I'm looking into either psychiatry or clinical psychology, and I've always ahd this dream of becoming an astronaut. is it possible? What has there been in the past?

Passed away civilisations in the outer space also has had a convex gasshield that like a parabola delivered the toughts into billions of parcecs away, different distances, different times ago. It takes time continusly as long as they did exists.
Receiving brought the human mind onto existent level.
Also, the human civilization's higher attempts will be used by hundreds of millions, if billions of yrs later -by then forming intelligent life.
Physical contact is impossible with them, either fourth, or back in time.

If we observe a galaxy at 40 billion light years distance can we say that light given off by that same galaxy today will take 40 billion years to reach us? Assuming it hasnt "moved"? basically I am asking if distance has always been constant given that space itself has "expanded." More fundamentally I am asking if when the universe was "smaller" (ie. less expanded) then was the a light year of long ago the same as a light year today.

If you know the diameter of an asteroid, how do you find the volume?

If an asteroid's diameter is b/w 47-100 meters
and it's velocity relative to earth is 13.0 km/sec.
and the composition is unknown.
and we know that it has come w/i 0.0409 AU of Earth...

what is the maximum amount of energy that would be deposited on Earth in the worst case scenario?

How do you calculatet his?
It's telling us to us the kinetic energy formula which is: 1/2mv^2.
But I don't know how to find the mass of an object if we have the diameter.
Thanks! :D

I understand from basic Physics at school that an item must travel at a particular trajectory around another item floating in zero gravity in order to be picked up into orbit. I was taught that satellites are maintained in orbit through physics alone, because they are caught in the gravitational field of Earth, while traveling at a particular angle, which prevents them from ever colliding with the planet. I was also taught that gravitational fields only occur in zero gravity. Does this mean that any item traveling in zero gravity could take things into orbit? For example, could an astronaut, floating in space, place small items into their own orbit? Is orbit determined purely by the size of the orbiting item in relation to the item it orbits, or does an item have to be a certain size to develop or enter orbit?

There are billion and billions of stars smaller and larger than our son, billions of light years out into the universe there are stars just like the sun. With a strong possibility that they have planets orbiting around them... It's VERY narrow minded AND arrogant to think that Earth is the only planet with life, and that the rest of the universe is just a pointless waste of space... what makes people think they have some privilege as humans?

Christians as well with their "Eve is the mother of all life", although not all of them are that stupid.

i live in the north of england and set off to work at 6.30 am. when i come out of my back door and the sky is clear (its mostly cloudy!!) there is a very bright object in the sky. i think i'm looking east and i'm pretty sure its venus. am i correct? also if i look to the west more or less 180 degrees there is a little red star. could this be mars? i've tried using google sky but my pc is too clogged up with crap for it to work properly so i cant use it!! thanks

I've always been interested in the solar system's natural satellites (or moons), and how varied and unique each one is. We have so many worlds to explore in the future. So, which one do you think is the most beautiful or your favourite? Why?

Can one learn about the structure of something of which one is a small part of the structure and cannot travel far from their home location? If you lived in an apartment but could only look out the windows (and what if every wall of your room does not have a window and you cannot leave the room), how could you tell if you were in the center of a city, town, village or in the middle of "nowhere" or in the "transition region" between the combination of any of the above? You cannot 'make' a window by knocking a hole in the windowless wall...

I need a connection to the structure and our location in the Milky Way Galaxy

You know how scientists say that life cannot exsist without liquid water? Well is that statement completely true when it may come to life on another planet? How can this statement be true if science hasn't been able to physically take human life to another planet, or observe planets out of our solar system? Wouldn't this rule only apply to life on Earth.

As you can see in the video (sources) the takeoff speed/velocity of Apollo is look like very small and after certain height it should fall again on the moon’s surface by its gravitational pull which is six times weaker than earth. Also was rocket fired for escape velocity from moon’s gravitational pull. How many total number of rockets were used for changing direction and speed in this mission, when and where? Any idea or source.
