Light is the fastest phenomenon in the universe, clocking in at just under 300,000 kilometers per second. The telescopes that observe that light, from radio waves to gamma rays, are built at rather ...

Could we send a spacecraft to a black hole? This is what a recent study published in iScience hopes to address as a team of researchers investigated the feasibility of sending a spacecraft at the ...

Light travels unimaginably fast, zipping across the vacuum of space at nearly 300,000 kilometres per second. This figure is so fundamental that it's used as a cornerstone in modern physics and ...
