patently aware of the speed of light, what it is and how it has been treated as a unproven constant

Of course, it's possible scientists are currently wrong, but there is no evidence of anything travelling faster than light so far.

scientists have been wrong for a long time, how do you observe things which travel faster then your data collection abilitys ?

Yea I'm one to think this thread is just irrelevant until further information is found. You guys think the technology field is constantly changing and full of controversy? Try theoretical physics.

Sorry to jump in here but I have a stupid question that just burns in my brain regarding this time dilation etc stuff, mainly directed at lordikon, and others in the know regarding physics.

You say a few pages back about the 4 year travel to alpha at near the speed of light, saying that the traveler would experience 4 days, yet earth would experience 4 years...

My question is regarding the aging part... Are you telling me that the cells/organs/whatever in the bodies of the travelers would only age 4 days, while the bodies of those on earth would age 4 years... So expanding the example, say we take a trip near the speed of light and experience 40 days of travel, 20 days there and 20 days back to earth... When we arrive on earth will the travelers look 40 days older (so not noticeably older) and would the people on earth look 40 years older (grey hair, deaths, births, childhoods, etc included)?

That's what I don't get lol.

I've yet to see any evidence that photons have mass (rest mass). It's not known for sure that they're absolutely massless, but if there aren't then there would be issues with the math.

http://en.wikipedia.org/wiki/Photon#Experimental_checks_on_photon_mass

E=mc^2 is a scientific theory, not an "assumption". There's a huge difference, as a scientific theory, in this case, has thousands of predictions that it has gotten correct and many attempts to verify it have all proven correct. Light is actually a proven constant thus far, unless you have some evidence to the contrary.

I'm open to the things you're talking about, if you're willing to provide some evidence.

Yes, the cells and atoms in the bodies of the travelers would only age a few days while the people on Earth's would age 4+ years. The things that cause aging (and the passage of time) would actually slow down. If you and a friend were 20 years old and you left on a near speed of light round trip for 40 days (for the travelers), when you got back to Earth your friend would see you as 20 years and 40 days old, and your friend would be 60 years and 0 days old.

Mind blown... That just crazy insane, not doubting you since I ain't no scientist but damn...

You know, I think I'll say it again. You guys can argue all day, but this is the kind of stuff that so so close to the forefront of human understanding that much of the information is subject to change at any time, and also that there are divisions among leading yet disagreeing bodies of study who are doing work right now that can render anything said here a pointless argument. Just a heads up.

The stuff I'm talking about have been known for 100 years now, thus far nothing has proven it wrong. I wouldn't say everything about special relativity is "up in the air" or could change at any time. That's like saying Newtonian physics might be way off and could be changed at any time.

This would, in theory be a good thing if time travel affects only the person changing the results and everyone else retains a normal timeline, maybe creating an alternate dimension for his altered timeline which he returns to and us, having no affect being in the original dimension from whence he came. I just love time travel, and the headaches it gives. biggrin.gif

The beauty industry should get behind this then lol. Find why speed creates anti aging then bottle it haha.

Yea Newtonian Physics isn't way off, but the problem of looking at it that way is that (if I may use a metaphor) Newtonian is more of a rough sketch, when we could compare what we know today as more of a photograph.

Yes Relativity has been around for 100 years, but the fact that it may be built upon may render parts of it "obsolete."

One thing I will point out is how Relativity still has problems meshing with Quantum theory. So I am just led to believe that it (and/or quantum theory) are not complete pictures of the reality. So this would imply that there is the possibility of change, particularly at any notice because it is one of the main drives of theoretical physics today to attempt to solve this very problem I am talking about.
