Luckily, I'm smart enough to realize that I am having an illusion, so I disregard my vision, as it is not accurate at 29,000 MPH.

I'm not asking how fast an alien is traveling, nor do I care, because his speed has nothing to do with my actual height. If he has an illusion of me shrinking, that's his problem, not mine! I didn't shrink just because he went fast.

So the faster I go, the more you shrink? How tall do you measure yourself if I travel 29,567 MPH past you?

But the light you are viewing from the astronaut on the moon is old, outdated, obsolete light! It has a delay from the source to you. Your measurements of the event are inaccurate. The measure of the distance traveled is accurate if you count the revolutions of the wheel, and multiply that by the circumference of the wheel for a distance traveled. Acceleration is caused by force, and torque is force times distance (from axis). 2 lbs on a handle of a 10 foot bar is 20 lb-ft of torque. 2 lbs on a handle of a 20 ft bar is 40 lb-ft of torque. Force times distance! So you get smaller if someone else looks at you from a distance?

The measurements that the astronaut takes are accurate, everything else is an illusion. We are not measuring how far the moon traveled, we are measuring the distance the astronaut traveled on the moon. That's what we are talking about, correct? How tall are you?

The only measurements I can comment on as an observer are the measurements that were taken of the actual event. I can then look at the measurements and see what really happened during the event, AFTER the event has already occurred.

When the astronaut finishes his travel across the Moon, he will report the actual numbers that he traveled. My observation doesn't change reality.

If it disagrees with the astronauts measurements, I am wrong, PERIOD! The astronaut already measure the distance and time that he traveled. The numbers don't change, the illusion does.

What do you mean I am measuring his velocity wrong, that is my observation form the Earth. You mean, when talking about velocity that there can only be one reference point, and that is the perspective of the measuring tape and stop watch of the actual distance traveled in the actual duration?? Now you are switching the rules and telling me as an observer that I am having an illusion?? Why do you keep switching the rules? I am an observer, correct??? :rolleyes:

So when I look at a full moon at night from the Earth, it appears to me to be about 1 foot in diameter. If there was a astronaut on the edge of the left edge of the moon from my perspective, and he travels to the right edge of the moon in 12 hours (my time), did he travel .083 ft/hr? And likewise, giving a speed means that that speed has a reference point for all to play the game by those rules. You can't switch the reference point and still use that given velocity in the middle of the game.

I'm not the one who said the train's velocity is 20m/s. Since you already established a velocity, I have to play by those rules. The train is traveling 20m/s, so is the ball. The ball is then accelerated to 30m/s.

You set the rules, I am playing your game, remember?

OK, I'll play your imaginary, hypothetical, fairytale. What is my initial velocity?

I didn't forget to add squat! You TOLD ME the train has a velocity of 20m/s. Make up your mind, what is the velocity of the train??? So the train has a velocity of 0 m/s. The ball is accelerated to 10 m/s.

So you're saying the train's velocity is 0 m/s, then?

The train's velocity is 20m/s, and the ball is traveling with the train at 20m/s.

The ball is ACCELERATED from 20m/s to 30m/s. The ball was at rest at 20m/s. It had an initial velocity of 20m/s. It has already been established.

The people at the train station standing on the Earth measure the train at 20m/s. If you want to include the Earth's velocity than you need to tell me what initial velocity the people at the train station have. You said the people measure the train at 20m/s. Don't change the story afterward.

So accelerating to .99c "almost instantly" is not breaking the laws of physics? What is the acceleration rate of that scenario? If that acceleration rate is maintained for 1 second, what will the velocity be? How about two seconds? three? 10 minutes? Surely you can maintain that acceleration rate (same force) for those time periods? If not, why not?

If the train is moving 20m/s, and the ball is 0 m/s relative to the train, the ball is also traveling 20m/s, and so are you. The radar gun on the train has an initial velocity of 20 m/s. If the ball is sitting on the table on a train traveling a velocity of 20m/s, how fast will the people at the station measure the ball on the table as the train passes at 20 m/s??

Did you forget that the initial velocity of the ball is 20m/s? If you threw the ball in the same direction of travel of the train, you accelerated the ball an additional 10 m/s, is all you did. It had an initial velocity of 20m/s, and a final velocity of 30 m/s.

Just hypothetically, my car accelerates to 186,000 mi/sec in one second, and travels 93,000 miles during that one second. Oh, did I mention the engine only has 400 lb-ft of torque at 3,000 RPM?? No need for actual numbers, we are playing pretend physics with pretend vehicles, that accelerate against the laws of physics. But that shouldn't be a problem for most of you, UNLESS, someone else says it, then you pick it apart! :rolleyes:

Can you give an example of empty space, and how can it be empty space if I am there? If I am the only object in empty space, where did I come from, and where did my space ship come from? If I am traveling at a velocity, how did I get to that velocity? Did I accelerate to that velocity?

1. Acceleration doesn't occur instantly. E=MC^2 (Energy=Mass*The acceleration of 186,0000 mi/sec^2). C^2 is an acceleration value of 186,000 mi/sec^2. In order for an object to accelerate to ~ the speed of light (186,000 mi/sec) in, say, .5 seconds, from an initial velocity of zero, the acceleration would have to be 373,000 mi/sec^2, and at that acceleration rate, the ship would be traveling 373,000 mi/sec after 1 second. Can you tell me what the actual acceleration of the ship is, and stop talking about impossible scenarios? 2. How was the 5 light year distance determined? 3. How was the velocity of .99c determined? 4. Are you assuming an initial velocity of zero? 5. How long does it take for the ship to reach the velocity of .99c from an initial velocity of zero? 6. So Andromeda is 2.5 light years away. That means traveling at the speed of light (186,000 mi/sec) it would take me 2.5 years to get there. If I travel at the speed of light towards Andromeda, and the distance becomes only a walk in the park, and a walk in the park is ~1 mile, why does it take me 2.5 years to travel 1 mile at the velocity of 186,000 mi/sec?

How was the velocity of .99c determined? How was the distance of 10 light years determined?
