If you could travel at 100000 times the speed of light how long would it take you to go to the other side of our Galaxy?

Traveling at the speed of light which is 186,000 miles per second it would take 100,000 years for you to travel across the Milky Way as observed from earth; the Milky Way is 100,000 light years across. However, if you were interviewed upon arrival at the other side, your report would be that the trip happened instantaneously. You would be surprised by this. You would also find it curious that everything you knew before you left has been gone for 100,000 years. This question and its answer are fanciful; relativistic effects are real, but it would be impossible for a human being or any other physical object to accelerate to light speed from being at rest on earth. It illustrates the curious relativistic effect that when you reach velocity 'c', you completely stop moving through the dimension of time, but everything else continues to whizz through the dimension of time at light speed. So that for you, on the trip across the galaxy, the trip would be instantaneous; time would not pass for you as you travel at the speed of light. You didn't know that right now you are traveling through the dimension of time at light speed, did you?

∙ 15y agoAt the speed of light itself you would cross the galaxy in zero time. Time stands still for the subjective observer (the person or object moving) at the speed of light. What it would mean to go faster than c is debatable.
As the galaxy is 100,000 light years across, at the speed you mention an object observer (one NOT travelling) still would not notice you had bridged the gulf in only a year, unless you enjoyed some means of "subspace" communication, as it would take light signals (such as radio waves) 100,000 years to travel from the destination end back to you. Well, 100,001 years...

What is tachyon travel?
Well, tachyons are particles that travel faster than the speed of light. Travel could be referring to how they move across the universe (if they exist) or somehow splitting a object down to the atoms and attaching it to a tachyon particle and sending it through space and time.
Why does light travel more quickly through solids than through gasses?
Light generally doesn't travel faster through solids than through gases. Sound does, but not light.
How do electromagnetic waves travel through a medium?
electromagnetic waves generally don't require a medium to travel. the most commonly visible example is "light" which may be either sun's light, light from a bulb or any other source. they travel as transverse waves.
Can traveling at the speed of light melt iron?
It isn't clear at all what you mean. In any case, it isn't possible to travel at the speed of light - except for specific particles, such as photons (pieces of light), which can ONLY travel at the speed of light.
At its nucleus the Milky Way Galaxy is about 100000 light-years wide and .?
The whole of the galaxy has a diameter of approx 100000 light-years, not just the nucleus! So it is not clear whether the question is about the galaxy or its nucleus.
What is the distance across the milky way galaxy?
Our Milky Way galaxy is 100,000 light years across.
How log could it take light to travel to earth from the android galaxy?
I assume you mean M31, the Andromeda Galaxy. It is approximately 2.5 million light-years from us; that means that it takes light 2.5 million years to travel from there to here (or from here to there).
Which galaxy is the Orion nebula in?
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.
If light travels at 300000kmsec and the galaxy is 100000 light years wide how many kilometers is this?
Answer: 100,000 light years = 9.454e+17 km
If you could travel at the speed of light how long would it take to travel from one side of the Milky Way galaxy to the other?
Between 100,000 and 180000 years.
If you could travel at the speed of light how long would it take you to travel from one side of the milky way galaxy to the other?
Between 100,000 and 180000 years.
What is the total size of the milky way galaxy?
It is a barred spiral galaxy with a diameter of 100000 to 180000 light years, and contains 100-400 billion stars.
How long would it take a light beam to go across a galaxy 50000 light years in diameter and return?
It would take 100000 years.
How fast does light travel from the Milky Way galaxy to the Andromeda galaxy?
299792.458 kilometres per second
How long does it take light to travel from the Sun to the Andromeda Galaxy?
The light from our Sun will take about 2.5 million years to reach the Andromeda Galaxy.
What is the Travel time from earth to another galaxy?
That naturally depends on how fast you plan to travel.We don't have to talk about too many different modes of travel, to show that it's a trip that'snot even worth thinking too much about.If you could travel at the speed of light ... which you can't, because nothing can except light ...the travel time to the nearest galaxy would be 2.24 million years.That's the travel time to the nearest galaxy at the highest possible speed for anything in the universe.
