How could traveling the speed of light lead us to time travel?

In a question, someone answered that if we were able to travel the speed of light, then we could somehow achieve time travel. How would this happen?

Also, how could we make time travel possible? Is there some formula to it? I think time travel is a really awesome concept, and I want to learn more about it.

SpaceTime is the 4th Dimension
The faster you travel through it the faster time passes by.
Curving spacetime causes time to slow down
Earths mass effecting spacetime causing a curve

But in reality it is 4D so the curve is more like this:

The time in empty space travels faster than time on Earth due to Earth causing a curve in spacetime

Its like this the curve means more space for something to travel across ie time where as a smooth spacetime takes less space for something to travel across like someone running across a valley while another runs across a flat surface.
Traveling faster is like running faster than someone else you will get to the finish line before them ie travel faster in space youll be in the future before the time you would if you went slower.

TRaVEL..:)?

is there any specific baggage that they allow and not allow and what should i expect wheni get to the airport?
plz help!!

Are you referring to the size and weight of your luggage or what you can pack?

If you are referring to size and weight, each airline sets its own policy and it may be different for an international flight than it is for a domestic flight. You will have to check the website of the airline that you’re flying to determine this. Many airlines now charge for a second checked bag and a few charge for all checked bags. You will also find that information on the airline website.

Prohibited items in checked baggage can also be found at the airline website. Prohibited items in carry-on luggage can be found at the TSA website by following this link:
