When I think of dave jones right now hes upside down at a 45' angle below me moving 1000's of miles an hour and I'm about 15,000 miles away.
Is there a site on the internet where you enter your location and it tells you the speed and direction you are moving in relative to the sun? Relative to the stars?

You couldn't possibly be that far away unless you were in space.
You can see from the picture I uploaded that the Earth's radius is around 6378 km, so, less than twice that, unless he'a on the exact opposite spot from where you are on the Earth. So to get there then without going out of your way, you would have to go straight "down under" so to speak.

The further away from the equator you are, the less vertical from the center of mass of the planet you stand, the small force contributed from the planet spinning means we lean a tiny amount towards the equator down here.
Also at any time your relative speed to a person on the surface is close to 0, as you both share the same reference frame, if you did a sub orbital hop, then your house would be moving towards you a fair bit faster than daves house.
From the reference of the sun, then dave moves faster, as it draws a less straight line in the sky, (hyperbolic arc), sadly we are still too far from the poles to see fun stuff like the sun doing loops across a day.
Or if you mean tectonic plates, then i think we may be moving at a breath taking 4-12cm / year. (I dont actually know what plate your on)
Or furthur down there is the shrink and swell as the moon orbits, being closer to the equator would move you up and down a few cm, where we are closer to a few mm.

Did you ever consider how time machines in fiction (of course) somehow put you in the same place, except a few hours, years, centuries forward of backward in time? Despite the fact that the Earth is spinning with the surface moving at anything up to 1600 km/h, the Earth is orbiting the Sun at 108,000 km/h, the Sun is orbiting the Milky Way galaxy at 720,000 km/h, and goodness only knows how fast the galaxy is moving relative to .. I don't even know what.
Truly magical machines.

The web site windy.com allows you to visualize wind vectors in realtime, its great for weather watchers generally. Wouldn't it be cool, totally cool to do the same thing for these other vectors?
For example, areas that were recently glaciated sometimes are rebounding from the glaciation - other areas are going down because of it, and so on. At an incredibly slow but still measurable rate. You can for example, use very high accuracy GPS to measure it.

Bumper stickers of earth and space scientists:
"Stop plate tectonics!"
(written in white on a red background)
"if this bumper sticker is blue you are driving too fast!"

This should be its own thread. What can you do with it? I have managed to get lost.

Yeah I am another one shaking my head at the TV script writer scientific illiterates. There is a vsauce video show earth movement through the galaxy:

Once you have figured out how to travel through time, figuring out where in space to go is child's play. Even though space isn't the same size through time.

That boggles my mind how big the universe is compared to the observable universe. Also I think alan guth said that if inflation is right the universe is 10^47 or 10^34 times bigger then we think. Combine that with the multiverse that has been continuously making more universes over the last 14 billion years. Assuming that was the start and not just when or universe branched off it.
For me that makes the concept of god seem like a single bacteria on earth. With sizes like that a "god like" creature probably could exist and probably does exist. But why it would care or about something as small as earth is beyond me. Maybe we are just a petri dish for some alien's high school science project. Lets hope they decide to keep their project after the science fair. Memories come back of me throwing away bacteria in micro biology class that didn't come out right.
"How is your human project coming out Zorg?"
"I modified the DNA to give them intelligence"
"Did it work?"
"Not really. They have chosen the leader of the free world and it has almost the lowest intelligence of any member of their species."
"Well I'm afraid you are going to have to redo it if you want to pass this class. Set an asteroid on its course to sterilize the surface."
"Not necessary. They have given this creature full control of the nuclear weapons arsenal with no safe guards in place so that it can't use them. This creature also stopped their efforts to use their technology to spot asteroids that might wipe out life on their planet."
