## Wonder project – Is it possible for humans to travel at the speed of light?

I’ve always been interested in space so I decided to make this project about the possibility of humans travelling at the speed of light. According to my research, all sources say it isn’t possible to travel at the speed of light. Along with this research I also discovered some new things that I didn’t know about. As the speed climbs up of an object, it’s mass increases. Any energy that you put into an object just increases the mass and doesn’t do anything to the speed. Mass and energy are the same thing when it comes down to this theory. This increase in mass is only noticeable if the object is moving very fast and one of the reasons that it is impossible to obtain the speed of light is that the mass of the object would have to be infinity. Time dilation is a theory which explains that time for objects moving very fast is slowed. According to this theory, if you traveled at the speed of 90% of 186,000 miles per second which is the speed of light, your time time would be halved. Some other effects would be that you see a small window like tunnel because of the photons that seem to go forwards. This tunnel will seem blue because of stars crowding together which is an example of the Doppler effect. As you go faster, the Doppler effect becomes stronger until the colour goes off of the visible spectrum or a faded black. Another thing that would happen if you could get an object to the speed of light is that the length would shrink to zero. The length can be calculated by dividing the proper length by the Lorentz factor. If you were the object travelling at the speed of light, you would not get squished and time would tick normally, but if you were watching then you would be able to see and measure the difference. In this theory, everything including time is relevant. In conclusion, I learned that the reason which is making it impossible to travel at the speed of light is that the faster you go, the mass gets bigger and at the speed of light, the mass would be infinite. I also learned the side effects of traveling almost as fast as light and how you would see time compared to others.
