When i was a girl roughly 20 years ago I used to stare at the sun (i had no idea) and it didn't hurt, but now I can't as it's too bright. Has the sun got brighter/stronger?

I was given a best answer to a question I posted involving the void. Bekki B informed me that I misunderstand what the univeverse expanded into. Bekki B states that all the space there is is what the universe expaned into! This means, by definition there can be only be one universe in existance, many others disagree with this. It is becomming obvious to me that everyone is leary of going past the conclusions that are based on the limits of what physistists know down to the last 10-43 sec in time after the big bang came into being. A Swiss physist claims that this time represents the life span of the singularity and that was a state of matter that science does not recognize. Even the most famous equasion of all scientific history, E=MC squared breaks down here, the onlypart of it that existed at that time was the E, therefore the equation was meaningless. The first law of physics to kick in was thermodynamics when the total cold of the void began to absorb the heat of the singularity.

surely the space shuttle isnt the best we can do, but will we ever know due to the costs? or are the space shuttle and all the little toys NASA makes the best possible innovations in space technology

Since the current estimate of the age of the universe is 13.5 bln years, how can we see galaxies that are 13 bln light-years away (as announced this week (7/10/07))? If the universe started at a single big bang point, our galaxy and the newly discovered ones would have to be moving away from each other at nearly the speed of light. And, if that relative speed weren't mind-boggling enough, wouldn't the severe red shift caused by such rapid relative motion render the visible light from those distant galaxies undetectable? Don't get me wrong -- I'm not trying to start a science vs religion argument here. I fully believe the current scientific theories about the nature and origin of the universe. I'm just curious as to this apparent paradox.

I read an article that stated that some astronomers saw some objects that existed roughly 500 million years after the big bang. Since the universe is roughly 13 billion years old is there a point in that exists where we will never be able to see that light? For example if our opitcal technology was unlimited would we truly be able to see the big bang? One note I do understand the fact that light travels at a certain speed and that after the big bang the universe expanded at an amazing rate. just having trouble wrapping my mind around this for some reason.

Apparently they can get through our solar system, but if they place one foot on our soil, they will vanish into thin air. Has anyone else heard about this??

Is the speed of light the fastest or is there anything that's faster than the speed of light, considering that light travels at an astonishing speed of +- 300,000 kilometers per second!

At the moment of Big Bang everything in our Universe came into being within time and space, if so then there must be a position in the universe where it all started as the galaxies within our universe are not in the same position as they were at T+1 ie the moment after singularity

Einstein's observation that mass causes a "depression" in the fabric of space, then what would cause the force needed to "bend" the fabric?

Could the existence of Dark Matter and Dark Energy be proof that our Universe has 2 sides? One side is the observable Universe and the Other a dark or inverse opposite Universe which is unobservable. Each side would be seperated by a Membrane that is punctured whenever Black Holes feed.

When is it a new day and when is it night?

ok i was thinking. .

midnight starts at 12 00

so if "mid" night started at 12 00

would night begin at 6 00 PM and end at 5 59 AM?

and would day begin at 6 AM and end at 5 59 PM?

and since 12 01 is technically a new day would the day start off as night?

me and my friend were arguing whether this is true or not. .
