    It's strange how "time" "works" in the Universe. If you think about, when you look to the sky at night, you are seeing the past of many stars... including our sun! But where to look to find it?

    Since everywhere we look in the sky is past, where is the future? Why everywhere is past? Because of the huge distances mesured in light year. Imagine a circle. The earth is in the center. Depending on the size of the radius, you'll be looking to the present or past. For example, when you look to the sun, you are looking to it how it was 8 minutes ago. The sun is 8 light minutes away. This means that in our own solar system we don't have a true time. It's completely relative. So, where is the present? If your circle around Earth have less than about 300.000 kilometers (the "speed" of light), you are in the present. But if it has more, you start to see backwards in time. So... what's time? Surely an illusion created by light...

    We actually live in an everlasting present (even because time is an illusion). If you think about it, what you are reading "NOW", you are reading in the present. And after one minute, you will still be reading it in the present. So, where's the past and the future?

    Another thing. If everywhere you look in the sky is past, where is the future?!?

    Finally, if we discover the direction we are going towards (assuming we live in an expanding Universe), perhaps we can look to where we came from and discover the evolution of our own star... and look at ourselves in the past!

    I guess the future can only be seen if you travel faster than light. Then, you will be able to get somewhere before the light...

    I tend to be of the opinion that there is no future and there is no past. There is only the present.

    The future is merely a prediction. The past is merely a memory.

    You can talk of past and future in terms of observation of events, but it's really all the same. The photons that reach you umptillion years after the emission event are merely a memory of that event conveyed to you by spacetime.

    You can look up, down, right, left, forward and backward, but you can only look to the past.

    What is *really* happening is irrelevant, because we can never detect it, and it will never affect us in any other way than what it does.
