What are your theories on light speed travel? Is it possible or impossible?

Question

Explain please, too. You will find my theory somewhere in this post:

It was too long to fit on the details page.

I am disproving the thoery of light speed travel by the way.

Answer 1

Travelling at the speed of light is not impossible it just holds many problems for one are perception of time would change to adapt for the new speed and when we stopped our surroundings would seem to move in slow motion also travelling at that speed would require a computer to navigate and stop the ship the way we are going to attain the speed of light is by harnessing the power of gravity imagine if you will a ship tug boat the front ship is a nuclear powered gravity field created using super dense metals and elctro magnets for rotation then in the middle is the scientists traders really a ship of any size and or shape then behind it another power plant to stop the whole thing when you arrive at you destination. as the power plant creates its gravitational field it will pull the rest of the ship towards it steadily increasing unil it is turned off then the one in back can be activated to slow the ship to a stop with this design it would not require much power eighthter only the ability to know when to stop so you do not breach the point where the gravitatational field is self powered and unable to be stopped as for the sonic booms that is only an effect that happens inside of an atmosphere where the friction creates a breaking point then explodes outward in space there is not this problem as there is no atmosphere.

Answer 2

It is not possible, since as the speed of light is approached, the mass increases, making further acceleration progressively more difficult (as seen by an observer at a "fixed" point). But the situation is much worse than that: the only way we know to propel a spacecraft is to eject mass from it at high speed, and rely on Newton's third law. The impetus is the momentum of the expelled mass: the mass times the velocity. Although you want momentum, what you have to pay to get it is energy, which increases as the square of velocity. The specific impulse of a chemically powered rocket is on the order of 250 seconds: a pound of fuel gives a pound of thrust for 250 seconds. But to do realistic interplanetary travel (i.e., to get to Jupiter in a few days rather than a few years) requires specific impulse on the order of a million seconds. This means 4000 times the velocity, or 16 million times the energy. This means a thermonuclear reactor, which we have no idea how to build -- and this only gets us around the solar system, not to the stars.

Answer 3

If you are talking about people traveling at light speed, then my answer is that phsicists currently believe it impossible. You need energy to accelerate a "space ship", say. As the speed of the space ship increases, so does its mass. So then it takes even more energy to get the ship moving faster. But its mass keeps increasing as you increase the speed and you end up needing more and more energy just to get the ship moving just a little faster. As you get closer to the speed of light, it turns out that you will need more energy than is in the entire universe to get the ship moving to light speed.

But why bother with light-speed travel? Perhaps we will someday be able to harness a worm hole to get where we want to go even quicker but not needing light-speed. Someday we may be able to form our own worm holes and never need to worry about light-speed.

Answer 4

The limits of the human mind are not at issue here. Perhaps we didn't think we would be, but it was never a physical impossibility. Speed-of-light travel is impossible. As such, there isn't any such thing as a *theory* of light-speed travel; in reality, its no more than a fleeting hope.

Answer 5

completely impossible even if there are aliens they cant even do it it is impossiple if you travel lightspeed you skin would fly completely off it would make any material even diamond melt and if the was somwayy you could completely defy the laws of gravity physics and science and somhow survive 3sonic booms per second u would plunge into complete darkeness and the light that u owont be seeing will be cutting through anything.u would make a rip in space and maybe possibly time

Answer 6

I am one to believe that anything the human mind can conceive is possible. It is surely possible. After all, do you actually believe NOTHING can go faster than light? It was not too long ago a fantasy to travel into space!

Answer 7

it may be possible. but one would have to become light in order to travel at the speed of light. therefore one would have to be able to become light and then to become matter again. this would probably take almost an infinite amount of energy. whoever figures this one out will be a mega rich individual.

Answer 8

Speed of light travel is demonstrated in daily life, turn on a light and see how fast it reaches your eye.

Answer 9

Only photons of elecro-magnetic radiation can travel at the speed of light.

Answer 10

A Fiery horse with the speed of light,
a cloud of dust, and a hearty HI YO SILVER.

AW!!!!
