Gravestone with a Woman and Her Attendant; Unknown; (Delos?), East Greece; about 100 B.C.; Marble; 94.6 x 120.7 x 21.6 cm (37 1/4 x 47 1/2 x 8 1/2 in.); 72.AA.159

People have been obsessed with time travel for at least the last 100 years or so, and it's pretty easy to see why. The unlimited possibilities of time travel are very enticing.

Ever since Albert Einstein revealed his theory of relativity to the world in the early 1900s, people have been trying to find a way to travel through time.

To not get too scientific here, the theory basically just says that time is relative and it can vary depending on your speed through space.

That means, according to Einstein's theory, that time can slow down or speed up, depending on how fast you move toward something else.

Confusing enough for ya? Well, hang on. We'll get to the fun stuff in a second.

I'm gonna need you to stick with me here. Picture you have a spacecraft flying through space, and it can go faster than the speed of light somehow.

The gravity created by the mass of that spacecraft moving through space at an extremely high velocity could theoretically bend the fabric of space-time around it. Therefore, time travel is theoretically possible. (If you have a vehicle that can exceed the speed of light, which we don't...yet.)

And now that you got through that, and we have established that time travel could theoretically be possible, we get to the fun stuff.

The conspiracy theories...

There's no way the Ancient Greeks had modern technology, right?

Right!? I mean, we're fairly sure, but this sculpture from the J. Paul Getty Museum is tripping the Internet out.

I mean, of course it's not a laptop.

...right?

Look closely at the item being examined by the giant to the right.

At first glance, it looks like a laptop complete with USB ports, but historians say it's something else entirely.

The sculpture, dubbed "Grave Naiskos of an Enthroned Woman with an Attendant," depicts a woman simply touching the lid of a chest, historians say.

Well, that's kind of a downer.

Of course, even if the laptop theory really were true, you wouldn't be able to do much with it. We're pretty sure Ancient Greece wasn't equipped with WiFi.

"You mean I brought this laptop all the way back to Ancient Greece and there's not even any WiFi here?!"

Luckily YouTube conspiracy theorist StillSpeakingOut is keeping things lively with this video.

Social media has its own theories, like this YouTube commenter who applied Occam's razor in a very convincing way. And just because there wasn't a laptop in Ancient Greece doesn't mean that there hasn't been time travel before... right?

Well, probably not. But this one curious Egyptian hieroglyph has some people thinking that perhaps they were visited by time travelers.

The two objects on the right sure do look a lot like either a plane or some kind of spacecraft.

The hieroglyphs have become known as the "helicopter" hieroglyphs in many conspiracy theory circles.

And the two objects definitely look like aircrafts, but the insects on the left raise more questions.

A somewhat common theory behind all of this is that the Egyptians were visited by some kind of "higher race."

And that race shared some of their technology with the Egyptians and helped them build the pyramids.

However, the most logical solution is that this is simply a fake.

via: RAINISCOOL

According to the RainIsCool website, the weird, futuristic hieroglyphs are the result of accidentally overlapping the name of one Pharoh with another.

And when you examine the images, that explanation makes the most sense.

But there are still those who believe we have been visited by time travelers in the past. What do you think?
