Therefore, objects with mass cannot ever reach the speed of light. If an object ever did reach the speed of light, its mass would become infinite. And as a result, the energy required to move the object would also become infinite: an impossibility.
Firstly, the physical consequence of traveling at the speed of light is that your mass becomes infinite and you slow down. According to relativity, the faster you move, the more mass you have. The same works on Earth when you're driving down the freeway.
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.
So, one minute would be 1176hrs, after hour of your travel - 70560hrs on Earth… so, after you travel for 24hrs, at Earth it' would be 1639440hrs since you been gone... and that is around 193 years. Does it mean that I can travel in time if I can go nearly at the speed of light?
In a world-changing breakthrough in physics, NASA engineer David Burns has recently conceptualized an engine which can theoretically accelerate to 99 percent of the speed of light - all without using propellant, as per international reports.
In order for you to stop time, you would have to be traveling infinitely fast. Nothing can travel faster than light (let alone infinitely fast) without gaining infinite mass and energy, according to Einstein's theory of relativity.
While 1% of anything doesn't sound like much, with light, that's still really fast – close to 7 million miles per hour! At 1% the speed of light, it would take a little over a second to get from Los Angeles to New York. This is more than 10,000 times faster than a commercial jet.
Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light.
Normal humans can withstand no more than 9 g's, and even that for only a few seconds. When undergoing an acceleration of 9 g's, your body feels nine times heavier than usual, blood rushes to the feet, and the heart can't pump hard enough to bring this heavier blood to the brain.
Time Travel
Special relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.
So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.
Elon Musk IQ is close to this starting point, with an estimated score of 155. The typical genius has an IQ of around 140.
Albert Einstein's special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s.
How far is a light-year? The speed of light is constant throughout the universe and is known to high precision. In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766).
The Theory of Relativity says the speed of light is the only “constant” value in the universe. Even space and time can change depending on our frame of reference. The Bible says, “God is Light” and repeatedly uses the word “light” to describe God, who, like the speed of light, is also unchanging.
So light is the fastest thing. Nothing can go faster than that. It's kind of like the speed limit of the universe.
Going faster than the speed of light
Astronomers agreed that the black hole was spinning really fast, but obviously not as faster than the speed of light — the universal speed limit. Yet, Chandra's X-ray data showed that M87 was spinning between 2.4 to 6.3 times faster.
The half-life of xenon-124, one isotope of xenon, was recently measured to be a trillion times longer than the age of the universe! This is the slowest process ever measured by direct observation. You might well ask who measured such a slow process.
“Based on the physics that has already been accrued, velocities beyond 10% the speed of light will be very difficult to achieve,” Millis says. “We are not in danger yet.
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
Infinite means never-ending, and so in this case, time will never end. But, if dark energy is too strong, it will cause the universe to expand so fast that everything in it – even the tiny atoms that are the building blocks for every single thing in existence – will be ripped apart.
Time as a proportionate to memory
So, why does time go so fast as you age? Put in the simplest terms, one of the most prevalent explanations is that our perception of time is inherently linked to how much time we have already lived - ie the older you get the more memories and experiences you have to draw on.
But developments in physics suggest the non-existence of time is an open possibility, and one that we should take seriously. How can that be, and what would it mean? It'll take a little while to explain, but don't worry: even if time doesn't exist, our lives will go on as usual.
