Can you time travel if you go faster than light? Therefore, it is only light that can travel at the speed of light – because it has no mass. The takeaway: Travelling at speed can change your experience of time, but...
Is 99% light-speed possible? Yet all across space, from black holes to our near-Earth environment, particles are, in fact, being accelerated to incredible speeds, some even reaching 99.9% the speed of light. One of NASA’s jobs is to better understand how...
How fast does time travel at the speed of light? This case is sometimes called special relativistic time dilation. The faster the relative velocity, the greater the time dilation between one another, with time slowing to a stop as one approaches...
How long would it take to get to Alpha Centauri at 99% the speed of light? If you were able to travel to Alpha Centauri, roughly 4.25 light years away, at 99.9 percent the speed of light, you’d be able to...
How do you calculate time dilation? The time dilation formula is given by, T =T0 /√1−(v2/c2) T is the time observed. T0 is the time observed at rest v is the velocity of the object. c is the velocity of light...
Can Voyager 1 still see Earth? Voyager 1 is vastly too faint to see, even with the most powerful earthly telescopes. Is Voyager 1 still active today? Launched 16 days after its twin Voyager 2, Voyager 1 has been operating for...
Where exactly is Voyager 1 today? Voyager 1 is currently in the constellation of Ophiucus. Where is the Voyager 1 now 2022? The probe launched on Sept. 5, 1977 — about two weeks after its twin Voyager 2 — and as...
What is an asteroid belt? The asteroid belt is a region of space between the orbits of Mars and Jupiter where most of the asteroids in our Solar System are found orbiting the Sun. The asteroid belt probably contains millions of...
What is the size of solar system? We took the radius of the solar system to be 39.5 AU, which means it has a diameter of 79 AU. This means you could put the Solar System about 3440 times between the...
Is the Oort Cloud 1 light year? The Oort cloud is thought to occupy a vast space from somewhere between 2,000 and 5,000 au (0.03 and 0.08 ly) to as far as 50,000 au (0.79 ly) from the Sun. Some estimates...
