Going the Speed of Light

[OneKube]

If you're traveling at the speed of light you see that time is stopped.. like if you go 40 light years and look back you see the past. Anyway if you doing the speed of light you see time stopped but really it is still going, because it is taking time for you traveling the speed of light. Sorry I was discussing this with someone.

(This is how I understand)

If someone on earth were watching a spacecraft travel at the speed of light, the travelers time would appear to be passing slower, than them.

However, from the travelers point of view, the time is passing the same for them. (It's kinda hard to explain it)

But I do know this, We could never travel at the speed of light. maybe close to it like 99.99999999% but never truly 100%. Just like absolute zero.

Now I thought a while ago about this kind of thing, that if I toss a ball in the air away from me, and you go the speed of light to go catch it, you would miss it because you are going slow relative to me. it would take you years to get there. but a little later i thought, you would only have to go the speed of light for like a nano second, so you would catch it.

Sorry I was disguising this with someone.

You mean Discussing it with some one else

I think its just like cubing (I hope you don't mind me mentioning cubes in this thread) Where you do a cube really fast and you think time is still going but when you look at it it has only past a few seconds or minutes.

This raises another question of mine:

When moving faster than the speed of sound, can you hear anything? I doubt it, but I've never done it, so I have no idea.

 

[brunson]

Yes. Otherwise fighter pilots couldn't use their radios at supersonic speeds. With all these questions, whether speed of light or speed of sound, it's the locality of reference. The air in the cockpit is not moving in relation to the pilot, therefore sound propagates normally within the local frame of reference. The earth is moving thousands of miles per second, but within it's local frame of reference, sound propagates normally.

I hate this thing where people think going the speed of light affects time. Here's what happens when you go the speed of light.

1. You would have no shadow because light doesn't get to you.

2. It would be very, if not pitch black where you are running because light can't reach you.

3. You will hear nothing because you are going much faster then the sound barrier. (however though it would probably burst a humans eardrums)

4. Even if you did manage to "spin earth the other way" you wouldn't effect time itself, oh yeah, you would also probably cause a few major earth quakes to because of the earth shifting, but you would never be able to shift the earth because the wind force necessary would be extremely immense and would never be achievable by any living thing. If you go the speed of light to catch a ball you would get the in a matter of milli.(much much smaller though)seconds. It would not take forever. If a space craft was going the speed of light you would not see them because the human eye can only take a certain amount of pictures per second. Even a high-speed camera couldn't even pick it up. Now if this craft was 1 billion miles long and a little farther then the sun and high speed camer might be able to pick it up.

:fp You dont understand relativity. Lrn2physics.

Its called time dilation, time is slowed when you travel at very high speeds, or in the presence of immense gravity.

 

[xXdaveXsuperstarXx]

time is slowed when you travel at very high speeds, or in the presence of immense gravity.

So if what you say is true, why can't we see rays of light in the air on earth?

Then the rays must still be going too fast for us to see? So it is still going very fast.

Instead of trying to save face and making fallacies, you should take a physics class or perhaps use a wiki.

[xXdaveXsuperstarXx]

Wait, what are we trying to prove? I got kind of lost on that.

EDIT:

Okay, so you would go slower because of relatively or whatever you call it. But if you were going the speed of light you would simply slow down. But I do not believe that you would change time, for you are not going at the same speed as the speed of light because it would slow you down. Either if I'm right or wrong. I firmly believe that it is impossible to change time or slow down time. I believe that time happens as it is. It is not something that we can control.

Im disproving your fallacy.

 

[xXdaveXsuperstarXx]

Well, I don't believe it changes time because I'm using logic . If you were in a craft going the speed of light you would experience time like other people, you are just experiencing it at a different speed then most. However if it were real the G-Force would probably rip you skin off. So, this would never happen.

 

[Tim Reynolds]

Stop guessing about what life would be like if you were going the speed of light.

It's not possible. That's a basic fact of relativity.

 

[xXdaveXsuperstarXx]

We know it's not possible we're just doing a hypothetical conversation. Now if this were based in space it would be physically possible because there's no gravity.

 

[4Chan]

Ughhh, your logic is flawed, because you're not basing your assumptions on FACTS. (i.e. Einsteins relativity.)

1. Only light can travel at the speed of light because of its mass (or lack thereof).

2. Stop trying to avoid the proven fact that time is dilated in the presence of gravity and speed.

:fp
It wouldn't seem that moving faster would slow down time, but it does. There isn't really a reason behind it's just the way it is. Basically, If two objects are moving towards each other you can use the equation velocity1 + velocity 2 to find how fast they are moving to each other. As things turn out, this equation is near accurate at low speeds but when you use speeds extremely fast - the speed of light - time slows down exponentially. This can be proven by a simple experiment, if there was a source of light on one end of a table and something to measure the lights speed on the other end, if you were to measure the speed of the light you would find the speed of light, of course, but if you were to put the light source on wheels and pushed it towards the thing measuring the speed of the light, you would still get the speed of light. This is because the speed of light can not be exceeded. So if two photons of light were moving towards each other they would be moving at each other at not twice the speed of light, but the speed of light. This was one of Einstein's largest breakthroughs because he changed everything the we hold to be true, and thus redefined all of physics.

I have no formal education on this topic, but all of the knowledge from this post was taken from this college lecture. If you are interested in understanding relativity more thoroughly check it out.

[xXdaveXsuperstarXx]

Okay, so if it goes slower, it goes slower or is it that it goes slower but it doesn't. Or is it just that we have a flawed way of measuring time? I really don't get it.

What exactly are you trying to argue?


If you could travel on a light wave from the sun to the earth, how long would it take you?

 

[xXdaveXsuperstarXx]

If you could travel on a light wave from the sun to the earth, how long would it take you?

8 minutes (maybe 7, I don't remember). So your trying to say that the light itself takes 8 minutes. But if your on the light it's much slower?
