Depends witch star it comes from. The closest stars light will only take 7 years but most of the stars (that are relatively closeby compared to the light of other galaxies) will take 200 or more.
It take the light to travel for 2 million years Actually about 100 years, maybe less.
Waves can travel across the ocean just like ripples across a pond and as long as they do not encounter adverse conditions they do not lose much energy.
Approximately 2.5 secs. A 'microwave' is an electro-magnetic radiation, in the same manner as light, and uv. radiation. Being an electro-magnetic radiation it will travel at the speed of light, which is 'c' = 3.8 x 10^8 m/s
Well the earth cannot travel around the world being as they are the same thing. However, if you meant how long does it take the earth to travel around the sun then the answer would be about 365.25 days.
surface waves, raleigh waves, and long waves.
Approx 100000 to 180000 years.
It take the light to travel for 2 million years Actually about 100 years, maybe less.
it would take you approximately 100,000 years to travel across the milky way. happy traveling :-) !
The Milky Way is estimated to be about 2,000 light years thick, but about 100,000 light years long/far... Which i guess you can tell, thats a lot.
We're not sure where you posted the question from, but we on earth are not burdened with such a question, as we are already located in the Milky Way.
Between 100,000 and 180000 years.
Between 100,000 and 180000 years.
Light travels 186,300 miles per second
The Milky Way's diameter is about 100,000 light-years.
It takes about 997.186 seconds for light to travel across the diameter of Earth's orbit.
the earth is part of the milky way galaxy if that was your question.
A disk has multiple speeds - at it's perfect center it's standing still (as you approach the center the speed gets smaller and smaller as you approach 0) At the outer rim (where our star Sol and it's attending planets) are rotating around the galaxy center at about 500,000 mph, ~0.0007% of the speed of light.
