have known sensuously, until his outraged senses forsook him, that the visitants in that room were in it not because they were at rest but because they glanced and wheeled through the packed reality of heaven (which men call empty space) to keep their beams upon this spot of the moving earth's hide. -- C.S.

All nice toys and all way outside this working person’s pocketbook.

A 2016 Tacoma is enough. Besides I’d probably get killed in anything built for real speed.

[trebb]

Just the right speed - as God intended.

The collision with the Great Attractor is farther out than that so why worry?

You're right. One SPLAT is just as good or bad as another, depending on how you look at it..........

Yesterday is tomorrow..

Hope I’m not alive to see it ;^)
