Tachyons. In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light.

Is it theoretically possible to travel faster than light?
Tachyons. In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light.
How do you calculate the G of the earth?
we multiply the Gravitational constant G = 6.673X10^-11 by the earth’s mass divided by the earth’s radius which will give us F/m2 = acceleration derived from the formula F = ma.
Is space exploration worth the money?
Manned space exploration is absolutely worth the investment. It’s not just about what we learn out there in space, or about ourselves, or how to be a better steward of precious Earth. It’s about how we live here on Earth together and what type of future we want for ourselves and children.
What is the most dangerous thing in space?
Death by black hole Black holes are expected to form when a massive star dies. After the star’s nuclear fuel is exhausted, its core collapses to the densest state of matter imaginable, a hundred times denser than an atomic nucleus. That’s so dense that protons, neutrons and electrons are no longer discrete particles.
Do you feel gforce space?
This situation represents a human in a gravitational field without a floor—such as a person in free fall or an astronaut in orbit. Since there is no spring compression, you (the human) would feel weightless. And yes, this is why astronauts feel weightless in orbit even though there is indeed gravity in space.
What is value of g’on moon?
approximately 1.625 m/s2
Why should governments spend money on space exploration?
Space exploration is a better use of money than the military is. The government spends lots and lots of money on the military (in the billions), on getting better guns, better air forces, better weapons. It’s a much better use of their money to explore what we don’t know.
How many G’s before you die?
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. Your vision narrows to a tunnel, then goes black. If the acceleration doesn’t decrease, you will pass out and finally die.
What is the disadvantages of space exploration?
There are cost considerations to look at with space exploration. The cost of exploring space is one of the biggest criticisms of the efforts to launch a program that takes us beyond our planet. Manned missions in our solar system could cost 10 times that amount, and that might get us to Mars or one of Jupiter’s moons.
