Okay, I will pick the best answer, but answer wisely.

1. Do aliens exist?
2. What time is it?
3. Why is the sky blue?
4. If you're traveling at the speed of light and turn on your headlights, then what will happen?
5. What is happening before the big bang/universe creation?

1. Most likely (or picking crops in california)
2. depends on where in the universe you are
3. refraction of the sun's rays
4. impossible, you wouldn't be able to travel at the speed of light
5. An older universre collided creating a new one

1. Possibly, but I myself do not have any scientific evidence of the existance of aliens. Astronomers have located planets throughout the galaxy that have ideal conditions for life but so far no life outside of earth has been located.

2. It is 1726 EST where I am.

3. The sky is blue because of nitrogen in the atmosphere causing the light from the sun to scatter. Most of the longer wavelengths pass right through and are reflected back in to space. When the sun is setting and rising the sky appears yellow or red because those longer wavelengths have more atmosphere to go through and are absorbed consequently.

4. Light always travels at the speed of light compared to the observer. If you are traveling the speed of light and you turn on the headlights then the light from the headlights doesn't travel double the speed of light. Instead, time inside the space shuttle will come to a halt to allow light to travel at it's regular speed. The lights will shine like normal.

5. Again...we have no clue on how the universe was created.
But a good book you can read on the subject is called " the whole shebang ". I am reading it right now and it explains a lot about the big bang theory. I hope this helped! CYA

Q1: Do aliens exist?
A: Yes, aliens exist. Definition of alien:An unnaturalized foreign resident of a country.(noun version).
Q2: What time is it?
A: No one could never know the exact time. Especially since there are time zones and there are many different times. Where I am now it's 1:42 though.
Q3: Why is the sky blue?
A: The sky is blue because there are molecules in the air that scatter blue light from the sun more than they scatter red light.
Q4: If you're traveling at the speed of light and turn on your headlights, then what will happen?
A: They will probably not make a car that can travel at the speed of light, possibly an aircraft but never a car. If they did happen to make one that can travel at the speed of light without ruining the human form I'd say that Your headlights would show because why wouldn't you be able to light at the speed of light ( i hope that makes since ).
Q5: What is happening before the big bang/universe creation?
A: Well seing as the big bang is only a theory we don't really know what happened before it because we don't know if that is even how the earth started. So there is not enough support to say what happened before. But I'd say that there was just other universes doing nothing we could explain.
So that is all my answers; I answered to the best of my ability.

1. Yes...but it really depends on what you considered as alien. It's a bit arrogant to say that aliens don't exist when we're nothing more than a speck of dust in the universe. The it's highly possible that aliens do exist in my opinion.

2. 1:07pm

3. The sky is blue because the molecules in the sky is blue. So when light hits it, it reflects blue. Same reason why water is blue. The molecules are blue.

4. Nothing will happen. You probably won't even see the light turn on because you're already traveling at the speed of light and nothing to our knowledge is faster than the speed of light.

5. We are living in the past and future of the big bang. The big bang is a moment in time when everything is one. The singularity in which the universe collapses on itself and explodes into what we know as the universe. Black holes suck everything back in, the big bang is what sends it back out.

Have a great day.

1) Yes, of course. There's too many other stars for there not to be life somewhere else in the universe. Have we experienced visits from aliens? I don't have a clue.

2) 3:16pm

3) Its reflected sunlight.

4) The obvious answer is nothing. But digging a bit deeper, if you're travelling at the speed of light, would you actually be able to reach forward to turn on the headlights? I seriously doubt it. On the other hand, if you're in a bubble, say 100 yards in diameter, and the entire bubble is travelling at the speed of light, then your motion within the bubble will appear to be zero. So when you turn on your headlights, the back wall of the bubble will be illuminated.

5) Nobody knows. But if the cyclical universe theory is correct, then before the big bang, the previous universe was collapsing in on itself. The cyclical universe theory suggests that since we seem to be travelling outward, away from a central point, the point of the big bang, then we will stop travelling outward when all the energy from the big bang that propelled us outward is exhausted, then gravity will slowly, ever so slowly start pulling the cosmos back in on itself. And at some point in the far far distant future, we will all return to the point of the big bang, and create a massive cataclysmic event, in which the big bang happens again, and the universe is reborn. But what happened before the FIRST big bang? And how long will it take until all of the energy of the universe is exhausted and there are no more big bangs? And what happens afterwards? When the universe ceases to exist? What is on the other side of the end of the universe? When the universe ceases to exist, is what's on the other side of the universe on this side too? What is left? Too many questions....I need to go lie down.

#2 revisited) Its now 3:33pm CST

1. Yes. Any person that does not have citizenship in a given country is considered an alien.
2. Daytime (or if you are 12,500 miles away, nighttime)
3. Nitrogen. This gas refracts mostly blue light from the sun to earth.
4. Your headlights will turn on and apear to travel away from you at the speed of light relative to your perspective of being in the car.
5. The membranes of the multiverse were slowly vibrating towards each other until finally some collided and formed our universe. See M-Theory for a more indepth explanation.

1 NO
2 2:40 pm on 7/26/07
3 reflected sun rays back into space by the earth and the ocen water that reflects most of the light
4 the same thing that happens when you take a picture of a car moving at 70 mph
5 couldn't tell I was not there

1) Of course we do.
2) Time is an illusion - it is always now.
3) The sky color was picked using focus groups. If you don't like it, complain to the marketing department.
4) Since your perception of time comes to a halt, nothing can happen. Or maybe the wipers will come on instead; scientists aren't sure.
5) Interminable public hearings to finalize the plans.

1. Of course, havent you seen the movies?

5. Alot of filing and paperwork for the making of our universe. And you thought filing a claim took alot of paperwork...
