Green house effects are necessary to keep the planet habitable, and have been strong in the past. Why is the current rapid change a worry?

and it feels like gravity, and so earths gravity is like a constant acceleration, then what are we accelerating away from?
Could it be other galaxies?
Could be creating more space between galaxies?

with equipement . or are they all based on opinion? Is there real proff of black holes and what is the mph of suction speed, any ideas? I mean, has anything ever fallen into one that we know of? thanks

it maintains a feeling of earths gravity, right?
Same effect as on planet earth.
Then is it safe to say gravity is like a constant acceleration?

If you were traveling in any type of vehicle, could you in any way, keep up with the sun?
Could you follow the sun fast enough to where it would always be daylight?
I was wondering about this and it's really driving me crazy!
Please answer!

We all know that the world is split up into different time zones.....so let's assume that in London the time is midnight (on the Greenwich meridian).....so what would the time be at the North pole????

"When" the USA put a man on the moon, can anyone please explain why there were no stars in the pictures? Our atmosphere stops us seeing most of whats there but away from cities and the street lighting etc, you can see billions of them. Surely on the moon you should see even more?
Also, how did the astronauts survive the tremendous radiation without suffering radiation sickness/burns etc. I was taught that getting through the Van Allen belt would probably kill someone and cosmic rays when sun spot activity was so high would undoubtedly have finished them off.
I'm not a conspiracy theorist, just someone who cant work out the above problems.
Please don't rant as most from USA usally do, just explain in rational terms.

Because it is so hard to separate the facts from the religious crap. that i dont know whats really going on.
Will the earth get knocked off its axis?
Will the sun change its axis?
What planets will really align in 2012. Venus,Mercury,saturn.
What happens when the suns new 24th 'sun spot' change thing happens?
And just basically what will happen 2012 comes threw?
Will the maya calender really end, or a new cycle of sorts starts?
If it does end, Why?
What does NASA and the GOVERNMENT(s) think of this?

What does Nostradamus really predict about 2012?, and not what the media is hyping up about it.

If we could travel at the speed of light, it would be possible to escape time thereby negating the concepts of hours, minutes ~ years. Thus we could move from anywhere to anywhere in an quantified instant, making the most distant parts of this universe just a hop, skip and a jump away (minus the skip and the jump). Am I looking at all that correctly?

And how far are we from achieving that, short of a monumental breakthrough Quantum Physics?

Here's the idea: Time does not exist. The universe is made up of cycles things die and things are born. There is no such thing as a beginning or an end. For example, a seed is planted and grows the plant dies but it has planted more seeds. The universe never began, it just always existed.. The world is recycling constantly, all elements of space and all atoms are recycled, atoms are shared...

As it was shown by Einstein, time duration is relative. What is millenia for earthling scietists, is just few days by God's clock (assuming God moves fast enough).

1) What is the wavelength of a 100 M-Hz(100FM) radio signal?
2)What would be the frequency of an electromagnetic wave with a wavelength of 12800?
3)Estimate the frequency of an electromagnetic wave having a wavelength equal to the size of the period at the end of this sentence. In what part of the electromagnetic spectrum would such a wave lie?
4) What would be the wavelength of an electromagnetic wave having a frequency equal to the clock speed of a 3.2GHz personal computer? In what part of the electomagnetic spectrum would the wave lie?
Thanks!

The moon has many interesting features, like it-s own rotation matching precisely the earths and thus showing us the same face all the time. But one thing I'm not suer is if there is a physical or mathematical reason why the moon eclipses the sun so perfectly (even when it lets a small ring of sun to show), or if it is just a very nice coincidence on it's size and distance from the earth to give us such beautiful events?
