The speed of light.
In sci-fi movies and TV shows, spaceships travel between planets and across space in a matter of seconds, because they can travel at many times the speed of light. So natuarally all we have to do to travell across the universe is to go faster than the speed of light. But this not possible, when something accelerates it increases in mass making acceleration more difficult. When something gets close to the speed of light the mass is so great there is not possible to make it go any faster. After i heard this i thought 'so why can light travel at the speed of light' i was told it was because light has no mass, which sounded like a reasonable reason. But when i thought about it some more i remembered that light is sucked up by black holes, so how can gravity have an effect on something with no mass? can anyone help?

See this link for an interesting explaination to your question. It may not be correct or even provable but interesting none the less.

matter does not necessarily need mass. Light is simply a collection of particles known as photons, they exist, can be observed and of course collected.
