What do you think? (Space, Galaxies, Aliens?, Unbelievable Numbers!!!)?

Question

Numbers play a big part in this question - FACT - Our Sun is 1 of over 200 Billion stars in the Milky Way Galaxy.... FACT - Nasa's Hubble Telescope has found an estimated 1500 other Galaxies, in a very tiny "empty" part of the sky.... each probably made up of billions of other "suns".... this portion of the sky is the same size as looking at an american dime, or a british 20p coin, at 75 feet away... (source: http://hubblesite.org/newscenter/archive/releases/1996/01/text/) bear in mind this was over 10 years ago. What are they not telling us? Chances for life outside our own galaxy? Maybe we are not the only humans in the universe? If anyone can work out a rough statistical analysis for the chances of life? (of the whole sky) Please people, go wild with this one!!! :)

Answer 1

The Hubble telescope has found1500 galaxies in a tiny area of the sky. Still it can see only a short distance.

As the universe is of infinite size we cannot see the edge, there is no edge of the universe. As the whole universe is filled with stars and galaxies there are an infinite number of stars in the universe. and there is an infinite number of places that has conditions like Earth that could support life.

But the chance of any life existing outside of earth is zero.

The theory about life out there relies on the theory of evolution, a theory that relies on at least one of Newton's laws to not apply to some situations.

So, the concept of aliens can be dismissed along with other fairy stories like evolution and the big bang.

Answer 2

here's a figure to look at if you like cool numbers:

i did some calculating in my spare time and i came up with this figure:

in theory there are approx. 750,000,000,000,000,000,000 solar systems in the visible universe. the visible universe is the part of the universe that we can observe from earth. there are about 35 million documented galaxies in our visible universe. so what are the chances that life is limited to our solar system?

Answer 3

That is all old news. Many scientists are actively searching for proof of this alien life in the SETI program. Nobody is hiding anything. There is nothing they aren't telling us. NASA and other scientists have told this publicly thousands of times. You apparently haven't been listening.

Answer 4

"Why are they not telling us?"

ARE YOU KIDDING ME?  This information is common...it's simply that average people don't pay attention to science...and they certainly don't like to fund space research.  It's expensive, and time consuming....they would rather bicker about oil than look at the big picture.

Answer 5

So what if there's life outside our galaxy?  Even the closest galaxies are hundreds of thousands of light years away.  The rest range from millions to billions of light years away.  Even light speed isn't enough to make communication with these life forms feasible.

Even within our own galaxy, stars range from 4.3 light years away to nearly 100,000 light years away.  Travelling to or communicating with life forms that far away isn't feasible.

So what if they're there?  There's nothing we can do about it.

Answer 6

What you need to do is investigate the Drake Equation, which is exactly the calculation you're looking for. My connection is very tenuous so I can't look up the specifics at the moment but just wiki "Drake Equation" and you'll get all the information you need on this question.

Answer 7

Look up the Drake equation, then apply it to each galaxy.

This kind of speculation is very old.

What "they" are not telling you is that by now, everyone knows this.

Answer 8

None of this is news (at least, not to many of us that keep up with the world of science).

The probability of intelligent life on other worlds just in our galaxy was formulated years ago (in 1961, its now called the Drake Equation).

Read about it, it includes all the variables that determine the probability of intelligent life - many of the variables are not known, so there are no hard-and-fast numbers to calculate.

The chances of humans like Earthlings on another world are extremely remote - we evolved over billions of years of random genetic mutation and environmental selection.  The chances of those exact same mutations over billions of years producing any lifeform like anything on Earth is infinitesimal.

Life on another world may have similar forms to life on Earth, but not necessarily.  Life elsewhere could be based on other chemistry besides the carbon/water/oxygen chemistry of terrestrial life.

I'm not sure what you think they (whoever "they" might be) are hiding from you.

Answer 9

The problem with life on other worlds is that our sun is the only star stable enough, long enough for life to flourish on Earth, most if not all stars are multiple systems, which would make temperatures on any orbiting planets swing wildly from bitter cold to broiling.

Other stars are too big and unstable to have any kind of life on planets orbiting them.  Some stars can expand to double and triple their size, and their brightness might also increase 100 - 1,000 fold.  Life would simply evaporate.  

Some stars are dwarf stars that sometimes shoot out huge solar flares bigger than our sun.  And some stars are simply glowing embers, emitting light almost in the infra-red.

Our sun is the perfect star.

Answer 10

You have got to check out www.projectcamelot.net

They have interviews with secret x military and nasa employees on things like this and far beyond what you could imagine. Start with Richard Hoaglands interviews first. I think there are like 55 interviews in all and all are great.

Answer 11

I agree with Bruce J.   We are a science illiterate species.   Everyone should know this but I guess they are too busy watching Hulk Hogan or Gene Simmons living their lives on TV rather than learning and living their own lives.  There is not 1500 galaxies in the universe, there are about 350 billion other galaxies in the universe.   In that Hubble deep space view, there are 10,000 galaxies in that spot the size of a dime at 40 feet.   There are that many galaxies in every dime size spot and direction.   If there were only one intelligent species for every galaxy, there would still be 350 billion intelligent species in the universe.

We are probably the only human like species in the universe but no way are we the only intelligent species in the universe.  Just think if the dinosaurs weren't wiped out 65 million years ago.  They would have had another 65 million years of evolution and most likely some kind of dinosaur over that 65 million years would have gained intelligence through evolution.  The biggest mammal around during the dinosaur period was the size of a mouse because anything bigger that that could not hide under ground would have been eaten by a dinosaur.  It was after the dinosaurs demise that the mammals could grow in size and become the dominate animals on Earth.  And no there were no humans when the dinosaurs were here.  The first human like species appeared about 3.5 million years ago and thru evolution of those early species, humans in our present form have been around for about 100,000 years.  

The point is it took evolution 3.5 billion years of different life forms on Earth to finally form humans and we are here only because the dinosaurs didn't make it.  In that case, on another planet, it would be very rare or impossible to have a a species that looked like humans do.   Aliens would probably not look like humans or would be very rare.  

We are now finding that most if not all stars have planetary systems so with that number of stars and planets, there is no way we are the only ones in the universe.  For the number of stars in the whole universe in all the 100's of billions of gallaxies, there are more stars in the universe than the number of individual grains of sand on every beach and desert on the planet Earth.  

There is no way Earth has the only life and an intelligent species.  If we can ever spend more money on our long term survival than we do on our distruction and begin to leave the solar system and colonize the galaxy, we will probably find that the universe is like Star Trek with species that have billions of years more technology than we have, species that have been travelling the galaxy and probably the universe for billions of years.  

Of course most species would probably be immature like us at this time.  They never learned how to live and work together and end up distroying themselves before gaining the technology to travel space.  To travel the universe, a species would have to get the animal instincs out of their systems before they could grow into a more mature species and obtain the knowledge to space travel.  

Remember that the Earth was formed 4.5 billion years ago, which was 9.2 billion years after the universe was formed.   There are probably many intelligent species who's solar systems were formed billions of years before the Sun and Earth even existed.
