Time travel violates causality. The universe does not tolerate contradiction. No time travel.

Re: Physicist believes we will travel through time this century

With some effort we can affect the relative rate at which we travel through time, but we cannot change the direction of travel.

Re: Physicist believes we will travel through time this century

Perhaps one of the greatest arguments against time travel into the past is that we've had no visitors from the future. If we assume time travel were to become commonplace even in a thousand years from now and further assume the human race doesn't self-destruct shortly after getting that far, then there are some thousands maybe even millions of years in which travelers could return to this time. With such high number of visitors someone would mess up and be revealed or their time machine discovered. The only argument qualifying that one is if there is some arbitrary (to us) time limit, say a 20 year window, within which one can return. This would imply that at some threshold time we would be inundated with tourists! As much as I'd like to see life first form in a shallow sea, a T Rex or a Pterodactyl, or even the obvious, the Pyramids being built or even just see them as they were when first completed, shiny white granite with a gold top, if the price is tourists from the future everywhere, count me out.

Bottom line - every year that goes by with no visitors decreases the odds that it ever occurs. So if it is truly physically possible that might imply humans never build it. I hope that does not have ominous overtones for the future of mankind or intelligence.

Time is not the issue. It has no "THing" to change.

The problem is how to handle the matter changes.

Re: Physicist believes we will travel through time this century

I remember from studying pseudoscience many years ago that subatomic particles appear to be capable of time travel. That they do so, or appear to do so, does not mean that atomic structures could do so, or necessarily even that those subatomic particles do so, since our ability to observe is limited. In other words, don't invest too much on those time travel tickets.

Can anybody who really knows physics take a cold shower and tell me if I'm right?

I know I should be excited about this brave new world of physics, but I've been lying in my backyard, watching mesocyclones form, with their turbulence eddies trailing behind, trying to figure out how and why some of those eddies will become killer tornadoes hundreds or thousands of miles from here while most are disappearing before my eyes. Could what I see in those clouds while I'm lying here in the microburst capitol of the world also have larger applications? Could the rapidly changing microclimates here teach us about the macroclimates in a way that would help us preserve all those macroclimates for a few more generations? So many solutions seem possible if only we apply our observations and our dreams to the world that feels like it is almost at our fingertips.

. . . . . . .

Sorry, I get kind of lost in thought, looking at those clouds. Who were we talking about? Let's see, Ronald Mallett . . . . Isn't he Keith's brother? Now there's somebody whose work I've admired for a long time.

Re: Physicist believes we will travel through time this century

Wait!I think I just figured it out!

We ship the genetic code ahead so when those subatomic particles arrive, the assembly instructions will already be there.
