can we possibly send light into the future?

Question

if the closest star takes a little over 4 years to see its light, then could we possibly send light to some other planet billions of lightyears away? like a signal? im not sure how right now, but its an idea

Answer 1

yes. we're sending light out there right now.

by the time it gets there it WILL be in the future

If "they" were looking at us now from a planet 500,000 light yeas away, they would see what we looked like 500,000 years ago. If they moved closer at a fast rate, the less time it would take to get to them. we'd look like we were speeding up.

OR If your talking about OUR future, then we could simply record a message and keep it safe until the future got here.

if we had the technology to build this hypothetical light system , we could theoretically send light out way out to a distant galaxy and loop it around to another and then back to us. Reconstructing it when it gets garbled over distance of course, and then we could send a continuous feed into the future............

one way only though

Answer 2

We can send a message to other planets, and they wouldn't receive it until much later. Although I wouldn't consider that sending things into the future.

There is something similar right here on Earth. If something happens several miles away from you, then you won't hear it until a few seconds after it happens, because it takes the sound waves a few seconds to get to you. Most things aren't loud enough for you to hear them from several miles away, but thunder is. During a thunder storm, you usually see the lightning a few seconds before you hear the thunder, and that's because the light reaches you before the thunder does.

Also note that, rather than visible light, we can and do send radio waves into space. Technically those are light waves too, you just can't see them because their frequency is too low (or too high, I can't remember). So they'd work the same way.

Hi
Scientists trying to achieve sending anything faster than the speed of light is still far from being within the scope of future techology. As far as sending electromagnetic radiation out in to space, we have been sending artificial radiowaves in to space for over sixty years. So if there is intelligent life within sixty light years of earth, and they are listening, then they know we are here. There are hundreds of stars and most likely many times more planets within sixty light years of us. Just something to think about. Hope this helps. Have fun!

well sweetie I think scientists trying to achieve sending anything faster than the speed of light is still far from being within the scope of future techology. As far as sending electromagnetic radiation out in to space, we have been sending artificial radiowaves in to space for over sixty years. So if there is intelligent life within sixty light years of earth, and they are listening, then they know we are here. There are hundreds of stars and most likely many times more planets within sixty light years of us. Just something to think about. Hope this helps. Have fun! -B-

Answer 5

We've been sending radio signals (a form of light) into space for fifty years now. Sometime deliberately in the hopes of contacting other planets, but mostly by accident.

Answer 6

Well what the others said is all true... But according to your idea, what i think you want is that you wanna communicate with other planets billions of light years away.
Well according to the theory, space is like a flexible surface on which all the planets are aligned. But if you can bend it you can move to a diff point in space without traveling in a straight line. Its like bending space and time. Its well explained like this...
If your in the north side of the city and you wanna go to the south. To reach your destination the fastest route, you gotta travel in a straight line, that is using a helicopter of something. But even traveling in that straight line you need to spend time to move to your destination.
Suppose if you could bend your city in space such it folds like a paper and your destination comes above you, you can move UP to reach your destination. This idea is called by many names like warp and stuff... Also explained through black holes and stuff.. But to achieve it in reality you have to have that much speed to slice through space.
Well my point is this, if you can accelerate the photons in light to such an extent then it will be able to rip a hole in time and reach its destination much faster than 1billion years. But such a concept is still in theory....

Answer 7

All the things you can see in the universe are as they were when light left their surfaces, it would be no different for light you send.

Answer 8

I don't think so because the future hasn't happened yet. But it is true that if we looked at other placed very far away we would be seeing their past. Now if only we could get that far away and watch Earth's past......

Given a frictionless ecosystem devoid of different forces recent (like gravity), then it take as plenty power to sluggish something down because it does to speed it up. [interior the case of an area commute or possibly an consumer-friendly re-get admission to pill, that power is wasted as warmth, and to that end the two area commute and re-get admission to pills choose a warmth shelter. devoid of warmth shelter, the two wold deplete like a meteor, for a similar reason.] in reality, that propose that on an prolonged-distance holiday, you need to use one million/2 of your gasoline to begin, and one million/2 of your gasoline to offer up. HOW long it takes to start and quit relies upon on how plenty gasoline is utilized in how plenty time. yet evaluate inertia! in case you used one-one million/2 of your gasoline in one sizable explosion of power, you may attain close to-easy-speed immediately, interior some hours -- yet all your passengers would be smashed to jelly on the rear bulkhead of the cabin! comparable in opposite -- in case you used one million/2 your power to offer up without notice, you will destroy all and sundry against the front bulkhead. [think of like what occurs once you may supply up without notice on your motor vehicle to evade an accident.] SO, you utilize your gasoline allotment SLOWLY, and construct up acceleration to close to-easy-speed. You commute one-one million/2 the gap to the different planet, then you definately change the deliver around and use the different one million/2 of your gasoline to slowly decelerate the deliver to a supply up at your trip spot. yet NOW, you're out of gasoline, and would't return domicile! confident, that DOES take an significant volume of time, and over interstellar distances, the adventure continues to be impossibly too long for a HUMAN lifetime. [Misaligned thrusters are actually not a topic. ALL area ships make "mid course corrections" in the time of their flight, to outlive the right music. yet your speed has no longer something to do with this. it is your DISTANCE on your aim that make the version. Making very small substitute an prolonged way off is plenty extra suitable than making one enormous substitute purely in the previous you land!] action picture star Trek receives around the subject of inertia by utilising an IMAGINARY gadget pronounced as an Inertial Damper. those contraptions "take in" the inertia so as that the action picture star deliver can attain close to-easy-speed virtually rapidly, and sluggish right down to a supply up virtually rapidly. yet no person knows HOW those contraptions artwork because of the fact there is not any SUCH element!

yes, through possible time portals
