Not really, except with black holes I think (some paradoxial stuff).

Another way is for you to break the light barrier and see some future echoes...

space is very interesting. isnt it broken up into three parts though? past present and future? isnt thats how they can look to see what happend to the universe formed? light years or something?

I don't think it's broken down into parts as such.

As far as I know it is just a perceptive thing.

For example, our nearest star (other than the sun) is Proxima Centauri of Alpha Centauri which is 4.24 light years away, which means even if we could travel at the speed of light it would still take us over 4 years to reach it.

Now, if we look up at the night sky to see the light of the star, we are looking back into the past. This is because the light we are seeing has taken over 4 years to reach us. At that moment in time, the planet might have ceased to exist, but we would still see it, we would have to wait another 4 years to see the light from the star diminish.

The Universe is an enormous place, it is that big it takes light 78 billion years to cross from one side to the other. So even if you could travel at the speed of light, which is theoretically impossible, it would still take 78 billion years to travel across it. When the Hubble Space Telescope is used and it looks at the our nearest galaxy which is the Sagittarius Dwarf Elliptical Galaxy which is 80,000 light years away, it is looking into the past 80,000 years. The Hubble Space Telescope ultra-deep field can see very far into the Universe, it can see so far the light it sees left its source billions of years ago.

Anyone seen the square nebula?

Have now thanks, very interesting

From Space.com:

Quote:

“If you fold things across the principle diagonal axis, you get an almost perfect reflection symmetry,” said study leader Peter Tuthill from the University of Sydney in Australia. “This makes the Red Square nebula the most symmetrical object of comparable complexity ever imaged.” The Red Square’s extreme symmetry suggests the star’s surroundings are extremely still and not buffeted by external stellar winds or other turbulence...

The new findings suggest the system’s perfect form results from an even outflow of gas. “The reason the Red Square remains so symmetrical is that there is no material that has interfered with the outflow, so it has preserved the symmetry it was born with,” (said researcher James Lloyd of Cornell University).

There is a picture over at the National Geographic Website

Actually Telescopes are time machines

The universe has more than one billion of galaxies, our galaxy has about 200-400 billions of stars.
From all these stars there is a great number of stars who are exactly like our sun, if a great number of those have planets orbiting around them, a big chance there is life.

So yes, there must be life out there, I agree that we are not alone, however I am agnostic when it comes to the claims that we are being visited by aliens, dispite the fact of being a startrek fan.

lol You're supposed to drink it, not put it in your eyes. :roll:

The universe didn't make alcohol, mankind did. I agree though, alcohol is evil, it is the worst drug on the planet, together with tobacco. It's not so much the fact that things are discovered, that is science. It is how it is regulated that is the problem and that is the law.

The problem with alcohol is if you have a couple of drinks it is ok, it is euphoric, but then anymore than that and it is stupifying, it is responsible for large amounts of violence and crime in our country. I don't drink alcohol. I'm sure a few people have woke up in a police cell heading for prison and not even being able to remember why, now that is evil.

Lets not even talk about tobacco, it is as addictive as Heroin, it's just you don't have the same terrible withdrawal issues.

The goverment make billions in taxes from selling the public poisons. Self-control or abstention is required, because the law is unbalanced, especially when given other substances like Cannabis are illegal, it is a mockery.

Of course, I have always loved space and planets etc...but sometimes I get so into the concepts that it does my whole head in.

When I was little I remember thinking but what if we are all just germs on a tennis ball in somebody's cupboard???

lol I used to think that too when I was told once that the form of a star system resembles the form of an atom, and thinking what if the solar system is an atom of a large object or organism.
