Math Test!!?

Question

This is the test:

Number of planets in the universe
Plus number of months in a year
Multiplied by number of days in a week is...........

Pluto is included, okay...

Answer 1

Answering this question is IMPOSSIBLE. If we counted Pluto, we would have 9 planets in our galaxy. Because of this, you'd think the answer would be (9+12)*7 = 147. However, the question is asking about the number of planets in the UNIVERSE, not the galaxy. Scientists have already discovered some planets in distant galaxies, but not all of them. Therefore, answering this question is impossible.

Answer 2

Actually we don't know how many planets are in our universe, but we also don't even know who many are in our own galaxy (Milky Way Galaxy). All we know is the amount in our own "Solar System". There are nine (or eight or 10-12 depending on if the dwarf planets are included: "Pluto","Xeno/Eris", "Ceres" and "Charon").

The nearest "star" to our own sun is Alphi Centuri (in the southern cross) which is actually three stars, which northerners don't see. It is also in the Milky Way galaxy and looks like it might have planets. It is a little over 4 light years away. The nearest galaxy on the other hand is 25,000 light years away! The nearest galaxy around the same size as our own is the Andromeda Galaxy, 2.5 million light years away!

Solar System (smallest) ->
Galaxy (group of stars in orbit) ->
Known Universe (everything seen) ->
Universe (everything known) ->
Multiverse ???

The reason for the difference in Known Universe and Universe, is some objects are thought to travel faster than light speed, due to the Universe expanding (accelerating reference, not inertial reference like High School physics, so faster than light is possible). Some galaxies near or on the edge of "the known Universe" might someday "disappear" and we will never be able to travel or even communicate with them ever again, even though they still exist. Typically, the farther something is from us, the faster it is traveling away from us. So when the objects get far enough away, they will be traveling faster than light. So minus a worm hole or bending space-time, these objects are "here today", "gone tomorrow". How would you count these planets, even if it was possible?

There are some distant objects that are heading towards us however, like some Galaxies which will collide with the Milky Way. The Sagittarius Dwarf galaxy (collide in 100 million years) and the Andromeda galaxy (collide in 3 billion years = 3,000 million years). Galaxies are mostly empty space, so when the galaxies collide/merge, the chances of our Solar System being directly hit by something in the other galaxy is rather small.

Here's a nice size comparison of stars:

Hope this helps explain how massive the Universe truely is.

I also want to add that the inside of a black hole is outside the known Universe to us, since we can't see in them. However, anything inside the Black Hole (inside Event Horizen) can still see out and see everything in the Universe that we can. The other example I gave before is different because unlike objects in a black hole, objects on the edge of the Universe will disappear from us (like a black hole), and we on Earth will also disappear from them (unlike a black hole). So they will become a new sub-Universe separate from us after a period of time.

Answer 3

Impossible to say the number of planets in the universe

Answer 4

There are innumerable planets in the universe, Hence the answer is
alpha + 12 * 7
= alpha*7
=alpha
where alpha means infinite

Answer 5

What a ********* answer, how can anyone count the number of planets in the universe, if you can't even count the planets in the universe how can you found the answer.

Answer 6

number of planets in the universe would be tricky... maybe if she asked number of planets in the solar system it would be a little easier

Answer 7

147

Answer 8

HEY THATS A TRICK QUESTION

CUZ PLUTO ISNT A PLANET ANYMORE

Answer 9

you're joking right? it's not that hard

Answer 10

ask GOD :)
