There's energy loss in that maneuver, but it's by the planet in that case, so it's not helpful for capture.
020
Daniel Whiteson @danielwhiteson.bsky.social · 27/02/2026
There has to be some kind of energy loss, meaning: friction from gas/atmosphere, or tidal forces, or a 3rd body like a large moon, or colliding with another moon or asteroid.

Daniel Whiteson @danielwhiteson.bsky.social · 27/02/2026
Great question! And your instincts are right. If there's no energy transfer, then the incoming kinetic energy is enough to escape the gravity well. So how does it get captured?

No, the difference is categorical. Massless objects move fundamentally differently from massive objects, even from massive objects moving near the speed of light as seen by you. It's comparing an orange-colored apple to an orange.

Daniel Whiteson @danielwhiteson.bsky.social · 05/02/2026
Third, this argument is tempting because it seems to extrapolate naturally from things moving NEARLY the speed of light, whose time appears to be slow as you see it, to things moving AT the speed of light. The difference is small, right, so we can dot-dot-dot our way from one to another?

Daniel Whiteson @danielwhiteson.bsky.social · 05/02/2026
But light has no experience, because there's nothing it's like to be in light's frame, at rest with respect to a photon.
110
Daniel Whiteson @danielwhiteson.bsky.social · 05/02/2026
So you can't calculate the rate at which time would appear to pass for light, because it has no frame. (And even if you did, it would only be the appearance for you, not the light's experience).
110
Daniel Whiteson @danielwhiteson.bsky.social · 05/02/2026
Second, this works for massive objects, which have inertial frames, frames where they are at rest. That's baked into the calculation, no avoiding it. Light has no mass and no inertial frame. There's no speed or frame in which light is at rest.
110
Daniel Whiteson @danielwhiteson.bsky.social · 05/02/2026
First, velocity is relative, and so is time dilation. The closer you get to the speed of light, as seen by someone else, the slower your time appears to pass as seen BY THAT OBSERVER. Your experience of time is unchanged. (It has to, since you have many relative velocities)

This is a commonly repeated bit of sci-comm, because it sounds delicious. But I think it's misleading.

No, it doesn't make sense that a star predates the Big Bang. Note the large uncertainties on the age -- likely there's a lot we don't know about star formation in the early Universe.
