Do you know about bodies travelling at the speed of light in the universe?

Question

My name is Shaumik Daityari. I am an Indian. I will be 14 on the 25th of this month.
I study in ninth standard. My name is Shaumik Daityari. I am an Indian. I will be 14 on the 25th of this month. I study
in ninth standard. I am enjoying my summer break in my aunt's house. I think there may be bodies travelling at the speed of
light. But according to Einstein's Theory of relativity, if anything travels at the speed of light, its
mass will become infinity. So, now if we apply the Newton's laws, that body will attract
the other objects in the universe so much that everything will collide with each other
and the whole universe will be destroyed.If you could please give me some information,
I will REALLY BE GRATEFUL TO YOU... Please mention your e-mail address and your nationality
as I have never mixed with others. If you are an Indian, no need to mention your nationality. Please contact now.

Answer 1

Hai Shaumik
By Einsteins energy mass relation E=mC^2 , but mass is inversely proportional to velocity
A body with small mass have high velocity compared to a body having greater mass. This implies that a body having zero mass moves fast. There is no such object having zero mass. so no body can move with greater or equal to velocity of light

Answer 2

~Namaste, Shaumik: Bodies cannot travel at c, the speed of light. Only light can travel at that speed, and possibly a few subatomic flashes like quantum particles travel instantaneouslty.

But it would take infinite energy to move a body of any mass at c, and the object woulde keep getting more massive as you approached c.

This is all according to Einstein, and is purely theoretical. The speed of light is the maximum speed limit for objects in our universe, and time passes at different rates, as different object move at different speeds, for and around those objects.

At lightspeed, time stands still.
At sublight speeds, it passes slower and slower, until with no motion, all change is temporal.

Answer 3

Am an Indian too!! Mail me and I'll tell you my real name.
Coming to your question, there actually are some bodies which do travel at the speed of light. Such bodies are not yet classified as matter or photons(light). As to the Newtonian and Einstein's laws, they are not applicable to the space science. You will find many cosmic phenomena that defy these guys' theories.
Good luck in your researches and contact me if you find any satisfactory answer. I'll be glad to know it.

Answer 4

Newton's laws don't apply to the Quantum universe, so on a sub-atomic level, or at speeds approaching the speed of light, they no longer hold true. Thank goodness!

Answer 5

Nothing with mass can travel the speed of light. If you were to travel at the speed of light your mass would not become infinity it would be non-existent.
