Title: Is it really impossible to travel faster than light?
Post by: Railton2 on 02/06/2010 18:35:29
Hey!

I'm not sure if this thread is in the right forum or what. If not, will you please move it to the right forum please? :D
I also want to tell you that this is only a thought. Not any scientific prove.
I am only seventeen years old, and I am going in 10th grade, so I don't have any education in science/physics. So please don't call me a crazy scientist, even though how crazy these things sound. I am only posting this to get some answers on my speculations :P




Is it really impossible to travel faster than light?


In order to make matter escape from the event horizon at a black hole, then the matter MUST have a speed faster than light.

A black hole is an area in space, so dense with matter, that the gravitational field is so intense that not even light can escape.

If all matter and energy was created at the same time as big bang. Then there MUST have been a black hole a few planck seconds after the big bang, since all the matter in our universe was so dense at that time.

Doesn't that mean that all the matter in our universe was in the event horizon, at a black hole, at that time?
Why didn't all the matter crumple into the singularity?
How did all the matter escape with a speed slower than light?





I also have an other strange thing, that I need an answer too. I'm really bad at explaining, that's why it's so long, sorry :(


Lets say it's possible to travel with 99,9% of the speed of light. Accordingly to Einstein's theory of relativity it isn't possible to exceed the speed of light. But it also tells us that if we move at a speed 99,9% of light, then the time almost stops.

Lets imagine that I travel with a spacecraft that could reach that high speed and flew only for a second. Wouldn't the time on earth go faster compared to the second I travelled with my spacecraft?

For me, my travel would only take one second. But if time goes slower at that speed, wouldn't the earth's time then go faster?

If the time on earth goes faster than the time in my spacecraft. Wouldn't it then look like - watching from earth - I have used more than one second to travel that distance?


Lets say we have a set a timer, that starts when I take off. One timer on earth and one timer on my spacecraft.
If I take off with the speed 99,9% of light and stop exactly when my timer says one second. What time would the timer on earth then be?
Wouldn't it be more than one second, as the time on earth goes faster?

If it is more than one second. Lets say two in this example. Then looking from earth it would have looked liked, I have travelled the same distance in two seconds. But I have really travelled the distance at the speed 99,9% of light. But according to the timer on earth it only looks like I have travelled with half the speed.
Lets say I travelled 300.000 km in this example.
According to the timer on the spacecraft it must say that I have used a speed of 300.000 km/s (lights speed) because 300.000/1 = 300.000.
But according to the timer on earth it must say that I have used a speed of 150.000 km/s (half of lights speed) because 300.000/2 = 150.000

Doesn't that mean, that I need to travel faster with my spacecraft to reach the speed of light, looking from the sight of earths time?

Is light really travelling with 300.000 km/s or is it an illusion that looks like it travels with 300.000 km/s, but actually is much more faster?




Thanks for reading and I really hope you understand and can answer my questions.

Sincerely,
Mark Railton
