Why you are not able to reach at the speed of light although there is nothing in physics which stops us from doing this?

If you think that nothing in physics prevents objects having mass from moving at the speed of light, then you are over 100 years out of date on your physics. Special Relativity is the part of physics that prevents this.

∙ 9y agoThis question is based on a false premise. You assert that there is nothing in physics which stops us from doing this. Where did you get that from? That is wrong.
Since you mention physics, you should be aware that you need a force to accelerate a body. Einstein's theory shows that as your velocity increases, the force required to accelerate you also increases. As you approach the speed of light in vacuum, the force required to accelerate you increase. In the limit, you will need an infinite amount of energy to take you to the speed of light in vacuum.
Having said that, light does travel slower in other media - only a quarter as fast in germanium. So it should, in theory, be possible to propel you at that speed - but through vacuum or air, not germanium. However, the energy required to accelerate you to that speed would still be unimaginably huge.

Is the sun faster than the speed of light?
Nothing travels faster then the speed of light (according to our understanding of physics)
Who is at fault when a driver slides on ice and hits a car stopped at a light?
The driver that slid on the ice of course, because although it was an accident, the driver at the stoplight was doing nothing wrong, while the one on ice slid into him/her.
Is light at the endof a tunnel a metaphore?
No matter what you are doing, at the end of your journey there will be light. Nothing else. You get there, and there's just a flippin light chillin' at the end.
What travels at 380000 kilometres per second?
Nothing. Or at least, nothing that we could ever detect. The problem is, the speed of light is 300,000 km per second, and your speed is 80,000KM/sec faster than that. According to our current understanding of physics, nothing material can travel AT the speed of light.
What branch of physics deals with light and the interaction of light with matter?
You're asking about two different branches of physics. Optics is the study of light. The interaction of light with matter is more properly Solid State Physics.

Uses of physics to the environment?
Physics governs everything in the environment! Without it, nothing would function. Without physics, atoms and molecules would not exist or be able to interact, which would mean nothing would be able to live or exchange energy (another physics term), which would mean there would be no environment! Speaking in terms of learning physics for environmental purposes, it can be used to calculate heat changes, how a climate will differ from year to year, or simply how light refracts into a rainbow.
What is the physics in kaleidoscopes?
The main relevant physics in this case is reflection of light.
Will car pass emissions in Illinois with airbag light on?
The airbag light would have nothing to do with emissions. If they are doing a safety inspection, it would fail.
What are the physics of primary colors of light?
the physics colours are red green and blue
How many conners does it take to put in a light bulb?
70000000000 because he would sit on a couch doing nothing
What is physics used for?
every thing in the world is physics .what we are doing is physics.use are tht we can know the scientific reason of how actually light came from ,how car moves,can a body have constantspeed and still be accelerating. every thing in the world is physics .what we are doing is physics.use are tht we can know the scientific reason of how actually light came from ,how car moves,can a body have constantspeed and still be accelerating. every thing in the world is physics .what we are doing is physics.use are tht we can know the scientific reason of how actually light came from ,how car moves,can a body have constantspeed and still be accelerating.
