So presumably you are saying that, when we can, we should venture into the cosmos as peaceful ambassadors rather than warlike Klingons?


Of course!

I think I can accept that as a basis for future human evolvement. But we have enough strife back here at home, gawd knows what it may be like out there in the "REAL WORLD"


True. Maybe it's for the best we don't know everything...


Oh I'm not disputing our limits at this time but what I put across to the teacher if we could or right at the speed of light. Has got to be something different. It would be nice to know if it's true or not. Maybe I'm just spinning my wheels but thank you for your comments.
Cheers everybody

We do not have to "obey" the laws of physics, we grudgingly accept them as they unfortunately are, but we should be finding ways around these constraints that are holding the human race back from fulfilling it's full destiny.
It would not be finding a way around the laws of physics but using laws we don't yet understand. If there are not exact unchanging laws that means all being is at the whim of a capricious and arbitrary force.



How can we be using laws we don't yet understand?

Nothing can go faster than the speed of light, a law of physics.

The universe is 13.6 billion or so years old yet it is 93 billion light years in diameter. Hummmmm? Ignorance of the law is no excuse. It appears physics is like a country and we are only subject to the laws of the country we inhabit.

all well and good but i popped a hypothetical question, was I wrong? From the guy who got a "C"

There's one universal language, maths, maths is VERY much needed in fyzix. We're just not ready to 'understand' the whole picture is what I think (probably cause my math stinks)

You assume that the universe was in the universe at the time of the big bang. Benny Hill teaches us never to "assume"

Assumptions are the worst... (in maths that is)

[edit]Assumptions are the best. (in Humanities that is)

Cosmology is actually just on the edge of assumptions and truth

We can't find the truth! Argh!

[edit] Assumptions have lead to truth sometimes though. Let's remember Plato, and Socrates! Or the Quoran for that matter...

If an assumption is a jumping-off point to further understanding and questioning, it can't be a bad thing. Of course it could be a wild leap straight over a cliff - but even then there'd be a lot you could learn as you plummet down it... like how reliable gravity and the electromagnetic force is. I know for a fact :) that my brain works much faster than the speed of light :) by the rate at which it goes from understanding something to well... not understanding anything at all :)

That is philosophy, philosophers know they are only philosophizing. Religious books that claim to be the word of god are something quite different.

One's Autonomic nervous system is even faster than that. It can't wait for thought.

Ooh :) didn't you just ask me that Julie? Must be deja vus.

Liked that bit a lot, Chris - and the pictures were pretty too - interesting link thank you - of course they were talking about the speed of intelligent thought - whereas I was talking about my personal "bafflement" speed of collapsed intelligence - very different thing - and happens very fast indeed :)

But even if we could reach the speed of light and you shine it straight foreword it can't be seen.

like an SR-71 or a have blue if it have guns it would out run the bullets. it would make a very nasty day at work.

Hello, I'm new here. In the field of Satellite Communications (and many others) we would measure time using atomic clocks. You could learn more at wikipedia's atomic clock page

This method of timing is used in space exploration as far as I am aware, and is our most accurate method of keeping time. You could keep time in any manner you wish, because your definition of what time it is, is relative. For instance time in the Pacific is different from time on the east coast, but really... the same "time" has passed for both geographic locations.

Hi Caleb, I have a grandson with that name.
we agree that time seems to be sound at this day and age but we are so young yet. loop holes might be there we don't know. but my question was if i hit the speed of light would the light foreword stop? Hard call ? and if could go faster would the light bend back? Crazy question.
Cheers everybody
