Wikipedia simply states that :" Matter cannot quite reach the speed of light, as this would require an infinite amount of energy (according to the special theory of relativity"
So lemme try to explain why as a non-physics nerd.
So the basic formula that dictates the speed of something is found in F=ma, or the second law of thermodynamics. Which translates to "Speed equals to how much energy is used to push an object of a certain mass, more mass, more energy needed".
It can be drawn to a graph function and if you extrapolate the numbers to reach the speed of light or 299,792,458 m/s, the energy needed would reach infinite with just a mass of 1 gram. Light traveled at c (light speed) because photons are neither matter nor a wave, so does not have weight.
the physics gets super complex as you explain more but basically, to reach the full speed of light with something that weights merely 1 gram, you will need the entire energy of the universe.
But them, science is never dogma and new observations will always change the way we understand this universe better. Perhaps we humans in the far future can find a way to "circumvent" known laws of physics and achieve light speed.. Perhaps..
But since it's now already 2018 and we still dont have real hoveboard tells alot about how fast are we actually innovating, I wont hold my breath to wait for the day FTL speed is made possible.
Yes ... It is possible to achieve the speed of light but to travel (as travel takes more than a single instant/moment/second) with it is a quite different story.
According to the Special Theory of relativity, when the speed of a moving body (mass) reach to speed of the light its mass becomes infinite. Mass of the moving body is called *Relative Mass* while the mass of a body at rest is called *Static Mass*.
Formula for the Mass is:
mrel: Relative Mass
m0: Static Mass
v: Velocity/Speed of the moving body
c: Speed of light
As you can see when the speed of the moving body reaches to the speed of light the denominator (value below the line in the square root) will be equal to zero and it will make the mass infinity.
Now, the problem is that we don't have any technology that can keep mass in its original form/shape while moving with the speed of light so ... Not Possible.
But ... There is another theory.
Most of us would have watched Star Trek movies/series (I am a big time fan of Star Trek movies/series). In these movies/series, you must have heard of WARP Speed. It based on moving the space around an object rather than moving the object itself. Where the body/object/mass remains in rest and its surrounding space moves with the speed of light and/or more than the speed of light, ultimately mass doesn't become infinite.
Even though, many researchers/scientists are trying on this theory but so far it is only a fictional theory nothing more.

hahaha That's quite an interesting question But A very simple answer to this question is no!
no we can't travel with the speed of life,
This question may be arises due to the super man cartoon that we had seen in our child hood, in the super man cartoon, the character runs even double the speed of bullet to catch it in the space/ air :P but that was just illustration and have no contact with the reality :P There are many scientists who study on this topic, Even Einstein also did some research on it. Here i am quoting some information that could be beneficial for you.
> if Superman were to chase a light beam at half the speed of light, the beam would continue to move away from him at exactly the same speed.
I don't have any idea but I do have a theory that you could pass speed of light. Now think about this. As light passes by a black hole or super massive thing in space the fabric of space/ time is bent causing the light to travel around it. So in theory if you were traveling at the exact speed of light but you can mke you path go straight instead of around the object you would get to the end destination before the light that had to go around. Think of it as driving through a tunnel instead of around the mountain.
If you travel at 99.5% of the speed of light, pulling back on 25 December 2015 for quite a while in a round course and return to Earth, you will fundamentally have made 5 years, yet every other individual on Earth will have made 50 years and the date will be 25 December 2065. You have in this way gone into what's to come. If you went in a straight line, you will have accomplished a point 50 light a long time from earth. For the social affair on the space dispatch, they would have experienced travel at 10 times the speed of light. So as demonstrated by them, they voyaged snappier than light.
You can't accomplish the speed of light since you have mass, as cleared up different events on Quora in different posts.
However, on the off chance that we make enhancement like the , we will constantly have relativistic time development impacts and important oddities between the time experienced by our space dispatch social events and whatever is left of mankind remaining on Earth.
Look at it in this way: When you travel in space, the snappier you go, the more unmistakable significance you have to apply on your space ship to extend your speed. Pushing toward the speed of light, your relativistic mass (or hugeness) increments quadratically. For you as an onlooker on your space pass on, you are stationary and whatever is left of the universe is flying past you at close to the speed of light. To vivify snappier, you have to widen the speed of the entire universe, with its mass, to go speedier. That is clearly awesome. That is the reason, for paces to ever approach c (light speed), you should affect a move around your space to pass on that is totally removed from the straggling stays of the universe and that air pocket will now be your entire universe. By then it ends up being more achievable to consider reviving that bit of room by bowing space around that air take, yet your space send inside it truly remains stationary.
In that lies the issue. To "twist space around your move" by getting the space previously and broadening space behind your private space ascend to make a wave to then race into the future, will require a superb degree of centrality. The best current models require an engine and ship produced using awesome issue with negative mass what's more centrality proportionate to the 100% beneficial qualification in 700 kg of mass particularly to significance.
Those two factors alone require headways that are maybe still a significant extended period of time from being made, managed and controlled.
I wish it was not by any stretch of the innovative capacity. I am as energized as you radiate an impression of being about the probability of humankind moving to a honest to goodness spacefaring creature groupings. The mechanical hindrances are colossal in any case. I will cheer with you when an elective technique for making a trip to the stars is found and our first interstellar space dispatch is moved.
ahh man thats the prettiest question for answer i like your thinking.
No, I don't think so. Be that as it may, a hundred years after the fact - who knows?
All things considered, with the as of now accessible innovation, the appropriate response is NO. How about we investigate the quickest man-made protest ever. You'd envision it was a shuttle or a rocket. No. Trust it or not, it was a MANHOLE-COVER!
On August 27, 1957 - at the New Mexico (USA) Nuclear Test Site, a bomb was exploded in a 1.20-meter dia gap in the ground 150 meters down, secured with a 100 mm thick strong steel top - much like a sewer vent cover. The impact in a split second vaporized the whole multi-ton solid stuff in the gap and shot it up the tube as a multi-ton wave of a vaporized issue at to a great degree high temperature, weight, and speed. The pole had, as a result, turn into a huge weapon barrel with the vitality of billions of kilograms of TNT.
As it occurs, a rapid film camera was recording the occasion and was required to catch in moderate movement the way and speed of any ejecta from the gap. Sadly, the camera, which had a significant wide perspective of best of the gap and the zone around or more, recorded the "sewer vent cover" on just a single edge. There was no breakdown of the camera, it's simply that the "sewer vent cover" impacted outside of anyone's ability to see so quick that the camera just observed it for one casing. Later figurings demonstrated that the up until now ordinary four-foot metal circle had been propelled at six times Earth's departure speed. That is around 250,000 km for every hour! 70 km for each second! Nine times quicker than the Space Shuttle, six times quicker than the quickest moon rockets. Quicker than the Voyager shuttle, which, having come to more than 56,500 km for every hour, are currently leaving the nearby planetary group and have for a considerable length of time been professed to be the quickest man-made questions ever. The "sewer vent cover" in a small amount of a second, accomplished in excess of four times the speed it took Voyager 1 decades to achieve.
It was the first run through for a question consume and deteriorate while going from the surface of the Earth!!
I made reference to this to tell you that 250,000 km for each hour is the quickest that a man-made question has ever achieved even with the assistance of an atomic blast.
The main way space explorers can securely go at significant speed is by utilizing a "Relativistic Rocket" that quickens at 1g. In two years of shuttle time (about 4 years of Earth time) it would have achieved somewhat more than 90% of light speed. The issue is, such a rocket would require a gigantic measure of fuel for a voyage. We have to endure till researchers discover more proficient fuel.
In this manner, it appears to me, the best blend of the rocket, fuel, and whatever remains of it might just have the capacity to drive a shuttle to around 50,000 km for each hour and not more.
did you get that chuuuckie? :D
