How To Build A Time Machine (DON'T TRY ON LIVING CREATURES- YOU WOULD DIE!!!!!!!)

First you need to travel at lightspeed. If you do this for 30 minutes to one hour you can travel 60-120 minutes into the future, but not the past. To travel at the speed light you would have to attach to a photon or stay on one somehow. If a typical photon is 500 nanometers (according to one of the links below) you could use thousands or millions of photons together to travel at light speed. You would also likely have to either be standing on them or holding them. You would probably have to use solid light, which is a hypothetical material (link below). There may be ways to freeze light (also theoretical) which would have to be done.

"
In theory, photons, the particles that make light, could be attracted in a nonlinear medium. In test, a laser beam fired into an extremely cold cloud of rubidium slowed down the photons and made them act as a single entity.[7]"

"For one, the person traveling at such a speed would experience a slowing of time. For that person, time would move slower than for someone who is not moving. For example, if a person is traveling at 90% of the speed of light, then that person would experience only 10 minutes of time passing, while a stationary person would have experienced 20 minutes. Time will be cut in half!"

"In this way you could say the “size” of photon is basically the width of its wavelength. The wavelength of green light is about 500 nanometers, or two thousandths of a millimeter. The typical wavelength of a microwave oven is about 12 centimeters, which is larger than a baseball."
