Yeah. Unless you had something to act as a reference point that your spatial coordinates would be based on the fact that the earth itself is constantly moving would be a big problem. And making a reference point compatible with the technology would probably be impossible until the tech is at the very least near complete, so if it's possible this could create a hard limit on how far back you can go to be at around the same time as the technology comes into being
Time travel being possible inevitably leads to people traveling back in time until there is a timeline in which time travel is never discovered.
Future is definitely a thing. A lot of things effect the passage of time, or rather the perception and effect of it and they're all within our power to technically control (With travel), but also not worth the extraordinary effort.
It's possible! But humanity ceases to exist way before they can discover it since we are doomed fucks who will always put profit before anything.
I can prove forward time travel is a thing. You'll be in the future by the time you're done reading this post. See, I'm correct, compared to where you were in time when you started reading this post you are now in the future.
no it's the grammar that makes it impossible

"One of the major problems encountered in time travel is not that of becoming your own father or mother. There is no problem in becoming your own father or mother that a broad-minded and well-adjusted family can't cope with. There is no problem with changing the course of history—the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.
The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be descibed differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is futher complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father.
Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later aditions of the book all pages beyond this point have been left blank to save on printing costs.
The Hitchhiker's Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term "Future Perfect" has been abandoned since it was discovered not to be."
That assumes our current timeline is something someone would even want to visit. If I could go back in time it would be major historical events in history. Dinosaurs extinction event, Neanderthals, building the pyramids etc. This year will be nothing more than a footnote in history like smallpox, Spanish flu, bubonic plague, or any dozens of years with disease as a highlight.
Our egos are pretty large to believe this year would be a desirable spot for any time traveler

For all we know time travel only works on some sort of observation-only basis.
Once you introduce the concept of a technology that travels through time, you can start to assume all sorts of wild things about it. If it is truely a "travel to any point in time" device, then any level of possible future tech could be deployed by the interloper. Stealth suits? The ability to phase through matter ala Kitty Pride? Mind manipulation devices that don't require direct interaction?
Time travel is scary. Once it's own the table the rules of engagement we know are all off. How it operates dictates everything going forward (and backwards).

We can't even get people to wear masks in a pandemic - I fully doubt the ability of humans to abide by a temporal prime directive.
The smartphone as you know it was originally invented in 2061.c2
We are in 2020.c43 ( this is the 43rd version of 2020 since the first leadpoint opening)

You can only travel backwards in a parallel plane to our universe where you can only observe but not interact with anything that already happened. If there was some way to cross into the same plane once you get back there you would have already changed that entire plane of existence as soon as you entered it. At that point it's possible that you caused a great deal of harm .
Time is a doorway. It hasn't been opened yet. Once it is opened you can only travel as far back as then since the door isn't opened in the time before it.
Yeah I don't think you should be able to go past the invention of backwards time travel itself. Its like rewinding the tape beyond 00:00.
Stephen Hawking hosted a party for time travelers, but no one came
"I have experimental evidence that time travel is not possible."mashable.com
If I was a time traveler I wouldn't attend Stephen Hawkings party. Cmon now.
One "theory" that I was always fond of is that time travel is possible, but only to the point that time travel became possible. So as soon as you open the bridge between points in time, you can traverse it. You just can't go back to a time when no such bridge existed.
Edit: Beaten, bah
That would be bad. As soon as you turn it on your have trillions of time traveling tourists appearing at once wanting to see the invention of time travel.
Thats the thing with time travel. If possible you have a stupidly massive amount of people at any historical event.
Not necessarily. Time travel can be possible but no one ever achieves it.
Maybe it's actually a split-timeline situation rather than a single continuous one? That could explain why there are no time travelers, assuming a time machine that can travel to before its creation can actually exist at some point. Each timeline would only have a single point where a time traveler would arrive. since another jump would just result into a separate timeline.
Past time travel is possible in two ways.
Record matter in a given space. This process allows one to recreate that space to any time that was recorded. So if a something was captured and recorded, then you could hypothetically clone the object. Assume satellites captured Earth in 2020. In 2060 you could "time travel" back to 2020 by replicating Earth from 2020, in 2060 in a given space. It would need to be at the perfect angle relative to the Sun so it would still be safe to live on.
The other possibility is assuming the universe has a memory and is repeating itself. We might be living in a universe's memory for all we know. A machine to cut universes and slide through a previous (or future) one.

To be fair, do we even know what rules time travel in our universe would work under? If someone changed the timeline, would we ever even notice? Or would the world just change abruptly in a blink, with no evidence to ever show that it happened?
And even more importantly, would it ever even remotely be someone's first priority to visit Stephen Hawking's freaking birthday party? What if time travel is such a risk that visiting something that trivial just to prove time travel exists is pointless? Will anyone even remember the freaking birthday party thing in 50 years, never mind however long such a technology would take to develop? Will Stephen Hawking even have the same kind of pop cultural clout as Newton and Einstein in that same time frame?
If you had a time machine, would YOU go to Stephen Hawking's birthday party? Imagine having all of history before you, with the potential for unimaginable risk but also unimaginable reward. You could visit the start of a religion, the age of an extinct species, the rules of a hundred kings and emperors.
Or you could visit the birthday party of one cynical scientist that may not even be a well-known figure in your time, just to stick it to the man.
What I'm saying is "if time travelers don't come to my birthday party then time travel won't exist" is a kinda wonky premise for an experiment.
He was an excellent physicist. That doesn't mean he was a good predictor of human behavior.

Travel to the future is possible, just not feasible right now. All you have to do to go to the future is travel fast enough to start feeling the effects of time dilation. Or be near something like a black hole that has gravity strong enough to start affecting space-time.
Already been mentioned a couple of times but when we invent time travel the first thing that will happen is someone from the future will step out from the machine.
Play Quantum Break. It has a really solid interpretation of this time travel mechanic. It also has time zombies or something... I should play that game again, I don't remember all of it.

Quantum Break actually had a good time machine concept that explained why we didn't have time travellers yet. The idea is that you can only travel as far back to the moment the machine was first activated. You can't go anywhere or anytime you want, the machine itself is like an anchor and when it became operational, it marked the moment time travel became possible but only from that moment forward and back.
Edit: hah, beaten by Dead Man Typing who time traveled to post before I did.

It's already happened and has been corrected but you wouldn't know that. I'm happy to have helped you live, great-grand father.
*steps over broken glass and scattered razor blades*
Time is a unit to measure the passing of astrological bodies in comparison to the earth. A day is the Earth's rotation. A month is the moon's orbit. A year is our own orbit around the sun.
Time is a measurement of the material world into the fourth dimension, relative to the three dimensions of space.
And if we all woke up tomorrow as immortal robots, that wouldn't change.
A lot of people might decide that bangs and eyeshadow don't make a good fashion choice anymore, though.
If time is a straight line then yes. If time is a web or something else then no. Maybe every time you go back in time it creates a new time line, or you join a timeline that matches like a railway junction. Maybe time scales like a fractal.
Generally I agree though that no one has been able to. Going back in time would require understanding where earth was situated in the universe at the time you are going to. If someone did go back in time there's a high chance they died lost in space.

Travel back in time.
a) Openly declare yourself a time traveller and likely get dismissed as a lunatic OR face the fear of the people of the current time not knowing or trusting your intentions and subduing you so you don't actually interfere
b) Stay incognito and largely end up ineffective at your exact goals because the world is a huge and complicated dynamic system that probably can't be shifted into precise intent with even robust action and resources -- like maybe you try to change something for the better but it just produces a new unexpected problem instead, that may or may not be more severe than the issue you were trying to fix
It could exist but it would never work as easily as you might think.
