Is it true that time slows down when you travel at high speeds?
On the one hand, it is true (for all intents and purposes) that if you travel fast enough, time will slow down and you’ll get to your destination is surprisingly little time. The far side of the galaxy is about 100,000 lightyears away, so it will always take at least 100,000 years to get there.
Why do people travel faster than light years?
To go 4 light years at that speed is 4.04 years for us, but for the probe it is only 7 months. The reason has to do with relativity and the twins paradox. You see this principle in the Ender series of books by Orson Scott Card. Ender and his sister travel so much that they live thousands of years Earth time.
Why is it necessary to travel 11km per second to escape?
To do so you would need to introduce some other force, at which point the concept of escape velocity is no longer applicable. At 11km/s you can successfully break orbit and escape the gravitational pull of the Earth. At 10km/s the Earth will eventually slow down your ascent till you begin falling back towards the ground.
Is it possible to keep going up without escape velocity?
Escape velocity is the speed required to escape gravity in the absence of any force being applied. To keep going up requires the continual application of force. So yes, of course it is possible to keep going upwards and further from the earth, but without reaching escape velocity you would eventually be pulled back to earth when the fuel runs out.

Is it possible to travel faster than light?
So, simply going faster than light does not inherently lead to backwards time travel. Very specific conditions must be met—and, of course, the speed of light remains the maximum speed of anything with mass.
Can a ship travel twice the speed of light?
The first ship leaves at 50 percent of the speed of light, so it would take 200 years to arrive. The second ship has some kind of warp drive and leaves at twice the speed of light, 100 years after the first. What does that look like? In relativity, the answer depends greatly on perspective.

Can a two speed motor be shorted on low and high settings?
Most two speed motors use a single tapped winding so if the winding was shorted, it should be shorted on both low and high settings. However, it could be a couple of other things such as a bad switch, relay or run capacitor all of which can be fixed without changing the motor. What model pump/motor do you have?
Why does the speed of light not change?
We also know that the light beam can’t speed up in order to catch the mirror as the speed of light is constant. Something has to give, but what? Speed is equal to distance travelled divided by time taken. Einstein realised that if the speed was not changing, then it must be distance and time that are changing.
