Holy crap! There are a lot of words in this one! Sorry, I get a bit wordy sometimes. But if you stuck with it all the way through I'm sure you're glad you did, because now you have something freakin AWESOME to think about! At least that's what I hope. I did some hella research on this one, so...if you didn't read it you should.

Oh and I apologize if my past few comics haven't been very funny to you. I guess I'm running low on humor juice. I'll have to stock up tomorrow. Hopefully.

Oh stop apologizing already, I like this one... I am an avid reader of Michio Kaku's books and as such I find this pretty damn interesting.
This page, if the facts would turn out to be true, looks like it could totally go into a school-book. ^_^

on the alt text: if you can manage to get space itself moving (perhaps using a spinning black hole, if that would work) and then travel at sub luminal speeds you can (effectively) travel faster than light and go back in time! (i think, though I'm happy to be corrected)

@ralph: the only thing I don't understand is why approaching light speed slows time down. It seems to me that gravity is the main factor in time-dilation, so what does your speed have to do with it? Unless there is a set speed that time travels at, like the speed of time or something. And if there is, wouldn't going faster make you jump forward? So how would you go backward? I need a lot of time to think.

@effigy_power: haha sorry. *d'oh* i mean...uhh...glad you like it. I haven't managed to get my hands on any books on this subject but I would love to. Kaku is like the current Einstein. Actually, I believe he was on some show on discovery about black holes, which is what got me interested in all this stuff. And haha you're totally right about the school book thing, I didn't even try to do that.

*ugh* I am so damn long-winded! I don't know how not to be.

@ ralph again: oh and Einstein also theorized that planets, with their double-rotation (both axial and orbital), actually kinda grab and drag space behind them, so a spinning black hole might work. maybe. They're weird. I don't think they have any kind of orbital rotation though. Maybe if you kinda slingshot around them? That's really damn risky though.

Oh hey everyone in general: I don't know if any of you have seen this, but apparently NASA sent a probe out to test Einstein's theory that space and time bend, and in 2007 they concluded from the results that he was right! Now they just have to figure out if the other half of relativity was right.

@Ralph: Theoretically sadly impossible. We can't even reach lightspeed, because at that point our mass becomes infinite and that's mathematically impossible for anything but light, which has no mass.
Technically we can only move forward in time, as close to lightspeed suspends us in time in relation to those on earth, for example. Thus when we come out of said speeds, we would have lived 5000 years on earth in a few minutes.
We can't go back in time also because the speed of light is constant from any observer, regardless of the observer's speed. To go back would require light to go backwards, which it can't.

That's also why the hyper-drive animation in Star Wars is inaccurate. Going to hyper-drive would not make the light of the stars motion-blur like that, because the speed of the light remains the same, independent of the ship's speed.

Yes, I am a nerd AND a geek.

Shaggers: I think that as you approach the speed of light you gain more mass. As an object has more kinetic energy some of that energy adds to the mass of the object. This warps spacetime and makes time go slower as you go faster. I’m not so sure about this though (maybe Effigy_Power can enlighten us) because I haven’t read anything on this kinda stuff in ages.

Effigy_Power: The method I suggested does not involve travelling faster than light. It involves travelling at speeds slower than light in space that is moving (perhaps around a black hole) at speeds slower than light that can effectively allow you to travel faster than the speed of light (if the sum of both speeds is above c) without the craft exceeding c whilst travelling in space.

But as I have already said, I haven’t looked at anything like this in ages.

@Ralph: What you are suggesting is actually a theoretical propulsion technique called a Alcubierre Drive.
The ship can move faster than or at the speed of light because it is stationary inside a bubble of space. The bubble contracts in front of the ship and expands behind it. That way relativity isn't shot in the crotch. But it still won't make time go backwards simply because light has only one possible direction. I am no Trekkie or Trekker, but I think that's how the Enterprise get's around, hence the weird length distortion when that thing takes off. The bubble bends the light reflected from the ship.

The thing about speed and mass is correct, higher speeds mean more mass mean more space-time-warp. Again tho... it can only make time theoretically stop at the point of infinite mass, that's why we would never see something actually fall into the event horizon of a black hole, it would be suspended there, because in relation to us, the object's space-time is infinitely long.
Not to mention that if we had infinite mass... we'd be crushed by our own gravitational field.
I have seen people like that come out of IHoP... it's not fun to watch.

PS: I love it when cartoons spark cool discussions like this... that's why I gave it a 5, lol.
And yes, I am sure I am a chick... chicks know stuff too, you know. ^_^
Just kidding.


They really don't.

*ahem* AN Alcubierre Drive. *GRAMMAR NAZI STRIKE!*

haha when I made this particular strip I was hoping it would spawn an interesting discussion.

So...theoretically...if you traveled at the speed of light, would that mean that your gravity would become as immense as that of a blackhole? Or would you just be crushed into nothing...or I guess aether according to tesla.

Well, you'd just be crushed and then basically blow apart from the collision in the middle. You initial mass wouldn't be enough to prevent matter from escaping, for that you need something a few times the size of our sun, which is also going to contract, but then doesn't have enough mass to keep it together and basically fart all over the solar-system.
Basically what I am saying is that your entire mass would be blown apart due to the implosive force long before it can reach infinite values.

And don't gimme grammar, kid. I was too focused on writing Alcubierre correctly. ^_^

Haha nice comic Shags! I like the way you worded it, was funny (^^) Unfortunately I can't contribute to the discussion even though I just finished 1st year physics (TT)

JUMBO JETS!!! *pant* *pant* *gasp*. I was at the licencing centre waiting for my ticket to be called when it suddenly occured to me that jumbo jets go really fast, and they're massive. They should be really slow if this theory were true.

So *gasp* *pant* *pant* Sorry guys. I have to burst your bubble.

Hello by the way, LOVE these comics. Keep up the good work Shaggers.

man, I hate to disagree with someone who just subscribed *and* complimented my comic, but your point is incorrect. A good observation, for sure, however jumbo jets are, perhaps, a couple thousand times bigger than the average human, right? Well, while that's pretty massive, it's not enough to make much of a difference in gravity. See, an ant is around 22 *million* times smaller than us. That difference is so immense that there is a noticeable time difference.

Oh, and just because time goes by something slower than the other doesn't mean it can't move faster. In fact, quite the opposite. Point in case, planets. Planets are freaking massive, but they travel like 30 miles per second (at least the Earth does). Or, keeping with my comic, we can actually travel faster than an ant. The thing that matters is proportion. I think. I'm no expert though.

But hello gunki'drabbit! And thanks for the subscription and compliment! I really appreciate it a LOT.

Personally, that would explain why plain rides seem to go so slooooooooooooooooooooooooooow.

We can go at hundreds of miles per hour in a commercial jet but it still seems like it takes foreeeeeeeeeeeever to get to a place that really isn't that far away. I two hour cross-USA plane ride feels like ten hours long, maybe shorter if you have something to entertain you.

I'm amazed I just typed that, considering my brain is currently located all over the wall.

Also, I'm subscribing ASAP.

Theory seems like BS to me. Honestly an ant and human move different simply by size and leg length to the distance of travel and gravities effect on the body.

If we travel at the speed of light, big woop. We just go really fast, we may damage cells in the universe from the speed splitting atoms and destroying them as they move along but that is just it. Destruction. All I see in this theory is some guy thinks time is effected by how fast and big it is. Bull shit, all it has to do with is the basic pyshiccal properties of our galaxy and perceptions of time and space which is all the same exact thing. Time is standard though so there is no change in it. Just the preception of our own time. Which sure could be effected by the properties of gravity and the structure of bodies but other then that I don't see the theory worth billions of dollar of research.
