Goodaltgamer: um, actually, the
brontosaurus does exist? (If I understand you correctly)
Even if it did (the jury's still out on that one), it's still classified as another type of Apatosaurus.
PetrusOctavianus: Even with a spaceship capable of traveling close to the speed of light it would take at least 30,000 years for an astronaut to reach the other side of our galaxy.
Um, actually, it should take way longer than that. The other side of our galaxy is at least 300,000 light years away (or was it 100,000? I forget, but either way, it'd take longer than 30,000 years).
