How can I find how fast I am moving, at this moment, in the universe?

Answer 1

That's an unanswerable question, since all motion is relative. In other words, you can only measure your speed in relation to something else.

Answer 2

Please go to a window where you may look out on a road with cars both coming and going in opposite directions. If you pick a car a random to compare your own speed with, aren't there so many cars going the opposite direction that you see that there is no absolute answer to your question.

So, sitting in front of your computer, how fast are you moving in relation to it? How fast in relation to the moon, right now? (probably quite fast) (Every human moves the length of the earth's circumference every day, what is that ca. 40,041.47 km according to Wikipedia, additionally the earth moves around the Sun, so we are really moving along)

Perhaps, you see the problem. In relation to what in the universe do you want to measure your speed?

Please read Einsteins relativity theory for a better discussion on this subject.

Answer 3

You can't, because velocity is always a relative matter. Are you measuring in reference to the sun, to another planet, to the galactic core, to the Andromeda Galaxy? It is actually just as accurate to say that you are moving at 0 km/hr, with reference to the chair that you're sitting on, as it is to say that, in reference to the sun, you're orbiting at an average of 29.8 km/sec.

Answer 4

It's almost impossible to know *exactly* how fast you're moving relative to a fixed point, because there is no such thing as a fixed point in space (even space is expanding, so nothing is fixed).

However....

At the equator, you're riding on the earth which is rotating on its axis at about 934 miles per hour.
The earth orbits the sun at about 18.5 miles per SECOND (66,600 miles per hour).
Our solar system is orbiting the center of the Milky Way Galaxy at about 486,000 miles per hour.
And our galaxy is moving towards the Andromeda Galaxy at about 880,000 miles per hour.

Add it all up:
You're currently moving at about 1,433,534 miles per hour just sitting on your couch at home.
Cool, huh? :)

Answer 5

You calculate how fast the Universe is expanding by the Hubble constant and there is your answer.

Answer 6

i believe you are spinning at 1000 miles per hour, while travelling 66,000 mph through space

this, of course, assumes you are stationary 'on the earth', otherwise you will be moving AND spinning AND travelling....

Answer 7

You in relation to the universe is 0mph, do you mean this planet?

Answer 8

there's really no answer unless you define a point of reference. every velocity has to be in relation to some fixed point.

Answer 9

Relative to what exactly?

Answer 10

Relative to what ?
