Outer Space question?
828997
I believe you are referring to the changes in the seasons.  Because the rotational axis of the earth is tilted a bit more than 23 degrees away from it's orbital plane the earth gets a bit more in the way of the sun (so to speak) as winter approaches so sunrise is a bit later each day, and sunset a bit earlier.  After the winter solstice less and less of the earth is in the way, so sunrise starts a bit earlier each day, and sunset a bit later, until the summer solstice.  Interestingly dusk is longer in the winter because the sun rises and sets at more of an angle to the horizon.  For the same reason, in the tropics dusk is shorter because the sun rises and sets more nearly vertical.  In the more northern part of the northern hemisphere and the more southern part of the southern hemisphere dusk may last all night long in the summer (culminating in the "midnight sun" north of the arctic or south of the antarctic circles).  In addition, due to the refraction of the atmosphere we see the sun earlier than actual sunrise and later than actual sunset (the atmosphere acts as sort of a lens).

Current information is insufficient to give a correct answer. Once we explore more of the universe, maybe we could have a logical answer.\nst

Outer space...and to the moon.

Firstly, scientifically, the terms space and outer space are the same thing. The problem is that the Earth's atmosphere doesn't stop suddenly. \n\nIt actually seems to depend on your nationality. \n\nThe Federation Aeronautique Internationale has established an altitude of 100 km (62 miles) as a working definition for the boundary between atmosphere and space. This is used because, above an altitude of roughly 100 km (62 miles), a vehicle would have to travel faster than orbital velocity in order to derive sufficient aerodynamic lift from the atmosphere to support itself. \n\nThe United States currently designates people who travel above an altitude of 50 miles (80 km) as astronauts. BTW, this includes 8 pilots of the X-15 rocket plane, one of whom also met the FAI criterion.

This question  has been asked before, hasnt it? Sounds familiar.\n\nSpace is never ending, you can leave the Milky Way and you will enter another galaxy, depending on where ure exit point is.

By "is outer space infinite?" I assume you mean "is the universe infinite?" The answer to this question is NO. The universe and outer space is NOT infinite.\n\nOur current understanding on the origin of the universe tells us that the universe was created in a Big Bang, and that the universe has been expanding ever since (for about 15 billion years). Since light travels 186,000 miles per second, a light-year is about 6 trillion miles or 6 x 10^12.  So 15 billion light years is about 9 x 10^22 miles. This makes the universe very large indeed, but still NOT inifinite.\n\nBTW, this is just the size of our universe. There maybe other universes as other people have indicated, but there is no point talking about them, because we don't know for sure they exist but we are VERY sure that our universe exists.

If the Andromeda Galaxy is 2.5 million light years away and it's the only galaxy on Earth to be seen by the naked eye, it leaves us to wonder how far it really is.\n\nPersonally, I googled it. I couldn't find a thing relating to the blank nothingness further than the universe.\nI only looked a little bit, but there are very few educational guesses on the Internet.\n\nMaybe you should try. Googling that is. Maybe it's you who'll find the right words to search it in.  \nThe words stumped me so the was probably my problem.\n\nGood luck on finding the answer!\n-Marissa

"Space air"?\nIt is really hard to decipher what you are trying to ask.\n\n"Space" is pretty close to being a vacuum (for all intensive purposes for us here on Earth), thus there is no "air" in space.\n\nThe concept of there being some type of medium in space which everything travels through (the idea of an "aether", the material which allowed light to propigate through empty space) has since been disproven over well 100 years ago by the Michelson-Morley experiment.

Aerial.  Its from space.

By that logic, outer space should be a regular tropical paradise.  It has to do with the heat capacity of air.  The atmosphere is thinner the farther you get from the Earth's core, and less air can hold less total heat.  Also, I think the first post about the Earth's radiant heat is probably another factor.

What does this question have to do with "Astronomy & Space"?

Space and Earth have little to do with the event.  I assume that you are referring to the problem of the very fast moving space ship relative to the slow moving Earth.  Time aboard the ship would seem to pass as normal.  Time on Earth would seem normal.  Time passage for someone on the ship as seen by someone on Earth would seem to slow down.  The faster relative velocity of the ship the slower time on board the ship would seem to someone still on Earth.

Be careful how you define "outer space". If you mean outside the halo of the solar system or outside significant graviational influence of the sun, or outside a certain particle density that defines our solar system - nobody has been to outer space yet. I think Voyager I and II are getting close.\n\nMost people that have gone into space haven't even been outside Earth's magnetic field, and none have been outside of Earth's gravitational influence. Theoretically, then, the only people who have left Earth's outer atmosphere went to the moon.

OK, first lets say that the rocket moves at a constant speed of 80% of the speed of light. Working with an accelerating rocket would be hard and .8 is a convienent number.\n\nso we have beta=.8 \ngamma=1/sqrt(1-.8^2)=5/3 and \nbeta*gamma= 4/3\n\nIf you dont understand this, look up lorentz transform in your textbook.\n\nWe will use a two dimensional unprimed coordinate system with distance in light minutes on the x axis and time in minutes on the y axis. The sun is located at x=0 and the earth at x=8 light minutes. Draw 45 degree lines, representing light rays, intersecting the x=0 axis at one minute intervals. Draw a vertical line at x=8 representing the earth. The light ray starting at (0,-8) intersects the earth at (8,0) meaning this is the event where people on earth observe what happened on the sun 8 minutes ago. We will call this event A.\n\nDraw a line with a slope -1/.8 intersecting A. This is the path of the spaceship. It will reach the sun at the time 10 minutes.\n\nNow we will calculate the cooridinates of event A as seen by the spaceship approaching the sun. We have\n\nA'= [gamma       beta*gamma]  [8]\n.......[beta*gamma  gamma     ]  [0]\n\nA'= 1/3 [5 4] [8] =  [13.3]\n.............[4 5] [0]  ... [10.6]\n\n(hopefully the ... makes the matricies line up)\nSo the guy in the spaceship NAMES this point 13.3 light minutes and 10.6 minutes.\n\n\nNow lets look at where the line of the light ray from (0,0) intersects the path of the spaceship. Using trig we get (4.44,4.44). Call this point B. This is where the guy in the spaceship observes what happened on the sun at time 0.\n\nNow lets lorentz transform this point\nB'= 1/3 [5 4] [4.44]  = [13.3]\n.............[4 5] [4.44] ...   [13.3]\n\nnotice that the x' coordinate is 13.3 for both point A' and B'. This is because from the perspective of the guy in the ship, he has not moved. The elapsed time for the guy in the ship between A' and B' is 13.3-10.6 = 2.7 minutes.\n\nSo, he has seen 8 minutes worth of dancing in just 2.7 minutes. The image has speeded up.\n  \n* This is the correct method for solving this problem, but you might want to double check my math.

Dear sir, \n       First, I submit that by UFO you are meaning an extraterrestrial aircraft.\n       \n      Now, here is the deal.  The universe is so large that it LITERALLY is proven mathematically that there are other life forms in the universe.  However, it is also true that they could not have visited earth.\n       Have you noticed that all of the reports started right after 1954's Roswell incident?  And that all the ships are different?  If it truly is an alien race, which it is not, how could it be that so many different alien ships have came and gone without real contact?  It is impossible.  Also, an alien aircraft would be seen by not only the FBI but everybody who observes space in any way.  There would be no way to hide it. \n       In conclusion.  Yes, there are aliens.  No, they have never been to Earth, and they will not for many, many years.\n       \nAs a final word.  Radio Transmissions (The fastest thing in the universe, the same speed as light) will take about 25,000 years to reach the Milky Way.  How could an alien species go for that magnitude of time, get to Earth, and turn away?  And furthermore, aliens are just like us and would we go on a thousand year expedition?

Must have been some terrific star ship if one ship could help earth people kill everything in the universe.\nSince we can see out 13.8 billion light years, that's a heck of a lot of space to rocket around in to find everything to kill.\nBut since there are still some earth people left, maybe we'll just repopulate the universe.
