Standing still

You may think that you are standing still. You are on the surface of a planet rotating at a thousand miles per hour. (Here in Columbus, Indiana at a latitude of 39.2 degrees, we are only moving at 803.6 MPH.) The Earth orbits the sun at 67,000 miles per hour or 18.6 miles per second. (This changes slightly because the Earth's orbit is not exactly circular, but elliptical. Since the Earth is the closest to the sun on January 3rd, the perihelion, that is when it would have the most velocity. Since it is the farthest from the sun on July 4th, the aphelion, that is when it would be moving the slowest.)

Our entire solar system orbits the center of the Milky Way Galaxy at 514,000 miles per hour or 143 miles per second. This is roughly 1/1300 the speed of light. Still, it takes 230 million years to travel all the way around the galaxy.

The universe is expanding. Most of the galaxies are moving away from each other. The Milky Way Galaxy, which you are a part of, is moving at 1.3 million miles per hour or 361 miles per second. This is roughly 1/515 the speed of light.

Fwd: Better motor

From: utahtrout 

they claim that its motor, the Linear Labs Hunstable Electric Turbine (HET) will perform so much better than conventional motors that electric cars with these motors can eliminate any sort of gearboxes, expect 10 percent more range from a given battery size, while providing more power and torque for a given size of motor.

Renewable Energy is a Scam

Fwd: Mosquitos change everything

How Mosquitoes Changed Everything

They slaughtered our ancestors and derailed our history. And they're not finished with us yet.

Why I believe in UFOs, and you should too... | Ben Mezrich | TEDxBeaconStreet

I'm extremely skeptical.  There is a real lack of evidence.  

The distances between stars are so vast that the energy requirements for interstellar travel are by our standards almost infinite.  The cost of the moon program in modern dollars was around a hundred billion dollars.  Sending little robots to Mars costs several billion dollars.  Any kind of interstellar program would cost at least a trillion dollars.  It is not about money.  It is about resources required, either by us or by another civilization, which are enormous.

There are also practical considerations.  Space is very radioactive making it impractical for travel.  It takes a great deal of effort to keep humans alive in space.  Also, anything moving faster than 1% the speed of light is in danger of being obliterated by a grain of sand that happens to be in the way.  At 10% the speed of light, the super thin interstellar gasses, although almost non-existent, are enough to create considerable resistance.  I have heard that it would difficult to go any faster than this.

For this reason, if I were designing an interstellar craft, I would make it shaped like a giant needle with it being very thin.  I don't know if this is practical.

If the universe is only 14 billion years old, how can it be 92 billion light years wide?

There was a time when parts of the universe were moving away from other parts of the universe faster than the speed of light. That time is right now. The point is space itself is expanding everywhere at a very rapid rate. It was even more in the very early universe, during a period called super inflation. Then it settled down to something reasonable, but because of Dark Energy, the expansion will become greater over time.

This video explains and clarifies what we mean by the visible universe and the microwave background radiation. However, it takes some effort to understand it.
