Is it probable that Mars' orbit could change or something?!What do you think?

there is a 1 in 75 chance that it will happen. If it does, it will create a crater the size of the one in Arizona, and actual balls of fire will be shot out into the universe. What do you think? Did you even know about this? Thanks!

is space itself infinite? If so, Is it possible that another big bang in some other quadrant of space started another universe?

I just got a meade lxd75 telescope. Prior to buying that, I bought a mySky. I have all the cables I need to connect the mysky, but no matter what I do, I can't get the mysky to point the scope anywhere. I'm bringing it on a trip tomorrow, so I need some help ASAP.

It's my husband's birthday and he got himself a telescope. The user's manual says we can see saturn's rings and the moons of venus .... It has a diameter of 12 cm, I think. We havent's tryed it yet as the sky is cloudy here.
Whatever, I know there are bigger ones if your willing to invest a few more bucks.
Here's my question: What kind of telescope do you have and what have you seen with it? (How far away was the object?)

If we assume the big bang theory is correct, in that the universe is expanding from an infinitely dense object taking up no space, it will one day contract/collapse to the same dense object and this expansion/contraction is a cyclic thing, what do you think is the likelihood that each cycle evolves human life or life of an equivalent level of advancement? ...and do you think there will ever be a chance for mankind to escape the big collapse?

And lets assume mankind could travel to the planet (taking about 25 years or so) And if that planet had oxygen,trees and new animal lifeforms and no humans.

Would you like to live on the new planet or you would rather stay on earth?

Question for any of you with insight into the astronomical world: Isn't a large scale impact on Mars a BAD thing for humanity? In the news they keep saying how "excited scientists are," but couldn't this set back our society for potentially decades? Wouldn't a large scale impact make the Mars environment too hostile for human exploration, and being that it's really the only planet other than ours that we can explore safely, leave us with a great deal of lost opportunity until the planet stabilized?

Obviously there are still many other bodies worth exploring, but Mars I'd say is the most reasonable foreign body other than our moon. Even to go to the Jovian moon's would take a great deal more advancement and travel time.

If you could, would you go on a manned mission to Mars?
Knowing full well you wouldn't see family and friends for a MINIMUM of two years, and that the mission would be fraught with danger, and an innate fear of the unknown?
Why or why not?

The other day i was on my PC and i took a break and i noticed the moon out of my window. It was a brilliant white half moon and for some reason i was transfixed and had to keep looking at it. After about 45 seconds the darkness started to work its way slowly across the moon until it completely disappeared. It was quite the unusual site, which is the first time i have ever seen it happen. Have you ever seen this happen?

I have read Newscientist magazine today and it says this will be ''a cocktail of recycled human urine, sweet and rat pee''. How do they mean? isn't this urine mean the real urine we all know?

Why isn't my pop- up blocker working on these annoying 'GAP' video splashes now gracing the pages of this forum?
Are there setting I can apply to knock them out, or am I relegated to just dealing with them over and over every time I 'refresh' the page to view and answer new questions?
This is well on its way to making me crazier than usual!!!

How did the water evaporate?

How are scientists going to beat the radiation problem to colonize?

I don't think the situation on mars can be over come for long term human existence.

If The interior of Venus is composed of a central iron core and a molten rocky mantle, similar to the composition of Earth, then why isn't Venus projecting a magnetic field too?

A day on Venus (243 Earth days) is longer than a year (224.7 Earth days). The rotation is also opposite from that of Earth, with the Sun rising in the West.

Does the direction and rate of rotation have to do with the lack of a magnetic field?

I don't understand...

I have a Mars Question too...

I was checking out those really great pictures posted a few questions back and I started to think about the psychological impact behind it.
I really do think I'd filp out and be in shock. So, I just wonder how they manage to stay focused.
Thanks.

My groundskeeper on Mars swears that a rather large asteroid will hit the red planet on January 30, 2008 - less than six weeks from today. Houston, how is this gonna affect the real estate value of my Martian villa? And where can I find a good cleaner to wash off the red gunk from the walls? Any advice will be deeply appreciated.
