Hubble Deep Field Image

[1ViciousGSX]

I don't know if you've seen this before, but it's a pic taken by the Hubble Space Telescope. It is a picture that was taken in a dark spot in the sky as far away as Hubble could see. It makes up a spot about the size of a dime 75 feet away in relation to the surrounding sky. All of those dots are galaxies. Makes us seem really small in the scope of things.

Ya I love astronomy stuff. There was supposed to be a Satellite orbiting saturn by now too if i remember right. Anyone know where you can go to look at it's pictures?

Here you go. The mission is called Cassini-Huygens, named after two signifcant astronomers who helped in identifying Saturn and it's rings. Cassini is the name of the orbiter, and Huygens is the name of the probe that is to be launched and landed on Titan, the largest of Saturn's 31 known moons. Lots of very good information on this site.

I remember when that pic was released, it makes me wonder how some people still believe we are alone in the universe.Even if the odds were 1 in a billion(statistically non existant) that one of those stars had a planet hospitable to life, and on that planet the odds were one in a billion that life could have started, there would be probably a few million civilizations present in the picture alone.

It's amazing how insignificant one photo can make a person feel. Very cool.

[JDM]

I feel small. Makes you wonder when we'll make contact with other living biengs from elsewhere.

And by elsewhere I don't mean Wisconsin.

Joe and Ryan...

[niterydr]

sweeet.
Imagine the 'gearheads' on a different planet...

[Emcee gsxtc]

Now that makes ya just feel like a sack of shit doesnt it? Now I almost dont feel like making any money today, but life goes on. An insignificant spec like me wants to jump in an insignificat spec of a ferrari and travel and travel as close as I can to the speed of sound, since the speed of light is a little of the charts. Crazy hmy:

[Matt D.]

In the BIG picture, even the speed of light isn't that fast. We are hundreds and thousands of light years away from most other celestial bodies, which would mean it would take hundreds and thousands of years to reach them traveling at light speed. If we're ever going to go anywhere outside of our solar system in the future we're going to have to travel faster than light.

Not possible and it never will be.

Technically true, but that doesn't mean there aren't ways around that. While we may never be able to truly travel faster than light, there might be options we haven't considered.

I mean, didn't we all see Contact?

Yeah, and the Earth is flat.

People said for years that breaking the sound barrier in a car was impossible because of the wave created around the car wouldn't be able to form like it does in a plane. It took a while, but they were proven wrong.

Even 60 years ago people didn't think we could get into outer space. Now life would change drastically without and people take it for granted. With our current technology and limited thinking, we cannot think of a way to go faster than light, but that doesn't mean we won't be able to overcome it in the future.

Exceeding the sound barrier and going into space didn't break Einsteins Special Theory of Relativity, reaching the speed of light does.Might I add the special theory of relativity has been proven time after time after time for around 130 years.The Lorentz transformations say(again well proven) mass increases with velocity.At the speed of light, mass is infinite, which would mean an infinite amount of energy would be required to propel something to the speed of light.There isn't an infinite amount of energy in the universe and there never will be.So an object would have to have zero mass or a negative energy density to reach the speed of light.

I agree, there are a plenty of ways that will eventually allow us to travel unimaginably large distances.Quantum worm holes and the Casimir effect have the greatest potential IMO.

The special theory of relativity applies locally, but we do not know how it applies on a greater scale. We do not have a firm grasp on how space and time are related and the theory applies only to a spacetime area that is flat. Just like a circle, if you take an area small enough it is nearly flat (a tangent), but when you look at a larger area it is curved.

Spacetime may be just like this, but we do not know. Jumping between those points may make it appear to other observers that you are traveling faster than the speed of light. The Alcubierre warp bubble is a theory about this. There are tons of other theories too, but our knowledge is so limited on the subject that it is all speculation right now.

I know the answer.. and if i told you they would keel you...

General relativity tells us how it acts on a large scale, which has been proven over and over again for 75+ years.We do have a grasp on how space and time are related, and we do know space and time are warped by energy/mass.It can be observed in some of the gravitational lense pictures at the above Hubble link.

As far as taking a short cut through an area of warped space-time, even though it would appear c is exceeded, its not.The object taking the short cut is still travelling less than c, Alcubierre's "theory" even states that.Its analogous to 2 cars travelling from one side of a mountain to the other.If a car dvives over a mountain and a car drives through a tunnel in the mountain both traveling at the same speed, the car going through the tunnel will arrive at the other side before the other car, but the speed is still the same.

[JET]

Yeah, and I stated that it will appear that c will be exceeded, in what I said. Also, I don't know if you know or not, but c has been exceeded. It just has not been exceeded by anything with mass.

Also, Einstein's theory has not been proven on a grand scale. We are stuck on this tiny speck of sand in the universe. Things may be different on a larger scale.

Hell, for all we know we will end up being able to convert ourselves into pure energy, in which case we would have no mass and be able to travel past the speed of light.

No proof exists that c has been exceeded.I have read about experiments over the years in which scientists have supposedly accelerated photons faster than c.In these cases it still only "appears" c has been exceed, but its more than likely other things, like quantum tunneling, that are actually happening.

Also, Einstein's theory has not been proven on a grand scale. We are stuck on this tiny speck of sand in the universe. Things may be different on a larger scale.

Gravitational lenses billions of light years away, blackholes, and the perihelion shift of Mercury have all been observed and accurately predicted by relativity.I don't know of a more grand scale than that.Its actually the extremely tiny small scales where relativity breaks down, which is where quantum mechanics come into play.
