Aren't we already traveling super fast away from the point big bang? That's what I don't get. How can you not be moving if the universe is expanding?

lol you can view the past right now just look at the stars. technically, everything you see is the past.

It's their past, but it's our present. Also, for time dilation, 'time goes slower for you if you move faster' is a bit misleading. Time in your reference frame is the same, but from the reference frame of a slower observer time in your reference frame is slower. From your reference frame the time in slower references is faster. Hence the phrase "it's all relative".

yes, we are on a planet that spins roughly 1000 mph 9depending where at in the world yoe are (faster on equator), circling the sun at 67,000 mph, in a solar system circling the milky way at 490,000 mph, which itself (the milky way) is moving through space at 1000k/second which is roughly 670 MPS or 2.24 million MPH

So how can you slow down?

find a space in "space" that is far enough away from EVRYTHING that there is little to no effect of gravity and hover there in one spot without moving..... i think it is NEARLY impossible to do :D

The bartender says "we don't serve neutrinos here".

A neutrino walks into the bar.

This speed limit, as discovered by Einstein and others, is one of the most amazing and extraordinary features of our universe.

It all comes down to this: Light moves in a strange and bizarre way. It moves in a way that is very different from how anything else moves.

Normal objects move with a speed that is different for different people, depending on how the people are moving. The speed of a beam of light is the same, no matter how you move relative to it.

If a car is driving toward you at 30 miles per hour, and you run toward that car at 10 miles per hour, then you are traveling 40 miles per hour relative to the car. The speeds of normal objects add up in a straight-forward way.

The speed of light isn’t like that.

Every beam of light travels through space at precisely 186,282 miles per second. That speed never changes, no matter how you move relative to the light.

If someone shines a beam of light towards you, and you drive toward the light, you would expect that, relative to you, the light would be traveling just a little faster. But it doesn’t!

If someone shines a beam of light toward you, and you drive away from the light, you would expect that, relative to you, the light would be traveling just a little slower. But it isn’t!

Every beam of light always travels at precisely and exactly the same speed, no matter how you move. This was discovered in the laboratory more than 100 years ago, and after a century, this bizarre result has been double-checked and verified millions of times.

But how is this possible? It seems as strange as if a laboratory experiment showed that one plus one does not equal two!

Explaining this mystery was one of Einstein’s greatest discoveries. Speed is a relationship between distance and time. If you drive a distance of 100 miles in a time of two hours, then you must have been averaging a speed of 50 miles per hour.

Einstein knew that if distances and times are the same for everyone, then speeds must be relative. However, because the speed of light is not relative, then distances and times must be different for different people.

Something that takes five minutes on my watch might take four minutes on yours, and six minutes for someone else. The only way for every person to measure the exact same speed for every beam of light, no matter how the person is moving, is if times and distances are distorted for different people depending on how they are moving.

This means that time slows down for fast moving objects as they approach the speed of light. If a person could reach the speed of light, time would stop completely for them.

That’s why no spacecraft could ever accelerate to a speed faster than light.

Our universe is a crazy place, organized by a weird and wonderful set of rules. The speed of light is a strange and perplexing thing, which has changed our understanding of even very basic things like time and distance.

So is someone gonna answer the fucking question?


Edit: well to save everyone some time, namely those who are going to answer "why don't you search for the answer yourself instead you twat", I've researched the answer and the answer isn't to my total satisfaction:

New question: why is the speed of light not relative?

It's impossible to be in a region within the confines of the universe, and be completely uninfluenced by gravity.

Yeah because if you weren't moving, your heart wouldn't be beating, so you'd be dead.
