Why can't a spacecraft with the speed of light can be made?

Answer 1

No!

Except - when the universe fist formed, the universe exploded and moved hundreds of times faster than the speed of lights

_________________________ Light speed is impossible for an object that has mass for two basic reasons:

1) As your speed grows, your mass also grows, and at the speed of light (c)

you, or anything with any mass, would become infinitely massive.

2) The more mass you have the more energy needed to accelerate and with an

infinitely massive object you need an infinite amount of energy to increase speed.

So c is a universal speed limit which nothing can exceed you can however

manipulate space time to beat light to a destination without moving very fast or

in some cases not moving at all.

Now that you understand how that all works, let me tell you something really

mind boggling for you to think about. If you have ever been running and thrown

a ball in front of you at the same time, you would view the ball traveling a certain

speed away from you, but an observer at rest, watching the ball would believe

that the ball is moving fast.

Say the runner is running 10 m/s and they throw the ball 5 m/s relative to their

speed. The real speed of the ball relative to a person at rest would be the

combined vectors of the runner and ball, or 15 m/s, so one would think this

simple math concept would apply to any speed.

One might extrapolate this concept to deduce that a ball thrown at 5 m/s from a

ship traveling 1 m/s less than the speed of light would be traveling 4 m/s faster

than the speed of light. This is a common misconception with light, but light

moves at a constant rate. Simply put, nothing can travel over 3.0x108 m/s. This

is related to the fact that all of the things we use to measure with ... rulers,

clocks, scales, etc. ... change in proportion to their speed when they move.

Particles called tachyons are said to travel faster than the speed of light, meaning

they can arrive in a place before they depart. Tachyons do not compose any of

the normal matter that makes up the earth (quarks and leptons -> protons,

neutrons, and electrons -> atoms and molecules).

Tachyons are theoretical sub atomic particles there is no proof of their existance

Answer 2

According to the theory of relativity, objects with mass cannot reach or exceed the speed of light in a vacuum. As an object with mass approaches the speed of light, its energy requirements for acceleration increase towards infinity. This would require an infinite amount of energy, making it impossible to achieve the speed of light.

Answer 3

There is one thing I know of. This relates to Einstein theory of relativity and black holes.

According to The theory of relativity, space is not empty it is a fabric called space time. This also relates to orbit, all objects are meant to travel in straight lines it's the bending and warping of space time which makes the object bend. What you need to bare in mind for now is if space is a fabric called space time according to Relativity.

Because black holes are made up of so much mass in such a small space, the very fabric of space time bends and gets sucked by black holes. Long story short, if you want to know more about this you should research into it.

The point is that space travels faster and faster into the black hole the closer you get to it. Eventually you get to a point called the event horizon, this is the point at which you stop seeing light and just see the black of a black hole. This is because at this point, space is getting sucked into the black hole faster than light, which is why you can only see a black hole, as of the name 'Black hole'.

Answer 4

Humans (as well as other objects with mass) can't travel at the speed of light because as an object travels more quickly, it's mass increases (this increase is not very significant until you begin to approach the speed of light) therefore, the energy it takes to accelerate the object also increases. To reach the speed of light, the object's mass would have become infinite, and so the energy it would take to bring it to that speed would be infinite and impossible to acquire. Light can travel at such speeds because it has no mass.

Answer 5

According to special theory of relativity no body can be accelerated from Rest to more trhan speed of light. A body as it approaches the speed of light its mass increases and thus would require infinite energy to reach speed of light.

Answer 6

In fact, the farthest galaxies we can see are receding at several times the speed of light. While moving above the speed of light is forbidden in the Special Theory of Relativity, in this case it is space itself that is expanding at that speed.

Answer 8

In a vacuum, photons will only ever travel exactly at the speed of light. They can't go slower, and they can't go faster. Note that going faster than the speed of light would violate causality, so this is usually deemed impossible.

Answer 9

because of the forces that would be pressed agaist the matirials used would crush the space craft and nothing can beat the speed of light

Answer 10

It is entirely possible for a spaceship to reach speeds 99.99999999% the speed of light; it is just impossible to attain the full 100%.
