- peterjmag, on 01/03/2009, -7/+255Light takes a certain amount of time to cover a certain distance?! No way! What our eyes perceive is not actually occurring in that exact instant?! Oh my god! Light can reflect off of things?! ... You get the point.
- Kosh, on 01/04/2009, -2/+146Buried for dupe, THIS WAS ON DIGG TOMORROW.
- falkyr11, on 01/03/2009, -1/+105Misleading headline. To "travel," one must actually move from one place in time or space to another. This article asserts astronomers "travel" in time by looking at past events through their telescopes. I guess I also travel in time every time I watch a rerun of "Leave it to Beaver."
- trezegol, on 01/03/2009, -1/+85well... in a sense... while I stay 5 hours clicking away on the PC, time passes around me... so I guess I'm a time traveler too :P
- HankHill00, on 01/04/2009, -6/+7022000 Diggs in three months, eh. Power-user much?
- wafflez, on 01/04/2009, -2/+64The headline was meant to attract idiots >_>
- ryan83189, on 01/04/2009, -0/+51We are all traveling through time, linearly, at 1x speed.
- a1cd, on 01/04/2009, -1/+36He just travels forward in time and sees what the popular articles are gonna be.
- lordwow, on 01/04/2009, -1/+33Going back in time sounds great, but then you get trapped in the past, leaping from life to life. Trying to put right what once went wrong. And hoping each time your next leap... is your leap home.
It's not all it's cracked up to be. - Bloake, on 01/03/2009, -1/+30Wow. This is not new. I learned this in high school.
- KevenM, on 01/04/2009, -0/+28Holy misleading title Batman!
- cwilsons, on 01/04/2009, -3/+29I don't see any reason why that wouldn't be true in theory.
- Chris_F, on 01/04/2009, -0/+20In a sense, this title was misleading. Tell me something I don't already know.
This article has no relevance to time travel at all. - ddgromit, on 01/04/2009, -0/+19you are dumb.
- monkeyrun, on 01/04/2009, -1/+19if that is "time traveling", then looking into the mirror is either "cloning" or "teleportation".....
- utnow, on 01/04/2009, -1/+19The answer is yes. If there was a mirror in space, and we could see the reflection... we would be looking at the past compared to that instant.
Confusion results from people thinking about looking back at the time of the pyramids... and assuming that we were the ones placing the mirror there in the first place.
Even if we put it there, we would still be looking at the past... compared to the moment of looking. - AlxRymnd914, on 01/04/2009, -3/+18So if there was a huge mirror way out in space and there was some telescope to look that far into space, we could look at earth in the past???
- ScientistBlah, on 01/04/2009, -0/+14Look up in the sky! It's a bird! It's a plane! It's the joke!
- Kosh, on 01/04/2009, -0/+13I meant what I said
- oboshoe, on 01/04/2009, -0/+13oh boy.
- inactive, on 01/04/2009, -3/+16Yep. That mirror would have to be 200 light years away for us to see the pilgrims sitting down at the first thanksgiving... assuming we had a telescope that could find an image 400 light years in front of it and see it with such resolution that we COULD actually look at a "google maps" version of pilgrim villages... Also the pilgrims would have to have installed it using a ship that could travel at light speed and was able to sustain a crew up into the early 19th century when it would finally arrive at it's destination... although to them it would still be the day they took off as they've been traveling at light speed for 200 years. Oh sure, they'd all be dead, what with being 200 years old and everything, but technically their calendar wouldn't have changed since their launch date.
But of course, if we could do that we'd be able to find another civilization and intelligent life and perhaps they had a way of just jumping through the fabric of time and space, rendering the pilgrim's sacrifice obsolete and depressing. - bongfarmer, on 01/03/2009, -2/+14You can vary the speed of time by varying the force of gravity on an object. On a tall mountain time goes slightly faster than on sealevel
But I guess thats more just hopping on a different bus thats traveling at a slightly different speed on the same road that we're all on than real time travel - Phazoni, on 01/04/2009, -0/+11Buried for misleading and idiotic title.
- notzak, on 01/04/2009, -5/+16In a sense, Astronomers are dicks.
- ldailey06, on 01/04/2009, -1/+12Technically everything you see is 'in the past', light has a finite velocity.
- danvi, on 01/04/2009, -1/+10You are seeing a 'younger' you, when looking in the mirror
- DaltonZ, on 01/04/2009, -0/+9Actually, no, we couldn't see anything further back than the moment the mirror was placed. For us to be seeing the pilgrims, we would have to transport the mirror faster than the speed of light out past the light that reflected off of the earth when the pilgrims were here.
If we were to place a mirror into space right now, making it magically appear one light year from earth, it would take a year for us to be able to see the mirror in the first place, and we would then see ourselves back when the mirror was magically poofed into space the previous year.
If the mirror were flown into space and we watched what was being reflected, well, I dunno. - wonderchemist, on 01/03/2009, -0/+8And if you have a few atomic clocks handy, you can prove it to yourself on your next vacation like this guy.
http://ptonline.aip.org/journals/doc/PHTOAD-ft/vol ... - PabloMac, on 01/04/2009, -0/+8I learned all this stuff over twenty years from now.
- Dumbledorito, on 01/04/2009, -0/+8This sounds like something a scientist tells a young boy in a cheesy 50's sci-fi movie. Sure, it's correct, but it's the astronomical equivalent of saying that watching a Jackie Gleason DvD is the equivalent of opening a window into the the past or seeing the dead come back to life.
- Myztry, on 01/04/2009, -1/+9A crystalline surface could provide such a mirror allowing to reflect light from a past time.
Unfortunately we would be lucky to get a single photon back.
Even the slightest variance of angle over such distances would require an amazing capture area even if the reflection surface was at an absolute tangent to the viewer.
Plus everything moves. Even a perfect laser that rebounded to the exact same spot would not be seen, as the Earth would undoubtably be in a different location by that time. - FKnight, on 01/04/2009, -1/+9What's cool about this story is that they can't directly see the Supernova occur because the explosion subsided centuries ago, yet they can still watch it happen via it's reflection elsewhere.
I can't recall off the top of my head, but I believe there was a science fiction novel based on the idea that humanity figured out how to open wormholes to any point in space and observe the Earth through them, thus being able to observe the Earth during any desired time period.
I think it would be cool as hell to find a light echo of our Solar System that allows us to see it as it appeared years or centuries ago.
And since I'm here -- can someone explain to my why in Google Chrome I'm sitting here trying to type this comment in a comment box which is bouncing up and down more than a pogo stick? I'm about to have a seizure.
EDIT: YAY!! I was able to click the "Save Comment" button even though it's bouncing up and down. - ebcreasoner, on 01/04/2009, -0/+8Soooo you could kill them?
- postitnote, on 01/04/2009, -0/+8Primer
http://www.imdb.com/title/tt0390384/ - inactive, on 01/04/2009, -2/+9Yep you can also tell because its a ***** spam article for idiots
- ikeeel4money, on 01/04/2009, -1/+8does that mean you are one too?
- Chris_F, on 01/04/2009, -2/+8In theory, yes. But that would require some incredibly large and incredibly perfect mirror in the right place, and an incredibly powerful telescope, so it wouldn't happen.
- inactive, on 01/04/2009, -1/+7Time travel is the easy part, its finding the DeLorean that is difficult
- PhantomPhoenix, on 01/04/2009, -0/+6Uh...this isn't news. News has to be something new and/or relevant. This is like something you'd learn off-topic from your sixth grade teacher then more in-depth from your high school physics class.
- mfhayes, on 01/04/2009, -0/+6"Nothing you see right now belongs on your now-list, because it takes time for light to reach your eyes. Anything you see right now has already happened. If you look across the Grand Canyon, you are seeing the other side as it was about one ten-thousandth of a second ago; for the sun, you see it as it was about eight minutes ago; for stars... you see them as they were from roughly a few years ago to 10,000 years ago. Curiously, then, although a mental freeze-frame image captures our sense of reality, our intuitive sense of "what's out there," it consists of events that we can't experience, or affect, or even record right now."
-Brian Greene - jake1337, on 01/04/2009, -1/+7Light takes time to travel long distances?? Holy ***** thanks for update retards!
- 350Zed, on 01/04/2009, -1/+7Watts != Hertz
Humor fail - FlyingCaveman, on 01/04/2009, -0/+6Skeptical Digg Reader Says Astronomer Smokes Pot All The Time.
- PabloMac, on 01/04/2009, -1/+6Time Bandits. Skip it.
- inactive, on 01/04/2009, -2/+7Think about it like this: we are all moving through time at the speed of light.
Just take a minute to think about that.
Also, gravity changes time. Technically, your feet pass through time at a slower rate than your head because they are closer to the Earth. Astronomers measured gravity's effect on time by sending radio signals past the sun, as the signals passed the sun they slowed down significantly before returning to normal speed. - qxrt, on 01/04/2009, -0/+5Dude, everyone is time-traveling. I mean, I'm typing this second sentence a few seconds after the first one. I must be a time-traveler!
- Hetman, on 01/04/2009, -2/+7Not everyone. Astronauts and pilots can actually are traveling through time a little slower than the rest of us. Not that we can tell or it really matters but it does illustrate Einsteins theory of relativity.
- GeezerD, on 01/04/2009, -0/+5I can travel back in mental time to when I actually thought this article might turn out be worth reading.
- loggedout, on 01/04/2009, -0/+5we'll be able to see your explosion's light in a few years.
- 2of8, on 01/04/2009, -0/+4Is there anybody who does *not* know this?
