The galaxy is 100000 light years?

Answer 1

Light will travel 983,571,056 feet per second

86400 seconds in one day times 365.242199 days = 31556925.9936 seconds per year

31556925.9936 times 2000000 = 63113851987200 seconds

So the light will travel at a speed of 983,571,056 feet per second for 63113851987200 seconds

983,571,056 times 63113851987200 = 62076958047278002483200 feet

In scientific notation that's 6.208 x 1022

I also just found out that you can type 2000000 light years in feet into Google and it will give you the same answer.

6.2076958 × 1022 feet Other Thought: Obviously lots of us have had the same question. It's helpful to know that light travels at 186,000 miles a second and is a constant for calculations.

Answer 2

A light-year is equal to about 5,878,630,000,000 miles, and as a mile = 5,280 feet, a light year = 31,039,166,400,000,000 feet.

Thus 100000 light years = 3,103,916,640,000,000,000,000 feet.

Answer 3

Let's start with the basics.

A 'light-year' (yes, the hyphen is important) is defined as the distance that light would travel in a straight line through a vacuum in one julian year, consisting of 365.25 days of 86,400 seconds each.

It's more specific than most people realise...

Without the hyphen in 'light-years', the answer would simply be a million years that are a not quite as heavy or dark as usual.

A reminder on how to calculate speed;

Typical equation is S = D/T, where 'S' represents Speed, 'D' represents Distance and 'T' represents time.

Now to crunch some numbers;

Light travels 186,000 miles per second (299,792.458 Km/s) in a vacuum, and this never changes. The only way light slows is when passing through elements.

With this in mind the numbers are already enormous. But they're about to get bigger.

Let's start by working out how many seconds are in a year, as defined by the term 'light-year';

365.25 days x 86,400 seconds per day = 31,557,600 seconds per julian year.

Now, of course for every one of those seconds, light will cover 299,792.458 km.

31,557,600 seconds/year x 299,792.458 km per second = 9,460,730,472,580.8 km per year.

Now of course we need to multiply our answer by 1,000,000 -- The million that you posed in your question.

9,460,730,472,580.8 km per year x 1,000,000 years = 9,460,730,472,580,800,000 km -- the answer we're looking for.

ANSWER B: A million light-years is a million light-years. It is of course a unit of measurement in itself.

ANSWER C: Massive.

ANSWER D: A distance I would definitely need toilet stops for.

Answer 4

This question got by the categorization bots at WikiAnswers, and got itself listed under

Astronomy and Planetary Science. In fact, it belongs under TV Series, Science Fiction,

and possibly Witchcraft.

"Warp" speeds have been referred to only in science fiction, and have never been defined

even there. So there are no numbers to work with, even in fantasy. As we have all seen, it

would take about as much time to go any given distance at any given warp factor as would

suit the needs of that week's script.

But there is very good, hard science, developed over the past century and confirmed thousands

of times in laboratories worldwide, that presents clear reasons, in great detail, for why the speed

of light is a fundamental speed limit of the universe, and can't be exceeded.

I know ... this sounds like the congressman who, in the early 1800s, wanted the US Patent Office

closed because everything useful had already been invented. Maybe there will be a huge

breakthrough in the future, and everybody will be able to get as warped as they want to

and go wherever in the universe they want to be, in an afternoon's jaunt. But so far, there

isn't a shred of experimental or theoretical evidence in that direction, and tons of it saying

it'll never happen.

So the answer to the question is: 100,000 years at least, and probably several times that long.

Answer 5

100,000 light years.

If you want that in miles or kilometers, the math is pretty easy. Light travels at 186,000 miles per second or 300,000 kilometers per second.

There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day and 365.24 days in a year.

Just multiply all those numbers together.

Answer 6

A light year is the time that light travels in one year. The speed of light is approximately 186,000 miles per second, or 300,000 kilometers per second.

There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year.

How far does light travel in 2000 years? Just multiply all those numbers together.

Answer 7

100,000 light years equates to 5.87849981 × 1017 miles.

Or about 587 quadrillion miles.

Answer 8

200 000 light years = 1.89210568 × 1021 meters

Answer 9

Light travels at 30,000,000 meters per second, so 100,000,000 meters would be about 3.33 light-seconds.

Answer 10

Yes, that's the approximate diameter of our galaxy (the Milky Way).
