People. Do you think that NASA is working on some kind of engine that alows you travel with speed of light or higher. Also i head that coal-oil or fuel or oil how ever you call it just left for 20 something years. That means NASA is starting to work on core reactors to power the ship and engines. So do you people think that some kind of technology will come out during this century ?

Of course not...


Final question was "in this century" in this century is 100 years. Also in swidcherland they are allready testing with black hole technology. That thing is certainly almoust same as light travel thing. It just drains too mutch energy. Try wikipedia it says same.

Yeah yeah... science fail and lie really much times, i do not believe we're going to other galaxies in this century (which would be obviously possible with light-speed).
Go watch some more Star Wars and let science start thinking on that...

What the..... I have never watched sutch a movies i hate them. It is my own interest. I was reading tons of books i am interested in this and i want to see opinion of other people.

Please try to stay in topic and dont offend me.

The closest galaxy sits at 25000 light years from Earth, which means that if we can travel near the speed of light, it would still take us 25000 years to get there, and another 25000 years for either the vehicle or the message that we had arrived to come back to earth.

speed of light in empty space can't be exceeded, at least it is VERY unlikely, because modern physics base much on that fact.

Accelerating an object (spaceship) to that velocity would require way too much energy.
Also particles would make a short work of your ship at higher speeds when you collide with them.

Let's be honest. We're never going to get out of our solar system

Well, physically, an object can't reach speed of light. It can reach like 99.99% of light speed, but not 100%. Unless somebody invents warp drive

Wormholes & parallel universes to the rescue!

NASA does not use coal or oil as fuel, it uses special mixtures (solid, liquid, gas or gel), usually different fuels in different stages of the rocket. There are also ion engines, which run on magnets (and electricity).

There is no currently known fuel with a high enough energy to mass ratio to be able to get something moving near light speed (when travelling close to light speed, your weight will increase significantly to almost infinity).

I do wonder what would happen to time at such high speeds. Would you be able to live for hundreds of thousands of years at 99% of light speed?

I dont think WE will ever get to another galaxy in this or any near-by century since Earth doesnt have enough resources to power up a object/rocket to the speed of light.

PS
Image what would of hapen if 90%of the rocket is going a bit slower then the rest of the ship (i think [BOOM]) Well its my opinion

Whats the speed of darkness ?

Do you mean speed of whatever is in the void? technically there is nothing but they say universe is expanding so in theory "nothing" might have some sort of speed. where the new space comes i dont know, possibly everywhere. my logic says that everything is moving in every possible direction with unknown speed, while staying still.
Wait. it doesn't make any sense

Yea i your totaly right i mean there isnt a wall out there
there is just space and just take 2 minutes to think abut INFINITE SPACE which is every second growing and expanding !

PS
Our brains (human brain) are totaly stupid to think about stuff like this, example of God which wasnt born or created (NOW THINK ABOUT THIS) our brains are totaly (Searching word on google) narrow minded and thinkinh "outside the box" stops us from advancing in any direction!!! Think about how people invented all of THIS they surrely had a spark of a bigger brain or luck...

PSS
No one can be sure that space is infinite as earth was 1000 of years ago or the space expansion thing since you can NEVER profe something is infinite !

how do you think something bigger than light [...]

Oh my god... darkness doesn't have it's own speed, darkness is the absence of light.
And light doesn't have mass, so nothing can't be bigger or smaller than it.


user A Mad Bro has written
the universe avtually can't be infinite cause it still expands.

I wonder what happens if you reach the "end" of the universe... maybe a critical error+engine crash?

Light is both particular and energetic.
The universe is finite, but expanding, faster than the speed of light.
This can happen because it is 'nothing', and 'nothing' can travel faster than the speed of light
Lee is right. The speed of light is still pathetically slow for our pathetic lifetime. There are theoretically other ways to get to a place faster than traveling the speed of light directly there, by taking 'shortcuts' (Such as the folding of space.)
Are we going to be able to do this within the next hundred years?
If we're on our own: no. Even 'not extinct' in a hundred years time is questionable.
If, on the other hand, another space-faring species came to us, with whatever technology needed to travel large distances in short times, there is a marginal chance they might help us meaningless creatures. However, that combined with the sadly slim (as all hell) chance that they would even stop by Earth, it's not really a considerable factor.
Is it possible to travel a lightyear in a month (Or less)?
This is perfectly theoretical and hypothetical, but my personal bet is on 'yes'.
Will we ever be able to travel a lightyear in a month (Or less)?
If we survive long enough, we might be able to find a way. Survival is tricky, however, with what we're pumping into and around the planet, in the loons we're putting in charge of the world we do not own.
Is NASA doing any res-...
No.
Well, if we are able to sometime reach beyond our quaint little block in the universe, will we find other creatures?
It's highly likely. The immense amount of galaxies, each containing a breathtaking amount of stars, each of which could have multiple worlds, leads me to believe that the mistake of life could easily have happened many, many times throughout the universe.

It always amazes me how the seven billion of us collectively are so ignorant as to the smallest percentage of the universe's knowledge. Don't take this personally. It's me, you, old Al. Einy, the whole race (Though, with humans, it's pretty much a snail's race.)

Some years ago we thought that the earth was a disk. When the trains were invented, they thought that it's dangerous for humans to travel faster then 30km/h (18,64 miles per hour) because it would destroy their sense of orientation. After that, humans thought that it was impossible to travel faster than the speed of sound. Now airplanes travel faster than the speed of sound. I don't think it's actually impossible to travel faster than light. Physics try to prove me wrong, but physics was wrong so often. It's always just a try to get as near as possible to the truth, but you will never reach it. Perhaps travelling faster than light is impossible in our dimension. But perhaps we can invent an engine which travels faster than light in another one?

If you start traveling at the speed of light the physics will slow you down more. The more you are slowed down the slower time moves for you. But when you travel around an hr under lightspeed you will be in the future.
